implement during the construction of the building than later during its operation. They
are also shown in Table 5.0.2. There are many prerequisites or credits which might have
variations applicable to the design or implementation of the project related to regional
conditions in the United States. All the prerequisites and credits for which regional
variations might be applicable are noted in the LEED 2009 Reference Guide and are so
listed in Table 5.0.1 for the Material and Resources category.
There are EP points under the Innovation and Design category available for exceeding
each of the respective credit criteria to a minimum level for some of the credits. All the
credit subcategories other than Building Reuse (MRc1.1 and 1.2) have an EP point
available. The available EP points for both versions 2.2 and 2009 are listed in Table 5.0.1.
Note that only a maximum total of four EP points are available in total for a project in
LEED 2.2 and a maximum of three in LEED 2009 and they may be from any of the noted
EP options in any of the SS, WE, EA, MR, or IEQ LEED categories (see Chap. 7).
One of the variables that must be determined for each project and that must be kept
consistent throughout the credits in a LEED submittal is the size and location of the
project site. The location of the site boundary is particularly important to the construction
