“ INTRODUCTION TO

ELECTRIC SYSTEM “

‘ Energy efficient , Lighting System’

The main function of electrical distribution system is to provide electrical power from the local, Tenaga

Nasional Sdn.Bhd (TNB),to the building. It consist of the switchgear, transformer Main Switch Board
(MSB). It must be maintained by the qualified person in electrical engineering known as KCJ

Engineering

DAYLIGHT RESPONSIVE CONTROL

The general lighting system is designed to be daylight responsive in the most optimal way as to

maximize daylight usage. This means reducing the lighting energy consumption as much possible

ensuring visual comfort for occupants. The lighting control strategy installed for MKR in the day-lit

zone are:

Manual on - The light only switches on when occupants press the switch

Automatic off - The light switches off automatically when there is enough daylight measured by a light
sensor.

The reason for the ‘Automatic on’ and ‘ Automatic off’ control strategy is for energy efficiency really

require and ask for it. The reason being that most people can work at level below the code

requirement of 300lux and if not in use they can switch on their individual task light instead of having

all the general lighting to be switched on

30% OF SPACES DAY-LIT

At least 30% of the building will be day lit. The day lit environment does not require the electrical light

to be switched on, which is partly due to the very transparent interior design of the building. Daylight
is thus entering from the façade. This gives a pleasant working environment for the occupants while

saving energy as well
