Polar bear lends hand to climate protection

The Passive House Institute, together with the Passivhaus Austria network, GLOBAL 2000 as well as the campaign MOTHER EARTH, has built two different mini houses for the ice block competition, a mini Passive House and a conventional mini house. A 250 kilo block of ice has been placed in each mini house. The question is, how much ice exactly will still remain in both houses after six weeks. Estimates can be submitted online. Press Release

"It was pleasantly warm even on cold winter days," says Erichson. As a Bahnstadt resident and also mayor of the city, he participated in the information event that was held on the fire station premises where the city administration presented its energy monitoring results together with the Passive House Institute. The two most important outcomes: the consumption of heating energy in the Bahnstadt district was extremely low. Simultaneously, the total energy consumption was only a third of that of conventional housing complexes. Press Release

Pioneer project upgraded to Passive House Plus

Photo: Passive House Institute The world’s first Passive House building has increased its already high energy efficiency level and now relies on renewable energy. About a year ago, a photovoltaic system was installed on the roof of a row house built in 1991 in Darmstadt. Since then, this pioneering Passive House project has been producing its own electricity, thus fulfilling the criteria of a Passive House Plus building. The official certificate was recently issued in Darmstadt.
