A modern concept for office buildings: energy saving and good indoor climate are no longer contradictory.

An up-to-date design concept for office buildings results in a very low energy consumption and provides a better indoor climate at the same time. This new concept is based mainly on two design features: An extremely well insulated building envelope decouples the indoor climate from the outside climate to a high degree during all seasons and weather conditions. The second element of this new design concept is the HVAC-system: The source-dominated displacement ventilation provides a better comfort and, as a cosequence of its high effectiveness, is very economical.
