Energy and Cost Savings Calculators for Energy-Efficient Products
The energy and cost calculators below allow Federal agencies to enter their own input values (such as utility rates, hours of use) to estimate energy and cost savings for energy-efficient products. Some are Web-based tools; others are Excel spreadsheets provided by ENERGY STAR® for download.
Commercial and Industrial Equipment
Food Service Equipment
Renewable Energy Installations
Additional resources are available to calculate energy savings, including FEMP Building Life Cycle Cost (BLCC) software for detailed life cycle cost analysis, Lawrence Berkeley National Laboratory's RESFEN for estimate heating and cooling costs for many house types, and MotorMaster+ software for identifying "premium" efficiency motors.
