HI, We are going at this LEED process ourselves here at Tufts Health Plan and I have a minor question regarding LEED baseline for shower heads. My question: We have about 1700 employees here and only about 350 employees use the gym/shower each day. When doing the baseline calculation for LEED, Do we use 100% of the employees in the calculation or do we use only the 350? When doing the calculation using the Delta's Green Project Estimator, They did 100% of the employees for both U.S. Average and LEED in the calculation. Thank you for your help.

Hi Bruce - the standard assumption is that 10% of FTEs will go ahead and get showered any given day in buildings with showers. When filling out the submittal form, this percentage is applied on the backend, so you should enter the total FTEs. The form will automatically apply the 10% assumption - for example, if you enter 100 FTEs into the initial table in the form, the table for flow fixtures will then show 10 daily uses for showers. At present, it doesn't appear that the form accommodates a custom value for the number of showers per day, though if you could justify a certain value that differs from the standard 10% usage rate you may be able to make a case.
