Multi-Zone Commercial Load Worksheet

Structured worksheet aggregating envelope, lighting ($\text{W/ft}^2$), occupant, and ventilation loads.

Commercial Total Load Equation:

$ Q_{\text{total}} = (\text{Area} \times f_{\text{cooling}}) + (N_{\text{occ}} \times 400) + (W_{\text{lighting}} \times 3.412) + Q_{\text{equip}} $
