IAC Nationally

As of July 2018, the national IAC program had conducted more than 18,000 assessments with over 130,000 associated reccomendations, saving U.S. companies more than $2.4 billion through efficiency and productivity improvements.

The Oregon State University EEC/IAC has recommended more than $500 million in annual cost savings to over 700 manufacturers, fourty-five percent of recommendations have been implemented, equaling $225 million in savings to manufacturers. The companies that implement our recommendations not only save money, but also help reduce pollution, 625 tons of CO2 a year are saved per facility on average.

 

Who Wins?

  • Industry

    Facilities who receive an assessment and implement recommendations:

    • improve process efficiency
    • reduce energy costs and waste; average energy savings are $20,000 annually and non energy savings are $98,000 annually
    • demonstrate their commitment to sustainability
  • Participating University Faculty

    Through the IACs, universities:

    • build valuable local industry relationships to maintain a practical focus in their engineering curriculum.

    • gain an edge in attracting and retaining top undergraduate and graduate engineering students.

  • Participating Students

    The next generation of energy-savvy engineers is being prepared in today's IAC program. Each year, 150 students participate nationally, gaining valuable hands-on experience that can jump-start their engineering careers:

    • collecting data on audits, making recommendations and preparing reports
    • build professional relationships with local industry
    • understand key industrial operations, systems, and processes
    • receive in-depth energy efficiency training from faculty and student mentors
  • U.S. Taxpayers

    The Department of Energy's Office of Industrial Technologies provides financial and technical support to the IACs. The nation's economy benefits from more competitive small and medium-sized manufacturers--- a sector that accounts for over 50 percent of U.S. manufacturing employment. Other returns include:

    • enhanced energy security
    • environmental benefits from decreased energy and resource use
    • highly trained efficiency professionals

 

The primary objective of the IAC is to identify and evaluate opportunities for increased productivity, energy conservation and waste minimization through visits to industrial sites.
