3. Lighting and Control: Benefits
the right
amount of light where
it is need and when it
is needed
the right light intensity
based on requirements
zoned to
ensure it is only used
where it is needed,
reducing energy
consumption
ensure lighting
only operates when it is
needed, eliminating energy
waste

lecture and A/V teaching
methods
Occupancy sensors turn
the lights OFF when the
space is unoccupied
A photo sensor and
dimming ballast provide for
teacher control and daylight
Harvesting/ dimming

10. Lighting and control: Types of control
Occupancy sensors
serve three
basic functions:
1. To automatically
turn lights on when a
room becomes occupied
2. To keep the
lights on without interruption
while the controlled space
is occupied
3. To turn the lights off within a
pre-set
time period after the space has
been vacated

12. Lighting and control: Selecting and considerations
Step 1: Room survey
• Size,
• Levels of natural light,
• Natural corridors,
• Qty of detectors needed
Step 2: Type on control
• Auto, semi auto,
• override,
• remote control,
• wall switches
Step 3: layout of lighting
connection
• Switching requirements
Step 4 Installation
• control function requirements
• sequence of operation,
• programming and set-up

13. Lighting and control: Commisioning
Final adjustment, calibration,
and tuning of the various
components
Programme "burning in"
Programming weekday, weekend,
occupancy schedules.
