SPR,working with RED Sustainability Consultants, was commissioned to prepare iterative drafts of a new Technical Note for NatHERS for Existing Homes assessors.
An in-home version of the National House Energy Rating Scheme (NatHERS) rating tool – now known as AccuRate Enterprise – has been under continuous development and refinement for a number of years, ahead of an expected national launch in 2025. A draft Technical Note was required early in this process to detail, in a practical manner, the changes expected to be embodied in the in-home rating tool. This iterative, mark-up approach – which was sustained for around two years – highlighted the exact changes proposed to be made, and this enabled consultation with key stakeholders, and feedback from professionals in the field. This input was of considerable value to the program, helping to refine the final form of the in-home rating tool.
