[Originally posted on Inhabitat.  I’ve pared down some of the pictures to fit it here; although Inhabitat runs on WP as well, the Inhabitat Gallery style doesn’t seem to come through.

This was something the Inhabitat editors found and asked someone to write about. I’m interested in looking into some of the concepts behind this even further, although the reference sites I had to use for research about this were auto-translated (badly; very, very badly).

But there were some intriguing things I came across and managed to puzzle out about low energy homes that I’m interested in exploring further. I had thought it might be a potential JetsonGreen article, but evidently Preston seees a conflict of interest in me writing for both JetsonGreen and Inhabitat, so unfortunately it looks like I won’t be wrting any more for him. I have a couple further thoughts about that on LiveJournal.]

This house in Leipzig, Germany designed by Atelier st combines contemporary styling with a degree of energy efficiency that comes close to Passive House standards. Yet the house features large expanses of glass that are unexpected for a house with the insulation requirements needed for such high performance. The residence is just 186 square meters (just over 2000 square feet), which is moderate by contemporary standards, but spacious for a 2-bedroom house, and its total annual energy usage is significantly lower than the electrical usage of the average American home.

The home’s exterior cladding is composed of vertical wood strips, which are intended to evoke the nearby woods and the rural setting for the house. The walls have 180 mm (7 inches) of insulation, and the few large windows have high-performance solar control coatings which allow the house to look nothing like an insulated box.

Solar collectors on the roof along with a fireplace heat-recovery system are the only means for heating the house. The house meets the standard for ‘Niedrigenenergiehaus’ (which looks like it may translate as ‘Low Energy Cost House’), a step below Passivhaus, with an annual energy use of below 60 kWh per square meter (5.57 kWh per square foot), or a total annual energy use of less than 11,160 kWh. That’s almost identical to the 2007 average annual American household use of electricity alone.
