Ofgem published a consultation document on 27 May 2016 on the potential methodology to be used to calculate ”deemed scores” for measures installed under the new Energy Company Obligation (ECO) from 2017.
Deemed scores are pre-determined estimates of the cost or energy savings generated when measures are installed in certain types of properties.
Ofgem makes clear that DECC has not yet made the decision to go ahead with deemed scores in place of “bespoke scores” produced using RdSAP, but has published the consultation document early to give the sector enough time to consider the detail of the proposals.
The rationale for the possible change is policy is stated as: “A move to deemed scores simplifies the process by removing the need to collect the data required for a SAP assessment, and removes the layer of complexity associated with making the relevant measurements.”
The consultation sets out the proposed approach and is accompanied by a detailed report report on the methodology by the BRE and a list of scores by measure. The deadline for responses is 8 July 2016.
