Improving Energy Efficiency of Facilities

The Indiana Department of Transportation (INDOT) has entered into an agreement with the Purdue University Manufacturing Extension Partnership (MEP) to perform energy assessments on six sites. The six sites were selected to represent a variety of types of buildings typical for INDOT's portfolio. These include the Research and Development Building in West Lafayette, the Crawfordsville Administration Building, the Falls City Sub District, the Greensburg Unit, the Frankfort Sub District Building, and the Central Materials and Testing in Indianapolis. This energy assessment report identifies, evaluates, and prioritizes energy-saving projects. Purdue MEP provided a comprehensive energy assessment of each site, and many energy efficiency measures (EEMs) were identified, with the potential to save in annual energy costs. We also researched available incentives from local utilities and calculated the payback period for each EEM. As a result of the assessments, six reports have been generated in order to:*Provide a benchmarking analysis to show energy performance relative to similar buildings*Provide insight into the historical energy usage patterns of the facility*Present recommended energy efficiency measures (EEM) for consideration*Provide analysis to determine first order approximate costs and savings for each EEM*Discover opportunities for incentives that may be available to help fund energy improvementsIn collaboration with the energy assessments, Purdue MEP worked with INDOT to provide instruction and facilitation in the Energy Star Portfolio Manager tool.
