This project was a complete renovation for the Ballroom, which included the lighting and mechanical system. For the mechanical system, we replaced the original three air handling systems with three new efficient ones with variable frequency drives, as well as added chilled water to the system for better control of the temperature of the space. For the lighting portion of this project, all the inefficient lighting was replaced. These new fixtures reduced the wattage necessary and improved the illumination of the space. The estimated annual savings due to the lighting alone is $14,000 (FY12 rates).
