technologies available today can help meet these lighting needs
while providing good quality lighting that minimizes light
pollution, conserves energy, and enhances community ambience,

consumption of major building types in California, with electricity
representing over 80% of this, and with energy-intensive
refrigeration consuming the greatest fraction of electricity.

or it may be old and
inefficient. Either way, the electricity used in the building
will likely be produced with inherent inefficiencies. The
efficiency of fossil fuel based electricity production averages 34%
(although new combined cycle plants can exceed 50% efficiency). The
ultimate efficiency of any building pulling electricity from the
grid is limited by that number.

is one of the largest energy-consuming end uses of a commercial
food service facility. In a typical restaurant, the HVAC (heating,
ventilation and air conditioning) system represents 20 to 30
percent of total energy consumption. The kitchen ventilation system
can account for up to 50 percent of that HVAC load.
