The new minimum standard for homes is based on the Code for Sustainable Homes’ level 3 requirements and the Building Research Establishment’s assessment scheme for other buildings.
Environment, Sustainability and Housing minister Jane Davidson said: “The policy focuses on carbon reduction where both renewable energy technologies such as solar panels; and low carbon sources such as combined heat and power schemes; can help reduce the carbon footprint of new developments in Wales.”
Ms Davidson also announced the launch of an advice booklet to help householders improve the energy efficiency of existing homes and help cut fuel costs.
The booklet, which is titled “Improving your Home – A Climate Change Guide”, includes information on 10 common projects that can be undertaken to improve a house.
She added: “For example, when a householder is thinking of adding an extension to their home I want to encourage them to think about the orientation of the extension to reduce carbon emissions, and also to think about the materials that they use to ensure they are resilient to flooding.”
