Display Energy Certificates
The purpose of the Display Energy Certificates (DECs') and Advisory Reports (AR) for public buildings is to promote the improvement of the energy performance of buildings, to raise public awareness of energy use and to inform visitors to public buildings about the energy use of a building. It forms part of the final implementation in England and Wales of the European Directive 2002/91/EC on the Energy Performance of Buildings. The specific legislation is "The Energy Performance of Buildings (Certificates and Inspections) (England and Wales) Regulations 2007 SI 2007/991, amended by SI 2007/1669, SI 2007/3302 and SI 2008/647"
The requirement for DECs' comes into force on 1 October 2008 for public authorities and institutions providing public services to a large number of people that occupy buildings (or parts of buildings that have been designed or altered to be used separately) where the total useful floor area of the building (or part that has been designed or altered to be used separately) exceeds 1000m2 and which is frequently visited by the public.
A Display Energy Certificate shows the energy performance of a building based on actual energy consumption as recorded annually over periods up to the last three years (the Operational Rating). The DEC also shows an Asset Rating for this building if this is available (by way of an EPC). A DEC is valid for one year and must be updated annually.
The Operational Rating (OR) is a numerical indicator of the actual annual carbon dioxide emissions from the building. The various types of energy consumption from occupying a building must be brought together on a common basis so that the performance of one building can be compared with that of another. The UK has decided that the common unit should be CO2 emissions, since this is a key driver for energy policy.
This rating is shown on a scale from A to G, where A is the lowest CO2 emissions (best) and G is the highest CO2 emissions (worst). Also shown are the Operational Ratings for the previous two years; this provides information on whether the energy performance of the building is improving or not.
