ABSTRACT:
Francis
Rubinstein of Berkeley Lab and Peter Pettler of Vistron, Corp.have
made it possible to reliably send control signals from an
electrical junction box to fluorescent and high intensity
discharge (HID) lamps over existing wiring. The Phase Cut
Carrier (PCC) system works without compromising the performance
of the electrical wiring distribution system and has several
advantages over Power Line Carrier (PLC), the conventional
technique used to communicate with building loads over in-place
wiring.
The
Berkeley Lab dimmable lighting control system not only provides
increased lighting comfort and control to users, but allows
building managers to reduce operating costs by implementing
advanced lighting control strategies, such as daylighting
and demand response control. Daylighting uses photosensors
to measure daylight and automatically raises or lowers electric
light levels in response. This results in significant cost
savings since the daylighting potential is greatest when electricity
prices are highest. Demand response control allows building
managers to reduce lighting in entire facilities during periods
when they have been notified that electricity shortages are
likely or imminent. Energy regulators in states that have
an insufficient electrical capacity are re-structuring electricity
billing to encourage the use of demand response control beyond
the current rate schedule. |
