SECTION 921.0 SMOKE CONTROL SYSTEMS
| |
|
921.1 General: Smoke control systems required by
this code shall conform to the provisions of this section.
| |
|
921.2 Design Criteria: The smoke control system
shall be designed to keep the smoke layer interface above the highest
of either: the highest unprotected opening to adjoining spaces, or
six feet (1,829 mm) above the highest floor level of exit access open
to the atrium for a period of 20 minutes. This limiting height of
the smoke interface above the atrium floor is "z." Provisions shall
also be made to provide for smoke removal from the atrium at a rate
of not less than two air changes per hour by means of natural or mechanical
ventilation.
| |
|
921.2.1 Passive System: Active smoke control is
not required where it is shown that the smoke interface level requirement
will be met without operating smoke exhaust.
|
|
921.2.1.1 Regular Spaces: For spaces with flat
ceilings, a constant horizontal cross-section area above the smoke
layer interface, and an A/H2 ratio between 0.9 and 21, the following
equation shall be used to estimate the height of the interface at
20 minutes:
| ||||
|
Z = 0.67 H - 0.28H In
| ||||
|
Where:
| ||||
|
z
|
=
|
Height from floor to the smoke interface (feet)
| ||
|
t
|
=
|
Time for interface to descent to z; use 1,200 seconds
| ||
|
H
|
=
|
Atrium height; floor to flat ceiling (feet)
| ||
|
Q
|
=
|
Steady heat release rate; use 4,400 Btu/sec. where the primary
use groups is M, S-1, or F-1. Otherwise use 2,000 Btu/sec.
| ||
|
A
|
=
|
Horizontal cross-sectional are of the above ceiling space being
filled (square feet). Maximum A to be used shall be: A = 21 H2
| ||
|
921.2.1.2 Irregular Spaces: For spaces with sloped
or irregular ceilings, A/H2 ratios outside the specified range, or
varying cross sections, the filling time shall be determined using
numerical integration from the ceiling to the critical smoke interface.
The following equations shall be used to determine the rate of smoke
production:
| ||||
|
Where the interface level is above the limiting elevation (z)
use:
| ||||
|
V = 20.8Q 1/3 z 5/3 + 3.98 Q
| ||||
|
Where the interface level is below the limiting elevation (Z)
use:
| ||||
|
V = 19.7 Q 3/8 z
| ||||
|
Where:
| ||||
|
V
|
=
|
the volumetric rate of smoke production (cubic feet per minute)
| ||
|
z1
|
=
|
limiting elevation (feet) = 0.533 Q 2/3
| ||
|
921.2.2 Mechanical Systems: Where the smoke filling
predicted in Section 921.2.1 does not meet the design criteria of
Section 921.2, mechanical exhaust shall be provided to maintain these
conditions.
| ||||
|
Sufficient mechanical exhaust shall be provided to maintain
the smoke layer interface at or above the critical elevation for the
twenty-minute period. The volumetric rate of smoke production (v)
as determined by the equations in Section 921.2.1.2 shall be used
to determine the exhaust rate to maintain the interface at the critical
level (z). The minimum exhaust rate to be supplied for smoke control
shall be adjusted in accordance with Table 921.2.2.1.
