Hello, we are working on an University project which has a directive on Gender Neutral toilets which means there are no urinals in the building. Though it is great that the University is promoting this but from a LEED standpoint this will take a major hit as there will be urinal uses which will be compensated with WC flush of 1.1gpf (LEED Baseline - 1gpf). With this, we are barely meeting the prerequisite. Has anyone ever encountered a project with similar scenario? Or any precedent that we can put forward to USGBC? I will love to know your thoughts on this. Thanks.

Hi Jude, are you using urinals in the baseline even though none are to be installed? You don't need to do that - the baseline and design fixtures and uses should match in everything but flush/flow rate. Just set the "percentage of males expected to use urinals" line to 0%, include a "water closet (male)" and "water closet (female)" in the calculator, and the form will calculate 3 WC uses for male occupants.

Here's one more, Emily. This University uses a battery operated progammable autoflush for urinals set to one flush per 24 hrs. It's a Sloan Royal 1.0 GPF flushometer with the add-on Ecoblue timer unit. If the manual handle that normally comes with the unit is not installed and flushing can only occur per timer, can I divide the total number of expected uses per day by 1.0gpf?

That one's new to me! I might just call it a waterless urinal since one gallon per day is negligible relative to all your other water use.

Just wanted to add an interesting design solution - we also have a University project including gender neutral restrooms and were faced with the increased water usage problem from lack of urinals. Aside from adjusting the LEED calculation, we also wanted to reduce overall water usage (especially because we are using harvested rainwater for flushing). Enter the solution: single occupant urinal closets. We are providing single occupant toilet rooms AND single occupant urinal rooms, so users can self select which option works best for them and still maintain gender neutrality. We ran this solution by the school's LGBTQ representatives and they felt like it was an appropriate solution to address both social equity AND water usage. Just wanted to share in case others are faced with the same challenge!
