Thermal Performance - Part L

Independent research has shown that rooflights make a positive contribution to compliance with Part L of the Building Regulations. Full Guidance on use of Rooflights to help meet these requirements is given in NARM document NTD06.2 “Designing with Rooflights - Supporting Part L Building Regulation guidance in England; Approved Documents L1A, L1B, L2A and L2B (2013 editions)”, which is a second tier document referenced from Approved Document L, and approved by the Department for Communities and Local Government.

NARM has also commissioned Elmhurst Energy to undertake analysis into energy savings and emissions reductions resulting from improving daylighting and lighting controls on specific building types. The document entitled "Analysis of Improving Daylighting and Lighting Controls on a Number of Existing Non-Domestic Buildings" can be downloaded here.
