Office building Baumschlager-Eberle: a building without heating

Source: Detail; photo: Jakob Schoof

The architects from Baumschlager-Eberle have built a very special office building in Lustenau, Austria, partly for their own office, partly to be rented.
Although it was not their intention to build a building according to passive standard, it has become a real passive building, since the building has no heating system (and no mechanical ventilation).
More details can be found in Detail and at their website.

The AI PassivHaus in Scotland

The AI Passivhaus in Scotland was the first certified passive house in England (in 2009). It partly is a renovation of a barn and partly a new, underground building to reduce the visual and environmental impact on the landscape to a minimum. Very interesting is their extensive blog on the construction process with a huge amount of pictures.
