Buildings requiring a DEC a building other than a dwelling, which is occupied by a public body, has a total useful floor area greater than m2, and is frequently visited by the public a building other than a dwelling, which has a total useful floor area greater than m2, and is frequently visited by the public.

Using benchmarks Benchmarks are used to take local factors into consideration when calculating the DEC. Provisions are made where: The building use covers more than one building use category There is a significant climate difference between the building and the standard benchmark The use periods of the building are significantly greater than the standard benchmark Specific identified processes means that energy use is more intensive than usual for the building use category.

Consumer and Communities. Make sure to have all of these documents prepared for a quick and easy service. It depends on your building type! Display Energy Certificates DECs need to be displayed in buildings that are over m2, occupied by public authorities and frequently visited by members of the public. Examples of such buildings are:.

It is a requirement that DECs are made clearly visible to members of the public, for example, behind a front desk or building entrance.

You will also be required to commission the documents otherwise further offences would be committed. To avoid penalties, make sure to check whether you have your DEC in a visible area and that the certificate is up to date. We wish we could give you a simple answer, but it all depends on the size of the property total useful floor area.

If the building is between m2 and m2, both the DEC and advisory report will be valid for 10 years. However, if the building is more than m2 then the Display Energy Certificate will only be valid for 1 year meaning it will need to be reviewed annually. Although, the advisory report will be valid for 7 years to give you enough time to make the necessary changes to the building. Whilst Display Energy Certificates are needed all year round for public buildings, the Energy Performance Certificate EPC on the other hand, is just needed when a building is being sold, rented or constructed.

The certificate gives you proof surrounding how energy efficient your property is as well as showing any areas of potential savings on energy cost which is a bonus! Energy Performance Certificates are formed from the SAP scoring criteria and are calculated looking into areas such as construction materials, heating systems, solar gains, thermal insulation and much more. Overall, a DEC is used to show how much energy the building is actually using over a period of time.

Whereas an EPC shows the theoretical efficiency of a building. This is where we come in! Here at Buildpass, we are qualified to access your building, calculate your operational rating and provide you with a Display Energy Certificate.

We will also provide you with the advisory report and help you with the next steps on how to increase your operational ratings score — great, right? View Our Blog. In collaboration with the assessor, the occupier will be required to obtain actual meter readings or energy bills for all fuels used in the buildings that are affected by the legislation.

The accompanying advisory report is valid for 7 years. An Advisory Report is put in place to enable the occupier to identify what can be done to improve the building.

The report may contain a variety of recommendations that can be implemented in the property to help improve its energy efficiency and reduce carbon emissions.

There is no mandatory requirement to implement any of the recommendations provided. Our Energy and Carbon Consultants are fully accredited to produce DECs and Advisory Reports, making recommendations specific to your building, on how we can help you improve the energy efficiency and reduce your carbon emissions.
