An Energy Performance Certificate (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 that building.
Directive 2002/91/EC of the European Parliament and Council on energy performance of buildings came into force on January 2003.
It is intended to raise awareness of energy use in buildings, and thereby influence selection by building owners and tenants, and lead to a substantial increase in investment in energy efficiency measures. The EPBD required transposition by 4th January 06, with full implementation by 4th January 09.
In England and Wales the EPC and Inspection of air-conditioning plant is being implemented through the Energy Performance of Buildings (Certificates and Inspections) (England and Wales) Regulations 2007 (SI 2007/991).
An EPC will provide an energy rating of A to G (‘A’ being the most efficient) for a building which is based on the performance potential of the building itself (the fabric) and its services (such as heating, ventilation and lighting).
It is accompanied by an ADIVSORY REPORT, which provides recommendations on how the energy performance of the building could be enhanced, together with an indication of the payback period.
