99. Million Solar Roofs is a DOE initiative to facilitate the installation of solar energy systems on one million
U.S. buildings by 2010. The initiative does not provide funding to design, purchase, or install solar energy systems.
Instead, the Million Solar Roofs Initiative brings together the capabilities of the federal government with key national
businesses and organizations and focuses them on building a strong market for solar energy applications on buildings
(http://millionsolarroofs.org/about_initiative/, February 4, 2005).

106. Commissioning is a quality assurance process that ensures that HVAC, controls, and electrical systems
operate efficiently in a new building. Recommissioning involves revisiting these systems at regular intervals to check and
retest them to ensure that they continue to operate efficiently. (For more information see: ENERGY STAR
Manual, http://www.energystar.gov/index.cfm?c=business.bus_upgrade_manual, April 12, 2005).

quality light (such as is now provided by incandescent or halogen fixtures at efficiencies ranging from 13 to 20 lm/W)
and 95 to 183 lm/W for medium quality light (such as now provided by many fluorescent fixtures at efficiencies in the
range of 70 to 80 lm/W) (Source: Hadley et al., 2004, op cit.). Carbon equivalent based on value of 19.29 MMTC per
