The Code for Sustainable Homes (CSH) is an environmental assessment method for rating and certifying the performance of new homes based on BRE Global’s EcoHomes scheme. It is a Government owned national standard intended to encourage continuous improvement in sustainable home building.
Scope and Scoring
The CSH covers nine categories of sustainable design:
Energy and CO2 emissions (M)
Surface Water Run-off (M)
Health and Wellbeing (M)
There are mandatory performance requirements in 6 categories (denoted by an M above). All other performance requirements are flexible. It is possible to achieve an overall level of between zero and six depending on the mandatory standards and proportion of flexible standards achieved.
