This document summarizes the lighting and acoustic design considerations for a market located along a main road. For lighting, the café and outdoor area have sufficient natural light during the day to reduce energy usage. The office on the second floor requires artificial lighting since it has no windows. For acoustics, calculations show the material selections will reduce noise transmission to recommended levels for the kitchen and office, providing comfortable environments.

SITE INTRODUCTION
The 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.

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.

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.

REVERBERATION TIME
GROUND FLOOR CAFÉ KITCHEN SECOND FLOOR OFFICE
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.
