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.
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.
