The Two Hills Centennial Arena is a year-round municipal recreation facility supporting ice operations, lighting, ventilation, and community use across changing schedules and seasonal demand. While monthly utility bills showed overall consumption, they offered little visibility into what was actually happening inside the facility.

Systems continued operating behind the scenes, smaller loads quietly accumulated over time, and hidden operational waste remained difficult to identify without deeper visibility.

The Problem

The Bills Kept Rising — But The Cause Wasn’t Clear

The arena depended on multiple systems operating continuously throughout the day, including

The arena depended on multiple systems operating continuously throughout the day, including heating, lighting, ventilation, plugs, and support infrastructure.

While everything appeared to be functioning normally, there was little visibility into how efficiently the facility was actually operating.

Utility bills showed total energy use , but they couldn’t explain which systems were driving demand, where energy was being wasted, or how much unnecessary runtime was occurring behind the scenes.

The Discovery

What They Found Was Happening Every Day

Once real-time circuit-level visibility was introduced, the facility uncovered 69 separate areas of energy loss across the arena.

Systems were operating beyond active ice hours, support equipment continued running overnight, and persistent plug loads quietly maintained continuous demand throughout the building.

The analysis identified an estimated 18.90% energy savings opportunity hidden inside everyday operational behavior.

The Impact

The Facility Never Truly Powered Down

The findings revealed that a significant portion of the arena’s energy use continued during periods of reduced activity. Lighting, heating, ventilation, plugs, and support systems maintained steady demand even when occupancy dropped.

Loads continued overnight, systems operated longer than necessary, and unnecessary consumption quietly accumulated month after month.

Individually, many of these loads appeared minor — but together they created a large layer of hidden operational waste that quietly increased monthly operating costs over time.

The Shift

Operational Visibility Changed The Conversation

Instead of relying on assumptions and monthly utility totals, the facility could finally see how systems were behaving throughout the day.

Runtime patterns became measurable, unnecessary demand became visible, and operational decisions became more targeted.

The arena shifted from reacting to energy bills toward understanding the operational behavior driving them.

Why it Matters

Utility Bills Don’t Show What Facilities Are Actually Doing


Most facilities already have energy data — but very little operational visibility.

Utility bills can show total consumption, but they cannot explain which systems are responsible, when equipment is operating unnecessarily, or how hidden runtime behavior impacts costs.

Opti-mized transforms electrical infrastructure into operational intelligence, helping facilities finally understand how they truly operate day-to-day.

Opti-mized detected 69 instances of energy loss across four main categories. Each represents hidden costs that add up quickly.

Energy loss breakdown chart

Energy Loss Detected


  • Off-Hours:
  • On-Hours Overusage:
  • Standby / Idle:
  • High Continuous Loads:

Off-Hours Waste

Energy used when facilities are closed or unoccupied — systems left running overnight, on weekends, or during downtime.

On-Hours Overusage

Extra energy consumed during regular operating hours — systems drawing more power than necessary for the activity taking place.

Standby / Idle Loads

Power used by systems that remain on or in standby mode even when they’re not actively being used.

High Continuous Loads

Systems that run at high levels for long stretches without adjustment, even when demand is lower.


The Biggest Energy Costs Rarely Look Big

Small Inefficiencies Became Expensive Fast


Most facilities don’t lose energy through one obvious issue.
They lose it through dozens of small operational behaviors happening every day:

  • Systems running longer than needed
  • Lights staying active after-hours
  • Support equipment operating continuously
  • Small loads quietly accumulating month after month. Utility bills show totals.

Operational visibility shows what’s actually causing them.

This Isn’t About More Data

Facilities Needed Answers, Not More Graphs


Most facilities already have data.
What they lack is visibility into how the facility is actually behaving.
Opti-mized helps uncover:

  • Where energy is being lost
  • Which systems never truly shut down
  • What runs longer than expected
  • and Which operational patterns quietly increase costs every month

The goal isn’t more graphs.
It’s understanding what deserves attention first.

Small Operational Waste Becomes Big Fast

How “Normal” Operations Increased Costs


One light left on overnight doesn’t seem important.
Neither does:

  • A fan running longer than necessary
  • A plug load that never shuts off
  • Or a support system operating continuously

But across dozens of circuits, every day, every month —
those small operational behaviors quietly compound into major operating costs.

The Facility Wasn’t Broken. It Was Bleeding.

Everything's Running - That's the Problem


The hardest energy waste to detect is the kind that looks normal.

  • Small runtime overruns.
  • Continuous plug loads.
  • Support systems operating without demand.

Individually, they barely stand out.
Together, they quietly drive thousands in avoidable operating costs over time.
