Building occupants prefer spaces with good daylight distribution for their living and working spaces. It is particularly important in a workspace that sunlight is present for indoor illumination in order to affect worker satisfaction, performance, and productivity. It could be a disadvantage for optimal visual conditions to have a lot of daylight available in the building, not only because of psychological reactions to too much sunlight, but also because of the change of daylight properties over time. Natural daylight in a building such as workspace is highly detrimental to the productivity of the occupant and possibilities to the performance of an organization. In a tropical climate, the sky is predominantly intermediate, with inconsistent clouds, which will influence the amount of direct sunlight and daylight available.
