Germany: Solar Heating Saves more CO2 than Maximum Insulation

Submitted by Baerbel Epp on June 1, 2012

 Sonnenhaus Solar thermal heating makes houses up to 67% more energy-efficient than a perfectly optimised building envelope. This is the result of a paper which compared the efficiency of solar thermal systems with building insulations. The study, which was commissioned by the German Federal Solar Industry Association (BSW Solar) and carried out by the German Sonnenhaus-Institut e.V. (Solar Houses Institute) and engineering firm Econsult, found that structures with a high solar thermal coverage are significantly more environmentally-friendly.
