This energy is extracted by a ground source heat pump and transferred into the distribution circuit that heats the building.
The design also makes use of the heat given off by the IT department. Two-thirds of the building’s heat energy is supplied by geothermal or ground-sourced heat, with the remainder provided by conventional electricity supplies.
"This is the most cost-effective form of heating our new building," said company chairman Thomas Bauer. "This technology also allows us to operate the system in reverse to provide an element of cooling for the building during the summer."
A team of designers came up with the system including Munich-based consultant Weickenmeier, Hubert Krimmer, HGC and Saxony, which is part of the Bauer Environmental Group.
New Bauer subsidiary company EWN ErdWärmeNetz installed the borehole system for the building, which is due to be ready by early next year.
"If CO2 emissions in Germany are to be significantly reduced in the foreseeable future, by 20% or even 40%, then everybody has to make an effort towards achieving this goal," said Bauer.
