Coldwells Build unveils a new certified Passivhaus range

Passivhaus is the world’s leading building standard for energy-efficient homes. It was developed in the 1980s by the German physicist, Wolfgang Feist, who set out to investigate why low-energy buildings weren’t delivering on their expected potential. He applied his findings to create Passivhaus – a physics-based method for building extraordinary, high-performance homes. Today there are 65 thousand Passivhaus buildings worldwide and it’s fast-becoming a popular choice for U.K. self-builders wanting homes with minimal energy and carbon demand.

Passivhaus homes are so insulated and well ventilated, they maintain a comfortable temperature year-round, with no draughts or cold spots and minimal heating needs. It keeps you warm in the winter months and cool in the summer, with significantly reduced heating bills. In fact, a Passivhaus cuts heating demand by 79%, compared to homes built to current Scottish building regulations and reduces lifetime carbon emissions by almost 40%.

Building a Passivhaus is complex. From hiring certified architects and contractors to design choices, material selections and layout decisions. For busy people who want the world’s best energy-efficient home, it’s a big commitment. That’s why we’ve distilled 3000+ decisions into one convenient package – the Coldwells Build Passivhaus.
