BER Certification

Denis O'Sullivan & Associates (DOSA), Consulting Engineers provide a comprehensive service in the area of preparation and submission of Building Energy Rating Certificates.

Building Energy Rating

A Building Energy Rating (BER) is a standard calculation of the energy performance of a building. The BER is calculated by a qualified assessor using the DEAP software approved by the Sustainable Energy Authority of Ireland (SEAI).

A BER Certificate is very similar to the new CO2 emissions rating of a motor vehicle or the energy consumption rating for household electrical appliances.

A BER Certificate is based on the primary energy demand for the building and ranges from ā€œA1ā€ (most efficient) to ā€œGā€ (least efficient).
