Modelling a New Domestic Energy Efficiency Metric

Tender description

6. The objectives of this research are as follows: A. To identify two possible options for a new ‘energy efficiency’ metric as set out in paragraph 5 (A & B), and indicate if any SAP/RdSAP changes are required. This research should consider possible variables that could be used for 5B (Fabric Energy Efficiency metric) and advise SG on this in the interim stage 1 report. SG will then take a decision on which one we want tender to take forward for full modelling (see para 7). For each of options A & B, the research must: B. Quantify the modelled values in each metric, in kWh per m2 or other appropriate unit, for each record level dwelling in a suitable housing stock profile dataset. C. Produce new EPC ratings for each metric, to include but not limited to: develop a calculation to convert each metric value into an EPC rating on scale (1-100); investigate options for banding the new scale (linear, exponential); and investigate how to translate the new scale from the current EER scale. The outputs of objective B could be used to set a suitable upper and lower bound for each revised EPC band. D. Estimate the costs and attainability of retrofitting existing dwellings to achieve a higher standard of energy efficiency, using this new metric and scale to identify the energy efficiency measures required to reach an equivalent standard. 6.
