A best-practice example of a sustainable energy building

As long as it keeps accounting for 40% of the EU's energy demand, the building sector faces the inevitable challenge of producting more efficient buildings whilst at the same time responding to ever more demanding occupants in terms of comfort.

Furthermore, there are a huge number of thistoric buildings in Europe still wasting large amounts of energy. Within a sustainable building approach, buildings renovation requires ambitious and encompassing energy concepts to be developed.

Since the realization of this exemplary project and the implementation of its energy concept, Europe's capital has been provided with a showcase for integration of innovative renewable energy and energy efficiency technologies in a 140 year-old listed building.

The REH thus demonstrates that its possible to significantly reduce any buildings energy needs and to deal with the multiple constraints in any site, to offer a 100% renewable energy answer.
