The Numerical Building Corporation

Your building, by the numbers.

Minimum viable simulation from whatever information you happen to have lying around, so you can start asking questions, generating reports, and saving energy and money long before you ever integrate a single sensor or pull a single cable.

Coming Soon!

Most of the building data space works backwards — install the sensors, pile up the data, stand up a dashboard, then wait for someone to ask a question. The Numerical Engine starts from the other end. Here's how it works.

Feed the engine whatever you already have — a description, a spec sheet, a retrocommissioning report, a few utility bills. It turns that unstructured pile into a structured, minimum viable model of your building.

From that minimum viable simulation, the engine starts asking the questions that actually matter.

The Numerical Engine

It looks like you have single‑pane windows. Is that right?

0.5 U ≈ 1.0 1.5

Estimated window U‑value — right where single glazing lives.

YesNot sure

We're also seeing signs of low ΔT syndrome. How clean are your coils?

ΔT ≈ 8° 42° supply 50° return

Modeled chilled‑water supply vs. return — only ~8°F apart.

We need more data to be sure.

When a question is worth answering, you wire in live data — at your own pace. The simulation tunes itself to reality as it arrives.

… and the engine turns those questions into decisions — cost, incentive, payback, and what to do next.

Three ways in

Let the engine grow with you — don't buy what you don't need.

Numerical Rational

Start without pulling a single wire. We work with the utility data and documents you already have on hand to stand up our flagship decision engine and energy management system, powered by a minimum viable simulation of your site.

Numerical Complex

We live for the hard problems at the intersection of data, energy, and building physics. If you have a problem with an interesting shape that doesn't quite fit and requires some imagination, reach out.

Our principles are simple: work with what you have, and add data strategically.

Buildings are real, not virtual. Your problems are real, not virtual. Software should do its best to reflect the truth on the ground.

A product shouldn't take your time or your attention. You shouldn't even have to log in. Every interaction should be guided by a core question:

Yes No Is it right for us? Is your annual energy spend ≥ $200,000 a year? Definitely Possibly
