Display Energy Certificates
Display Energy Certificates measure the operational energy rating of a building. They differ from EPCs, as instead of measuring efficiency based on the fabric construction of the building and installed heating and conditioning, the rating is based on actual energy consumption readings.
Currently a DEC is required only for Public Authority buildings or publicly funded buildings, from Town Halls to Schools, Hospitals to Court buildings, and only if they are more than a certain size, and are regularly visited by the public. Some believe that as the DEC is a relevant comparison to an EPC, that eventually all commercial buildings will be required to display both certificates.
The DEC is in 2 parts. The actual display certificate is a short document with a graphical illustration of the energy efficiency of the building. This is renewed annually based on up to date energy readings. The second part, the advisory report, details changes and improvements that can be made to energy use and understanding of wasteful behaviour. Suggested improvements are divided in to those that offer short, medium or long-term payback, and have low, medium or high impact on energy efficiency. The advisory report is valid for up to 7 years.
In addition to public buildings, many companies looking to gain 'Green PR' may also choose to display a DEC as a way of showing to their customers their commitment to responsible business practice.
