Passive House comfort criterion
A minimum supply air temperature of 16.5 °C is main tained at an outdoor air temperature of -10 °C.
Efficiency criterion (heat recovery rate)
The effective heat recovery rate is measured at a test facility using balanced mass flows of the
outdoor and exhaust air. The boundary conditions for the measurement are documented in the testing
procedure.

Efficiency criterion (electric power)
The overall electrical power consumption of the device is measured at the test facility at an external
pressure of 100 Pa (50 Pa, respectively, for the intake and outlet). This includes the general electrical
power consumption for operation and control but not for frost protection.

Efficiency ratio
The efficiency ratio provides information about the overall energy performance of the respective
ventilation unit. It specifies the achieved reduction in ventilation heat losses by using a ventilation unit
with heat recovery rather than without.
