build.hvac-btu-cooling Calculator
Calculates cooling load in BTU/hour and converts to tons of refrigeration from room dimensions, occupancy, solar exposure, and insulation. Undersized AC can't reach setpoint on hot days; oversized units short-cycle and leave humidity uncontrolled.
Inputs
Area
Two-dimensional surface extent (m²). For complex shapes, break into simpler sub-shapes and sum.
Height
Vertical measurement. For health calculators, typically standing height without shoes.
Sun
Reference formula or conversion factor shown for context.
