The communities department’s claims that average commercial property buildings almost meet energy regulations have been questioned by energy assessors, Building has reported
The department found the average building was rated ‘C’ on its Energy Performance Certificate (EPC) scale of A-G, a result that has been queried by one reviewer.
Matt Fulford, head of sustainability at assessment service provider, EC Harris, said: "I’d treat this with huge caution. I’d still expect most buildings to get an E or an F."
He believes many of the commercial property buildings assessed were newly built, which resulted in improved scores.
By October 2008, all commercial property, whenever sold, built or rented will require an EPC.
The certificates are produced by accredited energy assessors and were first introduced as part of controversial Home Information Pack regulations.
The communities department has said new Display Energy Certificates (DECs), will also be required for larger public buildings "enabling everyone to see how energy efficient our public buildings are".
