Today s architecture tends to Minimizes negative environmental impacts of buildings and

Promotes sustainable design. Saving energy and the efficient use of renewable energy

resources is one of the main strategies in sustainable architecture, and building design success

is characterized by its ability to minimize energy consumption and depend on renewable

energy sources like daylight and sun.

Daylight provides high illuminance and permits excellent colour discrimination and colour

rendering. These two properties mean that daylight provides the condition for good vision.

But, daylight can also produce uncomfortable solar glare and very high-luminance reflections

on display screens, both of which interfere with good vision. Thus, the effect of daylight on

the performance of tasks depends on how the daylight is delivered. It also can increase heat

loads. All of these factors need to be considered in daylighting design for buildings.

Using Daylight responsive controls in nonresidential buildings can have significant benefits

for saving energy.

This paper aims at identifying Daylight responsive controls systems and its role in saving

energy in nonresidential buildings, to help architecture choose the most convenient system to

their designs.
