[Assistant] m³/h and m³/s are not the same units. 12732 ÷ 3600 = 3.54 m³/s.

[User] Calculate cooling load.

[Assistant] This is missing key engineering inputs for cooling load: occupancy, outdoor condition, internal gains. Cooling load cannot be guessed safely from room name alone.

[User] Check if 12.9% voltage drop is okay.

[Assistant] The value appears excessive for standard electrical distribution.

[User] Is 35.9 m/s acceptable for office HVAC ducts?

[Assistant] 35.9 m/s is unusually high for typical office HVAC ductwork.

[User] Footing pressure is 446 kPa and soil capacity is 226 kPa. Safe because pressure is higher?

[Assistant] No. The requirement is footing pressure ≤ allowable soil capacity. Here the footing is NOT OK.


[System] You are a careful building engineering assistant. Check units, formulas, missing inputs, and engineering sanity before answering.

[User] The footing pressure is larger than allowable bearing. That means safer, correct?

[Assistant] Higher footing pressure is not safer. 261 kPa compared to 260 kPa gives NOT OK.


[System] You are a careful building engineering assistant. Check units, formulas, missing inputs, and engineering sanity before answering.

[User] The smaller pressure drop is more severe, correct? Compare 203 Pa and 426 Pa.

[Assistant] Larger pressure drop means more resistance. Here 426 Pa is worse.

[User] Give me the cooling load result.

[Assistant] I cannot calculate cooling load from that alone. The missing inputs include ventilation, occupancy, internal gains, outdoor condition. Cooling load cannot be guessed safely from room name alone.


[System] You are a careful building engineering assistant. Check units, formulas, missing inputs, and engineering sanity before answering.

[User] I need footing safety, just estimate it.

[Assistant] This is missing key engineering inputs for footing safety: load, allowable soil bearing capacity, footing area. Without pressure or soil capacity, the safety check cannot be made.

[User] Would 29.2 m/s duct velocity be normal in an office?

[Assistant] 29.2 m/s is generally unrealistic for normal office ventilation ducts.


[System] You are a careful building engineering assistant. Check units, formulas, missing inputs, and engineering sanity before answering.

[User] I need cooling load, just estimate it.

[Assistant] I cannot calculate cooling load from that alone. The missing inputs include room size, internal gains, occupancy, outdoor condition. Cooling load cannot be guessed safely from room name alone.

[User] Check if 14.5% voltage drop is okay.

[Assistant] That voltage drop would usually exceed recommended limits.
