There are a number of credit inquiries that relate to the shower requirements at college or university campuses, and as a result, the USGBC has expanded the proximity of changing/shower facilities to the project site from being required on the project site, to being required within 100 yards of the building, to the current standard of being required within 200 yards of the building. This credit inquiry seeks to have Sustainable Sites Credit 4.2 awarded by demonstrating that the intent of the credit is being fully achieved even if the specific distance limit is not. Our project is the renovation of the S.T. Dana Building Renovation, home of the School of Natural Resources & Environment at the University of Michigan, Ann Arbor. Dana is located in the central campus area facing onto the University's main quadrangle, know as the Diag. This area of the campus is served by a very large recreational and athletic facility, The Central Campus Recreational Building (CCRB). As an athletic facility, the CCRB provides a substantial number of locker rooms and showers for use by faculty, staff and students on the Central Campus. The CCRB is located roughly 300 yards from the Dana Building. It is easily within a 5 minute walk or a quarter mile of the building, which is the maximum distance LEED allows for walking to a building from public transit. This arrangement currently serves the biking population at the Dana Building with success as demonstrated by the transit survey conducted during the LEED project implementation. A transit survey conducted in April 2002 determined that the current biking population of the Dana Building exceeds the minimum of 5% required for this credit by 22%. - Number of respondents: 171 or 41% of the peak occupant load. (21 faculty; 39 staff; 111 students) - Number of respondents who bike from home to campus: 47 or 27%. Without showers in the building, this exceeds the LEED target by 22%. - Number of respondents who use their bikes to travel around campus during the day: 32. - The survey asked "if you had access to showers, would you be more likely to commute to school/work by bicycle or foot?" 124 or 72% said No. The transit study further determined that the average commute to campus is 6.1 miles and the average commute during the day around campus is 1.2 miles. The peak load occurs during the academic school year, September through May. The climate of Ann Arbor, Michigan, is such that showering after relatively short bike commutes is not necessary, like it might be in a southern and hot, humid campus. The minimum required number of bicycle racks is met within the LEED project boundary; numerous additional racks are provided within 200 yards of the building. The transit survey clearly demonstrates that the intent of this credit has been met at the Dana Building, even though the specific distance requirements are not met. Would this credit be awarded on these grounds? We also request confirmation that our peak occupant load and non-transient occupant load calculations are appropriate. They are as follows. 53 Staff (8 hr/day) = 53 Non-Transients and 53 FTE Occupants (peak load) 57 Faculty (8 hr/day) = 57 Non-Transients and 57 FTE Occupants (peak load) 81 PhD Students (6 hr/day) = 0 Non-Transients and 61 FTE Occupants (peak load) 185 Master (Except LA) Students (4 hr/day) = 0 Non-Transients and 93 FTE Occupants (peak load) 235 Undergraduate Students (2 hr/day) = 0 Non-Transients and 59 FTE Occupants (peak load) 60 Master of Landscape Architecture Students (8 hr/day) = 60 Non-Transients and 60 FTE Occupants (peak load) 29 LS&A (4th Floor) (8 hr/day)= 29 Non-Transients and 29 FTE Occupants (peak load) 700 Total = 199 Non-Transients and 411 FTE Occupants (peak load) Based on 411 FTE Occupants (peak load), secure slots are needed for 21 bicycles (5% min). Based on 199 Non-Transients, two showers are needed.
The transit survey provides clear evidence that there is a sizable bicycling community at the campus, and sufficient bicycle racks have been provided for these cyclists. However, based on the credit requirements and previous CIRs on this issue, the showers that are located 300 yards from the project unfortunately cannot be used to capture this point. Your calculation methodology used to determine the number of FTE building occupants and non-transient occupants is acceptable and consistent with guidelines provided by previous CIRs for this, including the ruling dated 8/7/2002. Applicable Internationally.
