ABSTRACT
This chapter shows how Passive House can help to deliver a renewable-energy revolution. Passive House makes it possible to reduce energy demand by up to 90% compared to ordinary buildings. Because Passive House buildings are so cheap to run, they offer affordable comfort. They provide warm and dry spaces in winter, without any condensation at all, and are always full of fresh air. Occupants say how they never feel too warm or too cold, and say how they appreciate the quality of the air in Passive House buildings. The Passive House methodology requires the use of the Passive House Planning Package to accurately measure energy flows in a building. The Passive House methodology is complementary and compatable with low embodied energy. In proportion to their energy efficiency, Passive House buildings achieve significant in-use carbon-emission reductions compared to the carbon emissions of ordinary buildings. A co-heating test is a method of measuring a building’s whole heat loss or heat loss coefficient.
