What is a BER Certificate?

A Building Energy Rating (BER) is an indication of the energy performance of a building. It covers energy use for space heating, water heating, ventilation and lighting, calculated based on standard occupancy. It is expressed as primary energy use per unit floor area per year (kWh/m2/yr). “A” rated properties are the most efficient and will tend to have the lowest bills. It is calculated using software developed by the Sustainable Authority of Ireland.
