One year of realignment at Sonnenhaus Institut

In order to qualify as a Sonnenhaus, a building must cover at least 50% of its heating requirements using solar energy. Solar thermal energy is usually used for this purpose. (Photo: Schlagmann Poroton/ Sonnenhaus Institut)

2015 was the first full calendar year following the realignment of the Sonnenhaus Institut, which allowed the combination of photovoltaics and heat pump for the first time. Most Sonnenhaus homes are still heated using solar thermal systems, but photovoltaics are also finding their place.

On the first of January, strict rules for construction came into effect in Germany. Heating new buildings without using renewable energy is nearly impossible. Oil heaters will probably not be used anymore in new single family houses.
