Guaranteed Energy Only Utility Savings

Opportunity

For nine years, Brewer-Garrett has helped Kent State University reduce operating costs through a wide-ranging variety of energy conservation projects.

Solution

Brewer-Garrett completed a comprehensive array of energy conservation measures in two phases. Phase I was completed for campus classrooms, laboratory, and auxiliary buildings, the Summit Street power plant, and utilities infrastructure.

Improvements included:

  • Installation of new HVAC equipment in the athletic and convocation center, the student services center, and the ice arena
  • Retrofitting of lights across campus with LEDs and occupancy sensors
  • Installation of air handling units (AHUs)
  • Replacement of chillers, boilers, pumps, heat exchangers, and domestic water heating systems

We also provided complete upgrades to residence halls on the main campus.

Improvements included:

  • Repairs to building structures and windows
  • Synchronized belt drive retrofits
  • Roof replacement
  • Implementation of green initiatives
  • Inclusion of domestic water fixtures and laundry hook up
  • Improved steam distribution system (steam traps and insulation of steam valves)
  • Installation of demand control ventilation, restroom ventilation control, and occupancy-based ventilation
  • Implementation of display energy control systems
  • Upgrades to building automation
  • Controls for ice arena temperature
  • Installation of chilled water and boiler systems
  • Increased size of chiller lines
  • Installation of a reflective ceiling for the ice arena
  • Retro-commissioning

Special projects in the residence halls included:

  • Mechanical systems upgrades
  • Utility metering and auditing
  • Water-saving fixtures
  • Demand Control Ventilation (DCV) system
  • Occupancy sensors
  • Energy conservation education program

The Stark County Campus and other satellites received:

  • Lighting retrofits
  • Variable Air Volume (VAV) terminal controls
  • Mechanical systems upgrades
  • Occupancy sensors
  • Automated vending machine controls
  • High-velocity hand dryers
  • Conservation education
  • DCV automated systems

Phase II of this overhaul affected additional classrooms, laboratories, and auxiliary buildings.

We advanced the campus’s sustainability efforts through:

  • Building repairs
  • DCV systems
  • Domestic water fixture upgrades
  • Restroom ventilation control
  • Retro-commissioning
  • Stream trap repair and valve insulation
  • Mechanical upgrades
  • Enterprise optimization solution
  • Upgrade of Greenhouse HVAC and windows

Results

This project is targeted to achieve monetary utility savings for all four projects, over 15 years, of $170,056,058. Additionally, all the modifications will reduce capital costs, lower operating costs, and work toward meeting the 20% energy reduction goal.
