The document provides details on the lighting and acoustic design of a proposed community library in Sentul, Kuala Lumpur. It includes: 1. An introduction describing the library as having an area of 1800-2000 sqm and serving to engage the local community. 2. Calculations for the artificial lighting design of a discussion room and cafe area within the library, determining the required number and layout of light fixtures. 3. Calculations of the reverberation time for the discussion room and sound reduction index for the cafe to evaluate the acoustic performance of the spaces.

Hence the intensity is the highest According to diagram above, it shows that from blue to yellow represents the intensity of light from low to high and the brightest is in the middle of the cafe as there will not receive any natural daylight. Hence, the artificial lights focus on the middle part of the cafe.

As the discussion room receive natural daylight from 3 faces, the natural daylight that penetrate will lit up half of the discussion room. According to MS1525, discussion room requires 150 Lux and therefore min 5 nos of lights are required. For this discussion room, there are 6 nos of lights placed and controlled by two switches. During daytime, as half of the discussion room will receive the natural daylight, only switch 2 is switched on to get enough luminance for the discussion room. During night time, the space will not get any natural daylight so all of the lights are switched on. This layout arrangement for the lighting is to reduce the amount of energy waste to lit up the room during day.
- 12. Building Science 2 Project 2 Integration Project Chia Wee Min 0315186 2.5 PSALI FOR CAFE ( FIRST FLOOR ) For cafe, there are 3 switches controlling the lights . during daytime, switch 1 and switch 3 can be switched off as there are natural daylight penetrating into the space. As for night time, all the lights are on as there will be no natural daylight penetrating into the space. Lighting arrangement for cafe. As the cafe receive natural daylight at the front and back , the natural daylight that penetrate through will lit up the front and back part of the cafe while the middle part of the cafe will receive minimum daylight. According to MS1525, cafe requires 100 Lux and therefore min 17 nos of lights are required. For the cafe, there are 18 nos of lights and 3 switches controlling 6 light each.

Normal speech is inaudible 55 dB or greater Very loud sounds, such as loud singing, brass musical instruments or a radio at full volume can be heard faintly or not at all. According to the general sound environment, the value is categorized as less than 35dB which is loud according to the normal conversation and can be heard distinctly through the walls. This cafe spaces uses variety of materials such as concrete, glass, and aluminum. To be able to achieve better acoustic absorption, the balance use of effective materials is important, it helps the overall reduction of sound transmission between spaces.
