Reference: Energy and Atmosphere Credit, Optimize Energy Performance-Lighting Power, Calculations

A 30% reduction can earn 4 points.

The percent reduction is calculated as:

Percent reduction = Lighting power reduction (watts) / Interior lighting power allowance (watts)

The lighting power reduction = Interior lighting power allowance (watts) - Installed interior lighting power (watts)

Lighting power reduction = 25,000 watts - 17,330 watts = 7,670 watts

Percent reduction = 7,670 watts / 25,000 watts = 30%
