As the late afternoon approaches, the heat is high, and it's not practical to still rely on natural light. The curtains close, the AC can increase to more ambient temperature, and the lights can turn on at maybe 50% brightness. During the evening, the lights can automatically brighten to their set maximum. The AC further increases to counter the cooler evening weather. The curtain status can be maintained manually as per requirement. This again is just one example of how an office can utilize smart office automation to create an intuitive setup that works with changing weathers, seasons, times, and the number of employees to create an environment that while comfortable, is never wasting any electricity. Savings can be as high as 30-35% if automation is incorporated properly.
