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.
