| Summary: | The global warming issue and the limitation of unrenewable energy resources create
issue of the importance of energy conservation in the building. Solar energy resources in
Indonesia has a potency to be used as natural daylighting in building architecture, mostly in
high rise building to support saving energy building. Light shelf is one of passive strategies
of solar resources utilizing in building. Light shelf has a characteristic to reflect the daylight
to the ceiling so that its distribution can be more uniform to the room interior.
This research is aimed to find the most optimum light shelf design based on variables
that are proceed such as dimension and angle of interior light shelf and also the position of
light shelf height that affect on the conventional window dimension ratio to clerestory
window as the entrance of daylight into the room. The research was limited to the specified
parameter such as location in Jakarta city, office building, time, dimension, and room
reflectance and the orientation as the input data in the simulation using Dialux©. Quantity
analysis method based on the optimum light criteria by light shelf such as illuminance which
fulfill the optimum room standard criteria 200-500 lux, homogenous diffuse and uniformity.
The result of the research showed that light shelf effectiveness is influenced by
dimension, angle and clerestory window on the light shelf as the most effective design is the
the 1,2 m dimension, angle 5o and height 2,0 m or clerestory 0,8 m dimension. The most
influential variable is light shelf height or clerestory dimension continued with angle and
dimension of light shelf. Light shelf design that recommended is the 0,9-1,2 m dimension,
angle 0o-5o and height 2,0 m or clerestory 0,8 m dimension. This recommendation is
presented in a prototype formed light shelf mock up. |
