Ventilation supply

Air handling

HL BS EPG
The air handling system to be applied in the room is indicated here. This may be e.g. an air handling unit with heat recovery and coils for heating and cooling, or a system with natural supply and mechanical exhaust. The input data can be found in the resource Air handling. The type of system is displayed next to the air handling system on the screen.

NOTE: For individual dwellings and some non-residential buildings, a single ventilation system is applied. Therefore, this should be indicated in rooms with e.g. no mechanical supply. The system is defined for (a part of) the building, i.e. not for individual rooms.

Selected system

The selected ventilation system is determined automatically based on the input values of the air handling system.
