The forecasts, based on research with window manufacturers across Europe, including 50 UK manufacturers, says windows with U-values of 0.8 W/m2K or below are expected to have expanded to 10% of the market in the UK, 25% in Germany, 30% in Austria, and up to 35% in Switzerland by 2020.
Passivhaus is the world’s leading ‘fabric first’ approach to low energy building, promoted by the Passivhaus Institute and the BRE in the UK.
Passivhaus aims to dramatically reduce the need for space heating and cooling, and typically cuts energy use and CO2 emissions by a factor of 10.
The standard requires a Passivhaus to have an excellent thermal performance, exceptional airtightness and mechanical ventilation.
The heating requirement in a Passivhaus is reduced to the point where a traditional heating system is no longer considered essential.
It’s the fastest growing energy performance standard in the world. There is a short animated video on their website that explains it simply: http://passivehouse.com/.
SWISSPACER’s Ultimate warm edge spacer bar is Passivhaus certified, allowing it to be used on any Passivhaus project.
But achieving the certification plays only a small part. It’s what you do with it that matters, because certification doesn’t necessarily mean your product will be specified.
Experience, expertise and commitment to helping specifiers and developers achieve Passivhaus projects are what matter.
SWISSPACER is the leading warm edge spacer in Passivhaus, specified in the majority of Passivhaus windows and curtain wall systems.
The Passivhaus database of certified components (http://database.passivehouse.com/en/components/) lists SWISSPACER in 70% of windows, 86% of windows with fixed glazing and 97% of curtain wall systems. Low energy domestic and commercial buildings have a big future, and specifiers, developers and installers can rely on SWISSPACER’s experience to help them take advantage of it.
