of the building to improve the distribu- tion of light distribution, depending on
the width and height of the room, and the location of lighting openings.
Multilateral lighting, openings in some of
3. the more than two sides of the building,
can reduce glare and contrast, improve equitable distribution of light on hori-
zontal and vertical surfaces, and provide more than one main zone of natural light-
ing. Clerestories, the top window with a
4. height of 210 cm above the loor, is a good
strategy for local lighting on horizontal or vertical surfaces. Placement openings
high on the wall of light can provide a deeper penetration of light into the build-
ing. Light shelves, providing imagery to the
5. position of the window being, separate
glass to view and glass for lighting. Can be an external element, internal, or a com-
bination of both. Borrowed light, lighting concepts shared
6. between two adjacent rooms, such as cor-
ridor lighting obtained from the transpar- ent partition space next to it.
To ind out how much light coming into the room as a reference qualiied or not, and
how to measure it can use Luxmeter tool in every corner of the room in a test.
Diagram provides information on the solar azimuth and height mataharipada any
time throughout the year. The slope of the Earth’s axis ixed, the northern hemisphere
will be facing the sun in June and the south- ern hemisphere would be facing the sun in
December.
Extreme conditions will occur on June 21 when the north pole is closest to the direc-
tion of the sun and on 21 December where the north pole is at its farthest from the sun.
On September 21 and March 21 the sun was right above the equator Lechner, 2007. So
that the most effective time to conduct test measurements sunlight is three 3 hours pri-
or to 12.00, 12.00 and after 12.00.
4. Standard Distribution Lighting
Based on SNI 03.6575.2001, minimum lighting levels on its recommendation to the
various functions of space shown in the ta- ble:
Methods
This study evaluates the lighting distri- bution process through the data retrieval with
the aid of a luxmeter on the object of study. The data can be analyzed to see the distribu-
tion of illumination in the room. This method is useful to estimate the MS Excel program is
to create a mathematical equation “Intensity- Based Distribution Squared Distance”.
1. Lux meter digital HS 6612 Dekko
Lux Digital Meter HS 6612 dekko is one tool type gauges the intensity of light or light-
ing levels used in this study. The lighting re- quirements of each room is sometimes differ-
ent. All depends and adapted to the activities undertaken. To measure the light levels need-
ed an instrument that could work automati- cally capable of measuring light intensity and
adjusts the light required. This tool can dis- play the measurement results using a digital
format. Different types of light entering the
luxmeter either natural or artiicial light will have a different response from the sensor.
Various colors are measured will produce different color temperatures and different
wavelengths, the value generated by luxme- ter of the numbers called illumination. Mea-
surement unit of study done at 08:00, 12:00 and 15:00 by using natural lighting where the
sun shines bright light conditions.

3.1. Objects Study
Study data collection that are in one of the rooms, studios, apartment buildings Puncak
Kertajaya Surabaya, located on the 8th loor, orientation longest building on the north and
south. The room was on the ield in a tower with a view to the south. Height of the rooms
from loor is 21 meters from the ground loor where height is 3 m per loor, on the loor
of the apartment no 4 was removed, then the actual position of the object of study are at
the 7th loor.

Figure 2. Typical apartment building mass
Characteristic studio type rooms on the study object has an area of 18 m², ceiling
height of 3 m, has two windows with clear glass on the south ield with an orientation
toward the inside of the inner court of the building mass tower. The rooms have white
color made standard on the ceilings, loors and walls. In this studio-type unit has one
bathroom and a small kitchen that is located between the entrance. This unit also has a
small balcony the size of 1:25 m x 0.85 m. The size of the two windows on the type, measur-
ing 0.60 m x 1:50 m window position 0.5 m
from the loor on the side wall of the balcony section and measuring 0.75 m x 0.80 m win-
dow position 1m from the loor on the side wall next to it.
3.3. Partitioning Grid and Point Study Sample
To deine and facilitate decision-sam- pling point in the room, indicated by per 1
m² coordinates and the coordinates of each point within 1m. Giving the name of the mea-
surement point will make it easier to deter- mine the test point by using the symbol T1 -
T13. Recording the value of strong light lux luxmeter premises was conducted in March.
Because in the months of March, June, Sep- tember, December, this is the maximum of
sunlight is shining, and done after the simu- lation will be visible results which parts of
which get maximum light and which part is not getting light to the maximum.
Large Lux in each coordinates will dif- fer from each other because of the incoming
light will be very different because of the fu- ture then the light will be brighter, if more
and more into the light that may be on the
wane. It is inluenced also by the exposure time and the weather.
Lighting distribution on the study was also inluenced by the position and typical
windows. For more details can be seen in the image below:
