The LEED-NC 2.2 and 2009 Reference Guides provide tables that summarize some of
these prerequisite and credit characteristic, including the main phase of the project for
submittal document preparation (Design or Construction).
Even though the entire LEED process encompasses all phases of a project, the
prerequisites or credits that are noted as Construction Submittal credits usually have
major actions going on through the construction phase that, unless documented through
that time, may not be able to be verified from preconstruction documents or the built
project. Sometimes these credits have activities associated with them that cannot or
need not be performed until the beginning of, or subsequent to, the construction phase.
EAp1, EAc3, EAc5, and EAc6 have been noted in the construction submittal column in
Table 4.0.1.
Three of the credit subcategories listed in Table 4.0.1 have the icon EB noted after
their title (EAc1, EAc3, and EAc5). This icon is a tool to help those who wish to proceed
with the continuing LEED-EB certification (Existing Building) after certification of LEED-
NC (New Construction or Major Renovation) is obtained. Those credits noted with this
icon are usually significantly more cost-effective to implement during the construction
of the building than later during its operation. They are also shown in Table 4.0.1. There
