United Welsh Housing Association
These two homes built in Ebbw Vale, South Wales, are designed to achieve exemplary energy use. They were built to show that it is possible to build social housing that meets the demanding Passivhaus standard. Pendragon (Design & Build) were the first UK construction company to build a zero carbon Passivhaus.
The two dwellings use slightly different approaches to achieve Passivhaus standards, with one based around peak heat loads, and the other around annual heat demand. This provides a useful comparison of the approaches, which has not been possible elsewhere. Like other Passivhaus homes, they both have mechanical ventilation with heat recovery, extremely good insulation, airtightness and high performance glazing.
