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.
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.
Capture data becomes a verified digital twin: a living model that updates with every scan and every sensor reading.
BuiltLedger runs the physics. Which three upgrades move your ENERGY STAR score. What the retrofit returns, against real utility data and real incentive dollars.
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.
A five-sensor payload on hardware you already trust. The first pass sets the twin baseline, and recurring scans keep it current.
Explore Robotic CaptureEnergy performance analytics, equipment lifecycle, incentive matching, and portfolio dashboards for every building you own.

BoltOS, our OEM-agnostic energy controller, turns building flexibility into grid revenue on the Performance tier: demand response, storage dispatch, and DER enrollment.
Explore Grid & ControlsFloor 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.
Gross floor area measured from drawings, LiDAR, and parcel data, reconciled against ENERGY STAR Portfolio Manager and documented line by line.
How we measure itEvery chiller, RTU, and boiler logged with age and remaining useful life, so replacements get budgeted before they fail.
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.
Robotic capture · building sensors (BACnet, Modbus, MQTT) · utility data · weather and grid signals · regulatory context.
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.
Every scan, every meter reading, and every completed retrofit trains the models that price the next one. Buildings on the platform get smarter together.
Capturing full portfolio building data, verifying it, and finding incentive opportunities while ensuring compliance.
Working with MEA grant recipients and building owners, from property intake to the incentives that increase energy efficiency and lower costs.
Direct engagement with regulatory bodies to keep reporting accurate, answers fast, and data validated, from gross floor area to incentive eligibility.
Energy compliance and upgrades for world-class companies, improving ENERGY STAR scores along the way.
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.
