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.
