4.6.1 Recommendations for
Buildings with Very Low Heating
Requirements
E.g. passive house and efficiency house

Circulating air extractor systems are to
be preferred from an energetic point of
view, taking into account ventilation
heat losses and fan power
consumption.
Exhaust air extractor systems are
possible. The following points have to
be observed:
•
Solutions for the additional flow are to be
provided. The exhaust air opening or air vent
opening has to be provided with tightly
closing closures. Simple non
- return valves are
not sufficient.
•
Impairments with regard to comfort cannot
be ruled out. The aim should be to find
solutions that allow the fresh air flowing in to
the hob to be introduced in the immediate
vicinity of the hob.
•
Extractor systems should be used which limit
the running time and reset the max. flow rate
after a time interval (automatic).
•
Preference should be given to systems with
moderate exhaust air volume flows to ensure
a sufficient capturing. As investigations of
capturing vapours have shown, there are
considerable differences between the
individual products. The air flows required for
capturing a defined quantity of vapour
differed by up to 60% in the investigated
systems.
•
In small apartments, the additional ventilation
heat loss significantly increases the heating
demand and also the heating load. Extractor
systems should therefore not be used in such
types of buildings if the average size of the flat
is less than 90m
