Pearson Engineering was hired for a three-year project to install central air conditioning in school buildings. This was a two-phase construction project. Phase One included Olive-Mary Stitt Elementary School, Greenbrier Elementary School, Thomas Middle School, and South Middle School. Phase Two included Dryden Elementary School, Ivy Hill Elementary School, Patton Elementary School, Westgate Elementary School, and Windsor Elementary School.

Heating-only pipe systems were reused and converted to dual-temperature pipe systems. The reuse of existing piping, in lieu of creating 4-pipe systems, saved the school district over $3 million. DX coils in air handling units serving common areas, classrooms, and libraries were replaced with chilled water coils. New unit ventilators and fan coils were selected for dual-temperature delivery and economizer cycles. New chillers were provided to distribute chilled water throughout the schools.

Along with piping and equipment upgrades, new controls systems were incorporated into the schools. The new controls systems utilized occupancy sensors in all classrooms and offices and were designed for maximum energy efficiency. These systems centralized access to the units and their information, as well as standardized the control of similar units throughout the district.
