Our project is a remodel of the 2nd floor of a 3 story office building (CI v4). If our LEED project boundary is just the square feet of the 2nd floor (14,648 sf), and no new parking is being added for the entire building can any credit be earned for reduced parking?

I also don't understand what to do with the ratios listed in the ITE tables.

Do we look at the ratio for just the square feet of the second floor and multiply (3.8 / 1000 sf) X 14648 = 55.6624, which gives 55 spaces for a baseline, then calculate (55 - 200 total parking capacity) / 55 x 100 = -263.63? This does not make any sense.

Or do we use the square feet for the total building (60,541 sf) and use the formula 3.8 x (0.4 x (60541/75000) = 5 spaces for a baseline, then (5 - 200) / 5 x 100 is still a negative number?

This has got to be the most confusing credit calculation I've ever seen, especially since it does not explain how to adapt it to a CI project with only one floor of a building being remodeled. Or should this credit be listed as unavailable for CI projects?

Worst credit documentation ever!
