Adiabatic cooling in the Technologie- und Gründerzentrums (TGZ) in Hubland, Würzburg


Within 3,600 m² of the newly built technology building, start-ups will be provided rooms, services, consulting and networking. The planned usage for the building is for offices and training rooms as well as a 600 m² workshop for test facilities. The building achieves the KfW 55 passive house quality standards. The TGZ gives youg start-ups a home and provides the opportunity, through its connection to the university, for intensive knowledge transfer.

Especially smart is the INTEWA rainwater system with AQUALOOP disinfection for adiabatic evaporative cooling. In comparison to conventional cooling systems, it can save up to 80% of energy expenditure. The use of a reverse-osmosis system is no longer necessary as the rainwater is mineral poor.

Start date: July 2014
Opening: February 2016
Total project cost: 11.825 Mio. EUR

System components:

  1. 2 AQUALOOP membranes for disinfection of the rainwater
  2. Rainwater tank with a useful volume of 25.7 m³
  3. Pre-filtering with a PURAIN 200 rainwater filter
  4. RWZ-14-60-P for WC, urinals and grounds irrigation
  5. Submersible pump Multi-04 for supplying the adiabatic cooling

The possibility to save drinking water has enhanced strongly the last years.
