HVAC - A Busy Summer for Energy Management and District Teams

In addition to the normal summer maintenance and energy conservation projects, Energy Management district engineers, control engineers, technicians and District maintenance staff have been adjusting the campus HVAC systems to meet Center for Disease Control (CDC) and American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) recommendations for mitigating the spread of the virus that causes COVID-19. They have made significant improvements to the air flow systems in all buildings where feasible and are prioritizing the management of systems serving areas where there are group gatherings. The measures taken will increase air exchange and introduce fresh outdoor air at a higher rate. Actions include the following:
Verifying the proper calibration and operation of building HVAC systems.
Verifying and adjusting airflow rates in well over 1000 classroom, library, dining facilities and other group spaces.
Maximizing the introduction of outside air to these spaces/buildings in order to reduce recirculation as much as possible.
Disabling demand control ventilation (DCV) systems and occupancy schedules to operate HVAC systems continuously, completely flushing air from buildings each day after hours.
HVAC air handling systems are systematically having higher performance filters installed where possible, increasing filtration efficiency of recirculated air.
Portable filtration units to recirculate air through HEPA filters are being installed in non-mechanically (naturally) ventilated classrooms.
Thank you to all staff in Energy Management and the Districts for supporting our customers and the University’s Sunrise Plan by completing this very important work helping to stop the spread of COVID-19!
