Higher Education is Taking Energy Efficiency and Sustainability to New Heights

Eastern Illinois University is reducing its environmental impact and mitigating utility costs by pairing traditional conservation measures with one of the largest university biomass installations.

The Customer

Eastern Illinois University is a public university in Charleston, Ill. It is comprised of approximately 13,000 students and staff on a 320-acre campus.

The Problem ››

  • EIU faced a significant deferred maintenance backlog, rising energy costs, aging infrastructure and limited budget.
  • State funding for major capital projects was severely limited, making improvements difficult.
  • Honeywell Solutions ››

  • The university and Honeywell, the school’s long-time energy advisor, collaborated to identify necessary improvements and build a program to address utility bills.
  • The focal point of the program is the design of a new steam plant — called the Renewable Energy Center — drive by two large biomass gasifiers.
  • The Center will replace the university’s aging steam plant, which consumes more than 10,000 tons of coal per years and requires constant maintenance.
  • The Center, which is being built to meet LEED Gold certification requirements, also includes an instructional classroom for students in the new EIU Center for Clean Energy Research and Education.
  • Honeywell and the school entered into a 20-year energy savings performance contract, helping reduce any burden on EIU’s budget, or the need for additional taxpayer dollars or student fees.
  • Key Technologies ››

    The biomass gasifiers use wood chips sourced from the logging industry to produce biogas that burns similar to natural gas and is used to fire boilers, giving the university a carbon-neitral solution for heating all its facilities.

    Along with gasifiers, the Renewable Energy Center features a solar array and a turbine that uses high-pressure steam to produce electricity.

    Additional conservation measures on campus included retrocommissioning all mechanical systems, replacing windows, upgrading lighting fixtures, updating chilled water systems and sealing buildings.

    Guaranteed Impact ››

    The university will see significant benefits from the improvements:

    ENERGY CONSUMPTION
    An estimated 6.2-million kilowatt-hour reduction in annual electricity use — enough energy to power more than 580 homes.
    GREENHOUSE GAS EMISSIONS
    Nearly 20,000 metric tons in fewer carbon emissions each year, which is equivalent to removing 3,600 cars from the road.
    ENERGY AND OPERATING COSTS
    Approximately $140 million in energy and operating cost savings over the next two decades.

    Prompt and decisive action to stop climate change is nothing less than the Great Work of our time.
