On-Farm Energy Efficiency Audit Program

Purdue Extension is equipped to assit you with an energy audit for various farm operation systems. This program involves evaluating and making calculations of your existing system efficiency, and comparing it to the proposed new systems. Producers may use this audit report to apply for the USDA REAP program, or through other incentive programs facilitated by local utility companies.  Chad Martin is a Renewable Energy Extension Specialist within the Purdue Ag & Biological Engineering Department, and is a Certified Farm Energy Auditor according to ASABE Standards.  He works closely with Dr. Klein Ileleji who is the Extension Engineer for the Purdue ABE Department.  Contact us to visit further about services available for the following sectors:

  • Grain Drying
  • Irrigation Improvements
  • Dairy Farm Operations
  • Livestock Confinement Systems
  • Greenhouse Growing Facilities
  • Aquaculture Systems

Please complete the following energy audit request form and return to the Purdue Agricultural and Biological Engineering Department - Chad Martin, Renewable Energy Extension Specialist.
