Building Energy Dashboard: 6 Metrics That Drive Action

In August, the boiler room of a Montreal building should be burning almost nothing. That is exactly what makes this month useful: with heating off, everything the gas meter still records is baseload — domestic hot water, pilots, a boiler held at temperature for no reason, a circulator nobody shut down in May. A building energy dashboard that cannot show you that summer baseload will show you nothing in January either, when the same anomaly disappears into the heating load. The best time to build the tool is while the building is idle.

What a building energy dashboard actually is

A building energy dashboard is a recurring view that compares a property’s actual consumption — gas, electricity, sometimes water — against expected consumption, and puts the gap in front of someone. It controls no equipment. It is a reading layer sitting on meter and utility data, and its value depends entirely on the response it triggers.

Three tools get confused with one another. A building automation system centralizes control and alarms: it acts, but it thinks in points and instantaneous states, rarely in energy. Energy benchmarking compares your property to similar ones once a year: that is a verdict, not a watch. The dashboard lives in between — continuous surveillance of your building against its own past, month over month.

The six metrics worth screen space

Energy monitoring dies of abundance. Six series cover what matters in a commercial building in Greater Montreal:

1. Gas normalized to heating degree days (m³ per degree day). The only metric that lets you compare two winters. A rising ratio at comparable degree days is an efficiency drift, never the weather.
2. Summer baseload. Gas consumption in a month with no space heating. This is your floor, and everything sitting on it is consumed twelve months a year — including the season nobody is watching.
3. Rolling twelve-month energy use intensity (GJ/m²). It smooths monthly noise and feeds the regulatory declaration directly.
4. Electrical peak demand. On a business rate, demand is billed separately from energy. A peak that climbs while consumption stays flat points to simultaneous starts, not to overconsumption.
5. Burner run hours and starts. Most modern control boxes already count them. A cycle count that doubles between seasons describes short-cycling, with the wear that comes with it.
6. Supply-return temperature difference on the main loop. A collapsing delta-T means excessive flow or unbalanced emitters — and, on a condensing plant, a return too warm to condense.

Main meter or submetering: how deep should you go?

The working rule: only submeter what you are prepared to correct. A meter installed on an end use nobody owns produces one more chart, not a saving. Where an open control network is already in place — a BACnet trunk, for instance — pulling existing points into the dashboard costs far less than adding hardware.

How long does it take to stand up?

The first level is a matter of days: the Énergir and Hydro-Québec business portals expose your account history, and a spreadsheet is enough to pair those values with degree days from the nearest weather station. The second level — interval data, automated collection, alerts — takes weeks and implies choosing a platform. The third — physical submetering — is a construction project, with shutdowns and commissioning attached. Plenty of buildings stop at the first level and capture most of the benefit, provided they have taken the next step.

Who looks at it, how often, and what triggers a call?

This is where a useful dashboard parts ways with a software subscription. A metric with no written response rule produces nothing. Three things get recorded once, for each metric you keep:

• a named owner — a person, not a department;
• a cadence — a monthly read at billing time covers five of the six metrics; peak demand deserves a weekly glance in season;
• a threshold and the action attached to it — for example: “if normalized gas runs 10% above the same period last year for two consecutive months, order a combustion analysis before month end.”

Skip the third item and the gap gets noticed, discussed, and carried forward. Keep it and the dashboard becomes an energy optimization trigger instead of one more report in a shared folder.

Montreal already requires the data your dashboard runs on

The raw material is now a legal obligation. Montreal by-law 21-042 covers buildings of 2,000 m² or more, or 25 dwellings or more: owners submit whole-building monthly energy consumption data by June 30 each year, for the January 1 to December 31 period preceding.

Province-wide, the calendar tightens. The Quebec government’s schedule sets a first declaration by June 30, 2027 for commercial and municipal buildings of 5,000 m² and up and residential buildings of 50 units and up — and it must carry monthly data for the two preceding years. Buildings of 2,000 m² or 25 units and up join in 2028. Which means the months you are living through right now are already reportable data. An owner who structures the tracking today satisfies a future obligation with a file they were keeping anyway; one who waits will be reconstructing twenty-four months of history under pressure in the spring of 2027.

What the Énergir and Hydro-Québec programs actually fund

Both utilities fund energy management systems, but read the eligibility before building a budget on it. Hydro-Québec’s program is aimed at Rate L industrial customers and special contracts: up to $600,000 in the implementation phase, including $350,000 for an energy management information system and $50,000 of measurement and verification over five years, plus a bonus of up to $1,000,000 for ISO 50001 certification. Énergir’s energy management system stream targets industrial customers burning more than 2 million m³ of natural gas a year: up to $175,000 at implementation, then 50¢ per m³ saved.

Most Montreal commercial buildings fall into neither box. What does transfer costs nothing: the structure these programs impose — a designated owner, a written measurement plan, a periodic follow-up report — is precisely what is missing from the dashboards that go dark after one quarter.

Field case: the summer baseload that was paying for a winter

Three-storey office building in Saint-Laurent, two hot water boilers and a domestic hot water loop. The manager, responsible for seven properties, tracked gas bills at the annual total. In August, consumption looked like May, June and July: steady, modest, never zero — and therefore never questioned.

The first dashboard, built from twelve months of bills, made it legible another way: summer baseload was running at close to a quarter of a January month. A boiler room check explained it — one of the two boilers stayed hot year-round to serve the domestic hot water loop, and a heating loop circulator had never been shut down in the spring. Two sequence corrections, no parts purchased. The baseload dropped by more than half the following month, and the fall bills confirmed it. None of this was hidden; it was simply added to something else.

Read your gas meter before the heating season restarts

One concrete step this week, with no software and no budget: write down today’s date and gas meter index, then do it again on September 1. Divide the difference by the number of days. That is your daily baseload with heating off — the first line of your dashboard, and the one measurement you can no longer take once the boilers come back on.

Then compare it to what you see in the fall. If the summer number looks high against the hot water your tenants actually use, that is a sequence verification mandate, not an equipment replacement — and it is the first gap the Montréal Combustion technicians look for when a manager hands us their last twelve months of consumption.
