NOTES: (1) Data was based on the most reliable information available at the time of analysis,
and is subject to change should additional information become available. (2) Lighting Power
Density is Watts per Square Foot. (3) The target LPD value shown here is taken from
ANSI/ASHRAE/IESNA Standard 90.1-2004. Per the Energy Policy Act of 2005, a new Federal
rule is due out from DOE in August 2006 requiring further energy savings of 30%, if cost
effective. Impacts on individual LPD's cannot be anticipated at this time.
