How it works

See what your building is doing.

A sparse wireless array — about a dozen sensors for a whole building — plus your gas history feeds a model of how the building actually runs. Here's what happens, week by week.

First: is your building a fit?

Sound familiar?

01 Cold calls from the same suites Every January, the same corner units.
02 Windows open in winter Top floors dumping heat the boiler paid for.
03 A gas bill that doesn't track the weather Cold explains some of it — not all of it.

If the building runs on one central hydronic plant and went up before the mid-90s, it's in PENGA's wheelhouse.

The winter, step by step

What happens, and when.

  1. Day 1

    The install

    A sparse wireless array — sensors in a representative set of suites — plus two pipe clips and a gateway. A handful of five-minute visits with standard notice; most tenants never see us. Nothing touches your controls, and your operator walks the building with us.

  2. Weeks 1–8

    The model trains

    The simulator learns your envelope from gas history, weather, and the suite sensors — then replays your winter thousands of times. You do nothing. Your operator sees everything we see.

    The brief

    One document: where the heat goes with modeled dollar ranges, which suites carry comfort risk, and the recommended move. Every number traces back to your building's own record. See a sample brief

  4. The fork

    One of five answers

    Predictive control Mechanical fixes Rezone the loop Hybrid-ready plant Don't spend yet

    If the answer is controls, that's a separate, gated step: operator sign-off, qualified installation, and a hardware fail-safe that reverts to your existing controls.

  5. After the pilot

    Only what the building needs

    The brief and its recommendations are yours to keep, whatever you decide. If the building needs ongoing control, PENGA runs as a simple monthly service — no long contracts on a building that doesn't need us.

Straight answers

The questions owners actually ask.

Do tenants get disturbed?

Only a representative set of suites gets a sensor — one five-minute visit each, with standard entry notice. Most tenants never see us at all.

What data leaves the building?

Temperatures and plant telemetry. No tenant personal information, no cameras, no microphones — there's nothing to record.

What does my operator do?

Keeps the keys. They see the same data we do, and no control change ever happens without their sign-off.

What if the building's fine?

Then the brief says so. "Don't spend yet" is a real outcome — it protects your capital and our credibility.
