JOHNSON CITY, Tenn. -- A utility analysis and subsequent decisions to improve building systems have resulted in a cost savings for Millennium Centre.
For the 12-month period of February 2009 to January 2010, building retrofits have led to $35,160 in savings over the previous 12-month period. The greatest savings were seen in electricity and natural gas costs, thanks in large part to a revamped control system.
“The control system allows us to use outside air in heating or cooling the building,” said Todd Smith, the City’s business management analyst. “For instance, if the air outside is 40 degrees, we will use that cool air to lower the temperature in the building whereas before, we would have to use chilled water.”
Smith also noted that the system allows a room’s temperature to be individually controlled.
“If a room is not scheduled to be used for a couple of days, we will lower its temperature in the winter or raise it in the summer. The control system allows us to use less energy if that particular room or wing of the building is not occupied,” he said.
Energy Systems Group, which led the utility analysis and building retrofits, has identified a 23 percent decrease in Millennium Centre’s carbon footprint since July 2009.
Millennium Centre staff have been working since 2008 to make the facility a leader in environmentally responsible practices. The Centre also earned JanPak Clean Zone certification last year for implementing “green” cleaning solutions and installing of touch-free restroom fixtures.
