Cooling saving from reduced lighting calculator

Only lighting savings coinciding with cooling produce this cooling-energy saving.

E_{\text{AC saved}} = \frac{E_{\text{lighting saved during cooling}}}{\mathrm{COP}}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

E_{\text{AC saved}} = \frac{100}{4} = 25

Symbol	Meaning	Unit
$E_{\text{AC saved}}$	cooling electric energy saved	kWh
$E_{\text{lighting saved during cooling}}$	reduced lighting heat during active cooling	kWh
$\mathrm{COP}$	cooling performance	—

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
