Energy Performance Certification Service
Energy Performance Certificates for commercial buildings became mandatory within the UK through Statutory Instrument SI 2007 No.991. This implements the requirements of the EU Energy Performance of Buildings Directive (EPBD), Article 7. A Commercial EPC is intended to inform potential buyers or tenants about the energy performance of a building, so they can consider energy efficiency as part of their investment or business decision to buy or occupy a building.
The EPC provides an energy rating, called an Asset Rating, for a building, based on the performance of the fabric of the building itself and its services, such as heating, ventilation and lighting. The Asset Rating is shown in a graphical format on a scale from A (more efficient) to G (less efficient) as well as giving a numerical value.
These ratings can then be used to make comparisons with comparable properties.
The vendor/leaser has the responsibility for providing the Energy Performance Certificates with the building particulars at the time of sale or lease. These requirements are enforced by local Trading Standards Officers, who have the powers to fine vendors/leasers for non-compliance.
When an Energy Performance Certificates is provided, it is accompanied by a recommendation report, which provides recommendations on how the energy performance of the building could be enhanced, together with an indication of the likely payback period.
Energy Performance Certificates are not required on some types of building such as places of worship, those with low energy demand and those scheduled for demolition. See the DCLG website for a more detailed list of exclusions.
An EPC is not required on lease renewals or lease surrenders.
Only qualified energy assessors may carry out energy assessments and issue Energy Performance Certificates. An energy assessor must also be a member of a Government approved accreditation scheme. These schemes are responsible for registering EPCs on a national database and for ensuring the quality of EPCs produced.
Once an energy assessor has been commissioned to produce an Energy Performance Certificates, an inspection of the building is made, which together with data from drawings and other sources is used to generate an energy model for the property.
The model is created using an approved software system which takes information about the building structure, the activity for it is used and details of the installed heating and cooling system, if applicable. The software produces the Energy Performance Certificates and the Recommendation Report for the building, which is then lodged on the national register and a copy sent to the client.
