Energy Efficiency Models

  • Local Energy Efficiency Policy Calculator
    he Local Energy Efficiency Policy Calculator (LEEP-C) version 2.0 Beta is intended for use by local policymakers and stakeholders interested in advancing the adoption of energy efficiency in their communities. The tool is capable of analyzing the impacts of 23 different policy types from 4 energy-using sectors: public buildings, commercial buildings, residential buildings, and transportation. It provides a first-cut, initial analysis of the impacts of policy choices on energy savings, cost savings, pollution reduction, and other outcomes over a time period set by the user. The tool also allows users to weight different policy options based on community priorities to gauge which policies best fit with community goals.
  • Energy Efficiency Benefits Calculator
    This spreadsheet based tool shows the Energy Efficiency Benefits Calculator developed for the Leadership Group of the National Action Plan for Energy Efficiency. The tool demonstrates the benefits to customers, utilities, and society of implementing energy efficiency programs, and evaluates the business case for energy efficiency universally across utility types. The tool can be calibrated to numerous applications including electricity and natural gas, public or private utilities, vertically integrated or restructured markets and various utility financial structures.
  • DOE2 Building Energy Analysis Program
    This link introduces the DOE-2 building energy analysis program which predicts the energy use and cost for all types of buildings. DOE-2 uses a description of the building layout, constructions, operating schedules, conditioning systems (lighting, HVAC, etc.) and utility rates provided by the user, along with weather data, to perform an hourly simulation of the building and to estimate utility bills. Other building energy analysis tools such as eQUEST® is also available from the link.
  • Greenhouse Gas Equivalencies Calculator
    The greenhouse gas equivalencies calculator helps translate carbon reductions into concrete terms you can understand, such as the annual emissions from cars, households, or power plants.
