Appleby Case Study
Location: Appleby Ice Centre, Burlington Ontario
Background: Faced with rising electricity costs, the City of Burlington decided to invest in additional energy-saving initiatives at Appleby Ice Centre; Following a $16,500 in total utility reduction in 2013 stemming from a city-wide ice rink energy competition, the city continued to look for other ways to reduce consumption.
Solution: In 2014, Durell replaced the existing rink control system (For rink 1 & 2) with the DI2 solution, including floating head pressure optimization.
Results: Soon after final commissioning of the DI2 floating head pressure control system, the City of Burlington quickly noticed a reduction in energy use when compared to the same time period the previous year, as shown in the graph below. The additional savings realized is 43,576KWh, a cost of $7,290.00 for a period of 4 months.
