State of the nation review. Performance evaluation of new homes

Woodknowledge Wales have helped fund and support a report published by researchers at Oxford Brookes University. The report has revealed for the first time a detailed national picture of the actual performance of new build homes through a detailed analysis of building performance evaluation projects.

New-build dwellings were found to often underperform compared to actual design specifications, with energy use up to three times higher than predicted. Heat loss around openings such as doors and windows was identified as a particular problem showing a need for developers to improve detailing, specification and workmanship.
