Ventilation and fire protection for Copenhagen car park
… combat this issue since it opened in June 2016. This car parking facility is operated by Jeudan, Denmark’s largest listed real estate and service enterprise, and was designed by Lundgaard & Tranberg Arkitekter. It is located in the centre of the Danish capital, under an area of the remodelled Kvæsthus Pier known as Ofelia Plads. It is among the most modern facilities in Copenhagen and offers convenient quality, modern design and outstanding safety. Chain drive with an attractive design: GEZE Slimchain ensures fresh air supply The stairwells’ unique design disguises the windows. © Morten Bak / GEZE GmbH Ensuring a supply of fresh air for everyday ventilation and rapid smoke extraction in the event of a fire is essential in modern buildings like the Kvæsthusmolen underground car park. Smoke and heat extraction (SHE) systems are a legal requirement for many buildings. Ventilation systems for underground facilities require particularly careful consideration and intelligent integration. For this reason, GEZE Denmark was involved in the planning process from the outset alongside the architectural office Lundgaard & Tranberg. Visitors can access the escalators via the rust-brown cubes at ground level above the parking complex. Electric Slimchain chain drives painted black have been fitted vertically to side-hung windows and ensure both efficient ventilation and effective smoke extraction. As a result, these chain drives fulfil stringent requirements in relation to both function and aesthetics. The GEZE Product Management team at the company’s headquarters in Leonberg, Germany, also helped to develop this special solution. GEZE provided great support throughout the project, both to the architects and builders and, of course, to us. They helped to make sure that optimised processes were in place and showed considerable flexibility on a project subject to stringent requirements in respect of design and functionality. Martin Steen, Project Manager at Jeudan Electric door drives provide fresh air when smoke forms or temperatures rise The second GEZE solution installed at the facility comprises a special enclosure for the entrance area and six hinged double-glazed doors. The glazed doors shield the entrance to the escalators against rain and snow. Equipped with the GEZE Slimdrive EMD Invers , these doors automatically open within seconds in the event of a fire or smoke alarm and remain open until the fire alarm is manually deactivated. The door automation systems and the turbines installed in the lower storeys interact to ensure that any smoke is quickly removed. The special ventilation solutions ensure that plenty of replacement air reaches the lower levels, ensuring ventilation in everyday operation and in the event of a fire and smoke build-up.

GEZE offers smart smoke and heat extraction solutions that interact flawlessly: Electrical opening systems for windows and doors, including chain and spindle drives Locking drives for added safety for large SHE or ventilation windows Opening/locking systems made up of an electric spindle drive and a mechanical fitting set Air supply systems to provide the necessary cross-ventilation in the event of a fire GEZE emergency power supply unit for all SHE components Interface modules to facilitate smart networking Additional accessories such as buttons and sensors Ofelia Plads and the underground car park are a showcase project and a lot of money was invested in their design. We therefore needed a customised glazed enclosure. GEZE provided expert advice and quickly developed solutions with automated ventilation that matched the building’s design and colour. In addition, the solutions meet in full the high safety requirements and standards new buildings must fulfil in relation to smoke and fire protection.

Fire protection doors as fire barriers
… combat fire Whether public facilities, office buildings or schools – people primarily judge buildings in terms of comfort, functionality, aesthetics and safety. In particular, the demands on safety technology have significantly increased in recent years - particularly in the area of fire protection. The risk of fires in buildings is high, and the numbers are alarming for Germany alone: Around 200,000 fires per year An average of 125,000 euro of operational fire damage Around 200 big fires with millions of euros of damage and devastating effects: 40 per cent of businesses file for insolvency immediately after the disaster, and 70 per cent within a year. Fires are vicious and unpredictable. They usually come as a surprise and cause huge damage. Which is why targeted protective measures are needed to tackle building fires. What does fire protection mean? Fire protection doors as a technical plant fire protection tool © Jürgen Pollak / GEZE GmbH Fire protection covers all protective measures which prevent the occurrence and spread of fires and smoke, and which permit self-rescue and effective extinguishing actions during a fire. There are two types of fire protection: preventive and defensive fire protection. The key role of preventive fire protection is to protect escape and rescue routes from fire and to keep them smoke-free. This also contributes to efficiently avoiding damage in the event of a fire. Preventive fire protection consists of structural, technical and organisational measures: all structural fire protection measures involve creating or adjusting structural systems. They focus on how materials behave in a fire and on components’ fire resistance properties. The technical system aspect of fire protection covers all technical systems such as fire alarm systems, fire extinguishing systems, smoke extraction systems and fire protection doors. Organisational fire protection relates to appointing fire protection officers, fire maintenance officers, preparing fire protection plans and the Fire Protection Ordinance. Conversely, defensive fire protection covers all measures which effectively extinguish a fire that has broken out. This is predominantly a task of the fire service. Fire protection doors as effective fire protection closers Fire protection doors play a key role in preventive fire protection. The key task of self-closing doors is to prevent fire from breaching openings in fire-retardant or fire-resistant walls. It is critical for doors to close reliably in the event of a fire. Fire protection door fire resistance classes How long a fire protection door remains fire resistant depends on its fire resistance class. Classification is currently governed by the German standard DIN 4102-2. In the future, this will be governed Europe-wide, based on the European standard DIN EN 13501-2 and the product standard DIN EN 16034. As a result, the names of the classes will also change. At this moment in time it is not clear when the European regulations will have to come into effect. The new European abbreviations will in future be: Show more Show less Building inspection requirement Product Abbreviation according to DIN 4102-5 Use in accordance with DIN EN 16034 and classification in accordance with DIN EN 13501-2 Fire-retardant, tightly closing, self-closing Fire protection closer T30 EI2 30-SaC...
