What is Passive House?
Passive House is a design and construction methodology for creating very thermally-efficient buildings. Passive House buildings allow for space heating and cooling-related energy savings of up to 90% compared with typical building stock and over 75% compared to average new builds. Although Passive House buildings have been around internationally for 25 years, at last, these super energy-efficient buildings are now appearing in Australia.
Passive House buildings show great diversity in aesthetics, size, construction methods and materials. The following five details enable buildings to achieve the Passive House standard:
-Exceptionally high levels of thermal insulation;
-Well-insulated window frames with double or triple low-e glazing;
-Thermal bridge-free construction;
-Air-tight building envelope;
-Comfort mechanical ventilation, with highly efficient heat recovery.
These principles, together with good orientation, window shading and efficient design comprise a building that is very thermally comfortable and energy efficient.
