Affordable housing constructed to a certified Passivhaus standard in a rural location

The 14 dwelling development includes six one-bed flats, five two-bedroom houses and three three-bedroom houses all constructed to Code for Sustainable Homes Level 4 and also to Secure by Design and Lifetime Homes standards.

The houses, which have traditional trussed pitched roofs on thin joint blockwork, are externally insulated and rendered with triple glazed composite windows and supported off an insulated raft. The layout employs south facing private gardens and passive solar gain techniques, as well as sophisticated solar shading elements to prevent overheating.

The highly insulated structures and thermally bridge free detailing provide an effective building fabric which, when combined with detailed solar and occupancy gains and mechanical ventilation with heat recovery deliver exceptional energy performance.

The homes are being fully monitored for two years by UEA to aid understanding of the energy savings that accrue through use of Passivhaus techniques.
