tpt-thermal

A Rust workspace for modeling, simulating, optimizing, and controlling thermal energy systems: district heating/cooling, thermal storage, heat pumps, boilers, CHP, solar thermal, telemetry, and control.

The project is local-first and simulation-first: it is safe to use as an analysis tool, and any real-hardware actuation is optional, explicit, rate-limited, and protected by safety constraints.

Crates

Crate	Purpose
tpt-thermal-core	Thermal quantities, units, time, identifiers, errors
tpt-thermal-assets	Sites, buses, zones, assets, and topology graph
tpt-thermal-models	Physical/behavioral models (boiler, heat pump, load, …)
tpt-thermal-storage	Thermal storage state and behavior
tpt-thermal-forecast	Forecasting abstractions and simple forecasters
tpt-thermal-solve	Dispatch and storage optimization (solver-agnostic)
tpt-thermal-control	Control policies and safety limiters
tpt-thermal-telemetry	Telemetry ingestion, normalization, and replay
tpt-thermal-sim	Simulation orchestration engine
tpt-thermal-cli	Command-line interface (tpt-thermal)
