Building Energy Ratings (BERs)
Guide to the BER
A Building Energy Rating (BER) is similar to the energy label for a household electrical appliance like your fridge. The label has a scale of A-G, also clearly distinguished by colours, green to red. A-rated homes (Green) are the most energy efficient and G-rated homes (red) the least efficient.
The calculation method used to determine Building Energy Ratings is known as the Dwelling Energy Assessment Procedure (DEAP). This is in the form of a detailed software program which takes account the energy required for space heating, ventilation, water heating and lighting less the savings from energy generation technologies.
