WHAT IS A DISPLAY ENERGY CERTIFICATE?
From 1 October 2008 Display Energy Certificates have become a statutory requirement for public buildings with a total useful floor area
exceeding 1,000sqm which are regularly visited by a large number of people and are occupied (or part occupied) by either:
A Public Authority - which includes local and national governments, NHS Trusts, MOD, schools and universities, executive agencies and
regulatory bodies;
A body that provides a public service - including services provided by local or national governments.
DECs must be carried out by a qualified energy assessor.
Display Energy Certificates (DECs) will be required for many public buildings from 1 October
2008 as part of the final implementation of the European Directive 2002/91/EC on the
Energy Performance of Buildings in England and Wales.
WHAT IS DEFINED AS A BUILDING?
A building is defined as “a roofed construction having walls for which energy is used to condition the indoor climate” and a reference to a
building includes a reference to a part of a building, which has been designed or altered to be used separately. This means that if part of a
building is occupied by a Public Authority or institution providing a public service, which exceeds 1,000 sq.m and is regularly frequented by
a large number of persons then that part of the building occupied will require a DEC.
The three types that come under the DEC umbrella:
A. It is a public building;
B. Exceeds a total useful floor area of 1,000 sq.m; and
C. Frequented by the public
WHAT IS A DISPLAY ENERGY CERTIFICATES?
A DEC provides a visual energy performance rating based on actual energy consumption recorded annually. A DEC is valid for one year and
must be updated annually. Each DEC has an Operational Rating (OR), which is a numerical indicator of the actual annual carbon dioxide
emissions from the subject building. Various criteria are employed to ensure that the energy performance of one building can be compared
with that of another. A building is given a rating on a scale from A to G with A being the lowest CO2 emissions and G being the highest CO2
emissions. ORs from previous years are also displayed on the Certificate to show the changes in the building's energy performance. An OR
of 100 is the Government benchmark, which is a typical energy consumption for that type of building. The OR is produced using a software
tool made available by the Government called the Common Information Point (CIP) by an accredited energy assessor to calculate the CO2
emissions.
WHAT IS AN ADVISORY REPORTS?
From 1st October 2008 buildings are also required to have an Advisory Report (AR), which is valid for seven years. The AR is a list of short,
medium and long term alterations that can be made to the existing building to reduce total CO2 emissions. Although recommendations
within the AR are not required by law to be implemented if the recommendations are followed, the total CO2 emissions will be reduced
and long term savings can be made. The energy assessor can also include additional item that he/she believes will aid in reducing CO2
emissions at the end of the AR in addition to those selected by the assessor from the list produced by the software.
REQUIRED DATA TO PRODUCE A DEC?
Energy meter readings for the last 15 months, floor areas, and details of the building and energy services. All relevant information is then
entered into the approved software program, which is regularly updated and the DEC and AR are then produced. If the occupier of the
building cannot provide meter readings or floor areas, the energy assessor will be required to contact the main energy suppliers to obtain
actual meter readings and will carry out a measured survey of the building to confirm total floor area. This will necessarily result in greater
time being spent in producing the DEC, which will have an implication on the fees charged. The completed DEC and AR are lodged in a
national register and given a unique certificate reference number, which is detailed on the DEC and can also be found on www.
ndepcregister.com. The DEC will need to be displayed in a prominent and clearly visible place in all relevant buildings.
