(*) detailed description of criteria and key values see attachment.
(**) for heating, domestic hot water (DHW), ventilation, auxiliary electricity in the reference
building, explanation see attachment.
(***) All key values of heat pump were measured with enthalpy (humid) heat exchanger.
The dry heat recovery was measured, too and is shown here alternatively.
All other key values are valid respectively for dry heat recovery, too.
