Toilets: private or public?

Hi Francesco - did you receive any response to this? We also have an office building. There is only on toilet per bathroom, but the bathroom is availble for all occupants using the office. Would this be considered a private bathroom?

Hi! Private in this case means: residential (or hotel/motel) From the LEED Reference Guide: Public versus Private Lavatories
Lavatory faucets must be classified as public or private. The Uniform Plumbing Code, International Plumbing Code,
and the National Standard Plumbing Code each define private as those fixtures in residences, hotel or motel guest
rooms, and private rooms in hospitals. All other applications are deemed to be public.
Fixtures used by residential occupants and fixtures used by residential-type occupants who use the building for
sleeping accommodations fall into the private classification. Resident bathrooms in dormitories, patient bathrooms
in hospital and nursing homes, and prisoner bathrooms are considered private use.
If it is unclear whether the classification should be public or private, default to public use flow rates in performing the
calculations.

Thank for the quick reply. I see in my question that it is not clear that I am looking for which air flow rates to use in the bathrooms according to ASHRAE 62.1. As written, then it is a office building, with seperate bathrooms, which can be used by multiple occupants. Can we for this reason look at it as a private bathroom, as there is only one person at a time using it?  

Hi Lise, By re-reading the notes under table 6-4, it seems that ASHRAE and LEED have different definitions for private and public. On 62.1, private bathrooms are bathrooms that are used by a single person at a time. If your building is served by bathrooms for single users, those are private bathrooms. For continuous operation you use the lower number and for intermittent operation you use the higher number.
