    The city of St. Louis Public Library, in partnership with decarbonization company Veregy, has made several energy efficiency upgrades at its Buder, Schlafly, and Julia Davis branches as part of its sustainability efforts.

    The upgrades include installing solar photovoltaic panels, replacing outdated lighting with energy-efficient LED systems, and improving mechanical systems. The library has also implemented smart building automation systems using Veregy’s Orchestrate platform to manage energy use more efficiently and reduce costs.

    The 64kW (direct current) solar arrays at Buder and Julia Davis are expected to generate 161,940 kWh of electricity in the first year of production, resulting in over $18,700 in annual savings. Mechanical and lighting improvements will further reduce energy consumption by more than 390,000 kWh, saving an additional $39,000 each year.

    Additionally, the St. Louis Public Library has received $70,878 in utility incentives from Ameren Missouri and will be eligible to apply for Investment Tax Credits through the Federal Inflation Reduction Act (IRA) for the solar installations.

    These efforts are expected to reduce the library’s carbon emissions by 817,734 pounds of CO2 per year, equivalent to 931,964 miles driven by a typical car or the annual energy use of 45 homes.

    Veregy also installed solar monitoring stations that show real-time data on energy generation, offering library visitors a way to learn about renewable energy.

    “These upgrades not only enhance the comfort and experience for our patrons but also demonstrate our commitment to sustainability and responsible energy use” St. Louis Public Library’s Chief Operating Officer Justin Struttmann said. “We look forward to seeing the positive impact this project will have on our community and the environment.”
