The Energy Performance of Building Directive…

The principal objective of the directive is to promote the improvement of energy performance of buildings through cost-effective measures.

This includes:

  • A methodology for calculating the energy performance of buildings;
  • Setting minimum energy performance requirements for new and existing buildings;
  • Energy Performance Certificates are needed whenever buildings are constructed, sold or leased;
  • Inspections of boilers and air-conditioning systems;

CMR building energy services consultants work with clients to ensure cost effective support in achieving compliance with the EPBD of the current building regulations.

Energy Performance Certificate (EPC)

These certificates are required by law for domestic and non-domestic and consists of an audit of the buildings shell structure to ascertain its energy efficiency. This audit includes:

  • Asset rating for the building’s energy efficiency through a range of bands from A-G;
  • Energy performance information for the prospective purchaser or tenant;
  • Allows a comparison of the potential energy efficiency of one building with another;
  • The accompanying recommendation report lists cost effective and other measures to improves the energy rating.

Part L

Part L is the section of building regulations which deal with energy efficiency and fuel conservation. Both domestic and non-domestic buildings must comply with Part L to be approved for construction. Buildings that must comply with Part L have to be recreated in a computer model to verify if the building as design and as built have lower carbon emissions against a notional building that sets the minimum energy standard necessary for compliance.

DECs

Public buildings which have a total useful floor area over 250m2 must display a Display Energy Certificate (DEC). The DEC summarises energy related information about the building to increase the awareness of the building occupants about the building energy efficiency. If the building floor area is between 250 and 999m2 the DEC is valid for 10 years. For buildings with a floor area over 1000m2 the DEC is valid for 12 months. The certificate is also accompanied by a set of energy efficiencies recommendations which are valid for 7 years for building over 1000m2 and 10 years for buildings below this threshold. Differently from the EPC, the DEC are produced upon the actual building energy usage but as per the EPC, the DEC certificate ranks the building to an energy efficiency scale from A to G, with A being the most efficient and G the least.

AC Inspections

Air Conditioning systems in private and public sector buildings need to be maintained and managed to ensure efficiency. Air Conditioning (AC) inspections have become statutory requirement under the Energy Performance Buildings Directive (EPBD) as part of the UK government’s initiative to improve energy efficiency and reduce carbon emissions.

How can CMR help?

In addition to the report outlining specific measures that should be taken to improve the building’s efficiency, CMR will also provide an accompanying advisory report identifying poor assets and how these assets should be modified or replaced e.g.through bespoke physical recommendations and the implementation of building controls and building energy management systems (BEMS).
These studies can help identify the potential for huge carbon and financial savings through the sourcing, sizing and implementation of one of our proven energy efficient technologies, working towards a long-standing energy saving partnerships.
CMR has a highly-experienced team of qualified energy assessors, accredited to carry out AC inspections under the Energy Performance of Buildings Directive.
