Display Energy Certs (DEC)

From the 9th January 2013 publicly and privately owned buildings over 500m2, frequently visited by the public, are required to exhibit a DEC, in a prominent place, clearly visible to the public. The DEC is intended to encourage public authorities to adopt environmentally responsible and efficient use of energy in buildings.

The DEC is based on the measured energy use, where the actual energy consumed in the building is compared to a benchmark for similar buildings, and shown on the certificate A1 – G scale in terms of primary energy. There is also a CO2 indicator which shows the CO2 emissions associated with the building’s energy consumption. Benchmark or typical buildings have a E1 rating. – See more at:
