DIN 1946-6 and window ventilation

Purpose of the work

Is a ventilation system mandatory in airtight buildings? To what extent can users still be responsible for ventilation in modern buildings?

Method of approach

Evaluation of decision-making criteria for ventilation; normative specifications for the ventilation concept; energy efficiency potential of ventilation

Content of the contribution

Infiltration through leaks? A careful analysis of minimum air change according to DIN 1946

Purpose of the work

Can the minimum air change in naturally window-ventilated units be covered only through leakages?

Content of the presentation

In general, the infiltration airflow rate is dependent on meteorological conditions, especially wind pressure on the building / unit, and with regard to thermal effects, the temperature differential between the interior and the exterior, i.e. the infiltration airflow varies strongly.
