We also support you on the subject of sustainability. We optimize your system technology so that your property can meet the requirements for saving energy and protecting the environment. In addition, to protect human life and property, we check the functionality of the fire protection systems at prescribed intervals. We do everything to ensure that your building technology works well, thus helping you to conserve resources and increase the profitability of your building.

We plan, advise, and implement for you in the following areas of building technology:

  • Gas, water, and wastewater technology: Plants and facilities for sanitary technology with water treatment and wastewater treatment including fire extinguishing technology.
  • Heat supply, domestic water heating, and air conditioning systems: heating, hot water systems and solar thermal systems, heat pumps.
  • Technical systems for rooms: CHP, air conditioning, ventilation systems, smoke extraction systems, process air systems, refrigeration and cooling technology, chilled ceilings.
  • Building control technology: automation systems, building automation systems, control and communication systems, control technology.
