EPC PROJECT UPDATES
After a careful evaluation of the technical and economic feasibility of different energy efficient measures, several initiatives were selected to be implemented across more than 100 buildings at the base! These measures include:
Lighting – LED Retrofit and Controls
- By upgrading existing light technologies with alternatives such as LED lighting fixtures this measure will increase lighting efficiency by up to 70%. We are also adding occupancy sensors to control lighting according to real-time occupancy and lighting conditions in over 80 buildings!
New Rooftop and R22 Units
- Certain buildings at CFB Kingston are equipped with aging rooftop units that use R22 refrigerant. This refrigerant was banned from production, distribution, and installation in 2020 because of their harmful effects to the ozone layer. The project will look to replace these units with new energy-efficient alternatives with increased insulation, modulation capabilities and longer lifecycles!
Peak Shaving
- Peak power demand periods are like rush hour traffic, applied to electricity. The difference is that CFB Kingston is charged based on how our buildings energy consumption contribute to the overall provincial peak demand through what is called the global adjustment.
- To limit these expensive charges, the project will look to implement new ground mounted solar photovoltaic systems (PV) as well as a Battery Energy Storage System (BESS) that will be used to produce and store electricity for the Base during peak electrical periods. This will be the largest energy conservation measure and will significantly reduce peak demand!
Piping Insulation and Steam Trap Survey
- A central heating plant is heating and cooling several buildings at CFB Kingston. Steam (in winter) and chilled water (in summer) are distributed to these buildings through a piping network.
- Adding insulation to the piping helps to maintain the steam and chilled water at an optimal temperature until it reaches the buildings and avoids efficiency loss on the network. We are also inspecting steam traps in the steam piping network and replacing the aging traps to avoid leaks, another cause of energy loss!
Window Replacement
- The intent of this measure is to replace windows in buildings with excessive air infiltration so that the sealing around the windows will also be substantially improved!
Water Conservation
- The intent of this measure is to replace water fixtures including toilets, urinals, faucets and shower heads with higher efficiency alternatives to reduce water consumption. Additionally, by conducting leak detection surveys across the base.
The work will be paid through the savings generated by the new energy efficient systems. The project is expected to result in annual savings of over $5.6 million while also reducing GHG emissions by 5,864 tons of CO2 equivalent. That is the same as removing 1,800 passenger vehicles off the road or powering 1,375 homes for one year!
