Energy efficiency in buildings

Basic knowledge energy efficiency in building services engineering

Water Air
Soil             Waste
Heat supply and air conditioning
Significant savings can often be achieved just through simple measures and the more conscious use of energy. In the field of building heating, the necessary energy can be reduced by more than 80% through a combination of measures in some cases.

Energy efficiency in business and industry
On these pages we have compiled only a very small selection of devices on this topic. The basic approach to analysing energy flows in given application environments in order to achieve a reduction of primary energy use can also be demonstrated by many devices from our standard product range, in addition to our 2E devices.
