Cre8 Barn
Download
as PDF WINNER of the UK Passivhaus Awards 2015 - The Cre8 Barn project is an innovative barn conversion to EnerPHit standard, which has transformed a derelict cow byre into an education centre for Yorkshire Wildlife Trusts Stirley Community Farm. The project features a box within a box structure (inner timber frame building within outer masonry barn) which preserves the outer appearance of the barn, while offering high levels of airtightness and continuity of insulation. The timber frame construction not only ensures thermal performance, but also helps provide structural stability to the outer masonry walls.
