Bowman provided engineering design services for the upgrade/replacement of the school’s entire HVAC system, which also includes the roof replacement for this 129,460 sq. ft. facility. Design incorporated new technologies, employing a year-round dehumidification, improved air filtration and distribution, improved efficiency, and implementation of modern controls and operations.
