BUILDING SCIENCE 2 Integration with Design Studio 5 LIGHTING

SITE INTRODUCTIONThe site is located along the main road Jalan Tuanku Abdul Rahman near intersection with Jalan

Haji Taib.

The market consists of café, fruit & salad bar and stalls selling local food, bringing together all types

of famous local food under one roof to attract tourists from other places other than families that are

living nearby.

The market is oriented to the east causing its exposure to the morning daylight. However, the site is

surrounded by buildings of 3 or 4 storeys high with few high rise building opposite the site. In the

morning, the problem is reduced because of the shade provided by the high rise opposite.

The picture shows the shadow pattern causes by the opposite buildings in the morning.

SELECTED SPACES FOR LIGHTING ANALYSIS

GROUND FLOOR CAFÉ

FIRST FLOOR OUTDOOR AREA SECOND FLOOR OFFICE

The idea of the market is to have an open plan to allowed

the spaces in the building to be seen and by that to attract

visitor to go into the market.

On the ground floor, the café has sufficient daylight to

lighten up the space and create warmer tone on the food

to make them seem pleasing. Artificial lighting is not

required during the day so energy can be saved.

The outdoor area on the first floor is only shaded by the glass façade

with sunscreen. This is to provide immediate visual to the public on the

monorail train. The daylight shining into the space is also enough for

activities to happen there. Usage of artificial lighting can be reduced

to save energy.

On the second floor, the office, has no openings and has to depend

purely on artificial lighting for the space to function well. Lumen

Method has been used to calculate the number of luminaires

needed to light up the space. 8 luminaires are needed with an

array of 2 x 4 for uniform distribution.

Conclusion

The café and the outdoor area need artificial lighting if they

operate at night. Cost of operation can be cut down with

lesser energy usage during the day.

28.8 dB of noise will reduced during the sound transmission from the traffic on the street to the kitchen area. The selection of material to reduce unnecessary noise transmission is enough the isolate the space from adjacent noise source. By meeting the requirement, staff will be more comfortable working in the kitchen.

The reverberation time for the kitchen during peak hour is 0.546s which has met the standard reverberation time (1.2 – 1.5s) according to the Acoustic Standard ANSI (2008). The selection of material is suitable for the kitchen area for a comfortable working environment.

The reverberation time for the office during peak hour is 0.734s which has met the standard reverberation time (1s) according to the Acoustic Standard ANSI (2008). The selection of material is suitable for the office area for a comfortable working environment.
