Every building. Living Data.

Scan the building. Model it. Prove the return.

ThresholdStack collapses inspection, modeling, and energy operations into one platform. A robot scans your building in hours. BuiltLedger turns the scan into a living model. The model tells you which upgrades pay, then proves it.

One platform, every asset class. Every module ships for all five.

How it works

From a walk-through to a working model.

01

Read the building.

Our sensor payload mounts on any robot, quadruped, AMR, or drone, and captures the building in a single pass: LiDAR geometry, thermal envelope, equipment nameplates, air quality, moisture. The robot maps and navigates on its onboard NVIDIA Jetson, then hands the capture to our own GPU hardware for reconstruction.

02

Build the twin.

Capture data becomes a verified digital twin: a living model that updates with every scan and every sensor reading.

03

Find what matters.

BuiltLedger runs the physics. Which three upgrades move your ENERGY STAR score. What the retrofit returns, against real utility data and real incentive dollars.

04

Operate and earn.

Compliance filings come straight out of the data. On the Performance tier, the same model runs the building: equipment health, demand response, battery dispatch, and grid program revenue.

The stack

One platform. Three ways in.

SCAN · ROBOTIC CAPTURE

Autonomous building capture

A five-sensor payload on hardware you already trust. The first pass sets the twin baseline, and recurring scans keep it current.

MODEL · BUILTLEDGER

The single source of truth

Energy performance analytics, equipment lifecycle, incentive matching, and portfolio dashboards for every building you own.

OPERATE · GRID & CONTROLS

Flexibility into revenue

BoltOS, our OEM-agnostic energy controller, turns building flexibility into grid revenue on the Performance tier: demand response, storage dispatch, and DER enrollment.

Why owners switch

One record per building, kept current.

Floor area, equipment, utility data, and the 3D capture live in one BuiltLedger record per building. Capital planners price retrofits from it, asset managers answer lender and investor questions from it, and filings come out of it.

Floor area you can defend

Gross floor area measured from drawings, LiDAR, and parcel data, reconciled against ENERGY STAR Portfolio Manager and documented line by line.

How we measure it

Equipment you can plan on

Every chiller, RTU, and boiler logged with age and remaining useful life, so replacements get budgeted before they fail.

Incentives before capital

Planned projects matched against local, state, and federal programs before you commit the money.

Benchmarking, BEPS reporting, and third-party verification get handled along the way. Platform pricing starts at $2,500 per building a year.

Architecture

The platform is the product. The data is the moat.

Inputs

Robotic capture · building sensors (BACnet, Modbus, MQTT) · utility data · weather and grid signals · regulatory context.

Core

BuiltLedger performance modeling. EnergyPlus physics with AI surrogates, calibrated per building. Verified digital twins. Mapping runs on the robot. Reconstruction and modeling run on our own NVIDIA GPU hardware, and the platform runs in AWS US regions.

What compounds

Every scan, every meter reading, and every completed retrofit trains the models that price the next one. Buildings on the platform get smarter together.

Multifamily, regulatory bodies and corporate HQ · 242 buildings · 11 markets

Top-5 REIT source of truth

Capturing full portfolio building data, verifying it, and finding incentive opportunities while ensuring compliance.

Maryland Energy Administration

Working with MEA grant recipients and building owners, from property intake to the incentives that increase energy efficiency and lower costs.

Regulatory work

Direct engagement with regulatory bodies to keep reporting accurate, answers fast, and data validated, from gross floor area to incentive eligibility.

SiriusXM DC headquarters

Energy compliance and upgrades for world-class companies, improving ENERGY STAR scores along the way.

Coverage

A living platform, deployed coast to coast.

From a Maryland base to portfolios across the country, every deployment feeds the same models. More buildings on the platform means better physics for all of them.

FAQ

The questions owners ask first.

What is ThresholdStack?
A building intelligence company. We make SparkOS, the robot payload that scans buildings, BuiltLedger, the software that models them, and BoltOS, the controller that runs them. NVIDIA technology end to end.
Do I need to buy a robot?
No. Robotic capture is included on Planning and Performance, with our robot and our pilot. Most clients start with software only.
Does my building data leave the site?
The robot maps and navigates on its onboard NVIDIA Jetson. Capture files then move to ThresholdStack's own GPU hardware at our office (ours, not yours) for reconstruction, and the BuiltLedger platform runs in AWS US regions. Documents are parsed on our own hardware, and a person reviews every AI-extracted field before it enters your building record.
Which buildings does this work for?
Commercial, multifamily, industrial and manufacturing, data centers, and institutional buildings. Every module supports all five.
Do you handle our compliance filings?
Yes. ENERGY STAR benchmarking, BEPS reporting, and third-party verification are built into the platform, so filings come out of data you already have.
What does it cost?
Three tiers, published on the pricing page: Essentials at $2,500 per building per year, Planning at $8K per org plus $2K per building, Performance at $30K per org plus $2K per building.
