Three Different Kitchen Sinks

It wouldn't be appropriate to assume that every FTE uses all three sinks in one day. You probably have 2 options to move forward: 1) Least Work --- include only the kitchen sink with the highest flow rate in your calculations. This will hurt your overall water reduction savings as you will be conserving the least amount of water for each use, but is the most conservative estimate. Any changes to break out the uses between the various fixtures would only help your overall reduction, so it would probably be awarded. If using this option, I would include a note in the Special Circumstances box of the form saying that you're electing to only include the highest flow rate for ease of calculations and that any inclusion of the other fixtures would only help, not hurt, your claimed overall reductions. 2) Most Realistic --- include all three kitchen sinks in the calculations. To do this, you would need to take the overall Total Daily Uses for that fixture and divide it amongst the three different sinks. You would need to develop some reasonable methodology for dividing the overall Total Daily Uses that works for your particular project. For example, if you had 100 FTE, you'd have a total of 100 Daily Uses to be split between all of the three collective kitchen sinks. If one sink is in the main break room, one is at a small coffee station near reception, and one is near the meeting rooms, it might be reasonable to assume that the majority of occupants will use the main break room (50?), followed by the coffee station sink (30?), and then the meeting room sink (remaining 20?). That's just a very rough example w/o of your project details. You definitely would need to form your own breakdown based on how your project operates/is setup. For this option, you'd just need to come up with a logical method for your particular project to breakdown the uses. It could be evenly split - it all depends on the nature of your project/how you think they'll be used. You definitely need to include a supplemental narrative to explain how you got to that breakdown for the reviewers. When you are inputting the data into the WEp1 Form, you will need to uncheck the "Default" box next to each of the kitchen sink fixtures. That makes the Total Daily Uses column editable for the fixture so that you can input your own number for that particular fixture. In breaking out the uses between the same fixture, just make sure that that total for all of those collective kitchen sinks adds up to the LEED default for the overall Total Daily Uses for that fixture (in the example above, you want the total to equal 100 as you have 100 FTE x 1 kitchen sink use/day). Option 2 really isn't that difficult for kitchen sink fixtures once you understand how to easily put it into the WEp1 Form. It will definitely get you the most accurate overall reduction as you'll be getting the extra water savings from those lower-flow sinks. Hope that helps!
