What We Do

Energy in Buildings

Energy Performance Certificate (EPC)

An EPC is the reaction to the EU's Energy Performance of Buildings Directive (January 2003) requiring a reduction in the CO2 emissions of buildings. Its a means of recording a building's energy efficiency (measured in C02 emissions) on a colour-coded scale from A-G. EPCs are to be accompanied by a recommendation report containing cost effective recommendations to improve the building's energy rating, although there is no obligation to comply with these.

Display Energy Certificate (DEC)

The DEC is the outward demonstration of a public buildings energy and asset rating. They will need to be displayed in a prominent position clearly visible to the public. The DEC will incorporate an advisory report, valid for seven years, on the measures available to improve the energy rating of the public building.

The introduction of EPCs and DECs are as follows:

EPCs

• 6th April 2008 all new buildings over 10,000 sq.m new to the market.
• 1st July 2008 all buildings over 2,500 sq.m new to the market.
• 1st October 2008, the remainder (with a lower limit of 50 sq.m.) including those already being marketed.
• The EPC, once obtained, is valid for a period of ten years.

DECs

• 1st October for public buildings over 1,000 sq.m and will be valid for one year. Once obtained, the DECs will require annual renewal.
