Conservation of fuel and power in new dwellings in Wales

This guide provides a starting point for designing new homes to comply with the 2014 edition Approved Document L1A – Conservation of fuel and power in new dwellings in Wales. It gives examples of some typical homes, outlining a combination of measures needed to comply with ADL1A 2014. The intention is to give a broad understanding of the specifications for masonry construction that may be adopted as a starting point for detailed design. It also illustrates the effects of thermal bridging, which can have considerable impact on the approaches to overall compliance.
