Single-family house the Technical University in Munich is planning to build in Fürstenfeldbruck that will combine passive energy conservation with a rooftop photovoltaic array that can produce about 6000 kW/year, Süddeutsche.de wrote, and thus take care of the family’s energy needs. About one-quarter of the electricity generated will be surplus to the house’s requirements and could be sold back into the grid or used e.g. to recharge an electric car. In good weather, the family could thus be able to drive approx. 150 kilometers/day on rooftop sunlight alone, totalling ~11,000 km/year in Germany’s climate.

A four-person family is scheduled to move in and test drive the house for one year after construction has finished in August 2014 and the engineers have checked all the systems.

Construction is projected to cost about 350,000 euros.

Car exhaust limits.

Update on 29 Nov 2013: The E.U. resolved a dispute about tightening car exhaust pollution standards in which Germany was trying to get laxer standards to appease its large large-car manufacturers. The E.U. ministers compromised on delaying the stricter standards by one year until 2021, when max. 95 g carbon dioxide per kilometer will be permitted for new cars.

The one-year delay will make the 95 g/km rule apply for 95% of new cars in 2020 and 100% in 2021. ZDF heute journal financial correspondent Valerie Haller said German manufacturers sell heavier cars than French and Italian manufacturers, so they will benefit well from the extra year to develop compensating technology. Also, the new rules say only 4 L/100 km of gasoline can be consumed, which small light cars manage but heavier cars will need electric motors to accomplish. Car manufacturers’ supplier Bosch said that practically means the end of purely-gasoline or purely-diesel “grosse Klasse” cars, meaning I think the big expensive German automobiles. Road traffic is one of the top three air polluters, Ms. Haller said, and the E.U. has promised to reduce its air pollution to try to mitigate the disasters that will be caused by climate change.

A similar fight happened in 2013 over E.U.-mandated use of a more environmentally-friendly fluid in new cars, with France filing a complaint stating that German car manufacturers were out-of-compliance and German car manufacturers responding that their in-house tests had found the new fluid spontaneously combusts sometimes.
