A new air-cooled chiller was provided to serve zoned chilled water fan coil units (FCUs) throughout each building. New gas-fired boilers provide space heating and humidity control via hot water coils at each FCU. Each hydronic system includes redundant pumps in a primary-only configuration to limit equipment footprint and provide system redundancy. New piping, pipe specialties, ductwork, and grilles, registers, and diffusers were provided throughout the school’s three buildings.

New direct digital controls and building automation system were provided to remotely monitor and control all HVAC systems. Controls were integrated with the school district’s central building management system.
Electrical systems were provided in support of the HVAC system replacement, which included a new service panelboard, power systems to serve new HVAC equipment, new lighting fixtures in Building 1, lighting fixture relocation in Building 2 and 3,and fire alarm system integration with new HVAC equipment.

To support the mechanical upgrades the aging service entrance switchboard and mechanical panelboards were replaced. Surge protection was specified for each new panel and switchboard to improve power system protection and system reliability.

The project included a wet pipe fire sprinkler system for one of the site’s three educational buildings based on code requirements and to limit HVAC system life safety requirements (i.e. fire dampers).

All work was coordinated with the school’s operating schedule to eliminate outages during occupancy. Routing of utilities were coordinated with the existing 1950’s structure that was originally designed with no central HVAC systems.
