[edit] Energy Performance Certificates
Energy Performance Certificates (EPCs), set out the energy efficiency rating of buildings from A (most efficient) to G (least efficient) and are valid for 10 years. 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. An EPC contains information about a property’s energy use and typical energy costs and recommendations about how to reduce energy use and save money.
[edit] Energy Performance Contracts
Energy Performance Contracts are also referred to as EPC’s but are contracts for the implementation of energy saving and renewable energy measures by a contractor, sometimes referred to as an Energy Service Company (ESCo) or EPC provider. They first emerged in the US in the 1970s and 1980s. They can be appropriate for domestic and commercial properties, but are most often associated with public-sector clients.
