The Great Falls Library is now more energy-efficient and sustainable thanks to a recently completed energy project that supports Fairfax County’s climate goals.

The project replaced boilers and pumps and upgraded lighting, water fixtures, and building controls. The work also included improvements to the building envelope that enhance the library’s energy efficiency while making the space more comfortable for staff and visitors. By modernizing key systems, the upgrades are expected to lower energy consumption at the library by 15%.

“Our libraries are more than a place to check out books — they are truly a community hub and ensuring we operate sustainably is critical for both the environment and the residents we serve,” said Eric Carzon, director of Fairfax County Public Library.  “These updates create a more energy efficient, comfortable space while supporting Fairfax County’s broader commitment to sustainability and climate action. We’re proud to be part of this effort.”

Through its energy performance contracting program, the county is identifying high-impact, energy-saving projects at public facilities that can reduce utility costs and overall greenhouse gas emissions. So far this year, seven buildings received whole-building energy retrofits with four more slated to be completed in 2026.

These efforts to make county operations greener resulted in more than $6 million in savings from avoided utility costs in fiscal year 2024.

The Great Falls Library project showcases the vital role energy efficiency plays in protecting the environment while enhancing public spaces. “Projects like this are a testament to the county’s commitment to the goals outlined in our Operational Energy Strategy,” said John Morrill, Director of the Office of Environmental and Energy Coordination. “The upgrades at Great Falls Library demonstrate how targeted energy performance projects can reduce carbon emissions, lower utility bills, and create healthier spaces for the community.” 

Fairfax County Public Library Facilities Manager Kevin Brooks said that exceptional coordination with OEEC and the Facilities Management Department ensured the project was seamless for both staff and patrons. "The work done was substantial and there were nearly zero impacts to library operations," Brooks said.
