Display Energy Certificate (Example Below)

Asset Rating
Operational Rating

 

Asset Rating - 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. The asset rating will affect your business, this is the key indicator of how energy efficient your business premises is to potential clients.
Operational Rating - 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.

 

What buildings will be affected by the introduction of DEC's?

Only buildings occupied or part occupied either by a public authority or an institution providing a public service to a large number of persons and who are therefore frequently visited by those persons (referred to as relevant institutions), and with a total useful floor area greater than 1000m2 are affected by this legislation.

Private sector owned buildings do not require a DEC. Although the scheme may be extended to include the commercial sector in the future.
