Solar-powered hot water heater
Even under construction, the impressive solar panel array can be seen on the new Centennial Hall. This 24-panel array includes 960 square feet of solar collector space to supplement the energy necessary for this building’s hot water heating system. This solar hot water heating system has the potential to reduce greenhouse gas emissions by approximately 30,000 pounds of carbon dioxide annually from traditional use of natural gas or coal for heating water.
