<p>Energy Efficiency and Carbon Reduction in Housing</p>

In this article, John Dodd, technical manager at Marley Eternit, discusses how using a combination of measures across the building envelope can achieve significant improvements in both carbon emissions and energy efficiency in existing housing stock.

As the UK edges closer to its 80% carbon reduction target by 2050, existing buildings are coming under increasing scrutiny as one of the main producers of CO2 emissions. Many existing properties in the UK were built before building regulations were extended to consider energy use. While many will have had some energy efficiency improvements, significant potential for further savings remains.

By installing a number of different roofing, cladding and insulation measures it could be possible to reduce the carbon emissions of existing properties by as much as 30%. This estimate is based on a 1920s three bedroom terraced house being refurbished with exterior wall insulation and rainscreen cladding, fibre cement roof slates and loft insulation, integrated photovoltaic roof slates, as well as work on doors and windows to improve air tightness.
