*Based on LEED registered projects listed in the USGBC web site, accessed May 30, 2007. These
totals are lower than those in the “LEED Metrics” list.
† LEED-CS v. 2.0 became effective in the spring of 2006, so it is only about 2 years old, not enough
time for most large projects to finish construction and certification.

have a strong incentive to proceed all the way from registration to certification.
However, in examining the “percentage completion” rate in Table 5.3, we see it’s no
greater than for the other LEED systems.

LEED FOR COMMERCIAL INTERIORS
LEED-CI represents a wholly different situation, with an average size of only 50,000
square feet (one or two floors of an office building) and a quick project turnaround
time. Most remodeling and tenant improvement projects happen quite fast, so that a
decision to pursue LEED-CI must be made at or near the outset of a project. In that
case, one expects the client and the design team to be committed to the end results.
However, a countervailing factor is that the average project cost is less than $5 million,
often less than $2 million, so that the fixed cost of completing a LEED-CI project
(perhaps $50,000 to $100,000) is a more significant factor in the overall project budget.
As a result, the percentage of registered projects already completed under LEED-CI ver-
sion 2.0 (in place since November of 2004) is less than that of LEED for New
Construction. As an example, Exelon Corporation, a major electric utility, used
LEED-CI to fit out its new headquarters office space (Fig. 5.1).
