Commercial BERs (Building Energy Ratings)

Commercial BERs (Building Energy Ratings) is a rating of a building's energy performance, indicating its energy efficiency. Buildings are rated on a scale of A-G, with A-rated buildings achieving the most energy efficiency, and G-rated the least.

Commercial BERs Certification

We have several Building Energy Rating (BER) assessors who produce a building’s energy rating.

Preliminary BER Certificates can be provided using a simplified Building Energy Model which gives a quick turnaround assessment at the pre-planning stage.

For complex buildings that involve natural ventilation and complex building structures, we use integrated environmental simulation (IES) which allows a much more advanced computer simulation of the building.

In all cases, the Building Energy Rating will be accompanied by a detailed report. The report identifies building improvements and investment options for the client, to improve the building’s performance and reduce running costs.
