How is this calculated?

The coating lowers the indoor air temperature the AC must hold, so each volume of air handled is cooled by a smaller ΔT. The continuous sensible load avoided is:

Q (W) = ρ × V × ACH/3600 × c_p × ΔT

with air density ρ = 1.2 kg/m³, specific heat c_p = 1005 J/kg·K. Electricity = thermal load ÷ COP, integrated over operating hours × days. Cost = kWh × tariff; CO&sub2; = kWh × grid factor.

Indicative estimate only. Real savings also depend on solar exposure, roof/wall U-values, insulation, humidity (latent load) and AC sizing. This model counts the sensible-cooling reduction from ventilation/infiltration air at the chosen ΔT. For a validated figure, consult JAT Holdings / an energy auditor.
