Fig. 1 is a bar graph of the source EUI of these 21 LEED office
buildings with bar width chosen to represent the floor area for
each building as a percentage of the total area contained in the 21
buildings and color chosen to represent the level of LEED certification
– Gold (yellow), Silver (gray), and Certified (green). The area of
each rectangle represents the annual source energy (not intensity)
associated with each building.
