Airflow finds the volume flow for dwellings, internal rooms and occupied spaces. The methods follow DIN 1946-6, DIN 18017-3, DIN EN 16798-1, DIN 1946-4, DIN 1946-7 and VDI 2052. Room type, area and occupancy give the required flow.

How it's calculated

Airflow gathers the usual planning methods for dwellings, internal rooms and occupied spaces. Dwelling ventilation follows DIN 1946-6 from the area rate, the insulation factor and the nominal extract of the wet rooms. Internal bathrooms and kitchens follow DIN 18017-3. Offices and workplaces use DIN EN 16798-1 and the workplace rule, and, where selected, DIN 1946-4, DIN 1946-7 or the principle of VDI 2052. The result is the larger of the governing flows, not a sum of every standard.

Worked example

Dwelling of 90 m², three people, height 2.5 m, lower insulation, kitchen and bathroom: design flow 98 m³/h, set by area.

FAQ

Does this replace a DIN 1946-6 ventilation concept?
No. It sizes the volume flow from the table values. Wind, infiltration and the building ventilation concept stay outside.
Why is nominal ventilation not just the sum of the rooms?
The standard caps the wet rooms against the area rate. A large number of wet rooms is therefore reduced.
Which CO2 level is behind the person rate?
Workrooms offer the 800 and 1,000 ppm steps. Outdoor air is taken at about 400 ppm.
Is a patient room treated like an office?
No. Operating and patient rooms follow DIN 1946-4, laboratories DIN 1946-7, and kitchens an estimate in the sense of VDI 2052.
