Passivhaus And Low Energy Design

Passivhaus is a German low energy building standard. Passivhaus buildings have almost no space heat demand and so do not require conventional heating systems. They also provide the best levels of thermal and environmental comfort whilst delivering significant carbon emission reductions.
At Aaben we use the Passivhaus design tool in many of our new build and refurbishment projects to achieve the highest energy efficiency.

This alternate Passivhaus standard can be used for refurbishment projects where the Passivhaus standard is impractical.
Passivhaus buildings save approximately 75% of the energy use of a current new build home.
