What you can learn from Energy Performance Certificates

All domestic and commercial buildings in the UK available to rent or buy must have an Energy Performance Certificate. The Certificate provides details on the energy efficiency of a building, gives it a rating from A (very efficient) to G (inefficient), and tells you what you can do to improve that rating. It is valid for 10 years.

An EPC lets the person who will use the building know how costly it will be to heat and light, and what its carbon dioxide emissions are likely to be.

In the Teignbridge area EPCs have been issued for more than 37,000 of around 54,000 dwellings. Nearly two-thirds of these (62% or 23,137) are rated D or worse, with just 58 rated A. Only 27 dwellings have zero or negative carbon emissions, but of those, 10 are new estate houses built by Redrow in Kingsteignton. This shows it can be done so why aren’t all new build estate houses zero carbon? Most have a B or C rating.

Total emissions from dwellings rated D or below currently amount to 127kt of CO2, against 31kt for the higher rated ones.

The top recommendations in Teignbridge EPCs for improving energy efficiency are to install: solar panels (29,642 certificates), solar hot water heating (26,591), low energy light bulbs (24,075), a new condensing boiler (11,994). There are also various insulation recommendations.

If all the suggested improvements were carried out, only 5,949 dwellings  (16%) would be rated D or worse and emissions per dwelling would drop by nearly half, from 4.23 tonnes to 2.37 tonnes. But those low rated dwellings would still account for around a third of CO2 emissions.

EPC data is a useful starting point for Parish and Town councils that have declared a climate emergency. It will help to set carbon targets and implement initiatives designed to reduce emissions.  For more details, and maps showing current and potential CO2 emissions by parish, please visit https://actionclimateteignbridge.org/index.php/energy-performance-certificates-epcs/
