This project at Mission Hall, completed in May of 2022, intended to improve the efficiency of the HVAC system in the building. The project focused on the AHUs (air handling units) and adjusting the pressure and temperature controls to maximize efficiency.
Background
Mission Hall is an office building located at 550 16th street in the Mission Bay campus of UCSF. It is 267,385 ft^2 and was built in 2014. Currently, UCOP provides the electricity and PG&E provides the natural gas. UCSF conducted a metering report and implemented a single ECM called the Energy Conserving Measure 1: AHU Supply and Exhaust Static Pressure Reset. This involved improving the scheduling to be more sensitive to occupancy during the day. Specifically, the team improved the light timers based on building traffic data to make sure that the lights were only on during active working times of the day. The team also installed sensors that allow for lights to turn off when no one is in the building.
Results
Upon completion of the project, the projected savings are 125,208 kWh, 13,314 therms, or 70.43 metric tons of CO2. This adds up to approximately $13,000 of annual savings plus an additional rebate of $19,482 from PG&E.
