What we did
  • 369,000 ft2
  • MEP Commissioning
  • Testing, Adjusting, and Balancing

SystemWorks has been working with Johnston Community School District for several years, providing ongoing controls support and retro-commissioning.  In 2015, SystemWorks began working with Johnston on the design of their new High School, a 369,000 square-foot building featuring a displacement ventilation system with radiant in-floor heat.

Thirteen air handling units provide heating, cooling, and ventilation to the majority of the building.  The central plant consists of natural gas boilers and a multi-stack chiller, paired with a geothermal loop.  The building also has an area with variable refrigerant flow fan coils and an energy recovery ventilator.

Prior to bid SystemWorks reviewed the design to identify and document owner’s project requirements and anticipated standards for both mechanical and control systems to be implemented. The design review was documented and provided comments, concerns, issues and suggestions to the design team and owner.  SystemWorks provided twelve formal site observation reports during construction to document proper installation.  As the job progressed, SystemWorks worked with Woodman Controls technicians to perform detailed testing of the equipment according to the sequences and drawings. This step-by-step testing included simulating temperature changes, equipment failure conditions, and verifying scheduling. SystemWorks also reviewed the BAS graphics for accuracy, point mapping, trending, alarm reporting.
