The applied lighting control strategy determines the basic methods used to
control the environment. When formulating an overall strategy, there are some
basic considerations:.
New construction and major renovations provide the opportunity to
easily run control cables from user interfaces to the control processor
when the walls are open.
Existing construction or minor renovations often make the task of
running cables more difficult, time consuming, expensive, or even
impossible (in historic landmarks, etc.). In this case, you may choose
to install a partialyl or completely wireless system
Light level control is achieved through dimming controls and daylight
management, where applicable, to adjust the lighting to the
appropriate level for different occupant activities
Occupancy sensing is used to switch the lighting on and off,
independent of time intervals or scheduled periods. This allows the
space to be responsive to individual use, and conserves energy
Scheduled lighting is determined by time of day, day of week,
vacation, outdoor lighting, and safety lighting requirements. An
astronomical clock (programmed with sunrise and sunset information)
is often used to provide natural lighting transitions
HVAC control should be part of the overall control strategy, permitting
additional economic and convenience benefits
