Building renovation - a job for the experts

… renovations are complex activities. Renovations rely on architects’ ideas and expertise in energy, fire protection, accessibility, safety, and listed buildings. © GEZE GmbH Topics Sustainable architecture in existing buildings: renovating buildings instead of demolishing them Is your building getting a bit outdated? Perhaps it has an old heating system, leaky windows, or virtually no insulation? If that sounds familiar, you might want to consider a building renovation. You could insulate it with contemporary heating, for example, or include modern technical building systems and floor plans. You need good renovation plans and decent funding to improve the energy efficiency and design of a building. Maintenance and modernisation of existing buildings GEZE door technology for the entrances to the renovated Sihlpost in Zürich. © Lorenz Frey / GEZE GmbH There are many buildings in Germany that are not equipped with state-of-the-art technology. The result: high levels of energy consumption, high heating costs, reduced quality of life – and harm to the climate and the environment. The majority of buildings in Germany were constructed prior to the first Thermal Insulation Ordinance in 1978, As a result, they are now often in need of refurbishment, at least in terms of the building's energy consumption, as defined in the Building Energy Act (GEG) on energy saving and the use of renewable energies for heating and cooling in buildings. Building renovation refers to the structural and technical restoration, renovation, restoration or modernisation of one or more floors or an entire existing building. On the one hand, it can focus on maintenance, but also on resolving flaws (partial renovation). Often, antiquated equipment and the technical building systems are replaced and supplemented by a contemporary and modern design (full renovation). Windows and doors play a major role in building renovations As part of a building renovation, the outer shell of a building, walls, roof, and floors are often fitted with thermal insulation. In addition, windows and doors, the heating system, electrics and sanitary installations are most frequently renovated, replaced or exchanged in existing buildings. Energy-efficient building refurbishment pays off Energy-efficient building refurbishment is an important component in achieving the climate targets of the German Federal Government and the EU. More than 18 million residential buildings and around … non-residential buildings in Germany (e.g. office buildings, company buildings, hospitals, schools, universities, sports centres, theatres, and churches) should be pretty much ’climate-neutral’ by 2050, meaning they will produce virtually no CO2. In fact, energy renovation costs for non-residential buildings are amortised relatively quickly, as they often have higher energy requirements than residential buildings. Professional building renovation and modern technical building systems can sometimes reduce energy consumption by up to 80 per cent. The state also helps with renovations of residential and non-residential buildings via KfW Bankengruppe: subsidies in the form of loans and grants are available for complete refurbishments or for individual measures such as insulation, replacement of windows, air conditioners and building automation . KfW funding for building renovation Via the Kreditanstalt für Wiederaufbau (KfW), the German Federal Government supports building renovations for private individuals, companies, and local authorities in the form of loans or investment grants. The basic prerequisite for funding is that the refurbishment measure leads to the KfW Efficiency House standard. The KfW Efficiency House is a technical standard that KfW uses in its promotional programmes. Different numerical values indicate how high the annual primary energy requirement of the existing property is in relation to a comparable new building. The lower the number, the higher the energy efficiency and the higher the subsidy. For companies and self-employed workers KfW energy efficiency programme - energy-efficient building and renovation (reduce energy costs in commercial buildings) For private individuals Energy-efficient renovation (for renovation to a KfW efficient house or individual energy-related measures) Age-appropriate renovation (measures for reducing barriers and safeguards against burglary) In addition, there are also KfW subsidies for smart home systems as part of age-appropriate renovations, or as an additional measure when carrying out energy-related renovation work. For communities, municipal and social enterprises Energy-efficient building and renovation (for energy-related renovation of existing buildings within communal and social infrastructure, no residential buildings). Barrier-free town (for barrier-reducing measures, via which existing communal and public buildings, traffic facilities, and public spaces can be renovated in an age-appropriate and family-friendly manner.) Energy efficiency advice is also subsidised KfW funding often also requires that an energy efficiency expert is involved in the creation of an energy concept. For example, homeowners and local authorities receive grants from the KfW (construction supervision grant) if an energy consultant is involved in the planning and construction supervision. Go to the various funding opportunities offered by KfW Building renovation for improved safety, fire protection, and accessibility The primary aim of building renovations is of course to implement energy-saving measures – and because of the many forms of subsidies available. However, a change of use may also be a reason for a building renovation. This often leaves the owners with other issues to make decisions about. For example, if the building no longer satisfies modern safety and fire protection standards when being converted into a children’s day nursery. Or if modern usage calls for a different floor plan. For handicapped accessible living and working, Access for all can also be the goal of modernisation. KfW funding allows owners to also redesign their building at the same time as making it more energy efficient. This means that even an old building can be converted into a Smart Building . GEZE provides support during renovation work GEZE can help to develop and implement new concepts for energy-saving ventilation technology and for fire protection and access for all, not only in new construction projects, but also in existing buildings. Various GEZE products can effectively help with energy saving, including indoor climate control via automated windows, door closers, and through intelligent building networks. GEZE door solutions offer barrier-free access, access convenience, escape route safety and energy efficiency . Renovation of existing buildings GEZE solutions aren’t just used in new buildings.

Register for the DGNB newsletter More on green buildings Planning Installation Services Planning Installation Services Specific suggestions for building automation and façade renovation Planning is paramount when carrying out building renovations. Ideas and concrete suggestions for building automation and intelligent technical solutions for the façade should be developed as early in the process as possible: Implementation of a building management system (PSIM) for the centralised control and monitoring of heating, window ventilation, door systems and lighting. Installation of presence detectors and motion sensors to automatically adjust the air conditioning in rooms when they are not in use. Integration of weather stations to enable automatic adjustment of heating, night-time cooling and sun shading based on current weather conditions. Use of building data analysis and optimisation algorithms to analyse energy consumption in building operations and identify potential savings. Improving thermal insulation, for example by replacing old windows and doors with energy-efficient models with thermally separated, thermally insulated door and window profiles. Easy installation Many GEZE products are used in renovations as they can often be installed easily. Automatic swing door systems are, for example, characterised by a simple assembly process and they can also be retrofitted. It’s a simple and flexible way to stay ahead of the frequently updated DIN standards and technological regulations that have to be adhered to during renovations. More on our YouTube playlist, including installation videos Retro-fitting and updating made easy Generally speaking, the expected lifetime and useful life of building technology has always been shorter than that of the building itself. Technical systems need to be replaced from time to time. And building technology requirements, building safety in particular, also change as a result of modifications in legislation, for example DIN 18650.

Renovating a protected historical building: Mannheim Palace

… renovation of Mannheim Palace was to implement modern fire protection and accessibility standards in the building, while achieving better energy efficiency. Gessert chose to work with door systems from GEZE, which impressed the installation company not only on a technical level, but also for their user-friendly design. © Nico Walke / GEZE GmbH Renovating a protected historical building: Mannheim Palace Building renovations under historical preservation requirements are a demanding task that requires both technical expertise and a high degree of sensitivity to the historical nature of the project. The manufacturer Gassert was commissioned with the task of modernising the doors of Mannheim Palace – an important baroque building and cultural monument – and reports on why products from GEZE are the right choice for this project. Mannheim Baroque Palace – a cultural monument Mannheim Palace has a storied history: construction of the Baroque residence according to plans by Jean Clemens Froimon began in 1720 and ended in 1760. For many years, the palace served as home to the electors of the Palatinate region; it was converted into a palace museum in 1926 after the end of the monarchy. The palace was almost completely destroyed during the Second World War, and for many years rebuilding seemed impossible. However, the palace was rebuilt between 1957 and 1964. Since that time, this magnificent edifice has been used by the University of Mannheim and as the university library. Now, as part of a building renovation in line with historical preservation requirements, the entire area between the auditorium, connecting building and art tower has been renovated. The project began in 2016. The goals of the building renovation were to improve fire protection, accessibility, and energy efficiency. For Gessert, the focus of the project was on meeting current fire protection and accessibility requirements, which are particularly high in a public building like a university. Energy efficiency was also to be improved. As it had in many previous project, Gessert used high-performing products from GEZE for the doors. These not only meet all applicable statutory requirements, but are also simple to assemble and install. These advantages are essential especially in a complex and prestigious project like Mannheim Palace – and ultimately save time and costs as well. What were the biggest challenges related to the building renovation? Key challenges during the rebuilding of the historically preserved Mannheim Palace included: Historical preservation and fire protection: The door systems needed to meet strict historical preservation requirements, while at the same time fulfilling fire protection regulations. Accessibility: For the university as a public institution, ensuring accessibility for all users in accordance with DIN 18040-1 was a key concern. Safe escape routes: Escape and rescue routes in public buildings must be accessible to persons with disabilities. An impressive team: GASSERT GmbH and GEZE GmbH GASSERT GmbH , an established specialist manufacturer of doors and windows, was responsible for installing accessible emergency exits. Since the 1960s, the company has developed from a classic steel construction firm to work with highly specialised fire protection solutions and door automation. This makes GASSERT GmbH a competent partner for challenging construction projects – and for GEZE, which delivers the right products for this speciality area. The Gassert/GEZE team has already completed a range of projects together. Simple installation, high quality and outstanding service have impressed the installation company time and again. Thus far, Gassert's collaboration with GEZE has been positive in all of the projects the team has completed. GEZE offers not only the right products to meet all requirements, but excellent service as well. The availability of contact persons and quick support with questions make the company a competent and reliable partner for us, including in future projects. Mr Arifi, Automation and Maintenance Project Manager, GASSERT GmbH So it's no wonder that GASSERT GmbH decided to use GEZE products for the building renovation of Mannheim Palace - based on many years of trusting cooperation and the numerous advantages that these solutions offer. The decisive factors for Mannheim Palace were, above all: Technical adaptability: GEZE door systems are not only very narrow, but also enable custom colour designs that meet historical preservation requirements. Safety and functionality: IQ motor locks and panic locks have been integrated into the GEZE door systems, which fulfil high safety standards and meet the requirements for emergency exit safety . Mr Arifi from GASSERT GmbH, who was responsible for the assembly and acceptance of the door systems, also emphasised that the intuitive handling of the products, including the user-friendly cable routing, made installation much easier. For fire protection and access for all: GEZE Slimdrive EMD-F and TS 5000 R-ISM door systems Slimdrive EMD-F/R-IS and GC 342 laser scanner on a 2-leaf door at the University Schloss Mannheim © Nico Walke / GEZE GmbH Many basic functions of a door closer can be individually adjusted. © GEZE GmbH The particularly narrow Slimdrive EMD-F swing door drive was used for single-leaf doors, while the TS 5000 R-ISM was used for double-leaf doors: The system consists of two door closers, the TS 5000 R-ISM and the HM overhead door closer system with guide rail. The door system has a closing sequence control that ensures that the active leaf remains in the waiting position until the passive leaf is completely closed. This is particularly practical in a university building such as Mannheim Palace, where slamming doors would be very disruptive: An integrated hydraulic back check ensures that doors that are thrown open wide are gently slowed down, while the hydraulic latching action accelerates the door just before it reaches the closed position so that it closes quietly but securely. The system also includes an integrated smoke switch control centre that sends a signal in the event of a fire, causing the door to close automatically. The smoke switch is equipped with a contamination indicator and enables adaptation of the alarm threshold to ensure functionality at all times. Furthermore, additional smoke detectors can be connected to further increase fire safety. Mr Arifi also points out the user-friendliness of GEZE door systems: "The closing speed can be easily customised. Particularly practical: all functions can be adjusted from the front and a closing force display makes it easy to check whether the setting is correct”. Learn more about setting door closers correctly GEZE systems are designed to be very intuitive, which makes assembly and later use easier for everyone involved. I would rate the user-friendliness and the installation system of GEZE products a … out of 10! Mr Arifi, Automation and Maintenance Project Manager, GASSERT GmbH Maximum safety in escape and rescue routes thanks to panic locks TS 5000 R-ISM door closer on a 2-leaf door at the University of Mannheim © Nico Walke / GEZE GmbH The IQ lock AUT self-locking panic lock was chosen for 2-leaf doors because it offers a comprehensive solution to the challenges of safety and user-friendliness, especially for full panic doors in escape and rescue routes . Here are the main advantages that led the company to choose this option: Efficiency and speed thanks to motor-driven unlocking: The door can be unlocked in less than three seconds, which is crucial in an emergency. The divided cross latch prevents the bolt from jamming even under preload, which is particularly important in high-traffic areas. This ensures that people in the building can be evacuated quickly and safely. User safety thanks to full panic function: Unlocking the active leaf by operating the passive leaf enables users to act quickly and intuitively in an emergency, ensuring open escape and rescue routes. Safety and reliability thanks to mechanical self-locking: This function ensures that the bolt automatically returns to the locked position. This increases safety and minimises the risk of unauthorised access, as the door is always correctly locked – even when no one is present. Integrated feedback contacts enable complete monitoring of the door, which is important for security protocols. As a result, the self-locking IQ lock AUT panic lock ensures that the door complies with the necessary security standards in accordance with insurance requirements, which is essential for many public institutions such as a university. Compact dimensions and flexible installation: IQ lock EL panic locks The IQ lock EL electromechanical swing door lock was used on single-leaf doors with swing door drives. Thanks to the panic function, even locked emergency exits can be opened in the direction of escape at any time. With an opening time of less than one second, rapid evacuation is possible in an emergency. The divided cross latch prevents the bolt from jamming, even when pressure is applied to the door. This is particularly advantageous in high-traffic areas. In normal operation, the automatic self-locking feature ensures that the door is always correctly locked, which significantly increases security. This combination of safety, functionality and user-friendliness make the panic lock the ideal choice for modern security solutions in public and commercial facilities, where both safety and a quick response in case of an emergency are of paramount importance. Mr Arifi also points out the simple installation and compact design: "With a small rear backset and reduced lock case dimensions, installation in various door frames is simple, which significantly increases flexibility in planning and implementation for us as fabricators." "What we particularly appreciate in our long-standing cooperation with GEZE is the reliable support: GEZE's service hotline offers immediate support and competent contacts who are always available. The commissioning and acceptance training courses offered by GEZE are also always well structured and offer both theoretical basic information on relevant regulations and practical units that facilitate the installation process.

Building renovation in historically preserved buildings: the Betonhaus Poznań

… Renovating the historic Betonhaus Poznań was an ambitious project. Customised solutions ensure structural stability where a tall concrete wall was replaced with a glass sliding door system. © Fotografia Maciej Lulko / GEZE Polska Impressive renovation, combined with historical preservation: the Betonhaus Poznań At the historic Betonhaus in the Polish city of Poznań, a very large concrete wall needed to be replaced with an open glass sliding door system to give the building more transparency and openness. GEZE was the only company willing to take on this exciting project and ensured its successful completion with customised special solutions and services. Between history and modernity: conversion of a historic building Cafés, restaurants and galleries: thanks to its conversion and building renovation, the Betonhaus, a listed building has become a popular meeting place. © Fotografia Maciej Lulko / GEZE Polska The purpose of extensive building renovation and conversion work at the historic and neglected Betonhaus in Poznań, Poland, was to give the building a new lease on life and a new functional purpose. The former exhibition pavilion was now to serve as a meeting place with restaurants, cafés, an art gallery, a hotel and offices. One key purpose of the project was to open up the Betonhaus by creating a terrace facing the surrounding Wilson Park and to establish a stronger connection to the public space. This required significant alterations to the building, however its original character needed to be preserved: Challenging plans: Will the listed building be able to meet structural stability standards? The most challenging plan was to replace a very high, solid concrete exterior wall with a modern glass sliding door system while retaining the original architectural columns that characterise the building's exterior appearance. Three critical considerations were in focus here: Can a sliding door system cope with the height and static load? Can a solution be found that is sufficiently wind-resistant? How stable is the existing ceiling construction? Building renovation and conversion in historical preserved buildings As the project is subject to historical preservation regulations, the planning and implementation of all construction work involved special requirements. The original character of the architecture had to be preserved despite the conversion of the listed building , even though significant structural changes had to be made in order to implement the ambitious plans. Visionary and competent: GEZE as a project partner GEZE was the only company on the Polish market that was prepared to take on this highly complex and unique challenge. GEZE's ability to deliver a customised solution was the decisive factor. In addition, thanks to its many years of expertise, GEZE was able to provide support during the planning phase of the project with specialist knowledge on sustainable modernisation and building renovation , and will continue to be available after the project is completed with services such as maintenance and support. LEARN MORE ABOUT GEZE SERVICES Customised solution without compromise: GEZE MSW glass sliding wall system The large glass elements of the customised sliding door system can be opened or closed depending on the weather. © Fotografia Maciej Lulko / GEZE Polska One of GEZE’s key USPs was use of the movable glass partition wall system MSW with specially developed running gears, which ensured safe and reliable operation despite the unusual height and structural requirements. The GEZE manual sliding wall system uniquely combines flexibility, aesthetic integration and functionality – all essential factors in transforming the historic industrial building into a modern, multifunctional space. The flexibility of the solution was decisive: the product can be adapted precisely to almost any architectural space – including the special conditions of the historic Betonhaus. This ability to seamlessly integrate the system into a non-standardised structure without compromising on functionality or design was key to the customer's decision to work with GEZE, and continues to be a strong selling point for future projects. Currently, the Petit Paris restaurant is located in this area of the Betonhaus. The restaurant not only benefits from the inviting character and charming view of the park provided by the open façade, but can also use the terrace regardless of the weather and season. Daria Kuttene, owner of Petit Paris, highlights the high functionality, flexibility and seamless integration of the GEZE MSW glass sliding wall system as key factors in creating an open, inviting space that enhances the restaurant's atmosphere all year round. Thanks to the glass wall system, we can easily connect the interior of the restaurant to the terrace. Guests feel like they are sitting right in the middle of the park – whatever the weather. Daria Kuttene, owner of Petit Paris The advantages of the MSW movable glass partition wall Architectural adaptability: The manual sliding wall system creates open, modular spaces that reflect the architectural vision of the Betonhaus – the building’s industrial character is retained, yet it remains flexible for modern uses (e.g. retail, hospitality or cultural functions). Maximum transparency with minimal intervention: Frameless, fully glazed sliding panels preserve the visual integrity of the original concrete structure while providing a modern, open feel and natural light. Flexible room design: The manual sliding wall system allows the room to be easily reconfigured according to the desired usage: it can be closed to create intimate spaces or opened completely to connect interior areas with exterior areas or connect building sections. Efficient manual operation: Simple operation thanks to intelligent guidance systems and smooth opening/closing mechanisms allows the room to be reconfigured frequently without technical barriers for users. Customisable storage options: Storage recesses integrated into to the building structure provide a clean and discreet way to store the infill panels when the system is open – essential to maintaining the minimalist aesthetics of the revitalised space. LEARN MORE ABOUT ROOM PARTITIONING GEZE MSW: Customised sliding door system for modern, open and flexible room design The guide rails of the system allow for safe operation of the manual sliding wall system. © Fotografia Maciej Lulko / GEZE Polska Special solutions were implemented for the Betonhaus to ensure both functionality and aesthetics: three of the infill panels in the manual sliding wall system were designed to serve as entrance doors. When the partition wall system is opened or closed, these integrated door assemblies move together with the rest of the system, maintaining a seamless appearance while providing easy and functional access to the building. This solution was specially tailored to the client's desire for optimum usability without compromising the architectural coherence of the façade. Challenging statics: powerful special solutions for the Betonhaus As the building was very old and no detailed support documentation was available, a customised static reinforcement system was developed to ensure sufficient load-bearing capacity. In close cooperation with a structural engineer from SQT Inżynieria w Budownictwie and an architect from JEMS Architekci, a reinforced steel substructure was designed to reinforce the existing ceiling. This customised solution was essential to ensure the structural integrity of the building, particularly given the unknown load-bearing capacity of the original structure. The reinforcement enabled the new manual sliding wall system to be installed securely while preserving the historic character of the building. The challenge of historical preservation: between safety and aesthetics Throughout the project, ongoing consultation with the conservation officer was essential. Their approval was required for each phase of the reconstruction to ensure that the historical value of the building was preserved while incorporating modern elements such as accessibility and fire protection . Another challenge was the presence of historical architectural elements that could not be moved or altered, such as the columns. To get around this, additional side guide rails had to be designed, which made it possible to install the sliding wall system without touching or damaging these protected parts of the building. One reason why the solution was accepted by the conservation officer was that, despite its impressive size, the GEZE MSW system is visually unobtrusive. It blends harmoniously into the historic architecture and preserves the original aesthetics of the room. Thanks to this customised combination of intelligent technology and subtle design, the room has been modernised in a way that meets the requirements of the historic preservation authorities, while also satisfying structural and aesthetic requirements. Betonhaus Poznań The Betonhaus, made of reinforced concrete, was built in 1910 over a six month period as an exhibition pavilion. It opened in May 1911 as part of the East German Exhibition for Industry, Crafts and Agriculture. It was originally used as a "hunting lodge" where imperial trophies were displayed. Over time, the hall has had various purposes, including housing university departments and serving as a music pavilion. The house is particularly impressive due to its ornately decorated barrel vault. GEZE Services at a glance Planning Process Implementation Installation Product trainings Acceptance Maintenance Planning Process Implementation Installation Product trainings Acceptance Maintenance GEZE provided the client with comprehensive support during the planning phase, supplying all the necessary CAD drawings for the manual sliding wall system. These technical drawings formed an important basis for the structural engineer and architects’ work, and enabled the partition wall system to be integrated precisely into the building design. Thanks to GEZE's detailed and project-specific documentation, the planning team was able to ensure optimal coordination between the architectural concept, the structural requirements and the functional expectations. LEARN MORE ABOUT PLANNING GEZE actively supported all parties involved in the project through close cooperation on site and via remote access. GEZE specialists on site and in the office worked hand in hand with architects, engineers and installation teams to ensure smooth communication, efficient problem solving and seamless integration of the manual sliding wall system at every stage. This proactive approach helped to keep the schedule on track, resolve technical challenges and align system implementation with the overall vision of the project. GEZE supported the implementation process by working closely with the contractor throughout the installation and ensuring correct alignment with system specifications and functional requirements. Installation of the manual sliding wall system was handled by an external contractor. However, GEZE provided technical support throughout the process to ensure proper assembly and configuration. GEZE conducted on-site training for the plant's operating personnel. As the manual sliding wall system is a custom-made product, selected personnel were instructed in how to open and close the system correctly and safely. Only trained persons are authorised to operate the system. LEARN MORE ABOUT GEZE TRAINING GEZE supported the acceptance process by ensuring that the system was properly configured and functional prior to handover. There were no complaints or problems from the installation company, confirming the quality and conformity of the system. GEZE offers a system maintenance service and is available for ongoing support as required to ensure the long-term reliability and performance of the solution.

State-of-the-art door systems for the renovated Sihlpost - GEZE

… renovated Sihlpost Entrance area with automatic sliding doors in the entrance area of the Sihlpost, exterior view. © Christian Moeller / GEZE GmbH Case studies GEZE door systems: A fresh interior for a Zurich landmark Zürich's main post office, the Sihlpost, is considered an historical landmark in the city. GEZE was involved in the complete and sympathetic renovation of this listed building by providing multifunctional door systems and emergency exit doors to support safe and comfortable use of the building. Automatic sliding doors in emergency exit design The side façades also offer emergency exit doors with barrier-free ease of access. © Lorenz Frey / GEZE GmbH Built in the ‘New Building’ (Neues Bauen) style, the 123-metre long square building, with its clock tower visible from afar, was the most modern post office in the world when it was completed in 1930. The Swiss Federal Railway (SBB), which owns the building, has invested 45 million francs in comprehensive renovation of the Sihlpost. The listed building was upgraded to the latest standards and its interior fully renovated under the direction of Max Dudler Architekten AG. Today, the Sihlpost building offers a fresh exterior façade and serves not only as a post office building, but also as a modern urban centre for retail, restaurants, education, and business. The three large eye-catching glass portals on the impressive building front serve as entrances to the main hall, and to the separate locker area. The double leaf automatic sliding doors, at roughly 300 cm tall and 320 cm wide, offer generous and barrier-free ease of access. Fine-framed and visually discreet, the heavy door leaves move powerfully and quietly. The GEZE Slimdrive SL FR drive systems for escape and rescue route doors ensure safe escape routes in the event of danger. Automatic door systems with intelligent control technology Maximum door opening with limited space: quadruple-leaf automatic telescopic door. © Lorenz Frey / GEZE GmbH Intelligent control technology is concealed inside the reliable Slimdrive drive units, which are just … cm tall. The doors’ hold-open time adapts automatically to the frequency of use. All motion parameters, such as acceleration, hold-open time and opening and closing speeds can be set individually. Offering a forward-thinking design, Slimdrive door systems can also be integrated into the building management system so that door functions can be monitored or adapted from a central location. A telescopic door for maximum opening widths The automatic sliding door in the entrance area to the Piu serves as an emergency exit door. © Lorenz Frey / GEZE GmbH The new design means that more people use the Sihlpost building than ever before. During the renovation, direct access was created to the KV Zürich Business School building through the newly renamed Sihlpostgasse (Sihlpost Street). GEZE installed a quadruple-leaf automatic telescopic door with specially designed Slimdrive SLT drive systems in an escape route version in the limited space of the building opening. It can reach a maximum opening width of 250 cm if necessary, allowing the door leaf to be ‘parked’ open with ease. Fanlights above the telescopic door allow for optimal use of daylight. Emergency exit doors: Safety and efficiency in the service sector Emergency exit for ‘easy access’ in the event of a fire. © Lorenz Frey / GEZE GmbH Builders put their faith in the proven quality of GEZE fire protection and fire closer doors in the building's restaurant areas too. Fully automatic sliding doors with fire resistance class EI30 create a safe barrier against fire, smoke, and heat in the basement of the traditional vegetarian restaurant Hiltl . A powerful GEZE Powerdrive PL drive moves the large and heavy metal sliding doors to the food storage area. A double leaf metal sliding door with viewing panes in the passage between the kitchen and service area handles the constant movement of staff in and out quickly, quietly, and with barrier-free access - thanks to the Slimdrive SL NT drive.

Wireless fire door holders

… Renovating listed buildings presents challenges, such as laying cables for fire protection solutions. GEZE’s wireless fire door holders offer state-of-the-art solutions. Case Studies GEZE wireless fire door holders used in building renovation Construction involving historical buildings usually also means complex cable-laying for fire protection solutions, such as ceiling-mounted smoke detectors. Our unique, tried-and-tested FA GC 170 wireless extension for fire door holders, which has already been successfully used in the renovation and modernisation of the listed head office of the metal industry trade association in Dortmund, is the perfect wireless alternative. The advantages of the FA GC 170 wireless extension for fire door holders: no separate cable laying, no knocking-through of walls simple retro-fitting construction effort and costs are avoided ideal solution for listed buildings and/or if structural changes are not viable/not desired Planning certainty: change of fire protection concepts and change in use of doors flexible system design for particular structural conditions: tested in accordance with the European DIN EN 54 25 standard for fire alarm systems Wireless extension system with general construction technique permit (DIBt) for GEZE hold-open systems low maintenance: 5-year battery life cable runs to ceiling-mounted detectors are not necessary Modernisation of the listed Gründerzeit villa The headquarters of the metal industry trade association in Dortmund are located in a listed classical villa. The work done in the brick building, reminiscent of the ‘the good old days’, is highly relevant, and tackles the top important topics facing of our modern working environment. The building was constructed in 1894 during a period of rapid industrial expansion in Germany. With its ornate façade, arched entrance with an oriel window above it and its high ceilings, it was the first ‘industrialist’s villa’ to be built in the affluent Prinz-Friedrich-Karl-Strasse district which was established in around 1900. Today, this city palace is a listed building – and as a result presents challenges in terms of maintenance, renovation and modernisation work. Improved convenience thanks to new door systems and optimal fire protection The wireless extension kit FA GC 170, the ideal solution for listed buildings. © Annika Feuss / GEZE GmbH The trade association’s ‘residence’ was no longer able to meet modern technology and usage demands. The renovation and modernisation project breathed fresh life into the some 20 rooms of this three-storey office building. GEZE door technology makes it even more “liveable”, as it offers users and visitors modern door convenience and optimal safety, in accordance with the necessary fire protection. New fire protection concept with automatic fire protection doors Because the building was to be used for a new purpose, the renovation called for a rethink of the fire protection concept for rescue routes and fire protection closers. To create the desired ease of access and an open atmosphere, the new fire protection doors had to stay open using hold-open devices during daytime operation – but the doors obviously had to close automatically in an emergency. All this is possible thanks to fire door holders: the automatic door hold-open devices hold fire protection closer doors open until they are either closed manually or – in the event of a fire – are safely closed by releasing the smoke switch. Greater safety and ease of access with GEZE door push bars and hold-open mechanisms Reliable fire protection and accessibility for fire closures with automatic and manual swing door systems: open and accessible during daily operation, thanks to automatic door hold-open devices and push bars automatic closure of fire and smoke protection doors in the event of a fire Restoring historical buildings presents challenges The wireless extension kit FA GC 170 allows flexible system design for particular structural conditions. © Annika Feuss / GEZE GmbH The renovation soon raised the question: how best to meet the special demands placed on fire protection doors with fire door holders in this listed historic and architectural gem? Because of the high ceilings and the space between the lintel and the ceiling far exceeding one metre, additional ceiling-mounted smoke detectors were needed on both sides of the door. Additional cable guides in the ceiling are normally unavoidable in this scenario. Building operators, door constructors and planners thus faced the challenge of leaving historic ceilings – some of which have beams – untouched. An example of the installation: no separate cable laying, no knocking-through of walls. © GEZE GmbH The solution: a wireless extension for fire door holders The GEZE FA GC 170 wireless extension has the great advantage of not needing any additional cables. Cable connections between lintel-mounted and ceiling-mounted detectors and/or manual trigger switches are unnecessary, making installation, retrofitting and reconstruction much easier. Easy wireless extension installation for fire door holders GEZE Service found it easy to attach the additional fire detectors needed for fire protection to the ceiling. All components of the FA GC 170 wireless extension for fire door holders were connected to the existing door closer system via a wireless module. FA GC 170 is therefore an optimal retrofit solution: ceiling-mounted smoke detectors and trigger mechanisms can also be connected without cables to the wireless module on the lintel-mounted detectors of other fire protection closers in the building – with no expensive cable-laying construction work needed. Go to the wireless kit FA GC 170 Installation of the fire protection doors could not have been simpler or quicker. They also needed to be accessible, and kept open if necessary. The GEZE wireless fire door holders meant that no walls had to be knocked through for cables to the additional ceiling-mounted smoke detectors which the high ceilings called for. We were able to leave the structure of the listed building intact, use a secure and approved system, and save effort and costs as well. Gerhard Kämper, in-house technician and renovation co-organiser DIN-tested wireless extensions with general construction technique permit FA GC 170 wireless extension for fire door holders We offer a unique solution for fire door holders with wireless components, tested to the European DIN EN 54 25 standard for fire alarm systems. Thanks to the innovative GEZE wireless extension with a general construction technique permit (DIBt) for GEZE fire door holders, alternative extension solutions and extension solutions which did not meet guidelines and approvals could be avoided, as well as the associated project-related, costly and time-consuming approval and permit processes.

Window solutions for modernisation under historical preservation requirements

… renovation of the tower blocks in Hamburg's Grindel district shows how modern window solutions respect historical preservation requirements, increase user comfort and improve energy efficiency. © Jürgen Biniasch / GEZE GmbH Sustainability building renovation under historical preservation requirements: double casement windows as a customised window solution for the Grindel tower blocks After an extensive building renovation, the listed high-rise building at Oberstrasse 14b in Hamburg's Grindel district is now ready for a long service life as a modern commercial property. GEZE window drives in a double casement window with an integrated shading system now provide fresh air and user comfort. A mammoth project: the building renovation of the Grindel tower blocks One central aspect of the building renovation of the high-rise building at Oberstrasse 14b was updating the windows and heating surfaces in the building. At the same time, sun protection and ventilation comfort for building users needed to be improved, so that the listed building could be used in a contemporary way with computer workstations. However, historical preservation requirements for the building had to be taken into account, which demanded creative solutions. What are the key considerations for building renovations under historical preservation requirements? Sören Eilers, Specification Sales Manager at GEZE, supported the building renovation with his expertise in developing window solutions for modern living comfort. © Jürgen Biniasch / GEZE GmbH The following requirements must be observed for windows during building renovations of listed buildings such as the Grindel tower blocks: Historic window shapes and materials must be preserved. Unavoidable changes, colouring and surface treatments should correspond to the historical appearance and not impair the original design. Windows may only be replaced if they are irreparable. Repairs and restorations should be prioritised. Energy aspects such as sufficient insulation must be harmonised with the requirements of historical preservation. Important note: The approval of the monument protection authority is required for all changes to listed windows. Because of this, it is a good idea to get in contact with the relevant monument protection authority at an early stage to clarify specific requirements and guidelines. LEARN MORE ABOUT BUILDING RENOVATION The renovation of this historic building required not only technical expertise, but also careful coordination – so that all project partners can work closely together. The client's aim was to integrate innovative window solutions that preserve the charm of the tower blocks, while offering modern living comfort. Sören Eilers, Specification Sales Manager / Deputy Branch Officer at GEZE Nord Double casement windows as an innovative window solution that complies with historical preservation requirements Sören Eilers from GEZE and architect Martin Muus worked closely with the window and glass manufacturer during the planning process. © Jürgen Biniasch / GEZE GmbH Replacing the windows was unavoidable in order to improve the shading and ventilation concept and at the same time improve thermal insulation in summer and winter, sound proofing and user and working comfort. Under historical preservation requirements, the external appearance could not be changed, not even by sun protection. The idea: One of the oldest and most proven window types, the casement window, was reinterpreted by the architects Dipl. Ing. Muus and Dipl. Ing. Wilde, who were in charge of the project. To solve these challenges, the architects worked closely with window manufacturer Sehlmann Fensterbau GmbH, glass manufacturer Semcoglas Holding GmbH and the window drive specialists from EMT and GEZE at an early stage of the project – true to the motto "Achieving more together". Commitment and open communication with everyone involved enabled us to recognise challenges at an early stage and develop solutions together. This close and very cooperative partnership helped ensure the project went smoothly. Architects Dipl.-Ing. Muus and Dipl.-Ing. Wilde, MUUS & WILDE Architektenpartnerschaft Hamburg The solution: modern double casement windows that comply with historical preservation requirements Dennis Bredahl from Semcoglas Holding GmbH optimised the thermal and sound proofing of the double casement windows with special solar control and thermal insulation glazing. © Jürgen Biniasch / GEZE GmbH A double casement window consists of two window elements arranged one behind the other and mounted on a common frame. The advantage of this historic window concept: The air space between the two window elements serves as thermal insulation and sound proofing, as the staggered opening of the windows means that sound has to pass through the space between them and is thus significantly attenuated once again, even during ventilation. Our modern casement window solution uses high-quality solar control glass on the outside and thermal insulation glass on the inside, which significantly improves the insulation value and sound proofing – also increasing user comfort in the buildings. Thanks to the double glazing, double casement windows already offer much higher thermal and sound proofing compared to conventional windows. These properties were significantly improved by the use of high-quality solar control glazing and thermal insulation glass as so-called neutral glass and a special coating (Semco Klimaglas). Dennis Bredahl, Semcoglas Holding GmbH Window manufacturers Jan and Lasse Sehlmann implemented customised solutions that combine historical preservation and user requirements. © Jürgen Biniasch / GEZE GmbH Pleasant indoor climate thanks to integrated shading The new double casement windows are equipped with an integrated shading system. This consists of automatic composite blinds with 35 mm wide slats that run between the two window frames. This solution makes it possible to keep the rooms cool during the day, while at the same time ensuring natural ventilation through the outer window. The blinds can be operated independently for added convenience. This reduces costs for air conditioners and the offices are naturally ventilated. Modern casement window at the Grindel tower blocks in Hamburg. © Jürgen Biniasch / GEZE GmbH Safety and ease of use thanks to modern window drives For the outer window leaves, GEZE Slimchain drives were installed as a system solution in combination with the Power lock locking drive , which enables simple operation via push buttons in the room. The inner leaves of the double casement windows can still be opened manually. The Power lock locking drive ensures that a reliable lock is guaranteed, especially on the higher storeys, and even under heavy wind loads. As only the outer windows are motorised, no additional protection is required for power-operated windows in accordance with the Machinery Directive 2006/42/EC. The opening drives were integrated into the window frame in a concealed location, and the supply lines were routed in the construction joint. A unique feature: With their very slim and discreet appearance, the Slimchain window drives integrate perfectly into the structure – so that strict historical protection requirements are met. This means the well-insulated double casement windows with integrated shade control are a modern, comfortable and energy-efficient solution that simultaneously respects the architectural character of the building and complies with the strict historical preservation requirements. The technical expertise and the rapid involvement of all parties in the planning process enabled us to develop customised solutions that meet both high historical preservation requirements and the needs of building users. Jan and Lasse Sehlmann, window fitters at Sehlmann Fensterbau GmbH Achieving our goal together: successful project planning and coordination GEZE was already in close contact with all project participants in the early planning phases, which enabled smooth discussions and effective collaboration. This early involvement of all parties made it possible to identify potential challenges at an early stage and develop solutions together. In addition, GEZE supported project coordination through continuous cooperation with the partner company EMT. Contact with the architect and building services was also maintained during the implementation phase. This ongoing collaboration ensured that all aspects of the project were seamlessly integrated and that the implementation went smoothly. Modern history: the listed Grindel tower blocks The Grindel tower blocks in Hamburg's Eimsbüttel district were the first residential tower blocks built in Germany after 1945. They were highly modern and comfortable flats when they were built in the post-war period, and remain so today – with central heating, hot and cold running water and lifts. In addition, the flats are bright and flooded with light thanks to their orientation and windows, while remaining pleasantly shaded in summer. Today, the ensemble of twelve high-rise buildings and a park is historically preserved. A tip for visitors to Hamburg: in the centre of the Grindel tower blocks is the Eimsbüttel district office, which has become a real tourist attraction with its historic paternoster lift The Grindel tower blocks in Hamburg's Eimsbüttel district were the first residential tower blocks built in Germany after 1945. © Jürgen Biniasch / GEZE GmbH These consist of two window elements arranged one behind the other and mounted on a common frame. © Jürgen Biniasch / GEZE GmbH Double casement windows were used as a customised window solution for the Grindel tower blocks. © Jürgen Biniasch / GEZE GmbH Comprehensive support throughout the entire project life cycle Our experts support you throughout the entire project life cycle – from planning and project coordination to the certified assembly and initial acceptance of GEZE systems and regular maintenance, through to retrofitting and dismantling.

Modernisation and new construction at Stuttgart Hospital

… renovation during ongoing operations GEZE is supporting the modernisation of the Katharinenhospital, part of Klinikum Stuttgart, with smart technical building systems and enabling efficient building operation thanks to intelligent door and window technology. © Jürgen Pollak / GEZE GmbH Efficient hospital modernisation through intelligent door technology and technical building systems Completing building renovations during ongoing hospital operations is one of the biggest challenges in the construction industry. At the Katharinenhospital, part of Klinikum Stuttgart, GEZE successfully helped design a new building as part of a comprehensive modernisation project: using modern window, door and automation solutions in the hospital improves efficiency, security and hygiene in everyday use and for the long-term. New construction of the Katharinenhospital, part of Klinikum Stuttgart GEZE door systems make access barrier-free for visitors, patients and hospital staff at the Katharinenhospital, part of Klinikum Stuttgart. © lake.office / GEZE GmbH In a hospital, doors must meet a wide range of requirements for accessibility, emergency exit protection, and hygiene. © Jürgen Pollak / GEZE GmbH Operators, architects, contractors: when it comes to renovating a hospital, everyone involved faces a wide range of challenges. No wonder, then, that hospital renovations are among the most complex construction projects there are. On the one hand, operators and planners are under enormous budgetary pressure, as financing is often determined by public funds and strict economic efficiency requirements. The time factor also plays a decisive role: delays drive up costs and put a strain on already tightly scheduled hospital routines. Added to this is the special responsibility for patient safety – medical procedures must not be disrupted; outages and interruptions are simply not an option. Because of this, building renovations in a hospital can only be successful if they are professionally planned and smoothly implemented during ongoing operations – efficiently, reliably and with no negative impacts for patients and staff. The Katharinenhospital at Klinikum Stuttgart has faced, and continues to face these challenges: the hospital is ageing and is being rebuilt in stages to provide more space for care and research. As an expert in building automation, GEZE supported the construction of Building F, which was rebuilt as part of the building renovation. Similar to the renovation of existing buildings, the task here was to overcome the enormous challenges posed by construction projects in the health care sector . Challenges posed by construction projects in the health care sector High cost pressure due to limited public budgets Increasing requirements for hygiene, security and accessibility Need to optimise the use of personnel Energy efficiency as a key requirement for sustainability GEZE health care solutions Born from experience: New construction at the Katharinenhospital as part of the overall renovation A successful example of modern hospital architecture: Klinikum Stuttgart – Katharinenhospital © Jürgen Pollak / GEZE GmbH At Klinikum Stuttgart – Katharinenhospital, GEZE door systems ensure barrier-free accessibility, emergency exit protection and hygiene. © Jürgen Pollak / GEZE GmbH In addition to various renovations of existing buildings, new buildings are also part of the modernisation concept for the Katharinenhospital. Building F is part of the new construction and was built on an area of approximately 40,000 square metres. Since early 2022, the building on Kriegsbergstraße in the heart of Stuttgart city centre has served as the first point of contact for all patients at Katharinenhospital. The new building houses the radiology clinics, internal medicine departments and wards with around 250 beds. At its heart lies the large interdisciplinary intensive care unit with over 60 beds meeting modern hygiene standards. Here, specialist departments such as internal medicine, neurology, anaesthesiology and surgery work closely together in a state-of-the-art unit. A haematological-oncological transplant ward and one of the largest endoscopy departments in southern Germany were also established. The construction of the new building wing presented a particular challenge: doors had to be planned during the construction phase, even though the functions of some large areas were not finalised until late in the process. Because of this, the architect handled the lion's share of the planning and had to respond flexibly to new requirements. GEZE was able to provide targeted support for this process with three key solutions that are crucial for everyday hospital operations. Different hospital areas place different demands on door systems. © Jürgen Pollak / GEZE GmbH Lock solutions for secure transitions The ability to bring persons through interlocking door systems is essential in hospitals, especially at transitions to operating wings, intensive care units or clean rooms. These systems ensure that only authorised personnel are granted access, while also preventing the introduction of germs. Automated door systems in interlocking doors not only improve hygiene, but also increase efficiency by supporting staff workflows. Once integrated into building automation, access rights can be flexibly controlled, processes documented and security and hygiene seamlessly monitored. The GEZE TS 5000 R-ISM overhead door closer system with guide rail can be used to set a closing sequence control. This holds the active leaf in a waiting position until the passive leaf is closed. An integrated smoke switch control unit signals the automatic closing of the door in the event of a fire. This airlock solution thus ensures security and hygiene in sensitive areas of the hospital. SHEV air inlet systems for safety in the event of a fire Another key element is the controlled supply air for smoke and heat extraction (SHEV) systems. In the event of a fire, the SHEV control panel for smoke and heat extraction drives GEZE MBZ 300 supplies power to electrically operated window/ventilation drives. This ensures that rescue routes remain functional by systematically removing smoke and supplying fresh air. At the same time, the GEZE RWA K 600 retractable arm drive supports the smoke and heat extraction system on the door side. This not only facilitates evacuations, but also supports the work of emergency services personnel. By connecting to the building automation system , SHEV air inlet systems can be intelligently linked to fire protection and alarm systems – for maximum security and a coordinated response in an emergency. GEZE solutions play a key role in ensuring hospitals are secure, hygienic, and barrier-free. © lake.office / GEZE GmbH Barrier-free and safe: handicapped accessible access and emergency exit protection Even in the entrance area we can see how important accessibility is in everyday hospital operations. All user groups benefit from a handicapped accessible entrance, as it provides all patients, visitors and staff with equal and convenient access as well as secure escape routes – regardless of mobility restrictions. The GEZE Powerturn IS/TS swing door drive system with emergency exit protection, in combination with the RWA K 600, is the ideal solution for handicapped accessible access and emergency exit protection , as it ensures ease of use, reduces staff workloads and ensures smooth operation in high-traffic areas. Integrated into the building automation system, these entrances can also be monitored and controlled centrally, ensuring security and accessibility at all times. At GEZE, our door systems are always certified in accordance with DIN standards for barrier-free building (DIN 18040). Conclusion: Future-proof and efficient thanks to GEZE hospital solutions GEZE solutions play a key role in ensuring hospitals can be operated safely, hygienically, accessibly and efficiently. The strength of the products lies not only in their individual functions, but above all in their integration into a building automation concept, which intelligently networks all systems and supports smooth hospital operations. From the outset, our collaboration with GEZE in building automation and door and window technology has been characterised by professionalism and solution-oriented thinking. With these modern systems, we can offer our patients, visitors and staff the highest level of comfort and security. Daniela Feindor, Department Head at the New Building, Katharinenhospital, Klinikum Stuttgart What is the best way to complete hospital renovations during ongoing operations? Door systems must function smoothly during everyday use in the hospital. © lake.office / GEZE GmbH Building renovations in hospitals almost always have to be carried out while the hospital is still in operation – a complete shutdown is unthinkable. For this reason, planning and implementation of hospital modernisation projects are usually carried out in stages: individual parts of the building are renovated one after the other, while others remain in operation. This approach reduces downtime, ensures continuous patient care and minimises disruption to everyday hospital operations. For managers, this means precise scheduling, close coordination of all trades and maximum efficiency in implementation. When handling technical planning of doors, windows and building automation control systems, GEZE likes to work with architects and managers from the start of the project to discuss the best possible solutions and timelines. Solution concept for efficient hospital processes: smart building automation Our experts find the right solutions for healthcare facilities. © lake.office / GEZE GmbH Building automation should always be the overarching goal of any hospital building renovation: intelligent networking of all systems – from doors and windows to access controls and air conditioning – creates uniform control and enables optimised processes. Efficiency, hygiene, security and accessibility: building automation in everyday hospital operations Increase efficiency – reduce costs: Modern building automation networks all hospital systems. This simplifies processes, optimises workflows, reduces staff workloads and lowers energy consumption over the long-term – a tangible benefit for day-to-day operations and the budget. Enabling sustainability: Modern door automation enables the use of visionary technology and robotics, which can be used for cleaning or food delivery, for example, and improves staff efficiency. Ensuring hygiene: Automatic door systems and non-contact operating solutions minimise contact points by reducing the risk of germ transmission and improving infection control and cleanliness. Combined with intelligent ventilation technology, they support the highest hygiene standards and actively help protect against infections. At the same time, access areas can be controlled according to hygiene zones and infection control measures can be easily supported. Ensuring security : Networked access solutions allow doors to be controlled specifically for staff and patients, while at the same time securing escape routes and reliably protecting particularly sensitive areas such as operating theatres or intensive care units. To this end, the doors can be networked with access and safety systems via the building automation system. Manual interventions and personnel costs are reduced at the same time. Implementing accessibility: Intuitive operating concepts, easily accessible doors and flexible solutions for all areas of the building enable barrier-free use – for everyone. Automated door systems and intelligent window controls facilitate access for patients, visitors and staff alike. Increasing energy efficiency: Intelligent control units for doors, windows and air conditioning systems prevent energy loss, improve indoor air quality and permanently reduce operating costs. The smart technology can be optimally coordinated with heating, ventilation and air conditioner systems. In this way, the technology not only contributes to sustainability, but also helps reduce the financial burden on operators. Integration into existing structures is simple and efficient – without long downtimes. The result: greater operational efficiency, lower energy costs, increased security and noticeably better comfort for staff, patients and operators.

Modern door technology in listed building

… renovation and modernisation. In the historic town hall of La Rochelle, a French coastal city in the département of Charente-Maritime, modern GEZE door systems ensure that the heritage-protected architecture is preserved while making the town hall accessible to all. France’s oldest town hall in La Rochelle is a listed historic building The historic arcade walkway leads to the modern entrance door. © Aline Nédélec / GEZE GmbH The town hall has been on the same site since the city of La Rochelle was founded in 1298, making it one of the oldest still in use in France. It was built in the Gothic and Renaissance styles and, with its crenellated curtain wall, small corner turrets and watchtower with a ceramic statue of the French King Henry IV, is among the city’s most significant historic buildings. Public areas with automatic all-glass sliding doors. © Aline Nédélec / GEZE GmbH Renovating a listed building In 1861, the historic building was placed under heritage protection and underwent extensive renovation to restore some of the original elements and carry out necessary modifications and upgrades. La Rochelle town hall has now undergone vital renovations for a second time. This work followed a fire that spread to all roof areas in the historic part of the building, which caused the structure to collapse. Given the scale of the damage and the historic building’s cultural value, the extensive reconstruction posed considerable challenges. The most significant challenges undoubtedly lay in restoring the listed sections of the building to their original condition. At the same time, areas open to the public needed to be redesigned in line with modern standards on safety and accessibility. Under the leadership of Philippe Villeneuve, a renowned chief architect of historic monuments also responsible for the restoration of Notre-Dame, the project to reconstruct and renovate the historic town hall lasted almost six years. However, these efforts have paid off: the historic architecture now shines with new splendour and La Rochelle town hall offers outstanding convenience and accessibility to all visitors. The reception desk is behind an automatic all-glass door. © Aline Nédélec / GEZE GmbH A bright reception area thanks to automatic all-glass sliding doors. © Aline Nédélec / GEZE GmbH Automatic sliding door systems ensure accessibility Ensuring accessibility in the historic town hall was a key aim of the extensive renovation and modernisation project. The public areas are now bright and clear thanks to the automatic all-glass sliding doors installed in the foyer. The automatic doors ensure that the building is accessible to all visitors, including people with reduced mobility. Discreet design supplements historic architecture Automatic doors with GEZE Slimdrive door drive systems have been installed in the building’s foyer. With an installation height of just … centimetres, the door system blends in seamlessly with the historic architecture. One of the automatic sliding doors is behind an original door, which has been retained in the façade. This made it possible to retain the listed façade while ensuring modern access convenience within the building. Beyond the vestibule in the foyer, another automatic all-glass double sliding door leads to the reception desk.

Natural ventilation for the Lindenbüel school building in Volketswil

… renovation. Thanks to automated natural ventilation and night-time cooling, the indoor climate has improved noticeably, and the investment has also paid off in terms of energy efficiency. Sustainable school: improved indoor climate and reduced energy consumption The Lindenbüel school building in Volketswil, Switzerland, needed renovations to be more resource-efficient, sustainable and comfortable in the future. One key objective was to use natural ventilation and night-time cooling to improve the indoor climate while promoting sustainable and resource-efficient building operation. The goal was to make the building fit for the future in the face of climate change. To this end, the windows needed to be equipped with electric drives and a control system needed to be installed on site. Sustainable school renovation: Why an energy-efficient façade is essential Fanlight in the school corridor for ventilation and as a source of light. © Lorenz Frey / GEZE GmbH For economic and environmental reasons, buildings are being used for longer and longer periods of time. Legal requirements such as the Climate Protection Act and the European Green Deal are reinforcing this trend, as they drive renovation projects and set clear requirements for building energy efficiency. As a result, energy efficiency in existing buildings must be significantly improved. Automated façades in particular can deliver impressive improvements in energy efficiency, comfort and safety. This does not always require the entire façade to be replaced. Often, simply retrofitting manual windows with electric window drive can significantly improve a building's energy balance. Climate Protection Act The Climate Protection Act stipulates that Germany should become climate neutral by 2045 at the latest and that 65 per cent of greenhouse gas emissions should be reduced by 2030. Energy-efficient renovation of existing buildings, in particular, is one potential way to meet this goal. The potential savings are huge: building operations account for around 35 per cent of final energy consumption and around 30 per cent of CO2 emissions in Germany. Similar laws have been passed in many other countries in recent years. Retrofitting smart window drives can be carried out quickly and cost-effectively as part of a building renovation . Networked via the IQ box KNX , windows can be integrated directly into the building automation system and conveniently controlled via the building management system. There are many reasons to use this kind of retrofitting and automation, particularly in schools. … good reasons for natural ventilation with electric window drives via building automation In view of changing climatic conditions, schools must find ways to make their buildings usable and comfortable in order to ensure stress-free learning and teaching. One relatively straightforward solution is to use natural ventilation in the form of an energy-efficient façade. Building automation allows classrooms and common rooms to be air-conditioned more comfortably for pupils and staff – without the use of costly and energy-intensive air conditioning units. Improved indoor climate through precise control via integration into smart building systems A good indoor climate is essential for health and learning. Electric window drives enable demand-based ventilation, often controlled by timers or sensors. In combination with CO₂, humidity and temperature sensors, air quality is continuously monitored and improved in a targeted way. This ensures that fresh air reliably enters the room, stuffy air is avoided, the risk of mould is reduced and overall room hygiene is improved. In particularly busy classrooms, teachers and pupils benefit from healthy air and improved concentration – without teachers having to intervene manually. Automatic night-time cooling and response to weather events Automatically controlled night-time cooling is particularly beneficial during the summer months, when ventilation is less efficient during the day. The windows open in the early hours of the morning to cool the room to the optimum temperature, without added personnel expenses. Sensors simultaneously check that there is no danger from weather conditions such as strong wind or rain and, if necessary, close the windows. Teachers and students benefit from an optimally temperature-controlled classroom even before lessons begin. Reduction of personnel and operating costs through automation Automating window operation significantly reduces the effort required for manual ventilation. This saves time and minimises the risk of operating errors, especially in large buildings with many rooms. Centrally controlled systems can ventilate entire wings of buildings simultaneously, making maintenance, control and opening processes more efficient. Neither teachers nor facility managers are responsible for opening and closing all windows in short periods of time, such as during breaks or early in the morning before school starts. This also ensures that no windows are left open unintentionally: their status can be viewed at any time, and any error messages – for example, in the case of blocked windows – are displayed automatically. Energy efficiency through demand-based ventilation Uncontrolled or excessive ventilation leads to energy losses – especially during the heating season. Electric window drives allow ventilation intervals to be precisely controlled and adjusted to actual requirements. In combination with heat recovery systems or night cooling concepts, heating and cooling costs can be significantly reduced. In addition, windows can be closed automatically if the outside temperature deviates too much, which prevents further energy loss. This keeps children from having to sit in freezing classrooms, especially in winter, and reduces avoidable heating costs. Greater security thanks to reliable window technology Electric window drives increase security . Windows can be reliably closed using central control units or timer schedules. At the same time, the windows can be secured. This allows the closing edges to be monitored with a laser scanner to prevent fingers from getting caught. The IQ box Safety safety module stops or reverses movement as soon as a foreign object is detected in the danger zone. Another advantage: the window drives can also be used for enhanced fire protection, e.g. as a smoke vent in the event of smoke. Safety is paramount, especially in educational institutions where vulnerable children are present. Inclusion and accessibility Thanks to the option of operating the windows via tablet, smartphone or PC, they can also be operated manually by people with disabilities or remotely. Finally, electric drives can be integrated into smart building technology – for sustainable school architecture that is fit for the future. Smart building automation: advantages of control via KNX Corridor IQ box KNX HS controllers integrated into the customer's electrical installation cabinet. © Lorenz Frey / GEZE GmbH When controlled via a KNX module, the window drive responds to commands such as "open" or "close". The KNX system, which is not installed in the drive itself, but on site – this is in a control cabinet in the Lindenbüel Volketswil school building, – is what makes the system intelligent. Controlling the window drives via an intelligent KNX module offers a wide range of intelligent and flexible control options that can be used as needed.

GEZE Switzerland Ltd. was chosen as the partner for the planning, products and implementation of the project: with the GEZE Slimchain chain drive, GEZE offered an ideal product for the requirements of this project. In combination with the IQ BOX KNX , they are connected to the KNX module and thus integrate seamlessly into the on-site control system. Modern building automation can be used to achieve optimal ventilation. Centrally controlled, the drives open and close the fanlights in the classrooms and corridor, contributing to a pleasant indoor climate. Convincing measurement results: from sample windows to comprehensive retrofitting As a first step, the client initially wanted to convert a single room. After extensive consultation, a sample window was equipped with the GEZE Slimchain chain drive and the IQ Windowdrive. Data was collected and compared over the course of one summer. Outstanding data from the pilot project then provided the basis for conversion of the entire school building. In the further course of the project, a total of 121 drives, as well as associated electrical components, were installed. This extensive work was carried out in two stages: first, some of the classrooms, doors and corridor windows were converted and put into operation. Additional classrooms were added in a further stage. Both installation and commissioning were carried out by GEZE Switzerland. To ensure trouble-free operation, thorough instructions were given to the technical service on site. The customer is delighted with the smooth implementation of the project and the high-quality product: Working with GEZE Switzerland AG, our customers enjoyed a comprehensive, worry-free package – from expert advice and sample windows, which delivered convincing measurement results over an entire summer, to professional installation and handover. Nathan Grob, Commercial Technical Advisor at GEZE Switzerland Renovation during ongoing operations: Possible thanks to optimal project planning Completing renovations while operations are ongoing should be considered not only in schools, but whenever a building can only be vacated for renovation at great expense. At the Swiss school, this was possible with some restrictions, and the main objective – to keep the school running – was achieved. To this end, one part of the building was cleared during each construction phase, while lessons continued in the other part. This meant that the extensive work was not limited to the short time frame of the summer holidays, but could also continue during normal school hours. Refurbishment and modernisation during ongoing operations with GEZE GEZE is happy to provide support for refurbishment during ongoing operations right from the start of project planning. This allows the best possible process to be organised for all parties involved – from the building operator and users to the trades involved in the renovation.
