4.3.Artificial lighting

From the layout, the red color columns with a very bright daylight distribution consist of all openings

and artificial lighting in the gymnasium space. This is because the openings and under the artificial

lighting are constantly exposed to the natural lighting making the space brighter than other parts of

space. The light distribution gets lower as it further away from the light exposure. Away from the

openings, there is an empty concrete wall with no openings and lack of lighting alternative in this part

of space hence the light exposure decreases significantly. Affecting the visual colored layout, it is

shown that from the yellow coloured column with a bright light distribution into green with fair

amount of light distribution and lastly the gray column with poor light distribution. Overall, the

daylight factor of the gymnasium is average in performance since the parts that are exposed to the

daylight illuminant are inconsistent.

4.3. Artificial lighting

The SOCSO Rehabilitation Centre gymnasium does not rely only on the natural sunlight. Artificial light is needed as an alternative light during limited sunlight especially during night time. There are few types of artificial lights used in the gymnasium not only for design and visual purposes but the lights also provide thermal comfort to the space as it is also one of the keys for controlling the temperature, view clearing and brightening up the space. Since this is a gymnasium, too many lights could affect the temperature, making it uncomfortable for the users. While too little artificial lights could prevent the users to see clearly especially in the gymnasium that is full of heavy and dangerous equipment that creates accidents. With the consideration of space, environment and users the artificial lights in the gymnasium need to be controlled in numbers as it is more preferable.

The gymnasium uses Philips Lighting Brightboost TLF-T8 + tubes as their main artificial lights. This lighting offers a long life energy savings and environmentally responsible light bulbs. There are 5 units in a row of light fitting that covers both walls of the gymnasium space.

From the figures above, it is shown that the artificial lights are arranged on the front rather than the

back part of the space. The reason is that the lights focus on the main active area of the space which is

where all the gymnasium equipment is located. This creates an illusion that the area and activities

there are more dominant than other areas. While the back part of the gymnasium is used as a resting

and yoga area that require dimmer lights which is the reason the back area has a low number of

artificial lights that results in mild brightness.
