LEED only cites only two types of irrigation and their efficiency. For quite some time now the irrigation manufacturing industry has improved their sprinkler products tremendously and it might be fair to say that the efficiency for some sprinklers, e.g. Hunter MP Rotator nozzles, is by far higher than 0.625. Cities sometimes require above ground irrigation which limits the opportunities to receive LEED WEc1. Does anyone have suggestions how to incorporate a higher efficiency number in the LEED calcs? Advice is greatly appreciated. Thanks,
