Jacob Construction & Design, Inc. replaced an outdated solar thermal heating system for Building 383 Swimming Pool at Naval Air Station. Fallon, NV. Description This Design-Build project required Jacob Construction & Design, Inc. to replace the existing solar thermal heating system at Building 383 Indoor Swimming Pool. The existing system was designed to circulate the pool water through the solar panels in order to heat the pool. However, due to extreme temperatures that frequented NAS Fallon, the system could not be operated in the winter months. Additionally, there were issues with leaking pipes as a result of freezing and thawing year after year. The challenge for JCD and our partnering mechanical team was to replace the existing system with a climate-appropriate, fully automated, closed loop propylene glycol system. This new array of panels and piping was designed and configured to ensure durability against freezing temperatures, uplift from extreme winds and seismic activity. Additionally, as the mechanical room did not have the necessary ventilation and high concentrations of chlorine gas build up became an issue, JCD was asked to install exhaust fans, vents, louvers and automated controls to ensure continuous rotation of air. New solar thermal heating system has proven successful and effective in producing sufficient heat for the indoor pool for the past year.
