Residential Ventilation (HRV) in Berlin
Controlled ventilation with heat recovery.
Controlled mechanical ventilation (KWL – Kontrollierte Wohnraumlüftung) with heat recovery provides continuously fresh air while saving up to 90 % of ventilation heat losses. It is standard in modern low-energy and passive houses – and increasingly popular in Berlin old-build properties too. We plan and install KWL systems for residential units from 50 m².

Frequently asked questions about Residential Ventilation (HRV) in Berlin
In refurbished buildings with good insulation and new windows KWL is very beneficial. In unrefurbished old-build properties with leaky windows, decentralised ventilation may be the better solution. We advise individually.
Modern KWL units operate at 20–35 dB(A) under normal conditions – quieter than a refrigerator and barely perceptible during sleep.
For an apartment (70–100 m²) total costs including duct network and installation range from €5,000–12,000, depending on unit class and duct routing.
