The code for sustainable homes (CSH) - A summary of how the code works (Version 4)

TRADA image

Although the Code for Sustainable Homes (CSH) is not a regulatory requirement for the Building Regulations, it is arguably going to have at least the same level of impact on dwelling.

Effective in England only from April 2007, the Code is the only over-arching tool which will be used to set sustainability standards for those seeking government funding through the Housing Corporation.

This Construction Briefing offers readers an overview of the code including how the code functions, details of the nine categories on which the code is calculated and the criteria that a build must achieve to obtain a 'zero carbon home' status, or one of the other star ratings.

This sheet also seeks to explain the importance of having a code for sustainable homes as a way of reducing the construction industry's carbon emissions.
