Features
The Simple Economic
Tool is for quick and simple electricity savings-only analysis on your phone, tablet, or laptop.
Analysis
The Simple Economic Tool allows users to compare a baseline system (existing, or new install) to one proposed alternative.
You can then view several 1st level analysis metrics, such as simple payback and cost of waiting.
You can now estimate the savings from lighting controls in the simple economic tool. Click 'Show Controls' and then enter in the quantity of controls, estimated reduction factor, e.g. 25%, and a cost per control. The additional savings
will reduce annual cost and typically also reduce simple payback. You can toggle controls on and off by clicking 'hide controls' which will collapse the fields and remove controls from the calculation.
For more complete and detailed economic analysis, use the Visual Economic Tool.
