Summary

Machine-generated summary

The works cover the renewal and extension of the heat supply for the existing buildings and the new multi-purpose building at the Langwiesen school. The existing buildings will be supplied via 40 geothermal probes of 135 m each (tendered separately) and two brine-to-water heat pumps, replacing the existing gas boilers. The new multi-purpose building receives two air-to-water heat pumps plus a booster heat pump for hot water generation. Heat distribution in the existing buildings will be adapted and extended; the new building uses underfloor heating and air heaters. Scope also includes free cooling, hot water storage, metering, control and regulation technology, plus delivery, installation, commissioning and balancing of all heating systems.
