1.0 LIGHTING DESIGN 1.1 CULTURAL WORKSHOP

First floor plan

The chosen space A is the cultural workshop, which located at the front

part of the building. It is strategic placed for its east sunlight reception

and high intensity of public attention. The ceiling height of this space is

3.4 metres. This space consists of 2 layers of facade, which

compromising an inner layer polycarbonate louver window panels, and

PVC fabric as the outer layer. The purpose of designing so, is to create

well ventilated interior, and the air gap between to allow the heat air

escape to the atmosphere.

Axonometric view of cultural workshop.

Daylight factor distribution as below, according to MS 1525:

R, average reflectance of space A 0.35 (grey unfinished concrete floor, exposed brick wall, grey unfinished ceiling) DF = 5.5 % The cultural workshop has a daylight factor of 5.5%, which is considered bright in MS 1525 guideline. The value of T is lowered down, due to its double layers of facade, and its semi-transparent, light transmittance quality, which is purposed to avoid the excessive reading of daylight factor, which may created discomfort to the users.

1.12 ARTIFICIAL LIGHT PROPOSAL However, there is a need for the usage of artificial light as it gets darker over the time. The advantage of doing so, is that users are able to turn it on or off when there is a necessity. Plus, the site is behaved as shophouse typology, which it has a long front-to-back stretched area, which the light hardly transmitted to the middle. The only light can enters via roof or front and back facades. The required lux level for the workshop in MS 1525 is around 400 lux. Recommended light source:

1.13 PSALI SCHEME PSALI by simply known as Permanent Supplementary Artificial Lighting of the Interior. It aims to integrate the daylight with the electric light , where windows are constrained its role as admitters of daylight. Therefore the usage of electric lighting to supplement the daylight in the interior parts of the room when there is a necessity.

12 LED luminaires can be controlled by 3 switches respectively. Each row of lights can be manipulated depends on the change of daylight

factor in different time.

Row 1 been switched on, during 11am to brighten up the rear part of the workshop.

All rows of light been switched on, during 3pm to brighten up the rear

part of the workshop.

1.2 BOOK STORAGE

Third floor plan

Section of Space B

The chosen space B is the book storage section. Since it is away from

both facades that welcomes the daylighting, it is necessary to have

artificial lighting to fulfill its brightness requirement in MS 1525, which is

around 300 lux. The ceiling height of space B is 3.2 m.

Recommended light source:
