The implications of poor building details extend beyond increased heat loss and associated compliance with Part L CO2 and fabric energy efficiency (FEE) standards. Where the internal surface temperature around a building detail (such as a lintel or sill) is excessively low, the risk of surface condensation is increased. This can damage surfaces and lead to mould growth which is …
