Our project occupies (4) out of (10) floors of a building which was LEED 2.0 certified. We are attempting Silver under LEED CI 2009. If we are only counting fixtures in our scope of work, we have 38% reduction from the baseline, however, combining the core bathrooms gives us only 11%. The water use reduction baseline for the 2009 version is more stringent than the earlier version. Because the core bathroom fixtures were installed to meet the LEED 2.0 requirements, can we calculate them separately using the base line from the 2.0 version, so that we can receive the much-needed points we had designed for? Have you seen this circumstance before? Please let us know if there is a way to grandfather in these base building fixtures. Thanks
