SMOKE CONTROL METHODOLOGY
The new Hyatt Regency Portland – Oregon Convention Center, will be a new high-rise hotel building
located in Portland, Oregon. The project site is bounded by NE Multnomah St. to the North, NRE Martin
Luther King Jr Blvd. to the East, NE 2nd Ave. to the West, and NE Holladay St. to the South. It is
understood that the building will be constructed to achieve LEED Silver status. The building is being
designed to the 2014 Oregon Structural Specialty Code (OSSC).
The 14 story building will include the following occupancies:
• Residential Group R-1 – Guest rooms.
• Assembly Group A-3 – Main Ballroom, Meeting Rooms, Junior Ballroom, Hospitality Suites,
Fitness Center, Lap Pool, Regency Club, and Pre-function spaces.
• Assembly Group A-2 – Restaurant and bar.
• Mercantile Group M – Market.
• Business Group B – Various offices.
• Storage Group S-1 (Moderate hazard storage) - Various storage locations
The Hyatt Regency Portland building will be considered a high-rise building as the highest occupied level
of the building will be more than 75 feet above the lowest level of fire department access. The building
will be required to comply with OSSC Section 403 High-Rise Buildings.
As a high-rise building, the Hyatt Regency is required to have all exit stairways serving floors more than
75 feet above the lowest level of fire department access be constructed as smokeproof enclosures per
OSSC 403.5.4. Smokeproof enclosures for the Hyatt Regency project will use the stair pressurization
alternative per OSSC 909.20.5.
The Hyatt Regency design team is proposing to also provide a performance based smoke control design
using the airflow method per OSSC 909.7. The airflow method will be used to omit smoke dampers from
guest room supply air ducts. The supply system consists of three Heat Recovery Units (HRU) located on
the roof that supply conditioned air to a horizontal distribution system located above the 14th floor ceiling.
The distribution ducts supply conditioned air to the 26 supply air shafts distributed throughout the floor.
The risers drop within 2-hour shafts and branch to each floor supply grille with a 6-inch round duct with
fire damper at the shaft wall penetration.
SMOKEPROOF ENCLOSURES
Tower Stair A, B, and C serve floors more than 75 feet above lowest level of fire department access and
will be required to be constructed as smokeproof enclosures. Podium Stair A and B only serve level 0 to
2. The Podium Stairs will not serve floors 75 ft. or more above the lowest level of fire department access
and will not be required to be constructed as smokeproof enclosures.
There will be two-story vertical openings in the lower levels of the building. The open stair and open
escalator between level 1 and level 2 will not be considered exit enclosures and do not serve floors above
75 ft. above the lowest level of fire department access. The escalator between level 0 and level 1 will
have a fire shutter, isolating level 0 from level 1, separating it from the open stair and escalator.
Tower Stair B extends to the roof/mechanical penthouse. Tower Stairs A and C extends to Level 14 and
is equipped with a roof hatch. The roof hatch is not part of the stairway pressurization system but is

required. The stairway roof hatches will be monitored for position as an open roof hatch may compromise
the pressurized stair (see smokeproof enclosures exhibit 1 for reference).
Exhibit 1 – Smokeproof Enclosures Schematic
The 2014 OSSC Section 909.20.5 states that the exit stairways shall be pressurized to a minimum
positive pressure of 0.10”w.g. and a maximum positive pressure of 0.35”w.g. with all stairway doors
closed. The maximum pressure shall be adjusted to limit the maximum door opening force to 15-pound
door latch force, with a 30 pound force to set the door in motion with a maximum 15 pounds to fully open
the door per OSSC, section 1008.1.3.
The pressure differential shall be measured relative to the corridor on all floors. For Stair B, the pressure
from the stair to the elevator vestibule serving the fire fighters service elevators will also be measured for
a 0.10” w.g. minimum difference.
The exit stairway shall be equipped with a single dampered relief opening at the top of the stair shaft.
CONTAM was used to model the pressurization fan systems, including the single relief. The City of
Portland Code Guide OSSC/10/#10(dated May 13, 2016) identifies three prescriptive options for provision
of pressurized stairs. In lieu of providing a prescriptive option for the pressurized stairs, a performance
based design using CONTAM has been conducted to size the stairwell pressurization systems. Results
show that the pressure requirements listed in 2014 OSSC, Section 909.20.5 are achieved with single
relief vents on all stairs and with single injection points on Stairs A and C, and two injection points on Stair
Hyatt Regency Portland Oregon Convention Center Smoke Control & Mechanical Design Narrative February 6, 2017 Page 3 of 17
B. The relief opening shall have two dampers in series, a counter balanced barometric (back draft
damper, and a motorized damper (spring open, power close, UL 555S smoke damper) meeting the
requirements of the Energy Code. The motorized damper will be monitored for position. The counter
balanced barometric (back draft) damper shall be set to open at 0.15” pressure at 3,000 CFM.
Stair A and C injection points will be supplied from the top of the stair shaft. Stair B is supplied from the
top of the stair shaft with the second injection point being provided via a ducted shaft down to level 7.
The “shaft” shall be part of the stairwell and shall not have a fire- resistance rating between the “shaft”
and stairwell.

NOTE - The airflow estimates are from the CONTAM model and represent the airflow for both winter and
summer conditions. The airflow estimates include 3,000 CFM of relief. The EOR shall design the relief
size such that 3,000 CFM relief can be achieved at 0.15” S.P. All fans shall have Variable Frequency
Drives. The fan shall be selected at the design CFM with the VFD at maximum 75% speed. The fan shall
be selected such that it will operate in the stable area of the fan curve at the minimum fan CFM listed
above and without replacing sheaves. The fan shall also be selected such that it will operate in the stable
area of the fan curve at the maximum fan CFM listed above. Replacing sheaves to achieve the maximum
fan CFM is acceptable, but the fan break horsepower shall not exceed the motor horsepower. Fan
motors shall be Class B. Fans shall have a minimum service factor of 1.15.
The required fan external static pressure shall be calculated by the mechanical EOR based on the airflow
and the duct and fitting losses. The vertical stairway shaft and the entrance loss into the stairway shall be
included in the stair pressurization calculation. The static pressure in the shaft shall be added to the duct
and fitting losses. Use 0.4”w.g. for the stairway pressurization fans as an allowance for shaft static.
AIRFLOW METHOD
The HVAC system for the Hyatt Regency has been designed to provide multiple smaller shafts which
serve two units from centralized rooftop units which branch out on the 14th floor. As currently designed,
the supply air openings would require fire and smoke combination dampers at each shaft penetration per
OSSC 717.5.3. Exhaust openings will use the exception of providing sub ducts with continuous exhaust
(including standby power) and will not need fire or smoke dampers. As an alternative to the fire and
smoke dampers for the supply shafts serving rooms, the use of the airflow method is proposed.
Fire/smoke dampers will be omitted from the supply shaft and will supply air to rooms at an airflow speed
at the shaft boundary to prevent smoke intrusion, and at a velocity of less than 200 ft. per minute at the
diffuser outlet to the room during a fire event (See Appendix Airflow Method calculations). The room
exhaust will also serve as part of the airflow method, pulling smoke out of the room while the supply
provides air to prevent smoke migration into the supply shaft.

RATIONAL ANALYSIS
The Hyatt Regency Portland is required to be provided with smokeproof enclosures and post fire smoke
cleanup capabilities as the building is a high-rise per OSSC Section 403. The design team is proposing
to use the airflow smoke control method to omit smoke dampers in some locations within the building,
which will be further described below. There are not currently any other building features which would
require additional smoke control system components.
OSSC, Section 909.4 requires that systems or methods of construction to be used for smoke control be
based on rational analysis in accordance with well-established principles of engineering. At a minimum,
the analysis should address stack effect, temperature effects of fire, wind effect, HVAC systems effect,
and climatic effects.
The rational analysis will be performed in part by using the Steady Airflow analysis computer model
CONTAM. The CONTAM software was developed by the National Institute of Standards and Technology
(NIST) and is a multi-zone indoor air quality and ventilation analysis computer program, used to evaluate
airflows and pressure differential within the building.
1. Stack Effect:
Stack effect was evaluated using the CONTAM model. The summer and winter temperatures
ambient temperatures were based on ASHRAE climate data for Extreme Summer and Winter
temperatures. 19.2 deg.F for winter conditions and 98.8 deg.F for summer conditions. An
intermediate temperature of 45 deg.F was assumed in the stairwell during winter conditions.
2. Maximum Smoke Temperature (Temperature Effect On Fire):
The Hyatt Regency Portland will be a fully sprinklered building. Sprinklers for the guest units and
corridors are 160F quick response sprinklers. Fires within guest rooms will be sprinkler controlled
fires, as the sprinkler system and room furnishings will be designed accordingly. As the fires will be
sprinkler controlled fires, the smoke layer temperature will be at or around the sprinkler activation
temperature. The smoke temperature entering the sub-ducted exhaust grille is assumed to be less
than 250F, given the 160F activation temperature of the quick response sprinklers. As the air
enters the shaft, the smoke will be diluted with air flow from the other eleven floors down to
approximately 85F by the time it reaches the top of the duct riser. Further dilution via combining with
other risers will also take place to keep the temperatures well below the rating of the exhaust fan
components of 110F. On the supply side of each guest unit a fire damper is provided at the shaft
wall. Fusible links for the supply fire dampers will have an activation temperature of 160F. The
activation temperature will be at the sprinkler activation temperature, as the airflow method will keep
air flowing over the fusible link so it will not activate at the same time or before the sprinklers, but will
have a quicker response time in case of a fire sprinkler failure. All fire dampers will be specified to
be dynamic type.
3. Wind Effect:
Exterior pressurization fan air intakes and stairway reliefs shall be located as remotely as possible,
considering horizontal and vertical distances as well as prevailing wind direction. Relief openings
shall be located at the top of the stair tower and located such that wind effect is minimized. Roof
hoods are omnidirectional and located behind parapet walls to block direct impingement of wind
pressures. Proximity of supply fan and exhaust fan intakes are a minimum of 20 feet apart, and the
exhaust fans are blowing away from intakes.
4. HVAC System:
To prevent the spread of smoke from HVAC systems, all air systems except for the hotel room
ventilation supply and the recirculating hotel room cooling and heating unit shall shut down during an
Hyatt Regency Portland Oregon Convention Center Smoke Control & Mechanical Design Narrative February 6, 2017 Page 5 of 17
alarm event. All HVAC systems required to shut down shall be shut down through a UL-864 listed
control system and shall comply with the requirements of section 907 of the OSSC.
The hotel room bathrooms are exhausted through a continuously operating central exhaust system
utilizing the sub duct exception of the OSSC, section 717.5.3. The central exhaust system shall be
provided with a legally required standby power system in accordance with the Electrical Code
Section and the OSSC. The hotel room exhaust airflow has been modeled in the CONTAM multi-
zone airflow/pressurization model.
The hotel room supply will operate continuously and will utilize the airflow method as mentioned
above. The supply velocity will prevent smoke from entering the duct per OSSC 909.5.2, Exception
2 (see Appendix for details of calculations for air flow quantities needed.) The central supply air
system shall be provided with a legally required standby power system in accordance with the
Electrical Code Section and the OSSC. The hotel room supply airflow has been modeled in the
CONTAM multi-zone airflow/pressurization model. The net impact on the stair pressurization system
is shown to be negligible since supply and exhaust are nearly identical in each hotel room.
5. Climate:
The smoke control system supply air intakes and relief openings shall be located minimum 2 feet
above the roof surface to prevent snow and ice blockage. ASHRAE outside design temperatures for
Portland (1% for cooling and 99% for heating) have been used when calculating the stack effect.
6. Duration of Operation:
The smoke control system is designed to operate a minimum of 20 minutes per OSSC 909.4.6.
PRESSURIZATION EQUIPMENT
1. Fans:
The belt driven fans shall have 1.5 times the number of belts required for the design duty (maximum
fan CFM) with the minimum number of belts being two (2) and fan motors have a minimum service
factor of 1.15. (Please note that the City of Portland Prescriptive requirement for a NEMA 1.25
service factor can only be obtained for motors of ¾ HP or less). Calculations and manufacturer’s fan
curves are part of the documentation procedures. The motor driving the fan shall not be beyond
their nameplate horsepower as determined from measurements of actual current draw. Power shall
be monitored downstream of all smoke control fan disconnect switches. Operation of the
pressurization fans in smoke mode shall be confirmed by positive indication with differential pressure
transmitters.
Fans shall be capable of withstanding the probable temperatures and pressures to which they are
exposed. Corridor post fire purge fan EF-HRU-2B shall withstand a minimu110F. This fan will be
exhausting the corridors post fire.
Fans shall be supported directly from fire-resistance-rated structural elements of the building by
substantial noncombustible supports. The fans shall be equipped with seismic vibration isolators.
Seismic tie-down calculations shall be provide by a Professional Engineer registered in the State of
Oregon. Minimum importance factor is 1.5 for the pressurization systems.
Provide shaft grounding for all fans with VFDs.
Pressurization systems shall be powered by an emergency power system conforming to OSSC
Section 403.4.9 and Chapter 27.
Hyatt Regency Portland Oregon Convention Center Smoke Control & Mechanical Design Narrative February 6, 2017 Page 6 of 17
The supply air shall be taken directly from an outside uncontaminated source at least 20 feet from
any air outlet, stairway relief opening, or source of contamination. The supply air intake shall be
located at the exterior of the building. The supply air intake shall be located minimum 2 feet above
the roof surface to prevent snow and ice blockage.
2. Variable Frequency Drives:
All pressurization fans, shall be equipped with Variable Frequency Drives (VFDs). The VFD shall be
capable of receiving multiple speed signals from the smoke control panel or fire alarm panel. The
drives shall be programmed to override other control signals when commanded by the fire alarm
system. Power to fans fed by VFD’s shall be monitored downstream for status.

Notes:
1) The damper and louver size shall be minimum 36”x36” and the louver shall be minimum 50%
free area. The counter balanced back draft damper shall be adjustable from inside the
stairway. The weight on the counter balanced backdraft damper shall be permanently fixed
in place after the final acceptance test. The relief louver or relief hood shall be located
minimum 2 feet above the roof surface to prevent snow and ice blockage.
2) The fan isolation damper shall be sized to accommodate Maximum Fan CFM.
3) All dampers shall be smoke dampers UL 555S and shall meet the Energy Code damper
leakage requirements. The dampers shall be spring open or spring closed as noted in the
table.
4. Ductwork:
Any duct or equipment in the building that is part of the stairway pressurization system shall be
protected with the same fire-resistance rating as required for the stairway shaft. No protection is
required for equipment that is located outside the building envelope (roof).
Duct materials and joints shall be capable of withstanding the probable temperatures and pressures
to which they are exposed.
5. 14th Floor Duct Protection:
Guest room supply and exhaust duct risers for floors 3 through 14 rise up in 2-hour rated shafts that
terminate at the underside of the 14th floor roof. The roof construction is post tension concrete and
while it is only required to be rated for 1-hour, its construction provides for 2-hours.
Hyatt Regency Portland Oregon Convention Center Smoke Control & Mechanical Design Narrative February 6, 2017 Page 7 of 17
Exhaust Ductwork:
Exhaust ducts use the sub-duct method for floors 3 through 14 which allows fire and smoke dampers
to be omitted per OSSC 717.5.3 Exception 1.1 and 2. On the 14th floor the exhaust ducts turn
horizontally and leave the shafts. The exhaust ducts combine together to route up to the HRU’s and
their associated life safety exhaust fans. Dampers are provided at the HRU to configure the system
so that during a fire, the exhaust air from all risers will get exhausted via a dedicated life safety
exhaust fan. This is done to isolate the exhaust from the supply air that is provided by the supply fan
in the HRU. The exhaust ductwork is constructed of galvanized steel and is routed from the exhaust
shafts, above the 14th floor gypsum board ceiling, and up to the life safety fan without any
intervening openings (see exhibit below).
Exhibit 2 – Dedicated Life Safety Exhaust Schematic
As the configuration does not allow the continuation of the exhaust sub-duct method on the 14th
floor, the design team is proposing to protect the openings at the shaft wall with through penetration
firestop assemblies per ASTM E814. Duct gauge thicknesses are noted on the enclosed plan and
exceed thicknesses required for the firestop listing. Fire dampers and/or smoke dampers in this
location could potentially compromise the exhaust portion of the smoke control system and cause
smoke to be pushed other portions of the building by the supply airflow, and failure closed of a
damper could potentially imbalance other dampers. Smoke dampers are proposed to be omitted per
OSSC 717.5.3 Exception 4, and fire dampers are proposed to be omitted on the 14th floor per OSSC
717.5.3 Exception 1.3 with the provision of through penetration firestop assemblies meeting ASTM
E814.
Hyatt Regency Portland Oregon Convention Center Smoke Control & Mechanical Design Narrative February 6, 2017 Page 8 of 17
Supply Ductwork:
Supply ducts leave their shafts at approximately 26 locations and combine together to route up
through the roof to the three HRU supply connections. The supply duct mains that feed guest room
supply risers also feed three supply risers that serve the corridors. Corridor supply risers are all
provided with fire smoke dampers at each grille on each floor. Corridor supply fire smoke dampers
will close during a fire to isolate the corridors.
Similar to the exhaust ductwork thought process for the 14th floor, the design team proposes to use
through penetration firestop assemblies where supply ducts enter the guest room supply shafts and
where they go through the shaft up to the roof. Fire or smoke dampers at the supply shaft
penetrations on the 14th could potentially reduce the effectiveness of the airflow method to the
rooms, or cause smoke migration to other portions of the building if the dampers close or fail at the
wrong time.
Smoke dampers are not provided at the top of the 14th floor supply shafts as actuation would
jeopardize the continuity of maintaining the pressure and velocity in the supply system. The current
design is proposed to provide a single duct detector in the supply at the HRU, with alarm and
manual override of the fan should it be necessary.
Firestopping of the ducts at the 14th floor supply and exhaust shafts has been proposed to be done
per ASTM E814 as part of the allowance to omit fire dampers at these locations. OSSC 717.5.3
Exception 1.2 allows fire dampers to be omitted when penetrations are tested in accordance with
ASTM E119 as part of the fire-resistance rated assembly. The proposed penetration protection is
using ASTM E814, which is a test for firestop systems of through penetrations for use in ASTM E119
assemblies. ASTM E814 uses the same time-temperature curve, furnace pressurization, and hose
stream test but does not have the same structural test as ASTM E119. As the ductwork will not be
providing structural support of the shaft, the ASTM E814 penetration protection has been proposed
to facilitate construction.
6. Post Fire Purge:
Per OSSC 404.3.7, smoke removal is required for post fire salvage operation. Smoke removal will
be accomplished at the guest rooms by using the center corridor relief shaft connected to a
dedicated relief fan. Supply air will be brought into the corridor via the HRU supply fans using the
three corridor supply shaft risers. OSSC 404.3.7 requires air movement of four air changes per
hour. This air change will be calculated based on the total area of the corridor plus the largest guest
unit. Switches on the Smoke Control Panel in the Fire Command Center will allow the smoke purge
mode for one floor at a time only, as selected by fire personnel.
