Published: Four ways to measure and bill thermal energy use
Updated on February 11th, 2021

In Canada, energy conscious communities are expanding their use of thermal energy systems for heating and cooling buildings. One challenge these systems face is the ability to effectively measure and bill thermal energy consumption to end users, such as condominiums, apartments, and commercial units.
Recently, REMI Network’s Condo Business published an article by Dustin Ingram, QMC’s expert on thermal energy metering. Below is an excerpt from the piece:
In Canada, the four main methodologies for measuring and/or allocating end consumer usage of thermal energy are:
- Thermal energy sub-metering
- Inferred measurement or run time measurement
- Ratio utility billing systems (RUBS)
- No metering or measurement
- Will the measurement methodology selected meet current and future regulations within Canada?
- Is the methodology used by more mature thermal energy markets, such as Europe?
- Can the methodology stand up to scrutiny if end-users dispute their bills? What international standards or hardware can they be directed to ease their concerns?
- Will the methodology be delivered by a provider who will correctly specify, deploy, manage and bill from the system in the long run?
