Wireless Sensor and Actuator Networks for Lighting Energy ...

system could be reallocated to operating the air conditioning system, which in turn
diminishes the actual amount of energy savings.
A BMS has the potential of providing higher-level supervisory control to
optimize the energy usage among all the building systems. The current research lighting
system needs to be made compatible with the BMS, and be capable of communicating
with other electrical systems such as the heating, ventilation and air conditioning
(HVAC) system for maximum possible energy savings.
10.3.5 Application of the Proposed Framework in Other Domain
Although targeted at generating energy savings from the fluorescent lights in
commercial office buildings, the same framework could possibly be employed by other
applications with reasonable revision and extension.
Stage and theater lighting systems could potentially benefit from the intelligent
lighting control framework. Being another lighting application, the requirements of
lighting in the art and entertainment industry are very different from that in office
buildings. Energy conservation may not be a priority, but other parameters such as the
color and incident angle of light, background lighting, etc. can be critical in addition to
the illuminance at the targeted area. Furthermore, the lighting fixtures could be moving
or rotating along with the performers or in accordance with the scenes. Intelligently
coordinating the wireless sensors and lighting actuators in real time to deliver the
optimal lighting may revolutionarily simplify the current stage lighting control while
retaining the same or even better results.
