A utility bill tells you what a building spent. A review cycle is what turns twelve of those bills into a decision worth acting on — here is how to run one on a schedule instead of by accident.
Key takeaways
STEP 01 OF 11
Utility data should be loaded into your tracking system every month, as bills arrive — not batched once a year before budget season. A monthly ingestion habit is what makes the annual deep review possible at all; without it, the annual review becomes a data-entry project instead of an analysis.
Keep the monthly step mechanical and the annual step judgmental. Someone enters twelve numbers a year without deciding anything; once a year, someone else looks at all twelve together and decides what, if anything, changed.
A missed month is worse than a late one. If a bill hasn't arrived by the usual date, flag the gap immediately rather than letting the annual review discover a blank cell in month nine.

ENERGY STAR Portfolio Manager is described by Natural Resources Canada as a "free, online, secure platform" for benchmarking building energy performance against similar structures, with certification eligibility starting at a score of 75 (natural-resources.canada.ca). The page frames it explicitly as "an ongoing review" rather than a one-time exercise.
A score built on eight months of data and four months of estimates is not a score you can act on. Wait for the full twelve months before drawing a conclusion about a building — a partial year understates or overstates performance depending on which months are missing.
Portfolio Manager also supports "uploading energy data automatically to utilities" and tracking water usage and waste alongside energy, so the same platform can carry more of the annual review than the energy line alone once the monthly habit is established.

A 40-year-old low-rise and a five-year-old mid-rise will never spend the same dollar amount on utilities, and comparing them by raw spend tells you nothing about which one is actually performing worse. Portfolio Manager's normalized score exists precisely to make that comparison fair — use the score for ranking, and raw dollars only for the budget conversation that follows.
A building sitting in the bottom quartile of your own portfolio, even with a respectable-looking score, is the one that earns a walk-through this cycle. Relative performance inside your own portfolio is often a more useful signal than the absolute score.
STEP 05 OF 11
Unit sub-metering in Ontario is a licensed activity: "Section 57(c.1) of the Ontario Energy Board Act, 1998 states that no person is permitted to engage in unit sub-metering without a licence" (oeb.ca). A new applicant pays a $1,000 non-refundable fee; a licensed provider pays $800 annually; and every licensee "must comply with the OEB's Unit Sub-Metering Code and all other conditions set out in their licence."
A submetered building's utility variance reflects individual-suite behaviour that a bulk-metered building's does not. Comparing the two directly, without noting which is which, will misattribute a behavioural difference to an equipment or operations difference.

Statistics Canada's Daily release on investment in building construction gives a dated, sourced national and provincial context figure — useful once a year to sanity-check whether your own capital timing is moving with or against the broader market, never as a substitute for your own building-level data. The May 2026 release, for example, recorded total investment in building construction at $23.4 billion, up 5.9% year over year, with the residential sector at $16.2 billion (StatCan Daily, released 2026-07-20, Table 34-10-0293-01).
Cite that figure with its release date and table number every time, and never carry a month's number forward into a later month's review — the Daily republishes on its own schedule and an old figure ages out quietly.

IESO runs a Capacity Auction where "businesses are eligible to compete in the auction, turning their demand response capabilities into revenue," and a separate Industrial Conservation Initiative "for medium and large-sized businesses and facilities" that rewards shifting energy use away from high-demand periods, with combined reductions cited "as much as 1,500 MW" (ieso.ca).
Eligibility and qualification mechanics live on IESO's own programme pages, not on this overview page — treat this step as a prompt to check eligibility annually, not as the source of the qualification rules themselves.
STEP 08 OF 11
A building that fell from one percentile band to a lower one deserves someone walking the mechanical rooms before a capital request gets written. A dropped score can mean a failed piece of equipment, a change in occupancy, an unusually cold winter, or a billing error — and only one of those is a capital problem.
Log the walk-through finding against the building record either way. Even "nothing wrong, just a cold February" is useful information the next time that building's score moves.
STEP 09 OF 11
Clean-energy and energy-conservation equipment can qualify for accelerated capital cost allowance under ITR Schedule II Class 43.1 or 43.2, subject to the same half-year-rule carve-out that applies to other CCA classes (ITR, current to 2026-06-17). That changes the after-tax payback math on a capital request enough that it belongs in the business case, not as a footnote after approval.
This is a tax-treatment question, not an energy-savings claim — no Canadian source publishes a net-zero-ready cost premium or a standard payback percentage, so keep the business case to the mechanism (CCA class, half-year rule) and your own building's numbers, not an imported industry figure.
STEP 10 OF 11
Occupancy, weather and equipment changes all move a utility number independent of anything a building operator did. Note them against the building record before the annual review meeting, so the conversation is about what changed and why, not a bare number that invites a defensive explanation on the spot.
A one-line note at the time an occupancy or equipment change happens is worth far more than trying to reconstruct the reason for a dip eleven months later.
STEP 11 OF 11
Every building gets one page: its score, its percentile rank, what changed, and what (if anything) was decided. The decision log matters as much as the score — "reviewed, no action" is a legitimate outcome, and recording it prevents the same building from being re-litigated at the next cycle with no memory of the last one.
File the summary alongside the compliance calendar entries from the portfolio-wide register, so a board or an owner reviewing one building sees the full picture in one place, not scattered across two systems.
Comparing a submetered building to a bulk-metered one by raw dollar variance. The two measure fundamentally different things — one reflects aggregate building consumption, the other reflects individual suite behaviour layered on top of it. Separate the comparison sets before drawing any conclusion.
Treating a single bad month as a trend. A cold snap, a one-time equipment failure, or a billing correction can all move one month's number sharply without meaning anything about the building's underlying performance. Wait for the pattern across the full cycle.
Running unlicensed sub-metering activity because a building 'already had the meters installed.' The licence requirement under OEB Act s.57(c.1) attaches to the activity, not to whether the equipment was inherited from a previous manager. Confirm licensing status before continuing to bill suites individually.
Scenario. A portfolio manager is deciding whether to bring unit sub-metering in-house across three buildings rather than continue contracting it to a licensed third party. A new OEB unit sub-metering licence costs $1,000 to apply for, plus $800 a year to hold once granted — a first-year cost of $1,800, and $800 a year after that, before any metering hardware, billing software or staff time is counted. That figure alone is the threshold question: does bringing the activity in-house across three buildings clear $1,800 in year one against whatever the third-party provider currently charges for the same three buildings? Get that answer from your own contracts, not an assumed savings percentage — no Canadian source publishes one.
The $1,000 / $800 licence fee structure and the s.57(c.1) requirement come from the Ontario Energy Board Act, 1998 — an Ontario-only regime. British Columbia and Alberta regulate utilities and metering through their own boards (the BC Utilities Commission and the Alberta Utilities Commission respectively), under separate legislation with separate fee schedules. Do not assume the Ontario numbers, or the licensing requirement itself, transfer to a building outside Ontario — confirm the applicable provincial regime for each jurisdiction a portfolio operates in.
Enter data monthly as bills arrive, but judge the score against the full trailing twelve months, updated at the annual review. Checking a partial-year score mid-cycle is useful for catching a billing error, not for judging performance.
Only buildings where suites are billed individually for utility consumption. A bulk-metered building where the corporation or landlord pays one utility bill for the whole property has no licensing exposure under this rule at all.
Run the walk-through step early rather than forcing a score out of partial data. A building new to the portfolio, or one that changed metering arrangements mid-year, is better flagged as 'insufficient data, revisit next cycle' than scored on an estimate.
Before. A capital ask that has already been through the CCA-class lens and the walk-through step arrives at budget season as a costed decision, not a question the board has to research on the spot.
Yes, on the same annual track as the rest of the cycle. Eligibility criteria and programme thresholds are IESO's to set and can change; a building that didn't qualify two years ago isn't necessarily still excluded today.
A 30-minute call is enough to map which buildings in your portfolio need one first.
