The primary aspect of this job was active pressure control for several labs. With so much airflow being taken from the labs via fume hoods, point exhaust valves, and general exhaust valves, maintaining designed room offsets is key. We designed a system that utilized Accuspec Air Valves combined with the facility’s Honeywell BAS to ensure proper airflow to the spaces, while giving maximum flexibility and capability to the BAS. It addition to the Lab
airflow system, the BAS was rather extensive and included control of the chilled water system, hot water system, heat recovery loop, air handlers, and lab exhaust fans.
