ROI of energy efficiency is the combined savings acquired from energy efficiency improvements, including reduced energy usage, lowered maintenance costs, and improved productivity.
ROI is simply calculated by subtracting the total costs from the anticipated savings, then dividing them by the total costs and multiplying by 100 (for a percentage).
Using Accruent’s Observe Energy Management (AOEM), your energy efficiency ROI can be calculated across a variety of industries and use cases.
