Energy certificates for buildings


[edit] Introduction

The EU Directive on the energy performance of buildings was adopted in 2002. It was intended to improve the energy efficiency of buildings, reduce carbon emissions and reduce the impact of climate change.

The requirements were originally introduced in England and Wales by the Energy Performance of Buildings (Certificates and Inspections) (England and Wales) Regulations 2007. Implementation in England and Wales was completed on 1 October 2008. Energy performance is a devolved matter in Scotland and Northern Ireland.

A recast of the Energy Performance of Buildings Directive was adopted in 2010 and on 9 January 2013, the Energy Performance of Buildings (England and Wales) Regulations 2012 took effect. This consolidated and revoked all previous regulations.

The regulations require that:

[edit] Energy performance certificates

Energy performance certificates (EPC's), set out the energy efficiency rating of buildings. They are required when buildings are built, sold or rented if they have a roof and walls and use energy to condition an indoor climate. If a building contains separate units (for example a block of flats), each unit needs an EPC, but they are not required for shared bedsit type accommodation.

Buildings are rated from A to G on EPC's, with A representing a very efficient building and G a very inefficient building.

For more information see Energy performance certificate.

[edit] Display energy certificates

Display energy certificates (DEC's) show the energy performance of large, public building based on their actual energy consumption. They are intended to raise public awareness of the energy use of buildings.

Buildings are rated from A to G on DEC's, with A representing a very efficient building and G a not very efficient building. DEC's should be displayed prominently in a place visible to the public.

See Display energy certificate for information.

[edit] Air conditioning inspections

The regulations require that air conditioning systems with an effective rated output of more than 12kw are inspected every 5 years. An inspection report is then produced providing information about the efficiency of the system and advice about how to improve it. There is no requirement to act on the recommendations.

See Air conditioning inspections for more information.
