Qwen2.5-1.5B BuildEng V7
Repository: Irfanuruchi/qwen2.5-1.5b-buildeng-v7-lora
This model is a building-engineering focused LoRA fine-tune of Qwen2.5-1.5B-Instruct.
V7 was made to move away from only direct engineering calculations and push the model more toward engineering reasoning behavior. Earlier versions could solve formulas, but still sometimes accepted wrong assumptions, bad unit conversions, unrealistic HVAC values, or incomplete design prompts.
The main goal of V7 was making the model more careful instead of just making it sound technical.
What Was Used
Base model:
Qwen/Qwen2.5-1.5B-Instruct
Training method:
LoRA fine-tuning with Unsloth
Dataset used:
buildeng-v7-15k
The dataset was generated using custom Python generators focused on engineering calculations, sanity checks, formula correction, and refusal behavior.
Main Focus Of V7
V7 focuses heavily on:
HVAC airflow reasoning, unit consistency, m³/h to m³/s conversion, duct sizing logic, formula correction. Engineering sanity checks, missing-input refusal behavior, ventilation reasoning and basic structural comparison logic
One major focus was teaching the model to stop giving confident answers when engineering inputs are incomplete.
For example, the model is trained to avoid:
• accepting wrong duct equations
• calculating ACH airflow from floor area only
• accepting unrealistic HVAC velocities
• guessing missing values
• confusing airflow units
Example Behavior
Example:
User:
7200 m³/h equals 7200 m³/s, right?
Assistant:
No. 7200 m³/h ÷ 3600 = 2 m³/s.
Another example:
User:
Calculate duct diameter.
Assistant:
More information is required before sizing the duct. Airflow and target velocity are needed.
Engineering Areas
The model was trained mainly around simplified building-engineering reasoning tasks including:
HVAC airflow calculations, duct sizing, ventilation logic, pressure reasoning
Hydronic sanity checks, footing pressure comparison, engineering unit conversion, missing-input engineering prompts
Limitations
This model is not a replacement for professional engineering software or real engineering review.
The training data is synthetic and simplified. Full ASHRAE, Eurocode, or professional design standards are not fully implemented.
Outputs should always be checked by a qualified engineer.
The model can still make arithmetic mistakes or produce incorrect engineering assumptions in some cases, especially on more complex problems.
Future Improvements
V7 is an intermediate version before larger datasets and stronger engineering models.
Future work includes:
• larger datasets
• stronger arithmetic consistency
• multi-turn engineering reasoning
• more structural engineering examples
• better HVAC design workflows
• larger engineering-specialized models including 32B systems
Training Notes
One interesting part during V7 development was that failed model outputs were analyzed and then turned into new repair-focused synthetic samples. For example, if the model repeatedly failed m³/h conversions or accepted bad duct formulas, additional targeted repair samples were added into later dataset versions. This made the tuning process much more iterative instead of just generating random engineering problems.
