Green light for home energy rating software

The software used to calculate the energy performance of buildings has been approved as the UK prepares to implement energy ratings for homes sold across England and Wales.

Energy Performance Certificates are to become compulsory for all homes on the English and Welsh housing markets by 1 June.

Inspectors who gather information about the energy efficiency of home heating, hot water and electricity systems will use the software package to turn the data into a single energy rating on a scale from A to G, A being the most efficient, carbon-neutral properties.

Ratings will be accompanied by guidance on how to improve energy efficiency, cutting down fuel bills and CO2 emissions.

Brian Scannell, managing director of National Energy Services (NES) which will operate the energy ratings scheme, said: “NES invented energy ratings for homes over 17 years ago and has been producing software for energy efficiency professionals ever since.

“We helped develop the RDSAP energy rating methodology and the technical basis for the Energy Performance Certificate, so it is fitting that our software should be the first to be used to produce EPCs on 1 June – the day Home Information Packs become mandatory.”
