Passive House Requires High Performance Windows

Passive House (passivhaus) principles are beginning to generate a lot of interest here in Australia. These principles were formed in Germany back in 1991 by Dr Wolfgang Feist, but are now known worldwide. In order to achieve this special certification a building needs to perform exceptionally throughout the year, and require less than 15 kWh/m2/yr of energy to heat or cool.

High performance windows are relatively new to Australia, but have been widely used in places like Europe for over 30 years.

Anyone who wants to achieve passive house certification must have high performance windows with u-values less than 1.5.
