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
