This report is intended to document the atrium smoke exhaust system testing performed
at the new Santa Rosa Plaza Embassy Suites Hotel located in the City of La Quinta,
California. This document also provides the necessary documentation required by
Section 905 of the California Building Code.
The Santa Rosa Plaza Embassy Suites Hotel retained Michael J. Madden, P.E., of
Hughes Associates, Incorporated, to provide the Special Inspection Services described
in Section 905.15 of the California Building Code. These services included
observations of the construction of smoke barrier walls, observation of the installation of
the fire alarm and detection system serving the atrium, preliminary testing of the smoke
exhaust system components, preliminary testing of smoke exhaust system operation,
and final testing of the smoke exhaust system and individual system components.
Associated Air Balance, Incorporated, provided air balancing services and provided
documentation of air flow velocities and air flow volumes as required by Section 905.15
of the California Building Code. The complete Air Balance Report for all HVAC systems
in the building is not included in this report, however the measurement of all air handling
equipment and components involved in the Atrium Smoke Exhaust System is provided
in Appendices D through F of this Document.
The originally proposed testing protocol is provided in Appendix A of this report.
2.0 FACILITY DESCRIPTION
The Embassy Suites is a new four-story building classified by the California Building
Code (CBC) as a Group R, Division 1 (R-1) Occupancy. The building has been
constructed with a 6,900 ft2 atrium extending from the ground floor through the fourth -
level (4-stories). The atrium is separated from adjacent guest room spaces by one -hour
fire resistive construction with protected openings. Exit access balconies around the
atrium are open to the atrium space at all levels. In addition, the exit access corridor to
the first floor conference/meeting rooms is also open to the atrium space. Per CBC
Section 402.2, the atrium and areas open to the atrium must be provided with a smoke
control system complying with the requirements of CBC Section 905.
CBC Section 905 provides requirements for the design of smoke control systems
intended to provide a tenable environment for the evacuation or relocation of occupants.
The exhaust method was chosen for the Embassy Suites project, which is typically the
method applied to atria or large space applications. The goal of a smoke control system
designed using the Exhaust Method is to maintain the smoke layer interface of the
HUGHES ASSOCIATES, INC.
Atrium Smoke Exhaust System Testing October 20, 2006

accumulating smoke layer at least 10 feet above any walking surface in the smoke
zone. In order to accomplish this goal on this project, a mechanical smoke exhaust
system has been provided to maintain the smoke layer at a height of 43'-2" above the
finished floor, which is 10 feet above the highest walking surface within the atrium (0
floor balcony).
The mechanical smoke exhaust system provided for the project includes the following
features:
1. The system provides 180,000 cfm of total exhaust for the removal of smoke and
other products of combustion. The exhaust system consists of sixteen (16) exhaust
inlets (four in each skylight).
2. Outside air is supplied to the atrium to make up approximately an equal volume of
air exhausted. Make-up air will be a combination of forced air, and natural/free
openings.
3. The fire alarm and detection systems for the building are zoned to facilitate the
correct sequencing and activation of the smoke control system. The smoke
exhaust system has been arranged for automatic activation, and by manual
activation at the Firefighters Control Panel.
4. An Underwriter's Laboratories (UL) UUKL Listed smoke control panel is provided in
the Fire Control Room. The panel has been arranged to provide manual override,
and manual control of smoke control system components, as required by the
California Building Code.
5. The system is supervised for positive confirmation of activation (i.e. fans, dampers,
automatic doors, etc.), testing of devices, manual override mechanisms, and the
presence of power downstream of all disconnects. Conductors and connections
which interconnect equipment, devices, and appliances are monitored for integrity in
accordance with NFPA 72, as adopted by the State of California.
6. All exhaust fans are rated and certified by the manufacturer for temperatures up to
1440F or higher. In addition, all belt -driven fans have 1.5 times the number of belts
required for duty, or a minimum of two.
7. All electrical components of the smoke control system are provided with a standby
power source in accordance with CBC Section 905.8.
8. All of the smoke exhaust system equipment meets the applicable provisions of
Section 905 of the CBC.
The Atrium Smoke Control System Design Report, prepared by Gage -Babcock &
Associates, has been provided in Appendix B of this report.

The building is divided into two smoke zones, for the purpose of operating the smoke
control system. These zones are referred to elsewhere in this report and the Rational
Analysis Report as Zones 1 and 2. These smoke zones are defined as follows:
Zone 1 - The atrium space and all areas open to the atrium.
Zone 2 - The remainder of the building not open to the atrium.
The automatic activation of the smoke control system is accomplished through actuation
of smoke detection in the atrium smoke zone (Zone 1). The system does not actuate
upon actuation of a manual pull station. Once activated the system remains running
until manually overridden at the fire department control panel.
A smoke detection system is provided throughout the atrium space. This is has been
accomplished by providing system smoke detectors in all corridors, lobbies, and
balcony areas open to the atrium, and providing a projected -beam smoke detection
system installed at the 4th floor level at approximately 33 feet above the atrium floor.
The beam detectors are installed so that they project a beam horizontally across the
atrium floor opening and with maximum beam spacing (between parallel beams) of
approximately 8.25 feet. All devices are UL listed and installed per the listing, NFPA 72,
and manufacturer's recommendations.
The building is provided with a fire alarm notification system to initiate evacuation of the
building in a fire emergency. The fire alarm notification system, when initiated, is
audible throughout the building. The alarm system includes both audible and visual
alarms located in accordance with the Fire Code, NFPA 72 and ADA requirements.
The fire alarm and detection system is zoned to facilitate the activation of the smoke
control system, as described above. The atrium zone (Zone 1) will include the atrium
space and all areas open to the atrium which includes the main entrance lobby, the
balconies/walkways around the perimeter of the atrium, and corridors to the
meeting/conference rooms on the 1 st floor.
A smoke barrier, consisting of one hour fire rated construction with protected openings,
is provided to separate all adjacent areas from the atrium.
3.0 SMOKE ZONES AND SMOKE BARRIERS
As indicated above, the building is divided into two smoke zones to accommodate the
j atrium smoke exhaust system. Zone 1 includes the atrium, and all areas open to the
J atrium atmosphere. The remainder of the building, beyond the atrium smoke barrier
walls, is considered Zone 2.

A smoke barrier provides the separation between Smoke Zone 1 and Smoke Zone 2.
This smoke barrier is required to comply with the requirements of Section 905.2 of the
California Building Code.
The inspection of the construction of the smoke barrier wall was included under the
Special Inspection requirements for the project. Several site inspections were made
1 during the course of the construction to verify that the construction of the smoke barrier
walls was proceeding in accordance with the requirements of the Code.
Physical inspections of the smoke barrier wall construction were made on the following
dates:

These inspections involved reviewing wall framing installations, drywall installation,
taping, and sealing, penetration and joint sealing, and the installation of the fire rated
glazing assemblies and 20 minute fire -rated smoke and draft control door assemblies.
During the construction, a significant portion of the guest room smoke barrier wall
installation had to be redone due to drywall getting wet prior to the atrium roof being
finished. The re -installation of the drywall in these areas was also reviewed for
J compliance with the applicable requirements of the Building Code.
The smoke barrier walls separating the atrium guest rooms from the atrium are in
compliance with the requirements of Section 905.2 of the California Building Code. The
construction of the walls consists of a one -hour steel framed, gypsum board fire -rated
wall assembly. Drywall joints are staggered, and all joints are taped and sealed. Joints
floor and ceiling have been protected with an approved fire rated sealing material. The
Firelite fire rated glazing assemblies have been installed in accordance with the listing
requirements, and the manufacturer's instructions. The doors self -closing, 20 minute
fire -rated smoke and draft control door assemblies. All penetrations of these smoke
barrier walls have been protected using approved penetration protection methods.
On the first floor of the atrium, the smoke barrier wall separates the atrium from the
meeting rooms, the Administrative Office areas, the Health Club, and the main kitchen

area. The smoke barrier wall typically involves a one -hour steel framed, fire -rated
gypsum board wall assembly, with 20 minute fire -rated smoke and draft control door
assemblies. All doors in these smoke barrier walls are either self -closing, or automatic
closing door assemblies.
In the kitchen area, the smoke barrier wall runs between the front cooking line and the
back kitchen area. This wall has been constructed as a one -hour assembly, and has
been installed with a tile facing to accommodate the cooking operations on both sides of
the wall. In this wall, however, two bi-directional, metal swinging doors (non -fire rated)
have been installed to facilitate movement between the kitchen and dining room area.
These doors do not comply with the original design intent of the smoke barrier wall
assembly.
In reviewing the impact of these doors on the performance of the smoke exhaust
system, calculations have been performed to identify the leakage areas involved with
these non -protected door openings. In addition to the calculations performed, airflows
and airflow velocities through these door openings were measured during smoke
exhaust system operation. These air flow measurement results, and the leakage
calculations performed for this portion of the first floor smoke barrier wall, are provided
in Appendix C.
The calculations in Appendix C calculate the leakage area to wall area ratio as
stipulated in Building Code Section 905.2.3. Estimates were provided for the leakage
around all doors in the smoke barrier, and actual leakage measurements were used to
reflect leakage around the two bi-swing kitchen doors. The calculations performed
show that the leakage around the kitchen doors, plus the leakage area estimated for all
other doors in the smoke barrier wall on the first floor, do not exceed the allowable
leakage area to wall area ratio specified in Building Code Section 905.2.3.
As seen from the air flow measurements at these doors under both open and closed
conditions, the airflow through these doors is not really significant given the amount of
make-up air flow provided into the atrium. It should also be noted that the doors are not
pulled open by the smoke exhaust system when the system is operated.
4.0 COMPONENT TESTING
Testing of the smoke control system components, including fans, dampers, controls,
and fire alarm systems, began in July of 2006. At that time, the mechanical equipment
installation had been completed, and the fire alarm system work was nearing
completion. Operational testing of the system components were performed by Hughes
Associates personnel, with the assistance of the Fire Alarm and Mechanical System
contractors and Embas v uites ersonnel. Actual measurements of component

The RTU-25a and RTU-25b air handlers supply conditioned air to the atrium space
under normal conditions. These fans are normally controlled by the building energy
management system, however under fire conditions, the unit controls are overridden by
the fire alarm system.
These air handlers and their supply registers in the atrium are balanced for the normal
air conditioning operation. Under atrium fire conditions, these fans will continue to run
or they will be started up, to provide make-up air at the first level of the atrium. To
reduce velocities from the slot registers at the side of the atrium, normally closed fire
dampers will open up, diverting some of the air flows to three more ceiling registers.
The results of the airflow and velocity measurements made by Associated Air Balance,
under full atrium exhaust system operation, for the RTU-25a Supply air Registers, are
summarized in the following performance tables:

Based on the test results indicated above, several of the slot registers and ceiling
registers have outlet velocities that exceed the design value of 200 feet per minute
(values indicated in red). The 200 foot per minute design parameter is based on
Section 4.6.4 of NFPA 92B, Smoke Management Systems in Malls, Atria, and Large
Spaces. Section 4.6.4 states that "the make-up air velocity shall not exceed 200 ft/min
where the make-up air could come into contact with the plume unless a higher make-up
air velocity is supported by engineering analysis". The 200 ft/min limitation is intended
to prevent significant plume deflection and disruption of the smoke interface.
The location of the ceiling dampers in the atrium with face flow velocities greater than
200 ft/min are not in locations where the plume or smoke layer would be disrupted.
With these ceiling dampers, the velocity would decrease rapidly as the air flow moves
beyond the register.
Similarly, the velocities from the slot registers will rapidly decrease as the airflow moves
out from the register. In this situation, it does not appear that these velocities would
significantly deflect the plume and disrupt the smoke layer interface.
The flow measurements performed for the RTU-25a and RTU-25b make-up air systems
are documented in Appendix F of this report.
As indicated above, normally closed dampers in the RTU-25a and RTU-25b distribution
duct work open up under atrium smoke exhaust conditions to divert airflow to additional
registers, to reduce air flow velocities at the slot registers.
These dampers were tested for proper operation and proper closure times during the
component testing performed. The results of these tests are presented in the following
tables:

Additional make-up air is provided through natural airflows through operable doors and
windows on the first floor level, and by make-up air louvers on the second, third, and
fourth floors.
Upon activation of the smoke exhaust system in the atrium, the operable doors and
windows on the first floor open up to allow for natural make-up air flow into the atrium.
At the same time, the outside air louvers at the end of the atrium corridors on floors 2, 3,
and 4 open up, allowing make-up air to flow down the corridor.
Make-up air supplied to the second, third, and fourth floors is by way of these outside air
damper and louver assemblies. The control dampers are provided at the exterior wall,
and additional louvered panels are provided inside of the damper location. The
effective area of the outside air dampers were confirmed to be approximately 30 square
feet in area, while the inside air louvers were confirmed to have an effective area of
approximately 17 square feet. These opening areas are consistent with the design
intent.
The operational testing of the system verified proper operation of the make-up air
openings.
Associated Air Balance personnel performed air flow and velocity measurements at
these make-up air openings. Their measurements are summarized in the following
tables:

For the make-up air openings indicated above, the face velocities exceed the 200 ft/min
guideline provided in NFPA 92B. These openings, however, are remote from the main
atrium space, and the velocity of air flow from the lobby area into the atrium will be
substantially less than the 200 fpm requirement.
Air Flow and velocity measurements were also taken at the outside make-up air louvers
at the end of the guest room corridors on floors 2 through four. Measurements were
taken at the outside air damper, at the inside louver, and additionally, velocity
calculations of air flowing down the corridor into the atrium space were performed to
identify air flow velocities at the atrium.
The results of the Associated Air Balance measurements at these make-up air openings
are summarized in the following table:

The total make-up air flows from the corridor outside air louvers is 27,809 cfm. As you
can see from the above table, even though the face velocity at the inner louver exceeds
200 ft/min, the velocity of the airflow as it flows into the atrium from the corridor is less
than the 200 ft/min limitation in the Code.
The flow measurements taken by Associated Air Balance during Smoke Exhaust
system operation are documented in Appendix G of this report.
5.0 SYSTEM FUNCTIONAL TESTING
In addition to the component testing discussed above, the smoke exhaust system was
functionally tested to verify system operation and control functions were in accordance
with the design intent, and in accordance with the requirements of the Building Code.
A The functional testing included inspecting the operation of all fans, dampers, make-up
air doors and louvers, and reviewing system supervisory features, Smoke Exhaust
JSystem Control Board functions, and status indications. Hughes Associates personnel,
along with representatives of the Building Safety Department and Fire Department
participated in functional testing of the system on August 15, 2006.

During the testing, the smoke exhaust system was activated using fire detection devices
provided in the atrium, specifically the spot -type smoke detectors located in the lobby
and the perimeter of the atrium, and the projected -beam smoke detectors located at the
fourth floor level in the atrium. The response of the system controls to these detector
activations was in accordance with design requirements.
Upon smoke exhaust system activation, the roof -top exhaust fans were confirmed to
start and continue to operate until the system was reset. The fans started immediately,
well within the 15 second start-up time dictated by Section 905.14 of the Building Code.
Full fan output was witnessed to be achieved after about 15 to 20 seconds of fan
operation, which is within the time limits specified in the Code. In addition, power
supplies to the fans were disconnected to verify fan power supervision features.
Upon smoke exhaust system operation, it was verified that the make-up air louvers
provided at the ends of the open corridors at the second, third, and fourth floor levels
opened as intended, and remained open until the system was reset. When the system
was reset, the louvers closed and assumed their normal status position.
The make-up air doors and windows on the first floor were verified to open and remain
open during system operation, and to assume their closed, normal operating condition,
upon system reset. Doors and windows began to open immediately upon system
activation, well within the 15 second time limit specified in the Building Code. Doors
and window openings achieved their full open position within approximately 15 seconds
of operation.
The Smoke Exhaust system was also tested under emergency power conditions, in two
ways. First off, the smoke exhaust system was activated through the activation of a
lobby level spot -type smoke detector (using the magnet test procedure). When all of
the fans and other components were in full operation, the main power was
disconnected. The emergency generator started up, and picked up the smoke exhaust
system power loads, to include all exhaust fans and make-up air fans.
With the main power disconnected, and the smoke exhaust system reset to its normal
standby mode, the system was activated automatically. The system went to full
operational status on emergency power, to include the operation of all exhaust and
make-up air fans, control dampers, make-up air door, window, and louver operators,
and functions at the Firefighters Smoke Exhaust System Control Board.
The operation of the Smoke Exhaust System Control Board was also reviewed, and the
functions provided with the required On -Off -auto switches were tested for proper
functioning. --

The RTU-25 air handlers that provide make-up air to the first floor level upon smoke
exhaust system operation are also arranged to provide continuous ventilation for the
atrium area. These units are set up to run continuously to provide ventilation, and they
are provided with cooling and heating coils for temperature control. These units are
supervised by the smoke exhaust system panel. If these units are programmed "off', a
supervisory "fault' condition is indicated at the smoke exhaust system control panel.
RTU-25 supervisory conditions were verified during the smoke control system testing.

1.0 PROJECT SCOPE I f
Gage -Babcock & Associates was contracted to provide fire protection engineering and
code consulting support for the design of the atrium smoke control system proposed at the
Embassy Suites located In La Quinta, California.
The Embassy Suites is a new four-story building classified by the Califomia Building Code
(CBC) as a Group R, Division 1 (R-1) Occupancy. The building is being proposed with a
6,900 ftz atrium extending from the ground floor through the fourth -level (4-stories). The
atrium is proposed to be separated from adjacent spaces by one -hour fire resistive
construction with protected openings at all levels as required by CBC Section 402.3. Exit
access balconies around the atrium are not separated from the atrium space at all levels.
Per CBC Section 402.2, the atrium and areas open to the atrium must be provided with a
smoke control system complying with the requirements of CBC Section 905. Per CBC
J Section 905, smoke control systems shall be based on a rational analysis in -accordance
with well -established principals of engineering.
This Design Report is intended to serve as the "Rational Analysis" for the proposed system
and provide relevant design criteria for design and installation of all systems and
construction features integral to the performance of the smoke control system:_ This report
is intended 'tor review and approval by the City of La Quinta Building Department and
Riverside County Fire Department. All designs should be reviewed for compliance.,with
applicable code requirements and the specific requirementstrestrictions outlined in this
report. Any deviations from the recommendations in this report will require review and
approval by Gage -Babcock or similarly qualified person/firm approved by the City of La
Quinta and Riverside County.

3.0 DESIGN METHOD
CBC Section 402.2 requires that the atrium and arras open to the atrium be provided with
a smoke control system complying with the requirements of CBC Section 905.. CBC
Section 905 provides requirements for the design of smoke control systems Intended to
provide a tenable environment for the evacuation or relocation of occupants. CBC Section
905 allows systems to be designed using one of the following methods:
• Pressurization Method
• Airflow Method
• Exhaust Method
The exhaust method was chosen for this project, which is typically the method applied to
atria or large space applications. The goal of a smoke control system designed using the
Exhaust Method is to maintain the smoke layer interface of the accumulating smoke layer

at least 10 feet above any walking surface in the smoke zone. In order to accomplish this
goal on this project, a mechanical smoke exhaust system Is being provided to maintain the
smoke layer at a height of 43'-2" above the finished floor, which is 10 feet above the
highest walling surface within the atrium (4t' floor balcony).
To determine the required exhaust capacity of .the mechanical exhaust system, the plume
mass flow rates (smoke generation) for the plume configurations applicable to this specific
project must be calculated. There are three typical plume configurations that must be
considered when using the Exhaust Method, which are outlined in CBC Section 905.5, and
they are:
• Axisymmetric
• Balcony Spill
• Window
Not all of these configurations are applicable for all projects. Each has very specific
applications and restrictions and each must be evaluated as to their suitability for the
specific project. In the sections to follow, each configuration is, discussed, and evaluated.
3.1 Axisymmetric Plume
An axisymmetric plume is expected for a fire originating on the atrium floor, removed -from
any walls. In this case, air is entrained from all sides and along the entire height of the
plume until the plume becomes submerged in the smoke layer. The mass rate of smoke
production is calculated, based on the rate of entrained air, using the equations shown
below from CBC Section 905.5.2.2.
For z > zl mp = 0.022Q,"3z513 +0 0042Q�
(1)
For z < z, mp = 0.0208Q,311z
where:
Q = total heat output (fire size), BTU/s
QC = convective heat output, BTU/s (taken as 0.70Q)
z = height of smoke layer interface above fire, feet
z! = limiting flame height, feet = 0.533QQ2, s
These equations for the mass flow of axisymmetric plumes do not apply if obstructions

-' proposed atrium, the plume will not be obstructed unless it becomes wide enough to
contact the edge of the balconies. Calculating the plume diameter using the equation
below from CBC Seaton 905.5.2.5 can check this.
d = 0.48[(T,; +460)/(Ta +460)1" z (2)
where:
d = plume diameter, feet
TQ =ambient air temperature, 'F
T, = plume center line temperature, °F = (318Qe2/3H-513 )+ T.
z = height at which T. is determined, feet
Based on the specifics of this project a design fire of 5,000 BTU/s (Q=3,500 BTU/s) and an
ambient temperature of 68°F (inside temperature) will be used (See Appendix D for
calculations relating to the desic,�n fine for the axisymmetric plume scenario). The plume
diameter is calculated at the 4 floor balcony level (337) _to see if the plume will be
obstructed, using Equation 2. _.

= 282° F
d = 0.48[(282 + 460)/(68 + 460)1'2 (33.167)
=18.9 feet
At the highest balcony level the plume is calculated to be 18.9 feet in diameter and the
opening at that level is approximately 59' X 57'. Therefore, an axisymmetric plume is valid
for this project and it can be assumed that the plume will not contact the walls.to confine
the flow.
3.2 Balcony Spill Plume
A balcony spill plume is one that flows under and around a balcony before rising, giving the
impression of spilling from the balcony, from an inverted perspective. The equation for the
mass rate of smoke production from a balcony spill plume is found in CBC Section
905.5.2.3. The mass flow rate is determined using the geometrically probable width based
on architectural elements and projections using the following equation:

The atrium contains geometry that may produce balcony spill plumes. Therefore, this

3.3 Wil dow Plume
A window plume is one that flows through an opening, such as a door or window, from a
room into a large -volume open space. For this project, there are rooms adjacent to the
atrium with doors and windows that open into the atrium space. However, the wall
separating these spaces from atrium will be fire resistive construction with self -closing rated
doors and fire rated windows. A window plume will only be valid if: the glass window is
expected to break -due to a fire in these separated spaces. The building will be protected
throughout with sprinklers; therefore it can be evaluated -using modeling whether a
sprinkler -controlled fire would produce enough heat to break a fire rated window.
i
A compartment fire model was run using CFAST to determine if the glass: window may
break for this project. The model was run using a- moderate t squared fire with a maximum
fire size determined based on sprinkler activation. The upper layer temperature was
recorded and compared to the exposure temperature curve used to test fine rated windows.
The results below show that the temperatures the glass window is exposed to in a sprinkler
controlled fire on this project are well below the exposure temperatures for testing and it
can be expected that the glass will not break during the typical time frame a smoke control
system is expected to perform. (See Appendix D for additional modeling input/output)
Therefore, consideration was not given to window plumes for this project.

4.0 ANALYSIS
As identified above, the approach selected for the smoke control system design is the
! _ exhaust method. To design this type of system, several calculations and possible effects
must be completed to ensure proper performance of the system. In the sections to follow,
appropriate calculations and results are outlined, and relevant design factors are
-_� considered. The final design criteria based on this analysis is summarized below in Section
11 5.0.
4.1 Exhaust Calculations
Based on the design approach selected, the goal of our system is to provide mechanical
_ smoke exhaust with the capacity to remove smoke from the atrium to maintain the smoke
_l layer interface at a predefined height in the space for an indefinite .period of time. To
1 accomplish this goal, the system must exhaust the same quantity as the smoke produced
by a .fire with the smoke layer interface at that predefined height.
1 In Section 3.0, the different plume configurations and their applicability to this project were
discussed. For this project, the axisymmetric iplume and balcony spill configurations were
1 proven to be applicable. Therefore, the system as a minimum must have a total .exhaust
J capability equal to the mass rate of smoke production calculated for -these plume
configurations.
Using Equation 1 found in Section 3.1 above, the smoke mass production rate is calculated
for the axisymmetric plume scenario. The same design fire used in Section 3.1 above will
be used, 5,000 BTU/s (Q,=3,500 BTU/s), and the smoke layer interface height (z) will be
43'2" (10 feet above the highest walking surface) as required by Code.

MP
= 0.022(3500Y"(43.167)5/3 +0.0042(3500)
=1921b/s
Based on the results, the system must provide at least 192 Ib/s of exhaust to maintain the
smoke layer at the design height for an axisymmetdc plume scenario. This quantity can be
converted to a volumetric rate using the equations below from CBC Sections 905.5.2.2 and
905.7.2.

determined to be 174,545 cfm.
v = 60(192)/ 0.066
=174,545 cfin
Using Equation 3 found in Section 3.2 above, the smoke mass production rate is calculated
for the balcony spill plume scenario. The fire scenario representing the worst case smoke
production is on the first floor. Based on the Irchitectural design of the first floor ceiling the
spill width (W) is assumed to be 10 feet (see Architectural RCP fro detail). The fire size
used for this calculation is 625 BTU/s, which was determined based on sprinkler activation
using ...(See Appendix D). The height of the balcony (H) used in the calculation was 9'-10"
and the distance from the balcony to the smoke layer interface (zb) was 33'-4°.
mp = 0.124(625 x 102 Y" (33.33 + 0.3 x 9.83X1 + 0.063(33.33 + 0.6 x 9.83)/ 10f 13
= 2081b/s
The mass flow rate is then converted to a volumetric rate similar to the axisymmetric plume
using a smoke temperature of 79°F and density of 0.074 IWO.

Based on the results of each plume configuration the system must be capable of a
minimum exhaust rate of 174,545 cfm.
4.2 Number of Exhaust Inlets
The exhaust fan inlets should be sized and distributed in the space to be exhausted to
minimize the likelihood of air beneath the smoke layer from being drawn through the layer,
a phenomenon sometimes referred to as `plugholing". To accomplish this, the velocity of
the exhaust inlet should not exceed a value to cause fresh air to be drawn into the smoke
layer. The CBC does not provide equations or other guidance on this design aspect.
Therefore, equations from NFPA 92BYwere used. The maximum volumetric flow rate that
can be exhausted by a single exhaust inlet without "plugholing" is:
V. = 0.537,6d 112 [TQ (T, —Ta )T iz (6)
where: 7

Using the smoke temperature calculated earlier of 1440F (6040R), an ambient temperature
of 68°F (5280R), smoke layer depth of 5 feet (see Atrium section in Appendix A), and an
exhaust location factor of 2.0, the maximum flow without plugholing can be calculated. The
exhaust location factor was selected based on the suggested value for wall exhaust inlets
near a ceiling.
V. = 0.537(2.OX5)"' [528(604 — 528)1"
=12,026 efm
The maximum volumetric flow rate for an exhaust inlet is 12,026 cfi n, based on the required
total exhaust of 174,545 cfm a minimum of 15 inlets are required. For purposes of
symmetry, 16 inlets will be provided on this project each exhausting 11,250 cfm for a total
of 180,000 dm.

When the exhaust at an inlet is near this maximum flow rate, adequate separation between
exhaust Inlets needs to be maintained to minimize Interaction between the flows near the

rectangular exhaust inlets, D = 2ab/(a + b), where a and b are the length and width of -the
inlet. Based on the specifics in this project the effective diameter of the inlets must be less
than 2.5 feet to comply with this recommendation.
4.3 Stack Effect
The code requires that smoke management systems be designed such that the maximum
probable normal or reverse stack effect will not adversely interfere with the system's ability
to function as designed. The proposed system is based on an exhaust method of smoke
control and does not use pressure differences to control smoke. Therefore, once the
J system has been operated the smoke movement driven back either normal or reverse
stack effect will be eliminated. To ensure that the system will perform as designed the
exhaust and supply fans will need to be selected to compensate for the pressure difference
caused by stack effect.
During winter conditions, the atrium will be warmer than the outside air causing a normal
stack effect where the airflow in the building will be in an upward direction with air flowing
into the building below the neutral plane and out of the building above the neutral plane.
This will not have a negative effect on the systemtfan performance except for supply fans

located above the neutral plane, which will need to counteract the positive pressure
� difference trying to force air out of the building.. To determine the magnitude of the
pressure difference caused by normal stack effect, the location of the neutral plane must be
determined and then based on the distance and direction from neutral plane the pressure
differenoe can be estimated.
Based on a winter temperature of 26OF (4860R) and an inside temperature of 68OF (5280R)
- the neutral plane location is calculated as follows:

direction based on the distance above or below the neutral plane. Since we are only
concerned with the effect on supply points above the neutral plan for normal stack effect
the pressure at the 4th floor calling elevation ' will be used, since all make-up air will be
supplied below this point. Using an elevation above the floor of 40'6" the pressure
difference is calculated below:

4.4 Temperature Effect of Fire
CBC Section 905.2.2.3 requires that the buoyancy and expansion relating to gases
produced by the design fire be addressed. The impact of the buoyancy and expansion of
hot combustion gases was analyzed for this design -as follows:
1. As a result of using an exhaust system, gas expansion is not -a concern because
the exhaust system will not allow any pressure to build-up in the space.
2. The system has been designed accounting for the worst -case change in density
as a result of temperature increase from the design fire.
3. Buoyancy is addressed by evaluating smoke stratification issues for this design.
Once the smoke evacuation system' has started in for the atrium, the stratification
condition (if present) will be eliminated by removal of the hot layer. The problem
facing is to ensure that the presence of smoke is promptly detected. To account
for ensure appropriate detection and activation of the system a specifically
designed detection system is being proposed. (See Section 4.8 for details)
4.5 Wind Effect
CBC Section 905.2.2.4 requires that the adverse effects of wind be considered in the
design of a smoke control system. In many instances, wind can have a pronounced effect
on smoke movement within a building. The effect of wind on air movement within tightly
constructed buildings with all doors and windows closed is slight. However, the effects of
wind can become important for loosely constructed buildings or for buildings with open

doors or windows, The building will be tightly constructed and all spaces are separated
from the atrium so wind effects will be minimal. When the system is activated, because the
exhaust method is being employed on this project, the driving force for smoke movement in
the building will be the ventilation (exhaust) system. Given the size of the exhaust system,
any wind driven smoke flow will be over powered by the forced exhaust.
A final consideration is the location of the exhaust outlets and supply air intakes. Inlets and
outlets must be configured so that smoke is not reintroduced into the building by the smoke
control system. Therefore, all inlets will be upwind of outlets under prevailing wind
conditions, which is Northwest, or otherwise located to reduce the possibility of drawing
smoke back into the building.
4,6 HVAC SYStems
CBC Section 905,22.5-- requires that consideration be given to the effects caused by
heating, ventilation and air-conditioning (HVAC) systems on the smoke production and
transport. The design for this project requires that the building HVAC systems (excluding
guest room stand alone units) shut down upon the detection of a fire to eliminate any
effects caused by its operation, In addition, all smoke barriers must be provided with
smoke dampers in accordance with CBC Section 713.10.
The kitchen exhaust fans located within the: atrium enclosure will not be controlled by the
smoke exhaust system. If these fans are running during an atrium system activation, they
will continue to run. In our opinion, the impact of these fans on the performance of the
atrium exhaust system is negligible.
In addition, to effects cased by the HVAC system the effects of the fire on equipment used
for smoke exhaust must be addressed. The exhaust fans must be rated and certified for
the probable temperature rise that they May be exposed. Previously, the smoke
temperature was calculated to be 144OF in accordance with the calculation found in CBG
Section 905.7.2. Therefore, to account for the effects of a fire and ensure continued
operation of the smoke control system the exhaust fans must be rated for operating
temperature greater than 144°F.
4.7 Climate
CBC Section 905.2.2.6 states that the effects of low temperatures on systems, property
and occupants shall be considered. In addition, the code states that air inlets and outlets
associated with the smoke control system, where applicable, shall be located to prevent
snow or ice blockage.

The proposed location of the project is not subject to extreme cold temperatures that will
require special measures to protect the system, property, or occupants from low
temperatures. Also, the proposed location does not require special attention to prevent
snow or ice blockage. Other climate considerations have been addressed elsewhere in this
report.
4.8 Stratification and Detection
When the temperature of the air in the upper portion of the atrium space is greater than that
at lower levels, smoke can stratify under the hot layer of air and not reach ceiling.
Stratification is only a concern with the exhaust method prior to activation of the system,
since the exhaust system will remove any heated air from the top of the atrium upon
activation. Therefore, smoke stratification must be accounted for the early stages of the fire
this will be done by ensuring that proper detection and activation of the system will occur.
Due to the high ceiling in the atrium, sprinkler activation is not an effective method for
activating the system. As a result, smoke detection is proposed as the means for activating
the smoke control system. To help ensure, that a fire is detected early and that the
detection is not significantly affected by stratification horizontal beam detection is being
added to the atrium to detect the smoke plume. The purpose of this approach is to detect
the rising plume rather than the smoke layer. For this approach,, an arrangement of beams
' close enough to each other to assure intersection of the plume is installed. The spacing
between beams shall be based on the narrowest potential width of the plume at the level of
detection. The spacing of these beams, as suggested by NFPA 92B, shall be calculated
using the following equation:
d = 025z
where:
(10)
d = minimum plume diameter/beam spacing, ft
z = height above fire, ft
a
J The proposed height of the beam detectors is at the 0 floor level (33' AFF), solving the
above equation the maximum beam spacing (between parallel beams) shall be 8.25 feet.
Based on this proposed height of the beams, we must ensure that the plume will rise
(overcome stratification) to reach the detection with a small enough fire size (i.e. early
stages of the fire), Using the formula below we can solve for the maximum temperature
change above ambient conditions that would prevent smoke from reaching our detection
system for a given fire size.

A very important piece of any smoke control system is proper activation sequencing. tf the
sequencing is not con-ed, the system may not function properly and may not achieve the
intended objectives. The following describes the recommended activation sequencing for
the smoke control system in order to facilitate the goals of this project.
The building should be divided into a minimum of two smoke zones, for the purpose of
operating the smoke control system. These zones will be referred to as Zones 1 and 2.
These smoke zones are defined as follows:
Zone 1 - The atrium space and all areas open to the atrium.
Zone 2 - The remainder -of the building not open to the atrium.
The automatic activation of the smoke control system ' will be accomplished through
actuation of smoke detection in the atrium smoke zone (Zone 1). The system shall not
activate upon actuation of a manual pull station. Once activated the system will remain
running until manually overridden at the fire dcparbnent control panel. In addition, .an alarm
in any zone will shut down all normal HVAC operations for the building. f
5.2 Fine Sprinkler Systwn
The Building Code requires that any building with an atrium be protected -throughout: by an
automatic sprinkler system. The sprinkler system must be designed and installed in
accordance with NFPA 13. The building will have a sprinkler system installed throughout
- with quick response sprinklers installed in the atrium and areas open to the atrium as
required for Light Hazard Occupancies by'NFPA 13 (other areas may require quick
i response sprinklers based on code requirements). There is no special design
J requirements or restrictions for the sprinkler system as a result of the smoke control system
analysis.
All valves controlling the water supply and water flow switches should be electrically
monitored. Monitoring should consist of distinctively different alarm and trouble signals
being automatically transmitted to an approved central station, remote station, or
proprietary monitoring station. No special zoning of the sprinkler system is required for
activation of the smoke control system.

5.3 Fire Alarm and Detection System
The Building Code does not specffically require a detection system due to the presence of
the atrium. However, Gage -Babcock has recommended that the automatic activation of the
smoke control system be controlled using smoke detection in the atrium. Therefore, as a
minimum, a smoke detection system covering the atrium space (excluding the skylights)
and all areas open to the atrium shall be provided. Any detection devices meeting the
requirements of the Building and Fire Codes may be used for this system. In addition to
this protection, a specialized beam detection system must be install at the 41i floor level at
approximately 33 feet above the atrium floor. The beam detectors shall be installed so that
they project a beam horizontally across the atrium floor opening and with a maximum beam
spacing (between parallel beams) of 8.25 feet. All devices shall be UL listed and installed
per the listing, NFPA 72, and manufacturers recommendations.
The building shall be provided with a fire alarm notification system to -initiate _evacuation of
the building in a fire emergency. The fire alarm'notification system, when initiated, shall be
audible throughout the building. The alarm system should include both audible and visual
alarms located In accordance with the Fire Code, NFPA 72 and ADA requirements..
The fire alarm and detection system must be zoned to facilitate the activation of the smoke
control system, as described above. The atrium zone (Zone, 1,) :will ;include the -atrium
space and all areas open to the atrium, which includes balconiestwaikways,around-the
perimeter of the atrium. The central monitoring station shall supervise the fire alarm
system including the smoke control system.
5.4 Construction
The intent of this analysis is not to prescribe any alternate to the building construction
required by the Code. However, there are somb assumptions relating to the location of fire
resistive construction and smoke barriers that need to be addressed (See Architectural
Dwgs). The analysis assumes that one -hour fire rated construction separates all adjacent
areas from the atrium. The three stair towers are enclosed to the exterior by two-hour fire
rated construction. It is also assumed that the atrium separation will also act as smoke
barriers and comply with CBC Section 905.2.3.

It was the intent of this analysis to not limit the atrium fuel loading beyond its typical use or
the restrictions present in the fire code. Therefore, in the open area of the atrium (i.e. high
ceiling areas not adequately protected by sprinklers) furnishings and decorative materials
must not exceed a potential heat of combustion of 9,000 BTUAb in compliance with CFC
Section 1103.3.4.1. Decorative materials within the atrium shall be noncombustible, flame
resistant or treated with flame retardant.

Axis nie#rr`c Plume:
The design fire for the axisymmetric plume was arrived at using , the Sprinkler effective
assumption allowed by CBC 905.6.2.4. Using the computer model CFAST Version 3.1.7
predictions for sprinkler activation were developed. The model was run as a one -
compartment model representing the area of the open atrium space. A fire was placed in
the center of room at the floor level. The fire was assumed to be a growing fire based on t-
squared assumption. For this project the fire was assumed to grow at a moderate rate,
which Gage -Babcock feels is appropriate given the occupancy, fuel loading, typical fuel
spacing, and natural time delays that occur when a initial burning item spreads to adjacent
items with any separation distance. Sprinklers were assumed at the atrium ceiling with
spacing representative of the furthest away a sprinkler could be based on the proposed
atrium ceiling design. The sprinklers were assumed to- be quick response; intermediate
temperature sprinklers.
The input file for the model follows with a printout of the spreadsheet output from the
model. The model shows predicts that the sprinkler will activate at 508 seconds after
ignition, which corresponded to a fire size of 2,870 BTU/s. The design fire used for this
analysis is a steady state fire of 5,000 BTU/% which provides a very conservative design
basis based on the results of the model.

Salconu SRni11 Plume:
The design fire for the balcony spill plume was arrived at using the Sprinkler effective
assumption allowed by CBC 905.6.2.4. Using a subroutine of the computer model
FPETooI predictions for sprinkler activation were developed. The model was run using
quick response, ordinary temperature sprinklers with a 10 ft. ceiling and spacing from the
fire to the sprinkler of 10 ft. The fire was assumed to be a growing fire based on t-squared
assumption. For this project the fire was assumed to grow at a moderate rate.
The model shows predicts that the sprinkler will activate at 237 seconds after ignition,
which corresponded to a fire. size of approximately 618 BTU/s. Based on this result the
design fire for balcony spill plume used for this analysis is a steady state fire of 625 BTU/s.

FOR COWSTRUCTICI�
DA7E1`��8Y d
Wlndow lame:
To determine if a window plume is an applicable scenario far this project fire modeling was
done to determine If a window would break when exposed to a fire in a guest room_ Using
the computer model CFAST Version 3.1.7, a one -compartment model representing the
front room of a typical gust suite.was entered. A fine was placed in comer of the 13 ft. by
15 ft. room and a quick response, ordinary temperature sprinkler was placed at the
midpoint of the wall away from the fire (sidewali sprinklers are proposed in guest rooms).
The fine was assumed to be a moderate t-squared fire that stops growing and remains
steady at sprinkler activation, which the model predicted at approximately 105 seconds or a
fire size of 134 BTU/s. The ceiling height used was 8 ft. 6 inches.
The input file for the model follows with a printout of the spreadsheet output from the,
model. The upper layer temperature form the fire was recorded and compared to the
standard time -temperature curve used for testing of windows. The model predicts that the
temperature the window would be exposed to Is well below the exposure required to pass
the testing required to obtain a fire rating. Therefore, it is assumed that the window will not
break and a window plume does not need to be used in the smoke control design on this
project.
