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.
