The Roovie Physics Engine
A fully coupled heat balance, solved from first principles — independently verified against ASHRAE 140 and designed end-to-end for automation. Not a wrapper. Not a shortcut. A new foundation.
▸ Fully coupled heat balance
At every timestep, the engine resolves the weather outside, the loads and schedules inside, the envelope between them, and the HVAC system that responds — as one simultaneous equation set. No sequential decoupling. No lagged zones. Every surface, every zone, every air node, every moment.
Real EPW files push dry-bulb, humidity, solar, and wind into every envelope surface — every hour, every zone.
Occupants, plug loads, lighting power, and setpoints each run on their own schedule — all contributing heat to the zone balance.
Airflow, coil capacity, and plant response couple back into zone temperature, humidity, and surface temps — all at the same timestep.
▸ Why we built our own
Wrapping someone else's solver — or simplifying the math — inherits an architecture that can't keep up with cloud orchestration, AI agents, or custom reporting. Owning the engine means every layer above it can be accelerated, extended, and automated.
▸ Built for the workflows that matter
Rigorous heat-balance physics is the foundation every serious compliance and reporting workflow requires. One simulation feeds your 90.1 Appendix G baselines, LEED EA credits, ENERGY STAR scores, code-compliance paths, utility rebate filings, and carbon disclosures — no model forks, no re-runs.
▸ From physics to outcomes
The solver resolves temperatures, flows, and fluxes. What teams actually need — energy, dollars, carbon, comfort — flows straight out of that physics. No bolted-on assumptions.
▸ Concurrent runs · autonomous agents
The engine runs elastically in the cloud. A modeler can launch ten parallel simulations and pick the winner — or hand the wheel to an AI agent that runs the sim, reads the result, tunes the model, and proposes the next move.
▸ Climate change weather module
Real EPW files for today. Generated future weather for any year, scenario, or warming pathway the modeler cares about. The same heat balance, re-solved against a shifted boundary — so resilience decisions are made on physics, not hunches.
▸ Run from anywhere
Because the engine runs in the cloud, a modeler doesn't need a workstation to simulate. Kick off a run from an iPad during a site walk. Watch it converge on a phone. Show the owner the savings before leaving the parking lot.
