Optimalisasi Pencahayaan Alami pada Ruang

Abstract

Abstract Natural lighting is the lighting obtained from direct sunlight, where the light is obtained in the morning
until late afternoon. According to SNI 03-2396-200, natural lighting during the day can be good in a span of solar
orientation starting at 8:00 pm until 16: 00 pm with equitable distribution of incoming light in the room and did
not leave annoying glare effects in the use of lighting natural, regardless of the quality and distribution of light
that enters the building through a window and orientation of openings. The wider the aperture, the more light that
enters the room. It is necessary to control the amount of light coming into the room. The research used is
quantitative method by using mathematical models, with the measurement process, using a formula to obtain
accurate data. The object of research and observations in Architecture Program Faculty Building University of
Malikussaleh, Lhokseumawe Aceh. Observation is by direct observation to see the condition of natural lighting in
classrooms, measurements the extent of the classroom. Then collect some measurement data among other things,
measure the light intensity at the lecture hall by using Luxmeter, calculate the intensity of light at the lecture hall
by factors sky with measuring point main and the measuring point side and the comparative results of the
measurement of light intensity of the lighting level the average recommended. The results show, a lecture hall in
the building Prodi architecture has three floors, which have 4 lecture room on floors 1 and 2, 2 room studio
regular on floors 1, 2 lab computer room on the floor and 2 studio design room on the 2nd floor. also of course
the building also has other equipment such as administration room, warehouse and other supporting facilities.
But for the third floor untapped dikarenaka still in the process of renovation. The results of observations obtained
intensity of natural light on the 1st floor and 2nd floor Architecture Program building University of Malikussaleh
based on the measurement of light intensity using the luxmeter, the obtained data is that the rooms was not in
accordance with the standards of an average lighting is recommended by ISO 2000 for classrooms -03 250 lux
and 700 lux.
