What you will see in a BER Certificate
A BER Certificate assigns a rating on a scale of “A” to “G” and a color code for each rating. Each of these gradings is assigned a color code (which is indicated in the image on this page) and also a specific energy consumption level in kwh/ m2/yr. In addition BER also indicates a rating for the CO2 emissions due to your building in kg CO2 per m2 per year.
