A key factor of insulation system performance is the installation.
European Passivhaus tailored for North America in new standard
The final format of the new standard is uncertain, but it could be zone-based or centered on an equation
The European Passivhaus metric isn’t necessarily well suited to varied climate zones outside of Central Europe, so a new standard is being developed that will address all U.S. climate zones. Preliminary results are looking very promising, says Katrin Klingenberg, co-founder and executive director of Passive Haus Institute U.S. PHIUS is already accepting projects under a pilot certification program. The final format is still to be determined. Originally, a zone-based standard model was envisioned, but the study may produce an equation that accurately calculates the respective heating, cooling demand, and peak loads by location.
