Passivhaus: the gold standard
in energy efficiency
Allowing 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. Passivhaus windows make efficient use of the sun, internal heat sources and heat recovery, rendering conventional heating systems unnecessary throughout even the coldest of winters.
Passivhaus buildings are praised for the high level of comfort they offer.
Internal surface temperatures vary little from indoor air temperatures, even in the face of extreme outdoor temperatures. Special windows and a building envelope consisting of a highly insulated roof and floor slab, as well as highly insulated exterior walls, keep the desired warmth in the house – and undesirable heat out.
