Germany: Bank Builds Solar House for Alternative Pension Scheme

Submitted by Baerbel Epp on October 4, 2016
Verlagsgruppe KampradTopping out a new primarily solar-supplied residential building in Germany is not really news anymore, especially because there have already been more than 1,800 solar houses set up all across the country, according to November 2015 statistics by the association Sonnenhaus-Institut (Solar House Institute). What’s special about this topping out ceremony on a solar house in Schmölln in the region of Thuringia at the end of August 2016 is the fact that the investor is a bank. The building is planned to cover 55 % of its heat and 100 % of its electricity demand by solar. With it, local cooperative bank VR Bank Altenburger Land wants to demonstrate to its members and clients what smart living will look like in the future.

riedel_leukefeldProf Timo Leukefeld and Stephan Riedel, solar experts and members of the Solar House Institute (Sonnenhaus-Institut), have won this year's Renewable Energy Award, or Renergy Award for short. The first award of its kind was presented at the CEB Clean Energy Building fair in Stuttgart, Germany, on 6 March 2014. It honours sector professionals for their commitment and their innovations in the field of renewable energies. The photo shows Stephan Riedel and Timo Leukefeld (right) in front of one of the experts’ self-sustainable solar houses in Freiberg, in the east of Germany.

Germany: Solar House Trend towards Multi-Family Buildings

Submitted by Baerbel Epp on December 15, 2013

2013 will have been the first year in which the Sonnenhaus-Institut (Solar House Institute) has felt the effects of the general downward trend in the solar thermal market. According to a press release, the knowledge platform’s 14% increase in buildings in 2013 (176 new houses) marks a notable drop from previous years. The 250 solar houses built in 2012 still represented a growth rate of 20%. This is why the participants of the general assembly at the end of November rather looked to the future than to the past: There are already plans to set up around 300 mainly solar-heated houses in 2014. The association relies on data from its members to determine the number of newly built solar houses. This year, only 40 of these members sent back the questionnaire, instead of the usual 60 to 80.

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.
