Public buildings are required to have an up-to-date Display Energy Certificate (DEC) to show the energy performance of the building. Certificates are renewed annually, tracking energy use and therefore carbon emissions associated with the building.
Here’s The Plan work with accredited assessors to provide a DEC service to our clients who must comply. Certificates are renewed annually, tracking energy use and therefore carbon emissions associated with the building. The site audit establishes the potential for reducing energy consumption and identifies any areas that have an unusual energy demand for that type of building or operation.
The Regulations
From 9th July 2015 a Display Energy Certificate and advisory report is required for any building with a total useful floor area over 250m² that is occupied in whole or part by public authorities and by institutions providing public services to a large number of persons and therefore frequently visited by those persons. A DEC can only be issued by an accredited assessor and it must be registered on the national database administered by Landmark plc.
The Operational Rating (OR) for Display Energy Certificates is based on the actual energy consumption in a given 12 month period for the building and is renewed annually for buildings over 1,000 sq m and every 10 years for those below 1,000 sq m. The Advisory Report which lists potential measures that can be taken to reduce energy consumption is valid for a 7 year period for buildings over 1,000 sq m and for a 10 year period for those below 1,000 sq m and does not need to be displayed.
The Operational Rating (OR) shown on the certificate is a numerical indicator of the actual annual carbon dioxide emissions from the building and is compared to typical benchmarks for similar types of building. It is the Occupier's responsibility to display in a prominent place that is accessible to the public their Display Energy Certificate.
The Certificate has to be renewed annually which builds up a track record of how the occupier is managing the energy use and hence the carbon emission of the building.
What is involved in producing a Display Energy Certificate
The Energy Assessor will carry out a walk around survey of the building to establish what the potential for reducing energy consumption is and identify any zones that have untypical energy demand for the type of building. The energy assessor will request data about the use of the building, the total useable floor area, the operational hours, and details of any air conditioning equipment.
The Operational Rating can be influenced by a number of factors:
