For our current project, virtually 100% of landscaping is turfgrass using 62.5% efficient rotors, usually a difficult combination for achieving 50% reduction. We have a unique situation where, if allowed, we present the existing system/techniques as our ‘Baseline Case’ and compare that to the proposed automated system 'Design Case' which is much more efficient. This would require convincing USGBC to consider these “Special Conditions” (the wasteful existing conditions vs the better proposed system) as a credible variation/approach in assessing water-efficiency. Has anyone had success trying to achieve this credit using this type of method or have suggestions for strengthening our case?
