As a result of the CUPR project, many buildings on campus have benefitted from additional energy conservation measures that maximize savings and energy efficiency. These measures decrease reliance on fossil fuels and improve occupancy comfort and performance by creating healthier spaces.
LED lighting was installed in 24 campus buildings as part of the project, improving lighting quality, providing exceptional user control, and using available daylight to reduce energy consumption. This has enhanced the learning and working environment for Fresno State students, faculty, and staff. It has also reduced the deferred maintenance load.
7,106 fixtures retrofitted
7,121 fixtures replaced
9,391 fixtures with new occupancy/daylight sensors
Wireless controls deliver enhanced energy management and flexibility and reduce energy
through:
Task tuning
Wireless occupancy controls
Wireless daylight harvesting
Zoning

The heating, ventilation, and air conditioning (HVAC) and energy management system (EMS) in 10 campus buildings was upgraded. The EMS monitors and controls the HVAC systems, along with all the other systems on campus, to maintain occupant comfort while increasing energy efficiency. The EMS provides real-time feedback which allows for adjustments to be made and issues to be addressed. All buildings on campus adhere to temperature setpoints of 68-78°F prescribed by California State Executive Orders.
What is zoned heating and cooling?
The HVAC system within the ten buildings functions in zones. Zoned heating is a method of controlling the temperature of different areas within a building using a single HVAC system. Within the ductwork, there are sensors and dampers that regulate and redirect air to specific areas within each building.
How does it affect me?
Like your house, the HVAC heating system heats and cools several rooms at once. When one sensor reads a temperature that is outside of the set points, all the rooms will be heated and or cooled. This creates office spaces or classrooms that are warmer or cooler than others while remaining within the bounds of the temperature setpoints of 68-78°F. Sensors are present in every room but cannot be individually controlled.

within the setpoints of 68-78°F.
HVAC and Control Upgrades
The HVAC and EMS upgrades that occurred include:
- 3200 Honeywell Control Points
- 42 Air Handling Units (AHUs)
- 53 Exhaust Fan Coils
- Over 330 Variable Air Volume Boxes
- 18 Variable Frequency Drives on AHU
- Outdoor Air Damper at Grosse Industrial Tech
The new EMS uses the University's existing fiber network to provide communication between building controls and the monitoring software. In addition to monitoring and controlling equipment in the central utility plant, the new EMS controls:
- Temperature setpoint optimization
- HVAC scheduling
- Discharge air temperature reset
- Outdoor air control
- Economizer control
- Demand-controlled ventilation
- Variable speed drives on air handlers and on pumps

Heat pumps were winstalled to support the domestic hot water (DHW) load for 14 campus buildings. These buildings require hot water year-round, and these new heat pumps meet this need in an energy efficient manner. During the school year, energy consumption is decreased because the pumps support the central boiler system.
