Roof Windows for Passive Houses – What Can Be Improved?

Popis výsledku v původním jazyce

In general, skylights and roof windows in pitched roofs can be described as the critical components of buildings concerning heat losses, risk of surface condensation, increased risk of overheating of rooms behind etc. This is very sensible task especially for passive house solutions. The paper informs about studies analyzing the importance of these relatively small areas in the building envelope and more detailed in pitched roof of a passive house. One of the key problems is the position of roof window within the pitched roof construction. Second part of the paper comments results of detailed analysis of thermal performance for different combination of frame type and glazing. These studies are performed hand in hand with development works. It is documented that such approach can lead to promising results, reducing the thermal transmittance of roof window to 0.7 – 0.5 W/(m2K). If we consider the real roof window quality including the thermal couplings due to window installation such thermal transmittance stays safely bellow 0.9 W/(m2K).
