Hennepin County Public Works Facility Photovoltaic Solar Array
Project Type: Photovoltaic Solar Array; Hennepin County, MN
Client: Hennepin County
Hennepin County is providing a leadership role in generating clean and affordable electricity from a variety of renewable energy sources, including solar energy. LHB is the designer and engineer of record for the newest photovoltaic array system, the second largest in the state, installed on the roof of the Medina Public Works Building. LHB initially provided a feasibility study to determine Hennepin County’s energy needs and to develop a method to install a solar electric energy system rated to 97 kW on the roof of the Public Works Facility. LHB worked with solar suppliers to determine which system concept would work best within the space restrictions of the roof. In addition to generating approximately 5% of the building’s energy, the array benefits the environment by saving approximately 100 tons of carbon dioxide emissions on an annual basis and more than 2,500 tons of greenhouse gas over the life of the array system.
