The project is 230 sq. ft including two toilet rooms, two lavatory rooms and an outdoor covered bar (including a refrigerator, waste and recycling recptacles and seating). The building will be used by approximately 80 to 100 people per day fluctuating during the summer and winter seasons. The question is: may this project obtain this prerequiste and will it qualify in general to obtain LEED certification assuming it met the required points? Specifically, public toilets are referenced within ASHRAE 62 in Table 6-4, Minimum Exhaust Rates. Additionally, bathrooms are included in the scope of this Standard per 2.1. Furthermore, the building meets the natural ventilation requirements along with the state energy code. In summary, I am not able to find any information within the reference guide preventing this project from obtaining LEED NC certification. It is a commercial permitted project per the Authority Having Jurisdiction. On page 14, Section III, paragraph A of the reference guide, it clearly does not prohibit certification of a restroom facility. Currently the project is anticipating at least Certified with Silver potential, therby proving LEED NC applicability. Thank you for your thoughtful consideration.
The CIR is inquiring as to whether a restroom facility may qualify for EQp1 and thus be eligible for LEED certification. The applicant is correct in their mention of the Reference Guide - all commercial buildings are eligible for LEED-NC certification. In order to show compliance for EQp1, the project must demonstrate that it meets the requirements of ASHRAE 62.1-2004, Sections 4 through 7 or equivalent. For this project, this verification will include documentation showing that it meets the exhaust air requirements of the standard as well as providing either the Ventilation Rate Procedure for any applicable mechanically ventilated spaces or documentation demonstrating compliance with paragraph 5.1 for naturally ventilated spaces.
