We're looking to pursue this credit, but are a bit confused how the baseline is calculated for an interior renovation project with a portion of new construction. Our mechanical engineer seems to believe our baseline amount for WEc3 is actually taken from the existing water efficiency amounts instead of from the table of baseline amounts in the credit. Is anyone familiar with the baseline calculations and how this would work for a renovation?

MacKenzie, if you were doing LEED-EBOM certification, then improvement over a baseline might be more relevant. In a LEED-CI or LEED-NC project, the baseline is determined by the definitions provided in the credit language (see the tab above), not pre-existing conditions in the building.
