Green building in Germany

German developments that employ green building techniques include:

The Solarsiedlung in Freiburg, Germany, which features PlusEnergy houses.
The Sonnenschiff in Freiburg, Germany, which is also built according to German solar architect Rolf Disch PlusEnergy standards.
The Vauban quarter, also in Freiburg.
Houses designed by Baufritz, incorporating passive solar design, heavily insulated walls, triple-glaze doors and windows, non-toxic paints and finishes, summer shading, heat recovery ventilation, and greywater treatment systems.
The new Reichstag building in Berlin, which produces its own energy.
The Heichrich Böll Siedlung in Berlin-Pankow as a forerunner for Green Building in post-cold war Berlin emphasizes on "every day ecology", instead of High-Tech-Measurements.

In January 2009, the first German certificates for sustainable buildings were handed over. The standard for the new certificates is developed by the DGNB and the BMVBS
