A Building Energy Rating (BER) is a measure of the energy performance of a building. It is typically used to assess and communicate how energy-efficient a residential or commercial property is. The rating is presented in the form of a certificate, and it gives an indication of the building’s energy consumption and carbon emissions.
The BER rating is expressed on a scale from A to G, with A being the most energy-efficient and G being the least. The scale is color-coded, with green for higher efficiency (A-rated) and red for lower efficiency (G-rated). Here’s a brief overview of the ratings:
In Ireland, every new dwelling and non-domestic building offered for sale or rent to any prospective purchaser or tenant must have an energy rating certificate provided by a certified BER assessor. New dwellings will typically require a Building Energy Rating (BER) of A2, compared to the current requirement of A3 for new residential dwellings. A BER certificate shows a building’s energy performance.
