Build an EnergyPlus Envelope Thermal Transmittance Upgrade Planner

Process commercial building envelope assemblies in EnergyPlus epJSON format. Synthesize high-performance insulation retrofits to minimize heat loss and generate verified input parameters for energy compliance.

Building facade retrofit consultant

Ingest baseline EnergyPlus epJSON files containing Construction and Material objects.

Calculate baseline thermal transmittance (U-factor) across exterior wall assemblies.

Formulate insulation retrofit scenarios and update Material thermal resistance properties.

Validate modified epJSON files against the EnergyPlus schema and output retrofit reports.

Interactive thermal assembly configuration UI with layer thickness sliders and U-value calculators.

Use open-source EnergyPlus example files from the EnergyPlus GitHub release package or construct minimal epJSON mock files. Starter examples below are synthetic. They are not downloaded records.

EnergyPlus Uses EnergyPlus epJSON input schema definitions for Construction, Material:NoMass, and Material objects.

semantic-kernel, pydantic, jsonschema. Semantic Kernel facilitates structured reasoning plugins to validate thermodynamic formulas against schema definitions. Hosted reasoning model capable of accurate thermodynamic arithmetic and epJSON schema generation.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Calculates baseline and retrofit U-values consistent with ISO 6946 thermal resistance sums.

Emits compliant EnergyPlus epJSON Material and Construction definitions.

Prevents unphysical insulation thickness assignments exceeding practical wall cavity limits.
