Mechanical Load Calculation Review Agent
Independently reviews HVAC and mechanical engineering load calculations against building envelope data and code requirements to catch sizing errors before equipment procurement.
Mechanical engineers manually calculate heating and cooling loads using building envelope, occupancy, and equipment data, and a data entry error or missed load component such as internal gains or infiltration can lead to significantly oversized or undersized HVAC equipment, driving wasted capital cost or comfort complaints after occupancy
Second-checking these calculations is time-consuming and often skipped under deadline pressure
This agent independently recalculates heating and cooling loads using the same building parameters, compares results against the submitted calculation, and flags discrepancies before equipment is specified and ordered
The agent ingests building envelope data, occupancy schedules, internal load assumptions, and climate design data referenced in the mechanical engineer's load calculation, then independently computes heating and cooling loads using standard ASHRAE methodology. It compares its results against the submitted calculation output room by room and system by system, flagging discrepancies beyond acceptable tolerance and identifying likely root causes such as missing infiltration values or incorrect glazing U-factors. Findings are compiled into a QA report for the mechanical engineer's review before equipment sizing is finalized.
