Buildings

About 90 percent of domestic energy consumption in Germany goes on heating and water. Space heating accounts for the major share by far – i.e. around three-quarters of domestic energy consumption, with much of this being lost through walls, windows, the roof, doors or floors. Old boilers and oversized, incorrectly set and inefficient circulating pumps also send electricity and heat consumption soaring.

Existing buildings need better insulation and inefficient heating systems must be replaced by modern facilities. Mini block-type thermal power units are particularly efficient. Innovative concepts are needed for new buildings. After all, who wants to heat the outdoors instead of the living room? In existing buildings, energy demand can even be reduced by as much as 90 percent but with an average reduction potential of at least 50 percent.
