Barrett Elementary School was originally built in 1939 with additions and major renovations in 1973, 1994, and 2001. The HVAC systems were completely replaced during the 1994 addition/renovation and were modified again in 2001. As expected, the systems that weren’t upgraded in 2001 had either reached the end of their service lives or were in poor condition by 2013. Of particular concern were non-functioning air conditioning controls, excessively high indoor humidity levels, and inadequate ventilation in the gym, cafeteria, and administration areas.
2RW performed a facility condition assessment to provide a comprehensive overview of systems that had been implemented in multiple phases. These services included:
2RW was then selected to refine the schematic recommendations into full construction bid documents for HVAC system renovation. Upon completion, 2RW performed retro-commissioning which included test preparation, equipment testing, TAB work, controls review/report, and an investigation phase report.
A majority of the HVAC systems were replaced and connected to the existing APS central building automation system.
