Passfield Drive: Retrofit for the Future
Funded by the Technology Strategy Board and implemented in collaboration with Southern Housing, the aim of this social housing retrofit by bere:architects, was to show that deep-energy cuts are possible with social housing stock. The project, which was modelled using Passivhaus Planning Package, also demonstrated how improved thermal comfort, reduced energy bills and lower CO2 emissions are possible for millions of people in existing houses.
The mid-terraced home in London was retrofitted using a combination of external thermal insulation, Passivhaus triple glazing, continuity of insulation and excellent airtightness. The project has a predicted space heating demand of 25 kWh/m2/year and has resulted in a very comfortable, healthy indoor environment that is warm in winter, cool in summer, and has plentiful high quality indoor fresh air all year round.
21° supplied, designed and commissioned the MVHR (heat recovery ventilation) system on the project. The system specified was the PAUL Novus 300 MVHR system, using a PAUL ISO Frost Protection controlled by the UST Bus Thermostat.
