Energy Assessment Tools

The following software tools are available for download from the U.S. Department of Energy, Office of Industrial Technologies to help you identify and analyze energy system savings opportunities in your plant.

motor master+

An energy-efficient motor selection and management tool which includes a catalog of over 20,000 AC motors. This tool features motor inventory management tools, maintenance log tracking, efficiency analysis, savings evaluation, energy accounting, and environmental reporting capabilities.

fan system assessment tool (fsat)

A tool to help quantify the potential benefits of optimizing fan system configurations that serve industrial processes. FSAT is simple and quick, and requires only basic information about your fans and the motors that drive them. Using FSAT you can calculate the amount of energy used by your fan system, determine system efficiency, and quantify the savings potential of an upgraded system.

air master+

Provides comprehensive information on assessing compressed air systems, including modeling, existing and future system upgrades, and evaluating savings and effectiveness of energy efficiency measures.

chilled water system analysis tool

Use this tool to determine energy requirements of your system and to evaluate opportunities for energy and costs savings by applying improvement measures. Provide basic information about an existing configuration to calculate current energy consumption, and then select proposed equipment or operational changes for comparison. The results of this analysis will help you quantify the potential benefits of chilled water system improvements.

combined heat and power (chp) application tool

Helps industrial users evaluate the feasibility of CHP for heating systems such as fuel-fired furnaces, boilers, ovens, heaters, and heat exchangers. It allows analysis of three typical system types: fluid heating, exhaust-gas heat recovery, and duct burner systems. Use the tool to estimate system costs and payback period, and to perform "what-if" analysis for various utility costs. The tool includes performance data and preliminary cost information for many commercially available gas turbines and default values that can be adapted to meet specific application requirements.

pumping system assessment tool (psat)

Helps industrial users assess the efficiency of pumping system operations. PSAT uses achievable pump performance data from Hydraulic Institute standards and motor performance data from the MotorMaster+ database to calculate potential energy and associated cost savings.

process heating assessment and survey tool (phast)

Provides an introduction to process heating methods and tools to improve thermal efficiency of heating equipment. Use the tool to survey process heating equipment that uses fuel, steam, or electricity, and identify the most energy-intensive equipment. You can also perform an energy (heat) balance on selected equipment (furnaces) to identify and reduce non-productive energy use. Compare performance of the furnace under various operating conditions and test "what-if" scenarios.

steam system tool suite

In many facilities, steam system improvements can save 10% to 20% in fuel costs.  The following tools can help identify steam system savings opportunities.

steam system scoping tool

This tool is designed to help steam system energy managers and operations personnel perform initial self-assessments of their steam systems. This tool will profile and grade steam system operations and management. This tool will helps evaluate steam system operations against best practices.

steam system assessment tool (ssat)

Allows steam analysts to develop approximate models of real steam systems. Using these models, you can apply SSAT to quantify the magnitude-energy, cost, and emissions-savings-of key potential steam improvement opportunities.

3Eplus insulation assessment tool

The program calculates the most economical thickness of industrial insulation for user input operating conditions. You can make calculations using the built-in thermal performance relationships of generic insulation materials or supply conductivity data for other materials.
