The UK’s first Passivhaus retrofit

Enhabit was engaged by Octavia Housing to provide engineering design and project management services for the retrofit of this solid brick Victorian terraced house in a conservation area.

Enhabit worked with builders Ryder Strategies, architects Paul Davis and Partners, energy consultants Eight Associates.

The house comes equipped with over a dozen low energy innovations including Enhabit’s Passisash windows, super wall insulation, ESE solar thermal panels and a heat exchange system that recycles energy from waste air and water. The home has no gas boiler, radiators or conventional heating system and uses these innovations to keep the house at a comfortable temperature with a healthy air-flow all year round.

The retrofit resulted in a building that is warm and comfortable without condensation or moisture problems. It now produces 85% less CO2 emissions and uses 92% less energy than before, making it the UK’s first retrofitted Passivhaus.
