We are busy assessing whether or not the "Public lavatories have outlet temperature controls that limit the discharge temperature to 110°F" ASHRAE 90.1 Mandatory requirement. ASHRAE 90.1 defines 'public restrooms' as 'used by the transient public'. If we have an office building with access control to get into the office, and then open plan office space with common restrooms for staff and guests who are signed in, would that be defined as public? Some transient visitors will use it but predominantly it will be by permanent staff.
