The air-to-air heating pump provides the heating in winter.
The water is heated with the residual heat from the cooling of the air-conditioning. When this is insufficient, the air to water heat pump takes over.
Further we make use of daylight through skylights and indirect lighting with LED-lights.
With the Passive Shower up to 40% of the energy needed to heat shower water is saved.
