When the city skyline
is lit up at night, it may make a pretty sight, but lighting up those
empty buildings comes at a high price. Lighting
typically accounts for up to 40% of the electricity used in commercial
buildings, and the cost of that power is creeping up
year by year.
One of the easiest ways to reduce energy use and cut costs (and
emissions) is to turn off lights when they are not
required, and the most reliable way to do this is to automate the
process. Many of today's lighting control and building
automation systems provide time clocks which automatically turn on, off,
or dims lights at specified times of the day.
These scheduled lighting events can apply to either all lights within a
building, or only to those in a specific
"zone" (for example, entrance, hallway, cafeteria, office, or even an
Scheduling not only saves energy and 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-based solutions make scheduling easy to set up, monitor and
Our intuitive Web-based software walks the user through creating and
modifying scheduled events, which can be applied
to either a single day or to multiple days (for example, specify the
same event for each week day), and also to a single
zone or to multiple zones.
Scheduled events can also contain conditions, which enable other
energy saving measures such as occupancy control and
daylight harvesting to be incorporated into the lighting schedule.
Monitoring tools show at a glance the current lighting levels for
each zone within the system. Users can also
temporarily over-ride conditions (illumination levels) for specific
zones, or even individual fixtures, to accommodate
