Incorporating submetering into a new building during the design and construction phase is significantly more efficient than retrofitting an existing building. Planning ahead avoids the limitations and costs that come with working around existing infrastructure.
The ideal time to engage a submetering provider is during the electrical design phase, before construction begins. At this stage, meter locations, communication pathways, and data infrastructure can be designed into the building rather than added later.
Key design considerations include meter placement in electrical distribution panels, communication wiring (typically a dedicated low-voltage pathway from meters to a central data collection point), network infrastructure for data transmission, and space allocation for metering equipment in each suite's panel.
Coordination with the electrical contractor is essential. The submetering provider should review electrical drawings, specify meter requirements, and coordinate installation timing with the construction schedule. Meters are typically installed after the electrical rough-in and before final commissioning.
For developers, the zero capital cost model used by most Ontario submetering providers means metering does not add to your construction budget. The provider funds the equipment and installation as part of their service agreement. This is a significant advantage over building your own metering infrastructure.
Before occupancy, the submetering system should be fully commissioned and tested. This means verifying that every meter is reading correctly, communications are functioning, and the billing system is ready to produce accurate bills from day one.
Starting with submetering from occupancy means residents never experience the transition from bulk metering. This avoids the communication challenges and potential concerns that come with converting an existing building.
