Type
NTDH
Short description
NTDH utilizing excess heat and PTV for heating
Location
Suurstoffi district-Risch Rotkreuz
Country
Switzerland
End users
Office complex, residential objects, schools, administrative and sports buildings
Heat source
Ground/Excess heat/Solar
Description
Excess heat from free cooling and heat from solar collectors regenerate soil (seasonal storage) which then heats network connected to HPs at substations for SH and DHW; Solar energy is also used directly for SH and DHW
Cooling
Yes
Heat source-network connection
HEX? (ground and excess heat Missing info); Solar collectors
Booster HP or no for SH
HP (for few buildings)
Booster HP, IHEU or DHSU for DHW
HP (for few buildings)
TES
Vertical ground HEX (215 boreholes 150 m depth and 180 boreholes 280 m depth)
Centralized/ Decentralized TES
