Reichstag, New German Parliament

Incorporating renewable energy systems, such as geothermal, biomass, solar, wind and hydro power generation

Reichstag, New German Parliament
Germany
1992 - 1999

The transformation of the Reichstag is rooted in four related issues: the Bundestag’s significance as a democratic forum, an understanding of history, a commitment to accessibility and a rigorous environmental agenda. The building provides a model for sustainability by incorporating photovoltaic panels and burning renewable bio-fuel in a cogenerator to produce electricity: a system that is far cleaner than burning fossil fuels. The result is a 94 per cent reduction in carbon dioxide emissions – the building’s energy requirements are modest enough to allow it to produce more energy than it consumes. Surplus heat is stored as hot water in an aquifer deep below ground and can be pumped up to provide heating or to drive an absorption cooling plant to produce chilled water.
