Loudoun County Public Schools

This project is a Guaranteed Energy Savings Contract for Loudoun County Public Schools (LCPS), a school district serving the area west of Washington D.C. The scope of the contract includes 100+ schools and administrative support facilities, approximately 13 million square feet. To date, LCPS has issued eight delivery orders under a master agreement for a total of $104 million, covering work on dozens of schools, including $13 million in solar photovoltaic arrays. Upon completion, the multi-phase contract is projected to include over $300 million in facility upgrades and save over $6 million annually.

The role of sustainability in shaping strategic decisions for Loudoun County Public Schools cannot be overstated. The district has joined nationwide efforts to reduce energy consumption and greenhouse gas emissions, driving significant environmental change. Since 2019, CMTA has been helping LCPS successfully implement their sustainability goals across their existing facilities, as well as several new buildings.

The significant results from CMTA’s Phase 1 project at J. Lupton Simpson Middle School established the guideline for energy conservation measures to be implemented across the school district. As part of Phase 2, 244,080 square feet within six facilities underwent HVAC renovations aimed at enhancing indoor air quality (IAQ). Two schools, Aldie Elementary School and Banneker Elementary School, received groundbreaking geothermal heat pumps, marking the first installation of such technology at LCPS. The success of these major renovations expanded the program to include these critical system replacements in conjunction with proven energy conservation measures.

The Phase 4 project provided a unique opportunity for CMTA’s Energy Solutions team to join forces with CMTA’s Design and Technology Solutions team to design a 562.5 KW solar photovoltaic array at Hovatter Elementary School, prior to the facility even being constructed. As soon as construction was complete on this new elementary school, CMTA’s Energy Solution team completed the installation of the solar array.

The highlight of the overall program is Ashburn Elementary School, which is included within Phase 8. The project is CMTA’s first Zero Energy Renovation to be designed and built by Performance Contracting. The design will become the standard for upcoming critical system replacements throughout the school district.
