Abstract
There is now clear evidence of a gap between the designed and as-built energy performance of new homes.
This gap can arise in a number of ways within the overall house-building process and, if significant and widespread, represents a number of risks to government, industry and consumers.
In February 2011, a Zero Carbon Hub task group, having reviewed historical research1 and gathered further industry evidence, advised that future performance standards for zero carbon homes should be linked to ‘as-built’ perfor- mance to achieve the '2020 Ambition’.
In response to this challenge the Performance Gap project commenced at the start of 2013, bringing a wide range of participants together to establish a better understanding of the Performance Gap and to formulate any necessary solu- tions. The initial activities and findings are detailed in the Interim Progress Report, published in July 2013.2
