as PDF Transformed two semi-detached houses into super insulated homes for the future. The Retrofit Plus Research Project was a collaboration between Beattie Passive, Birmingham City University, InteSys and iZdesign under the Innovate UK initiative for Scaling up retrofit of the nations homes. The project involved retrofitting two houses to achieve EnerPHit performance with the aim to drive innovation in energy retrofit of homes that would achieve up to 100% carbon emissions reduction, drawing upon academic, technology start-up and private sector expertise.Beattie Passive used their innovative, highly insulated offsite system TCosy system to transform two semi-detached houses owned by Birmingham City Council.Using Passivhaus comfort and energy efficiency principles, the TCosy system transforms houses and delivers the following benefits for the council and their tenants:
