General:
1 Ra was determined This value assumes as being the larger of the area method and the default per person
method. The occupant density used in the per person method was assumed to be one half of the maximum
occupant load assumed for egress purposes in the CBC. non-fixed seating and uses the occupant density
assumption in accordance with Section 120.1(c)3.
2 If this column specifies a minimum cfm/ft2 then it shall be used to comply with Section 120.1(d)4E.
Specific Notes:
A – For high-school and college libraries, the values shown for “Public Assembly Spaces – Libraries” shall be
used. B – Rate may not be sufficient where stored materials include those having potentially harmful
emissions.
C – Rate does not allow for humidity control. “Deck area” refers to the area surrounding the pool that is
capable of being wetted during pool use or when the pool is occupied. Deck area that is not expected to
be wetted shall be designated as an occupancy category.
D – Rate does not include special exhaust for stage effects such as dry ice vapors and smoke.
E – Where combustion equipment is intended to be used on the playing surface or in the space, additional
dilution ventilation, source control, or both shall be provided.
F – Ventilation air for this occupancy category shall be permitted to be reduced to zero when the space is in
occupied-standby mode
Typically a CO2 sensor

C – Exhaust shall not be required where two or more sides comprise walls that are at least 50% open to the outside.
D – Rate is per water closet, urinal, or both. Provide the higher rate where periods of heavy use are expected to occur. The lower rate shall be permitted to be used otherwise.
E – Rate is for a toilet room intended to be occupied by one person at a time. For continuous systems operation during hours of use, the lower rate shall be permitted to be used. Otherwise the higher rate shall be used.
F – See other applicable standards for exhaust rate.
G –For continuous system operation, the lower rate shall be permitted to be used. Otherwise the higher rate shall be used.

Controls §130.1
For general lighting, the manual area control shall permit the level
or amount of light provided while the lighting is on to be set or
adjusted by the controls specified in Section 130.1(b), (c), (d) & (e).
The manual area control shall permit the shutoff control to turn the
lighting down or off.
The multi-level lighting control shall permit the automatic daylighting control
to adjust the electric lighting level in response to changes in the amount of
daylight in the daylit zone.
The multi-level lighting control shall permit the demand responsive control to
adjust the lighting during a demand response event and to return it to the
level set by the multilevel control after the event.
The shutoff control shall permit the manual area control to turn the lighting
on. If the on request occurs while an automatic time switch control would turn
the lighting off, then the on request shall be treated as an override request.
The automatic daylighting control shall permit the multi-level lighting control
to adjust the level of lighting.
For lighting controlled by multi-level lighting controls and by occupant
sensing controls that provide an automatic-on function, the controls shall
provide a partial-on function that is capable of automatically activating
between 50-70 percent of controlled lighting power.
