Besides the fact that I find this template absolutely confussing I'm totally thrown by the Flow Rate chart. Under lavatories it compares what you've got against the baseline of 0.5 gpm/gpc against what you have. We retrofit our faucets to 1.0 gpm and the template seems quite unhappy. A red lettered sentence pops up telling me that the -17% we received is atypical. I'm sure that most building's with older faucets are not metered. If I have a 1.0 gpm faucet but it only runs for 30 seconds I meet the baseline but the template doesn't account for that. What is everyone doing? Thanks!

Sharron, you're in good company - the WEp1 credit form is one of the more frustating aspects of LEED-Online v3 for many of us. First of all, don't worry too much about that "red-lettered pop-up" alert. Complete the Credit Form using accurate information for your building fixtures and see what it calculates as your potable water reduction amount. The LEED baseline is determined automatically by the Credit Form (based on 2006 UPC/IPC codes), but you don't necessarily need to match every one of these code flush/flow rates in order to meet WEp1. Buildings that use low-flow fixtures that meet or exceed the codes will most likely be eligible to earn additional points under WEc2; but it's not a requirement that you actually mirror the codes. Complete the Credit Form, see how well your building is doing and make sure to provide manufacturer documentation as part of your submittal for any fixtures that are higher or lower than the UPC/IPC codes.
