The Code for Sustainable Homes
The Code for Sustainable Homes is an assessment methodology for measuring the home and utilities as a whole. The categories assessed to measure sustainability include,
- Energy / CO2 - Assessed through SAP / Part L assessment
- Water
- Materials
- Surface water run-off
- Waste
- Pollution
- Health and well-being
- Management
- Ecology
To reach the levels in the code for sustainable homes, credits and certain values must be achieved in each category.
For category 1 (SAP) the following percentage reductions must be found against the standard pass rate TER. In reaching these targets, EPCs are also indirectly increased in value.
