Fensterbeschreibung des Systems: |
For the purposes of certificaiton a standard passive house window (Veka Pkastics Shanghai Ltd. Softline 82 MD PSR, Uw = 0,80 W/m²K with Ug = 0,70 W/m²K) was used. The overall U-value of the installed window of standard size (1,23 m wide by 1,48 m tall) should be no more than 0,05 W/m²K greater than the Uw to ensure occupant comfort - this criteria is met in this instance. |
Luftdichtheit des Systems: |
Airtightness of the system is achieved in the following way: windows and doors are installed with permanently elastic sealing materials and suitable airtight connection membranes and profiles. The interior of exterior wall surfaces are plastered over the entire surface, down to the unfinished floor and up to the unfinished ceiling. The interior of external walls for lightweight construction are covered over to the interior with continuous airtight membranes, with joints sealed using suitable airtightness tape. |
Beschreibung der opaken Gebäudehülle: |
With the Light Steel Construction System the wintertime thermal insulation of buildings can be ensured. The system is constructed out of lightweight steel profiles, connected using timber/OSB connectors. The assembly is insulated to the outside and within the service cavity using mineral wool (=0,04 W/mK) and with EPS (=0,035 W/mK) to the interior. For the purpose of certification, a number of three-dimensional simualtions were carried out to determine the effective thermal conductivity of insualtion plus steel profiles where these create regularly occurring or point thermal bridges. The certification does not take into account point thermal bridges caused by structural columns or e.g. balcony connections, which will need to be assessed separately. As investigated, the system is deemed suitable for passive houses in the cool-temperate climate zone, as both the regular U-values of the exterior components are below 0,15 W/m²K and the connections meet the criteria of 'thermal bridge free'. The surface temperature of all connections (with the exception of window connections) meet the surface temperature requirements. |
