Reynolds was selected by the Phoenixville Area School District to develop an energy project master plan, a district-wide energy policy, and to provide a guaranteed energy savings project.
The guaranteed energy savings project addressed several district facilities, including Phoenixville Area High School, Barkley Elementary School, Schuylkill Elementary School, District Maintenance Offices, and the District Administration Office.
One of the unique features of the project was the high-efficiency chiller installed at the high school. The magnetic bearing chiller selected by Reynolds provides the district with significant operational efficiency gains over a traditional chiller, especially during part-load conditions. Additionally, it has substantially less required maintenance, which allows the district to achieve more operational savings over a more traditional technology.
As part of the guaranteed energy savings project, the district was interested in installing a solar photovoltaic system. Reynolds worked with the district to design the system to meet their specifications and also secured a $554,500 Pennsylvania Energy Development Authority grant from the PA Department of Environmental Protection to help fund the 250-kW solar photovoltaic system and other energy efficiency measures included in the project.
Another distinctive component of the project was the high-impact retro-commissioning process. At Schuylkill Elementary School there were numerous controls issues that had not been previously identified: CO2 sensors in the gymnasium and cafeteria that were not properly calibrated and were causing excessive outdoor air to be introduced into the spaces; inability to schedule the building properly; and administrative spaces being overcooled due to controls issues. Reynolds developed a plan to correct these issues as well as a preventative maintenance plan to ensure that all systems continued to operate at peak efficiency.
