158 INTEGRATED PROJECT MANAGEMENT—COST/BENEFIT ANALYSIS OF GREEN BUILDINGS

so that many of the LEED credits, which represent “best practices,” are not excluded
from consideration. These analyses help design teams evaluate alternatives that are in
the LEED system but which may not be part of traditional design decisions. Because
of risk mitigation and lowered maintenance costs, the advanced indoor air quality plan
pays off in less than 2 years.

INDOOR ENVIRONMENTAL QUALITY:
CREDIT 8.2—DAYLIGHT AND VIEWS
Let’s look finally at two alternatives for daylighting and view creation (Table 8.9). In
this case, the two alternatives, installing interior and exterior light shelves, as against
providing north-facing skylights and reconfiguring the floor plate, have similar benefits
(Fig. 8.8). Knowing this, we can turn to other design considerations because either
solution will yield positive net benefits over the 10-year period of analysis.

SUMMARY OF THE EVA BENEFITS

During our review of all of the credit examples discussed above, we should always
review how they impact our Triple Bottom Line EVA Log, as shown in Table 8.10. Not
surprisingly, each of these measures creates strong triple-bottom-line benefits for each
project. Creating high-performance projects is always going to be a balancing act
between these benefits and their net costs.

ANALYSIS OF A COMPLETE PROJECT
When the team analyzes credits or solutions, there are many synergies that should be
reviewed. Many credits and solutions on LEED projects are directly related to other
elements within the project. These opportunities provide the team to really accelerate
the benefit curves for projects and reduce the life-cycle paybacks of many items.
