Code for Sustainable Homes
A government owned standard/environmental method to reduce carbon emissions and create new homes that are more sustainable by rating and certifying against a set of criteria.
A voluntary standard which exceeds current building regs and aims to promote holistic sustainable design of new homes using a 1-6* rating system. Originally level 6 defined zero carbon, currently under consultation.
The Code for Sustainable Homes (the Code) is the national standard for the sustainable design and construction of new homes. The Code aims to reduce our carbon emissions and create homes that are more sustainable. It applies in England, Wales and Northern Ireland. It is entirely voluntary, and is intended to help promote higher standards of sustainable design above current Building Regulations minima.
The Code measures the sustainability of new homes against nine categories of sustainable design, rating the 'whole home' as a complete package. It covers energy/CO2, water, materials, surface water runoff (flooding and flood prevention), waste, pollution, health and well-being, management and ecology.
The Code uses a one to six star rating system to communicate the overall sustainability performance of a new home against these nine categories. The Code sets minimum standards for energy and water use at each level and, within England, replaces the EcoHomes scheme, developed by the Building Research Establishment (BRE).
