Code for sustainable homes and the energy efficiency standard for zero-carbon homes

This consultation seeks views on changes to the code for sustainable homes in 2010, to align with changes to part L of the building regulations and the proposed approach to adopting the 2016 definition of zero carbon. Therefore, the most significant changes are within the energy section of the code.

This consultation also puts forward our proposed changes to credit issues such as lifetime homes, home security, surface water run-off and waste, as well as setting out issues that are being considered for further investigation in the future.

It also seeks views on the energy efficiency definition to be incorporated into the definition of zero-carbon homes from 2016 and whether that should be introduced into building regulations at an intermediate level from 2013.

Part A looks at changes to the code for sustainable homes and incorporates the proposed fabric energy efficiency standards being consulted on in part B of the consultation.
