tenant LEED office building in Georgia. However, this benefit of enhanced reputation
is too abstract to calculate with any degree of confidence. Moreover, since the overall
intent of this book is to make the business case for green buildings generally, the intan-
gible benefit we might see by delivering a first-to-the-state product is not replicable as
more LEED for Existing Buildings projects are developed. As such, we don’t include
it in our cost/benefit analysis here.
The same logic applies to the longer-term intangible benefits that occur as a result
of reducing our overall liability and risk. With conservation measures in place, are we
less prone to be cited for violating outdoor water use regulations? Yes. Can we place
a value on that reduced exposure? Probably not.
With these various costs and benefits of delivering a LEED for Existing Buildings proj-
ect in mind, we can now look at a basic discounted cash flow analysis for Crestwood.
As can be seen in Figure 6.4, total costs of the LEED program amounted to $163,000
($137,000 initially plus the on-going cost of the recycling program of $26,000). Total
benefits are conservatively estimated at $450,000 (with a primary contributor being our
over-market occupancy). The net present value (NPV) of the LEED investment comes to
$135,000, with an internal rate of return on our green investment of 42.3 percent.
