1.0 Introduction
This Project aims to understand the integration of the light principles into the consideration of designing a library which helps to achieve optimal visual comfort for the users. Students would be able to design spaces incorporating artificial and day lighting thus producing a sustainable design.
The picture above shows the site plan of Jalan Tuanku Abdul Rahman facing the east, in front of the main road.
2.0 Lighting
Daylight Factor It is commonly used to determine the ratio of internal light level compared to external light level and is defined as following equations:
DF
Ei 100% Eo
DF = Daylight Factor Ei = Illuminance due to daylight at point on indoor working plane Eo = Simultaneous outdoor illuminance on a horizonal plane from an unobstruct hemisphere of the overcast sky
AverageDF
W T A (1 R )
Average DF = Average Daylight Factor W = Area of the windows A = Total Area of Internal Surfaces T = Glass Transmittance θ = Visible Sky Angle R = Average Reflectance
