Overview
A homeowner’s typical usage is pulled based on the address. For each energy efficiency product added to the project, a percent reduction is calculated based on the percent better than the standard. The percent reduction is pulled directly from EnergyStar data on a per appliance basis. The percent reduction is applied directly to the end use consumption for the usage category directly connected to the EE product. Applying the reduction gives the post installation usage, and impact is directly shown in the usage/production charts.
