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.
