Calculation detail

Formula: Cooling load = conditioned area × design load density

A simple area-based estimate is used to establish an initial cooling-load allowance.

FORMULA VERIFICATION

Units, scope and reference

Reference: ASHRAE Fundamentals preliminary load-estimate context.

Internal unit basis: m², W/m². Outputs: kW, TR.

Valid conditions: Positive conditioned area and explicitly selected load density.

Limitations: Screening estimate only; not a room-by-room ASHRAE load calculation.
