What is a Passive House?
Passive houses bring together innovative European building techniques with climate-smart thinking.
The first ‘Passivhaus’ was created by German Physicist, Dr Wolfgang Feist and construction expert, Professor Bo Adamson in the 1980s. Their ground-breaking approach reinforced five core principles which work together to achieve unique thermal properties and deliver exemplary standards of housing comfort and efficiency.
Passive houses are designed to keep excessive heat out and desirable warmth in. They’re cool during summer and cosy in winter. Remarkably, they use around 10% of the energy required to run an equivalent Australian home.
