The City of Dayton's energy conservation and sustainability achievements are recognized by the United States Environmental Protection Agency with an Energy Star designation for the century-old City Hall building located at 101 W. 3rd St. The Energy Star certification follows the installation of more than 1,500 energy-saving T8 lights, a heating/air conditioning system upgrade, weatherization and other improvements. The City Hall upgrade is part of a 10-year energy savings performance contract with Honeywell designed to reduce costs and modernize facilities while saving energy. The contract involves 12 City of Dayton facilities, including City Hall, and allows an estimated $420,000 annual savings in energy and operational costs.
