One week left to feed into DECC Green Deal in use factor study

Department of Energy and Climate Change (DECC) is asking for industry help in assessing the impact of its Green Deal home energy efficiency improvement initiative. It wants the supply chain – and the wider housing industry – to provide evidence by 5 November of real-life performance of energy efficiency measures available to UK housing under the Green Deal and Energy Companies Obligation (ECO) initiatives.

Bristol-based resource efficiency consultancy Sustain is leading the review, with partners Eunomia Research and Consulting and The Centre for Sustainable Energy.

The review will assess the in use factors (IUFs) used to calculate energy savings under the two policies. They are used to account for the differences in performance of energy efficiency measures in real life compared to laboratory testing. In reality, performance is often lower than when modelled in SAP or RdSAP. Imperfect installation and poor maintenance are key factors taken into account.

Results of the review are expected next spring.
