Benchmark:1. Using optimum natural lighting, so that, the minimum of
30% occupied area reaches at least 300 lux 2 points.2. One point awarded for having lux censors to automate
artificial lighting, once daylight is under 300 lux 2 points.
Aim:To encourage the use of adequate daylight to reduce energyconsumption and recognize building designs which optimizedaylight.
