Geothermal heat pump
An underground heat pump system at Kameha Grand hotel in Germany that uses six geothermal wells at 28 meters depth to provide heating and cooling for 80,000 square feet of building space, supplying all cooling and 70 percent of heating needs while saving approximately 1,700,000 kWh annually.

Variable Refrigerant Flow (VRF)
A heating and cooling system that uses variable refrigerant flow technology to condition building spaces. Commonly used in commercial buildings as an alternative to geothermal systems.
