Buoyancy and expansion caused by the design fire in accordance with paragraph (I)(9)(909.9) of this rule shall be analyzed. The system shall be designed such that these effects do not adversely interfere with the system’s capabilities.
The design shall consider the adverse effects of wind. Such consideration shall be consistent with the wind-loading provisions of the building code as listed in rule 1301:7-7-47 of the Administrative Code.
The design shall consider the effects of the heating, ventilating and air-conditioning (“HVAC”) systems on both smoke and fire transport. The analysis shall include all permutations of systems status. The design shall consider the effects of the fire on the heating, ventilating and air-conditioning systems.
The design shall consider the effects of low temperatures on systems, property and occupants. Air inlets and exhausts shall be located so as to prevent snow or ice blockage.
All portions of active or passive smoke control systems shall be capable of continued operation after detection of the fire event for a period of not less than either 20 minutes or 1.5 times the calculated egress time, whichever is less.

Smoke barriers shall comply with the building code as listed in rule 1301:7-7-47 of the Administrative Code. Smoke barriers shall be constructed and sealed to limit leakage areas exclusive of protected openings. The maximum allowable leakage area shall be the aggregate area calculated using the following leakage area ratios:

1. Walls: A/Aw = 0.00100

2. Exit enclosures: A/Aw = 0.00035

3. All other shafts: A/Aw = 0.00150

4. Floors and roofs: A/AF = 0.00050

where:
A=Total leakage area, square feet (m2).
AF =Unit floor or roof area of barrier, square feet (m2).
Aw=Unit wall area of barrier, square feet (m2).

The leakage area ratios shown do not include openings due to doors, operable windows or similar gaps. These shall be included in calculating the total leakage area.

Total leakage area of the barrier is the product of the smoke barrier gross area multiplied by the allowable leakage area ratio, plus the area of other openings such as gaps and operable windows. Compliance shall be determined by achieving the minimum air pressure difference across the barrier with the system in the smoke control mode for mechanical smoke control systems. Passive smoke control systems tested using other approved means, such as door fan testing, shall be as approved by the fire code official pursuant to paragraph (A)(1)(901.1) of this rule. At locations or in structures not regulated by the building code as listed in rule 1301:7-7-47 of the Administrative Code, the test method shall be approved by the fire code official prior to system installation.

Openings in smoke barriers shall be protected by automatic-closing devices actuated by the required controls for the mechanical smoke control system.

Ducts and air transfer openings are required to be protected with a minimum Class II, 250°F (121°C) smoke damper complying with section 716 of the building code as listed in rule 1301:7-7-47 of the Administrative Code.
The primary mechanical means of controlling smoke shall be by pressure differences across smoke barriers. Maintenance of a tenable environment is not required in the smoke-control zone of fire origin.

The minimum pressure difference across a smoke barrier shall be 0.05-inch water gage (0.0124 kPa) in fully sprinklered buildings.

In buildings permitted to be other than fully sprinklered, the smoke control system shall be designed to achieve pressure differences at least two times the maximum calculated pressure difference produced by the design fire.

The maximum air pressure difference across a smoke barrier shall be determined by required door-opening or closing forces. The actual force required to open exit doors when the system is in the smoke control mode shall be in accordance with paragraph (H)(1)(c)(1008.1.3) of rule 1301:7-7-10 of the Administrative Code. Opening and closing forces for other doors shall be determined by standard engineering methods for the resolution of forces and reactions. The calculated force to set a side-hinged, swinging door in motion shall be determined by:

F = Fdc + K(WAΔP)/2(W d)(Equation 9-1)
where:
A=Door area, square feet (m2).
d=Distance from door handle to latch edge of door, feet (m).
F=Total door opening force, pounds (N).
Fdc=Force required to overcome closing device, pounds (N).
K=Coefficient 5.2 (1.0).
W=Door width, feet (m).
ΔP=Design pressure difference, inches of water (Pa).
When approved by the fire code official pursuant to paragraph (A)(1)(901.1) of this rule, smoke migration through openings fixed in a permanently open position, which are located between smoke-control zones by the use of the airflow method, shall be permitted. The design airflow shall be in accordance with this paragraph. Airflow shall be directed to limit smoke migration from the fire zone. The geometry of openings shall be considered to prevent flow reversal from turbulent effects. At locations or in structures not regulated by the building code as listed in rule 1301:7-7-47 of the Administrative Code, airflow design method shall be approved by the fire code official prior to system installation.

The minimum average velocity through a fixed opening shall not be less than:

F = Fdc + K(WAΔP)/2(W d)(Equation 9-1)
where:
A=Door area, square feet (m2).
d=Distance from door handle to latch edge of door, feet (m).
F=Total door opening force, pounds (N).
Fdc=Force required to overcome closing device, pounds (N).
K=Coefficient 5.2 (1.0).
W=Door width, feet (m).
ΔP=Design pressure difference, inches of water (Pa).
This method shall not be employed where either the quantity of air or the velocity of the airflow will adversely affect other portions of the smoke control system, unduly intensify the fire, disrupt plume dynamics or interfere with exiting. In no case shall airflow toward the fire exceed 200 feet per minute (1.02 m/s). Where the formula in paragraph (I)(7)(a)(909.7.1) of this rule requires airflows to exceed this limit, the airflow method shall not be used.
When approved by the fire code official pursuant to paragraph (A)(1)(901.1) of this rule, mechanical smoke control for large enclosed volumes, such as in atriums or malls, shall be permitted to utilize the exhaust method. Smoke control systems using the exhaust method shall be designed in accordance with NFPA 92B as listed in rule 1301:7-7-47 of the Administrative Code. At locations or in structures not regulated by the building code as listed in rule 1301:7-7-47 of the Administrative Code, the exhaust method shall be approved by the fire code official prior to system installation.
The height of the lowest horizontal surface of the smoke layer interface shall be maintained at least 6 feet (1829 mm) above any walking surface that forms a portion of a required egress system within the smoke zone.
The design fire shall be based on a rational analysis performed by the registered design professional and approved by the fire code official pursuant to paragraph (A)(1)(901.1) of this rule. The design fire shall be based on the analysis in accordance with paragraph (I)(4)(909.4) of this rule and this paragraph. At locations or in structures not regulated by the building code as listed in rule 1301:7-7-47 of the Administrative Code, the design fire shall be approved by the fire code official prior to system installation.
The engineering analysis shall include the characteristics of the fuel, fuel load, effects included by the fire, and whether the fire is likely to be steady or unsteady.
Determination of the design fire shall include consideration of the type of fuel, fuel spacing and configuration.
The analysis shall make use of best available data from approved sources and shall not be based on excessively stringent limitations of combustible material.
A documented engineering analysis shall be provided for conditions that assume fire growth is halted at the time of sprinkler activation.
Equipment including, but not limited to, fans, ducts, automatic dampers and balance dampers shall be suitable for their intended use, suitable for the probable exposure temperatures that the rational analysis indicates, and as approved by the fire code official pursuant to paragraph (A)(1)(901.1) of this rule. At locations or in structures not regulated by the building code as listed in rule 1301:7-7-47 of the Administrative Code, the equipment shall be approved by the fire code official prior to system installation.

Components of exhaust fans shall be rated and certified by the manufacturer for the probable temperature rise to which the components will be exposed. This temperature rise shall be computed by:

Ts = (Qc/mc) + (Ta)(Equation 9-3)
where:
c=Specific heat of smoke at smokelayer temperature, Btu/lb°F • (kJ/kg • K).
m=Exhaust rate, pounds per second (kg/s).
Qc=Convective heat output of fire, Btu/s (kW).
Ta=Ambient temperature, °F (K).
