All lights in the parking area and stairwells were replaced with vandal resistant energy-efficient LED lights. This improves light quality, reduces maintenance costs and saves energy.
142,000 kWh/yr 2,840 kgC02e/yr $150,000
Waterworks electrical room cooling right-sizing
Cooling is needed for electrical equipment to function safely. The old oversized cooling system was replaced with right-sized modular equipment that can provide the appropriate level of cooling as weather effects and equipment usage change.
28,000 kWh/yr 560 kgC02e/yr $21,000
Victoria Road Recreation Centre ice plant controller
plant control system was installed to optimize cooling tower and compressor
201,000 kWh/yr 4,020 kgC02e/yr $29,000
Norm Jary splash pad variable speed drive pump
Pump was right-sized and variable speed drive was installed to allow for better pump control. This reduces water and energy use.
4,000 kWh/yr 3,680 m3/yr 80 kgC02e/yr $39,000
City Hall parking, exterior and stairwell LED lighting retrofit
LED lighting retrofit with controls to improve lighting conditions and automatic turn off and dimming based on occupancy.
62,000 kWh/yr 1,240 kgC02e/yr $42,000
Farmer’s Market LED lighting retrofit and destratification fans
Five destratification fans installed to improve air movement and thermal comfort. All lights have been upgraded to LED.
13,000 kWh/yr 1,300 m3/yr 2,714 kgC02e/yr $28,000
Fire Hall #4 water heater upgrade
The old inefficient draft appliance water heater was replaced with a high-efficient condensing unit that recovers exhaust heat to preheat water.
10,000 m3/yr 18,880 kgC02e/yr $5,000
Burke well variable speed drive pumps
The well pump and booster pump were upgraded with variable speed drives for enhanced controls and more efficient pumping.
111,000 kWh/yr 2,220 kgC02e/yr $30,000
What we’re planning
LED streetlights and controls
Nearly 13,000 non-decorative streetlights are to be upgraded to LED with network controls. This will improve light quality and reduce operating and maintenance costs.
9,465,000 kWh/yr 189,300 kgC02e/yr $8,000,000
Victoria Road Recreation Centre cold water ice flooding
Traditionally water is heated to remove air bubbles before flooding and resurfacing ice. An engineered device is to be installed to remove air bubbles using fluid dynamics. This will improve ice quality and reduce the need to heat water for flooding.
West End Community Centre cooling tower replacement with variable speed drive
The existing cooling tower is at the end of its useful life and is to be replaced with an energy efficient unit equipped with a variable speed drive.
19,500 kWh/yr 390 kgC02e/yr $30,000
West End Community Centre pool drain heat recovery
A control system will be installed to optimize pool water drainage rates and recover waste heat from drained pool water to preheat fresh pool water.
9,000 m3/yr 1,460 m3/yr 16,992 kgC02e/yr $30,000
Zero emissions electric ice resurfacers
Two propane fueled ice resurfacers are being replaced with battery electric models. This will improve indoor air quality by eliminating indoor exhaust and reduce fuel costs and building ventilation requirements.
Detailed design is to be done for the aeration blower upgrades. The upgrades will improve control of air supplied to the treatment process and significantly reduce energy demand by 6,750,000 kWh/yr at the Wastewater Treatment Plant.
