Project Description  

In 2018, Resource Consulting Engineers, LLC (RCE) teamed up with Summit Middle School to improve air quality and HVAC performance in the pool area. The existing system was outdated and no longer met the needs of the space. This caused comfort issues and increased maintenance.  RCE’s goal was to modernize the HVAC system while reusing as much of the existing infrastructure as possible.

Scope of Work  

The project involved full replacement of the pool’s HVAC equipment. RCE redesigned the ductwork to improve airflow and eliminate outdated return paths. A new floor-level exhaust intake was added along the east wall to capture air near the water. Supply registers were relocated, and unused openings sealed. Control systems were updated, and the electrical system was modified to support the new equipment. Though the original plan placed equipment in the mechanical mezzanine, the team mounted the new unit on the roof to ensure easy access and a cleaner installation.

Challenge Faced 

Pool remodels often come with unique challenges. This project was no exception. The team had to keep the pool operational during the school year. That meant dividing the work into phases. Long equipment lead times required careful coordination with contractors, users, and the commissioning agent. The project unfolded in two main phases: ductwork installation, followed by equipment replacement.

Project Outcome 

RCE delivered a targeted MEP design that replaced aging equipment and improved airflow control. The new layout improved air quality and made system maintenance easier. The design drew on insights from ASHRAE Research Project Report RP-1083 (October 2008). This study focused on chemical off-gassing, especially chloramines, in indoor pool spaces. These findings influenced how RCE positioned exhaust and return air systems to reduce harmful air buildup and improve comfort.
