Energy Performance of Buildings

The Energy Performance of Buildings Directive aims to reduce the amount of energy consumed by buildings in order to reduce carbon emissions.

The energy performance of a building is defined as the amount of energy actually consumed (or estimated to be necessary) to meet the different needs associated with a standard use of the building including heating/cooling, lighting and provision of hot water.

The Directive is transposed via the Environment (Energy Performance of Buildings) Regulations 2012 and it requires all buildings (as defined by the Directive) to receive an Energy Performance Certificate when constructed, rented or sold. It also requires all new buildings and major refurbishments of existing buildings to achieve a minimum energy performance standard; public buildings to obtain a display energy certificate and all new buildings to consider alternative energy systems prior to construction.

This legislation is implemented by the Department of the Environment in collaboration with the Town Planning and Building Control departments.
