A **Building Energy Rating** (**BER**) is an [energy performance certificate](/source/Energy_performance_certificate) used in [Ireland](/source/Republic_of_Ireland) when selling and constructing buildings.

## Description

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](/source/Efficient_energy_use) and G the least. In relation to dwellings, the [Sustainable Energy Authority of Ireland](/source/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](/source/Water_heating), ventilation and lighting calculated on the basis of standard occupancy."[1] The label is similar to the energy rating label for a household [electrical appliances](/source/Electrical_appliance) (examples of which include the U.S. [EnergyGuide](/source/EnergyGuide), the [European Union energy label](/source/European_Union_energy_label), and the Australia/New Zealand [energy rating label](/source/Energy_rating_label)).

## Use

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](/source/Efficient_energy_use).

### BER in Ireland

The [Statutory Instrument](/source/Statutory_Instrument) regulating the requirements for BER is "*S.I. 666 of 2006*". It is Ireland's implementation of the [directive on the energy performance of buildings](/source/Directive_on_the_energy_performance_of_buildings).

In Ireland, each new dwelling built from January 1, 2007, required a BER, unless [planning application](/source/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](/source/Planning_permission) is required. From January 1, 2009, a BER is required for existing non-residential buildings, when offered for sale or to let.[2] From 1 January 2019, a minimum BER of A2 has been required for all new residential buildings.[3]
