In recent years, the housebuilding industry and government have grown increasingly concerned over the potential gap between design and as-built energy performance. It could undermine a building’s vital role in delivering the national carbon reduction plan, present a reputational risk to the housebuilding industry and damage consumer confidence if energy bills are higher than anticipated.
In response, the Zero Carbon Hub was commissioned to review evidence for the significance of this gap, explore potential reasons for it and set out proposals to address these reasons.
The project has engaged more than 160 industry experts from across 90 companies, seeking to understand the nature of the Performance Gap and provide solutions.
