The Aggregated Metered Baseline (AMB) method allows energy savings to be calculated across a group of energy customers. It allows energy savings to be calculated for an activity that is rolled out over a large number of sites and achieves relatively small savings at each site. The method uses veriﬁed statistical analysis to determine the signiﬁcance of energy savings. In this method, the term ‘energy’ may refer to electricity, gas, or both.
