The approximate classifications used in LEED-NC 2.2 for steps 2 through 4 are
summarized in Table 5.0.4. These will also be further explained under each individual
subcategory.
The last summary detail in the credit calculations for this category is to understand
which items can be included in multiple credits and which cannot. This is summarized
in Table 5.0.5. Note that some individual items may be made of several types of materials.
Values and allocations for these are usually by weight percent of the item.
