Energy Savings Calculations

EnergyTracer has two methods of energy savings calculations: weather normalized savings and simple savings. 

Simple savings is used if no regression model is created and assigned to a building and is just the difference in the current month's data minus its corresponding month's data in the baseline period. 

Weather normalized savings used a regression model that is generated on the analysis page and is assigned to a project. This model uses baseline energy and weather data to create an expected energy model. This model is then used on weather conditions in the current performance month to find the expected or adjusted baseline energy value then this value is subtracted from the actual energy usage that month.
