The competition was run by the Department for Business, Energy and Industrial Strategy and has awarded funding for 75 council owned homes in the Paisley area to be upgraded with a series of deep retrofit measures to bring them up to EnerPHit standard (equivalent of Passivhaus for retrofit). These measures include new offsite prefabricated highly insulated timber panels fixed to the external walls and roof of the existing house which are then and clad in cement fibre board cladding. A very airtight external envelope combined with new triple glazed windows and Mechanical Ventilation Heat Recovery (MVHR) means the homes will be very airtight and energy efficient, without compromising internal air quality and comfort.
