Passive House Principles: Mechanical Ventilation Heat Recovery

A Mechanical Heat Recovery Ventilation (MVHR) system brings in fresh outdoor air into all habitable areas without letting heat escape. Units continuously remove unwanted moisture and airborne pollutants, and provide improved filtered internal air quality. This means that you do not need to rely on opening your windows to achieve good indoor air quality.

This system helps retain over 90% of heat and keeps a consistent indoor temperature. This lessens the need for mechanical heating and cooling which will save on energy bills.

All Oknalux windows and doors meet the requirements of Passive House principles, and we are proud to say that our products have helped to achieve Adelaide’s First 10 Star Home (2020). 10 Stars is the highest rating that can be achieved in Australia. This star rating system is slightly different to the Passive House principles, however, many of the same principles are used in both and a 10 Star home is considered ‘passive’ as it doesn’t require heating or cooling for internal comfort all year round.
