Research undertaken by the LSI has been fundamental in establishing the concept of the “performance gap” which is now ubiquitous in building energy efficiency policy. Our research has not only led to changes to Part L of the Building Regulations for England and Wales, but it has also established building performance evaluation (BPE) as a major focus for research council, government and industry funding.

One of the greatest impacts of the LSI research has been to provide empirical evidence that the party wall bypass could be responsible for a significant amount of heat loss and was contributing to the discrepancy between the predicted and measured heat loss of new dwellings, often termed the building fabric thermal ‘performance gap’. This work directly led to changes to Part L of the Building Regulations, and established cavity party wall insulation in UK domestic retrofit policy – potentially a multi-million-pound insulation market.
