PENGAby GlacialRift

Older hydronic apartment buildings · Edmonton & Calgary

Stop heating the outdoors.

Overheated suites open windows in January while cold suites call the office. PENGA watches the building live — sampling suites and modeling the rest — so it stops paying for both.

Check my building See what you get

So far this is simulation, not field proof: PENGA's models show roughly 6–35% gas headroom versus a neutral outdoor reset, with no controller running in a real building yet. Field results start with two founding buildings — one could be yours.

One boiler serves every suite — heat rises, corners freeze

The engine

Your boiler is flying blind. The simulator isn't.

Weather drives the plant, the plant drives the concrete, the concrete drives every suite. PENGA nests those models into one simulator, replays your winter thousands of times, and puts the results to work.

Predictive controlA controller trained on your winters, steering ahead of the weather.
Predictive maintenancePlant drift flagged before it becomes a mid-January failure.
Retrofit callsZoning, hybrid plants, and fixes sized against the model — not a rule of thumb.

One building, replayed in simulation

One cold snap. Two controllers.

Same building, same weather. Watch what a reactive controller does to the suites — and what PENGA does instead.

The deliverable

One install. Your building's answer.

Every building gets the same core — suite sensors, pipe clips, and a thermal model trained on its own winter. The recommendation is whatever the building actually needs. Sometimes it's "don't spend yet."

Next move: the plant is sound but always reacting. The envelope holds 7+ hours of heat — a strong candidate for predictive control, within limits your operator sets.

Sometimes the honest answer is: "don't spend yet."

The brief tells you when a fix pays — and when your building doesn't need us at all.

The common core

Every answer starts with the same one-day install.

Suite sensors, pipe clips, one gateway — no BAS, no rewiring. Sensors only read; your operator keeps the keys.

12× suite temperature 2× pipe contact 1× wireless gateway

Where this goes

From reading the building to running it.

The same install that finds the waste trains a controller on your building's own winter — in simulation, 6–35% less gas than a neutral outdoor reset, though no controller has run in a real building yet. And as Alberta's electricity market restructures, buildings that can shift their load may be able to earn from it. This install is how a building gets ready.

Step 01 Model

A working model of your building, learned from your gas, weather, and suite data.

Every winter on record makes it sharper.
Step 02 Recommend

Controls, mechanical fixes, rezoning, or a hybrid plant — sized against the model, not a rule of thumb.

Sometimes the answer is "don't spend yet."
Step 03 Control

PENGA steers the plant ahead of the weather, within limits your operator sets.

Operator sign-off · qualified installation · a hardware fail-safe that reverts to your existing controls.

Simulation results are internal benchmarks versus neutral outdoor reset — individual weather replays ranged from 6% to 35%. Not field-verified savings; no active control runs in any building today. Grid-payment programs depend on Alberta market rules as they land.

Two founding spots province-wide — GlacialRift contributes the engineering to the selected buildings. No control changes. Third-party costs need separate written approval.

You bring

  • Your winter gas history
  • Boiler-room access
  • The person who knows the plant
  • OK to share anonymized findings

Principal-led: you work directly with the engineer who built PENGA, in Edmonton.

No field results yet — that's exactly what these two buildings are for. Afterward, if a building needs ongoing control, PENGA runs as a simple monthly service. The brief is yours either way.
