Innovative door damper for indoor rooms – GEZE ActiveStop

… preset position. © Jürgen Pollak / GEZE GmbH It is not just patients and practice staff who benefit from the GEZE ActiveStop - so do the walls and equipment. GEZE ActiveStop brakes the door at the right time and keeps it open safely in the required position. This also prevents damage to walls and furniture in the vicinity of the door, making door stopper redundant. Thanks to active damping, the door closes slowly and quietly from about 25 degrees and prevents noisy slams as well as damage to the door, and injuries. The interior door opens easily with the new GEZE solution, and also closes securely - and all without a lock latch. The doors have 'free movement' at an angle between 25 and 60 degrees - an aspect which, according to Jule Kain, always causes patients to have an ‘aha’ moment. Innovative award-winning design German Design Award 2016 The GEZE ActiveStop has won two awards for its outstanding design. The innovative door damper received the German Design Award in 2016. This internationally renowned prize was awarded by the Design Council, the German brand and design authority.

Natural ventilation: air exchange for a healthy indoor climate

More air for better concentration In many schools, rooms are ventilated only when the weather is good or if the air quality is noticeably poor. This is often insufficient. A needs-based supply of fresh air can increase learning ability by at least 15 per cent. © Exorbitart / GEZE GmbH Topics Fresh air produced by intelligent window ventilation Buildings are becoming ever more tightly sealed for energy-saving purposes. This saves on heating costs, but requires intelligent ventilation to efficiently ventilate and aerate buildings. Natural ventilation provided by automated windows is a smart solution that significantly improves the indoor climate while consuming little energy and with low investment costs. People are generally not very good at providing adequate ventilation in buildings A good indoor climate depends on a number of factors. Temperature and air humidity both play key roles, but acoustic and visual aspects also contribute to well-being. But why is typical ventilation often insufficient? Whereas people respond well to thermal, acoustic and visual stimuli, they lack sensitivity to air quality. People primarily judge indoor air quality based on bad smells, but they get used to these smells the longer they stay in the same room and so they don’t notice a reduction in room air quality. We only notice “poor” quality air when it is too late. Efficiency drops, and people become sleepy or get headaches – due to excessive concentrations of CO … caused by people breathing. The situation is exacerbated by pollutants which can be emitted from furniture or carpets. Mandatory controlled ventilation Natural ventilation via convenient ventilation technology. © Exorbitart / GEZE GmbH Due to modern, energy saving construction methods, we work, live and learn in increasingly hermetically sealed buildings. The downside of this: not enough fresh air flows in, and moisture, heat and odours are not extracted effectively due to the insufficient rate of air change. However, the German Energy Saving Ordinance (EnEV) prescribes that buildings must be constructed in a way which guarantees the minimum rate of air change that is necessary for the purposes of health and heating. Controlled ventilation is therefore needed in a building which has been constructed in accordance with EnEV. A mechanical ventilation system is one solution. But who enjoys working or living in a building where you can’t open the windows because of the ventilation system? Many people feel uncomfortable in rooms where the windows are always closed. The alternative to this is controlled, natural ventilation via windows, which automatically draws in fresh air directly from the outside. Natural window ventilation based on temperature fluctuations and wind Natural ventilation – also known as "free" ventilation – achieves the exchanging of air through the windows without any mechanical ventilation system whatsoever. The required air flows are produced solely by the temperature and pressure differences between the internal and external air, and by naturally occurring wind flows. The "smart façades" themselves create the ventilation. This means that powered-operated windows are controlled by sensor signals, e.g. by weather stations or air quality sensors. Intelligent indoor climate regulation systems identify wind strength and direction, external temperatures and precipitation, room temperatures, air humidity and CO2 values of the indoor air, and they control the opening and closing of the automated windows accordingly. This type of window control is completely independent of the user, even when the building is empty. FIND OUT MORE ABOUT SMART FAÇADES Natural and energy-efficient ventilation In addition to CO2, classrooms or offices with a large number of people also generate a lot of heat. In the summer in particular, solar radiation often heats the room up even more. Natural ventilation can draw unwanted warm air out of the room towards the outside and so let fresh, cooler external air flow in. In the cool night-time period, free ventilation provides natural building climate control. This produces good air quality naturally due to the differences in temperature, without using any energy to supply and cool the air. Intelligent window ventilation makes a significant contribution to energy efficiency Sustainable and energy efficiency are important keywords in building design: How does the indoor climate change in the course of the day? What might summertime thermal insulation look like? And what about night-time cooling? Learn how GEZE window drives enable natural ventilation, solar input and night-time cooling – effectively supporting sustainability goals – through multiple practical examples and simulations. Greater convenience, safety and hygiene thanks to automated windows The risk of viral infections being spread can be higher in closed rooms because of aerosols. Consequently, a sufficient flow of fresh air provided through ventilation is recommended to improve indoor air hygiene. But if windows have to be opened manually, the contact involved can transmit bacteria, germs and viruses. Automated window drives, which can be operated in a non-contact way, increase convenience and safety for users.
