Today, Mechanical Ventilation Heat Recovery (MVHR) is a recognised method of ventilation in the domestic Building Regulations (ADF2003), representing an energy efficient whole house approach which is suitable for both apartments and houses.
MVHR is a balanced ventilation system, extracting and supplying equal levels of air around the dwelling, providing a controlled system for the building. As ventilation now has more impact on heat loss from buildings, energy savings from motor consumption and air tightness are driving the design and installation of new technologies. MVHR is just one of the more efficient methods that is favoured in SAP and can help reduce DER’s (dwelling emissions rates) in a cost effective way.
