WHAT IS A PASSIVE HOUSE?
A Passive House is a well insulated, virtually airtight building that is primarily heated by passive gain. This means that the building's interior climate can be maintained at a comfortable level without active heating and cooling systems - the house heats and cools itself, hence 'passive'.
A Passive House combines high-level comfort with low level energy consumption using key components like insulation, thermal windows and heat recovery.
The term Passive House refers to the rigorous, voluntary, Passivhaus standard for energy efficiency in a building, designed to reduce its ecological footprint. The pioneering achievement that is Passive House design has become the internationally recognised standard for sustainable architecture, and is becoming widely used throughout the world.
