The idea behind occupancy control is simple
and elegant: use a sensor to determine when people are in the vicinity,
and reduce or eliminate unnecessary lighting if areas are empty.
Occupancy control systems provide convenience, security, and cost and
energy savings. Many of today's commercial lighting and building
automation systems have already begun to use occupancy sensors to turn
lights on and off based on whether or not an area is occupied. The
California Energy Commission estimates that using occupancy sensors to
turn lights off when areas are unoccupied can reduce energy waste and
costs by up to 45%.
Not only does occupancy control reduce energy consumption and save
money, it also helps buildings to comply with the "automatic shut-off of
building lighting" requirements of energy codes such as ASHRAE 90.1 and
California Title 24.
Daintree Networks enables a complete and powerful occupancy control
solution, through the use of wireless occupancy sensors. In addition to
simply turning lights on when someone enters a room and off when they
leave, the combination of occupancy and task tuning controls enable
specific illumination levels to be set based on individual needs. For
example, turning lamps on at 85% (instead of 100%) is a difference very
few people will notice, and can reduce energy costs while improving the
life of the lamps.
Daintree-based systems can also combine occupancy control with other
cost-saving strategies, such as scheduling and daylight harvesting, to
further add to savings. And Daintree supports manual over-ride, which
allows occupants to brighten (or dim) pre-set levels when they are
performing tasks that require more (or less) illumination.
One of the benefits of wireless controls is the ease of adding or
moving sensors to fine-tune the system or collect more granular details
about occupancy levels. Daintree-based systems also automatically
identify new sensors, and intuitive tools make it easy to configure,
manage and monitor your lighting system.
