Latest RdSAP (v9.94) update is coming soon
The Energy Performance Certificate (EPC) is the tool that the government has chosen to measurethe energy efficiency of buildings within the UK. It was first introduced to domestic dwellings for marketed sale and rental in 2008.
Over the last 11 years the Reduced data Standard Assessment Procedure (RdSAP), which is the assessment methodology behind the EPC, has been subject to a number of version changes. These changes have increased the amount of data included within an assessment of a dwelling to ensure that the EPC remains up to date with the latest industry standards and provides greater accuracy.
On the 22nd September 2019, the government has planned an update for RdSAP from version 9.93 to 9.94. Originally starting at version 9.82, this will be the seventh major update to the methodology since inception. The update will be undertaken simultaneously in England, Wales, Northern Ireland and Scotland.
Elmhurst believes that this is a positive step for the industry as RdSAP 9.94 will introduce a mechanism for new technologies that are not currently included in the published methodology, and will allow assessors to quickly check whether a dwelling already has a valid EPC. Elmhurst’s Existing Dwellings Team Leader Damien Roberts said:
“this is great news for our industry as RdSAP 9.94 provides an improved mechanism to help towards the government’s target of net zero emissions by 2050. One of the amendments presented by this latest update is the inclusion of ‘Appendix Q’ which details innovative products not currently modelled in RdSAP. ‘Appendix Q’ is already operational within SAP methodology for new build homes, and by extending this option to RdSAP, it should allow for new and innovative technologies to be recognised within energy assessments (and by extension EPCs for existing homes)”.
Elmhurst as always will keep all members updated with further details on version 9.94 and have already developed CPD events to ensure that Elmhurst accredited members remain informed of the latest changes.
