What are BERs?

BER indicates the energy rating of a building. The BER rating is determined in the form of performance bands, “A” being the most efficient to “G” being the least energy efficient.

At Green Energy Building Services, Laois, we provide assistance to homeowners, developers, builders and landlords by helping them apply for and receive grants towards the costs incurred for upgrading the energy efficiency of their property.

The Dwelling Energy Assessment Procedure (DEAP) will determine your property’s Building Energy Rating (BER) within a scale from most efficient A1 right down to least efficient G.

A BER certificate displays the energy performance of a building, that is, the energy used per square metre per year (kWk/m²/yr).

A dwelling built to the current standards would typically receive a C1 rating at best, meaning a dwelling consumes between 150-175 kWk/m²/yr of energy. However changing requirements mean that homes for which planning permission is applied for on or after 1 July 2008, will typically achieve a B1 rating. Achieving a B1 rating will reduce energy consumption to between 75-100 kWk/m²/yr almost half the usage of a C1 rated home.

From 2009 a BER certificate will need to be produced for all homes being sold or rented. This will allow prospective buyers and tenants to compare the energy efficiency of your home against others and take energy performance into consideration when deciding what home to purchase or rent.
