Glazed surfaces on facades of buildings, whether residential or not, are the elements through which most heat is transferred. State-of-the-art construction and insulation materials as well as structural solutions of external partitions currently used have thermal transmission coefficients Ug equal to approx. 0.15 W/m2K, but for windows this figure is 0.6 W/m2K.
In residential buildings, window surfaces represent at least 15% of the external surface of the building, and this proportion reaches 80% in public buildings. This means that at least 40% of heat escapes through windows.
Any further progress in the direction of widely implementing the passive or zero energy building concept, which needs minimal energy for heating, depends on a technological break-through in thermally insulating glazed elements, i.e. insulated glass units, window frames, glass facades and curtain walls.
The purpose of the SUPERWINDOWS project is to introduce a new generation of heat-insulating glazing systems (insulated glass units and glass facades) with extreme thermal and optical parameters which could not be achieved both at the same time before (R>10 Uw70% of visible solar light transmitted).
We are glad to announce that we have been awarded in Innowator Małopolski Prize.

Two architects from Brute Force Collaborative (Seattle, US) posted their impressions on our ideas here.
“The last highlight for me, and I’ll definitely do a summary post on this in the next few days, was the SUPERWINDOWS presentation from the idea generators at Kostka & Paszkowski (Poland). They presented a series of conceptual ideas that literally had my jaw on the floor and caused me to murmur, ‘no f*cking way!‘ every 2 minutes. Let’s just say it was a good thing I was in the back of the room. Though far from production ready, this outside the box thinking verifies why we need to keep the standards for Passivhaus stringent – this is really what is driving innovation. The SUPERWINDOWS presentation took the idea of innovation to an extreme, bypassing incremental steps to a whole new concept of glazing. In modeling, it’s appearing to achieve U-values of 0,1 – 0,3W/m²k (R-56 to R-19) – which makes the whole wall v. glass debate completely moot. A Miesian glass Passivhaus could finally be realized in Moscow. Game. Set. Match!
Finally, while a number of us were hoping the 17th PHI conference would be in Brussels, it is set for Frankfurt on 16-17 May, 2013. We look forward to seeing you then!”
