NOTES:
1. The ducted supply air shall not be used to ventilate the janitor
closets and private toilets with one fixture. Instead, room air
from the occupied spaces and corridors, directly connected to the
janitor closets and private toilets, shall be used as make up air
for exhaust. The make up air shall be brought in by door undercuts
and louvers. The capacity of the undercuts shall be limited to 150
CFM.
2. For kitchen, establish the supply air quantity to meet the cooling
load and/or equipment exhaust requirements.
3. The ducted supply air shall be used to ventilate the public
toilets equipped with multiple fixtures. The public toilets shall
be treated as a dedicated temperature control zone. To maintain
15% negative pressure in public toilets, room air from the
corridors shall be transferred as make up by door louvers and/or
undercuts.
4. The locker room shall receive ducted supply air and shall be
treated as a dedicated temperature control unit. All air supplied
to the locker rooms (and make up air transferred from the
corridors to maintain negative pressure) shall be exhausted
outdoors through the toilets/showers adjoining the locker room.
5. The soiled storage spaces shall receive ducted supply air and
shall be maintained under negative pressure (15%) by drawing room
air through the door undercut.
