Located in Lower Pottsgrove Township, PA, Pottsgrove School District (PGSD) serves over 3,000 students across five schools. In 2022, PGSD partnered with CMTA, a Legence company, along with its sister companies, Provident Energy Consulting and ICS, to perform a guaranteed energy savings contract project aimed at renovating its facilities, reducing operational costs, and improving energy efficiency. The project team collaborated to identify energy-saving opportunities and manage construction for this multi-phased project.
Phase 1 of the project, which effectively reduced the facility's annual energy consumption by 9%, included the following upgrades:
- New LED fixtures and retrofit solutions were installed throughout the 58,306 SF Ringing Rocks Elementary School
- The existing Encelium controls system and associated components were replaced with new switches, dimmer switches, occupancy sensors, power packs, and input/output modules
- All windows in the music room of Pottsgrove Middle School were replaced with new double-pane windows to address water infiltration issues
Phase 2 included a complete HVAC renovation at the 60,000 SF West Pottsgrove Elementary School, resulting in an impressive 40% reduction in annual energy consumption. The scope of work included:
- A complete geothermal HVAC renovation, involving the demolition of the existing 4-pipe HVAC system and installation of a new water source heat pump system with a geothermal wellfield
- A complete roof replacement
- Retro-commissioning opportunities at several other schools across the district to identify failed sensors/other control devices and implement optimized control sequences to correct excessive energy consumption and comfort issues, resulting in a 17% reduction in annual energy consumption
The geothermal renovation is eligible for a direct rebate payment under the Inflation Reduction Act (IRA).
