Building regulations: conservation of fuel and power

This consultation paper sets out the detailed proposals on part L of the building regulations. It is section 2 of 4 of the 2012 building regulations consultation exercise.

It includes proposals for tighter carbon dioxide emission standards for new homes and non-domestic buildings, to take the next step towards zero carbon standards, plus tighter performance standards for works to existing buildings.

The paper also contains proposals to introduce, on a phased basis, requirements for additional energy efficiency improvements to be carried out when other specified works (eg extensions) are planned and Green Deal finance is available as an option to meet the up-front costs.
