For independent evaluation and confirmation that your energy efficiency projects are providing the forecasted savings, we use a calculated baseline from regression analysis. The difference between the baseline and actual consumption after completion of the project works is measured as the achieved savings.
We also display your targeted project savings together with a CUSUM cumulated savings chart, to provide a visual and informative summary of the success of the project.
Having analysis of the savings and usage ensures credibility and can also be used to challenge contractors/providers of equipment where the expected savings are not being achieved.
