Translate heat loads into estimating assumptions that affect equipment counts, line sizes, and commissioning hours. Confirm design temps, ambient conditions, defrost methods, and usage profiles to avoid under/overstating your scope.

• Design Temps & TD: Box/case temps, coil TD, and space ambient drive BTUH.
• Load Drivers: Envelope, infiltration/door openings, product pull-down, people, lighting, defrost heat.
• Diversity: Not all circuits peak simultaneously—apply realistic factors to labor and power allowances.

1. List Zones: Coolers, freezers, prep areas, specialty cases—capture design temps and duty cycles.
2. Defrost Impact: Off-cycle vs electric vs hot gas affects BTUH and electrical placeholders.
3. Ambient Assumptions: Roof equipment/utility rooms—note summer/winter design used by engineer.
4. Estimating Links: Higher loads → larger pipe sizes, more fittings, more commissioning time.
