How this calculator works
Enter floor area (m²), heat gain factor (w/m²), occupants, heat gain per occupant (w), design margin (%). CalcStack applies the displayed formula and reports each intermediate planning value with the units shown.
Formula / method
Sensible load ≈ area × heat-gain factor + occupants × heat gain
Worked example
Use the documented default inputs to model hvac cooling load calculator.
Assumptions and limitations
Inputs represent stable average operating conditions and the displayed equation applies.
This is a planning model; real systems and measurements can require domain-specific corrections.
