Useful BTU Cooling Formulae:
Equipment BTU = Total wattage for all equipment x 3.5 Lighting BTU = Total wattage for all lighting x 4.25 Total Occupant BTU = Number of occupants x 400 Room Area BTU = Length (m) x Width (m) x 337 Total Heat Load = Room Area BTU + Total Occupant BTU + Equipment BTU + Lighting BTU
