SCHOOLS

EPA's TargetFinder Rating Tool

Target Finder is an online tool that can establish

energy performance goals for a project.

It uses data such as zip code and building type to

calculate the estimated total energy use for the

building, and then it assigns an energy performancerating on a scale of 1 to 100.

Energy Costs?

Annual energy costs are determined using rates for

purchased energy, such as electricity, gas, oil,

propane, steam, and chilled water, that are based

on actual local utility rates or

the state average prices published annually by the

U.S. Department of Energys Energy InformationAdministration, at www.eia.doe.gov.
