TABLE 2.8.1 Lighting Power Densities
include solar power lighting or other lighting that does not use electricity or fossil
fuels, and this does not apply to equipment or portions of building systems that use
energy primarily for industrial, manufacturing, or commercial processes. Or at least,
this is what the author has interpreted from the LEED-NC 2.2 and 2009 Reference
Guides.
