synthetic-hvac-engineering-precheck (v0.1)

Scope

Programmatically generated Q/A pairs for building-services quick checks (HVAC/hydronics). Focus is on:

• —unit hygiene (explicit conversions)
• —deterministic equations and step-by-step workflows
• —basic sanity checks and “missing inputs” prompts

This is pre-design / pre-check material. It is not a substitute for code-compliant design or professional sign-off.

Data

Each row is a JSON object with a single field:

• —text: a single string containing <|system|>, <|user|>, <|assistant|> blocks.

The assistant responses are formatted to include:

• —Given
• —Assumptions
• —Steps/Equations
• —Result
• —Sanity check
• —Next info needed

What’s in it

Generated tasks include:

• —steady-state heat loss: P = U·A·ΔT
• —round duct sizing from flow + target velocity
• —ventilation flow from people rate
• —hydronic flow from load + ΔT: P = ρ·cp·V̇·ΔT
• —pipe ID pre-sizing from flow + target velocity
• —unit/constraints traps and missing-input checks

Provenance

All samples are synthetic and produced by deterministic Python scripts (parameter sampling + closed-form calculations). No real project data or proprietary sources.

Files

• —train.jsonl
• —valid.jsonl

Limitations

• —simplified physics (steady-state, idealized assumptions)
• —not tied to any specific standard (ASHRAE/EN/ISO) or manufacturer data
• —unit-sanity/trap coverage is partial in v0.1 (expanded in later versions)

Version

• —v0.1: initial release
