Method — Screening-level estimate
Air volume and cooling load are floor-area ratios. This is NOT a psychrometric, equipment-selection or duct-sizing calculation.
Every result below is produced by the same engineering engine that feeds the High-Rise reference project, so a quantity taken from this page and a quantity taken from the workflow cannot disagree.
Governing Formula
Governing Formula
Q = A x h x n Where:
-
A= Conditioned floor area [m2] -
h= Ceiling height [m] -
n= Air changes per hour [1/h]
Derived Equations:
Cooling load in kW:
Q_kW = A x w / 1000 One air handling unit per floor:
AHU = floors Total ductwork run:
L_duct = A x ratio Assumptions & Limitations
- No psychrometric properties, no sensible/latent split, no fresh-air or filtration load.
- Duct sizes are not derived - no velocity or pressure-drop calculation.
- No heat-pump, chiller or plant selection; use the Electrical Supply calculator for the demand side.
