In the University of the Philippines Diliman

In the University of the Philippines Diliman, the College of Architecture conducted a case study that will implement the Daylighting design in the College of Architecture’s Library. There are two daylighting elements that is now included in the actual design of the library based on the results of the simulation tests that was conducted – the two elements are sunshades and skylight. It was proven that the two elements were applicable for the standard that was set in order for the library to be illuminated accordingly. Overcast conditions must be simulated in order to lessen the amount of glare inside the building and windows must be modified in accordance to the desired opacity that will lead to a controlled admission of daylight. (Chua, J. ; Flores-Bernardo, R., n.d.).
Through the use of regression analysis in a computer simulated program, the effects of window systems on the electrical usage of buildings in 5 common climates in Asia have been studied that resulted to a recommendation in a design guideline for window systems that can help buildings become energy-efficient. For the window to wall ratio (WWR) of buildings in Manila, the most energy-efficient orientation would be on the north-face of the building with a 50% WWR; for the second option, it is the south-face of the building; for the third option, it is the
west-face of the building, and for the fourth option, it is the east-face of the building with a
WWR of 25% as an effective energy saving window system. (Lee, J.B., Lee, J.W., Jung, H.,
Park, J., Yoon, Y., 2012)
The science behind daylighting design focuses on providing enough daylight for an occupied space while reducing or even completely eliminating risks of undesirable side effects. It involves careful balancing heat gain and loss, glare control, and variations in daylight
availability. Some successful daylighting designs consider the use of shading devices to reduce
glare and contrast in the workspace. Additionally, window size and spacing, glass selection,
reflectance of interior finishes, and position or location of interior partitions should be evaluated
(Ander, 2016).
