A building energy rating (BER) is a energy performance certificate. It is used in Ireland when selling and constructing buildings.
The building energy rating label is an energy label rating. The label has a scale of A-G, with A-rated buildings the most energy efficient and G the least. In relation to dwellings, the Sustainable Energy Authority of Ireland states that a "BER is an indication of the energy performance of a home. It covers energy use for space heating, water heating, ventilation and lighting calculated on the basis of standard occupancy." The label is similar to the energy rating label for a household electrical appliances (examples of which include the U.S. EnergyGuide, the European Union energy label, and the Australia/New Zealand energy rating label).
A BER assessment and certificate may be compulsory to sell a building or shortly after its construction. Methods of calculations and legislations related to BER may be different from one country to another. BER was created as a tool to help monitoring and improving the overall building energy efficiency.
BER in Ireland
In Ireland, each new dwelling built from January 1, 2007, required a BER, unless planning application was lodged prior to December 31, 2006. From January 1, 2009, it became illegal to offer a dwelling for sale without BER. From July 1, 2008, a BER is necessary for new non-residential buildings where planning permission is required. From January 1, 2009, a BER is required for existing non-residential buildings, when offered for sale or to let. From 1 January 2019, a minimum BER of A2 has been required for all new residential buildings.
