Code for Sustainable Homes
Setting a points based standard to make new housing greener and cheaper to run.
The CSH is the national environmental assessment method for new homes, based upon BRE Global’s Ecohomes standard, and contains mandatory performance levels in seven key areas, one of these being ‘energy efficiency and CO2’.
It aims to protect the environment, and reduce the use of resources, by providing guidance on the construction of high performance homes built with sustainability in mind.
In tandem with the implementation of the new Part L, the requirement from October onwards is for all new social housing schemes to be designed to Level 4 of the Code, while speculative development will have to meet Level 3. By 2016, all new homes will have to hit Level 6, that is, they must be effectively carbon neutral.
Although renewable energy has to play an increasingly large part, a highly insulated building envelope is again essential to reduce demand.
The Code for Sustainable Homes does not apply in Scotland.
