The certificate must be displayed in a public place. It will also provide an Asset Rating & an Operational Rating on public buildings over 1000sq metres.
The Advisory Report will contain recommendations for improving the energy performance of the building and its energy usage. A DEC is valid for 12 months and needs to be updated annually. The Advisory Report which includes recommendations for improvements is valid for 7 years.
About the Display Energy Certificate
The display energy certificate differs from the domestic/commercial counterpart in that the certificate incorporates an Asset Rating & Operational Rating, DEC's are only issued for Public Buildings at this time:-The Advisory Report may specify recommendations to improve the energy efficiency and reduce CO2 emissions, the asset owner must retain possession of the report. Currently, it is not mandatory to comply with the recommendations made in the advisory report.
Means a numerical indicator of the amount of energy estimated to meet the different needs associated with a standardised use of a building, calculated according to the methodology approved by the Secretary of State.
Means a numeric indicator of the amount of energy consumed during the occupation of the building over a period of 12 months unless:
Where on 4th January 2009: the occupier of a building has been in occupation for less than 15 months or, entered into occupation of the building before 6th April 2008; or entered into occupation on or after that date but did not have an energy performance certificate made available or given to it. In these cases the operational rating specified may be calculated over the period in which the occupier has been in occupation.
Failure to Display
DEC's - The penalty is £500 for failing to display a DEC at all times in a prominent place clearly visible to the public and £1,000 for failing to have possession of a valid advisory report. A maximum fine of £5,000 may be imposed dependent on the nature of the breach of regulations.
EPC - Energy certificates rate the energy performance of a building
DEC - Display Energy Certificates (DECs) show the actual energy usage of a building, and it's Operational Rating, and provide information to the public for the energy efficiency of a building.
Many buildings will be affected by the introduction of Commercial Energy Certificates and the issue of the display energy certificate, these include:
- DEC for Public Institutions
- DEC for Government Buildings
- DEC for Local Authority buildings
