FOREWORD
The U. S. Environmental Protection Agency is charged by Congress with pro-
tecting the Nation's land, air, and water resources. Under a mandate of national
environmental laws, the Agency strives to formulate and implement actions lead-
ing to a compatible balance between human activities and the ability of natural
systems to support and nurture life. To meet this mandate, EPA's research
program is providing data and technical support for solving environmental pro-
blems today and building a science knowledge base necessary to manage our eco-
logical resources wisely, understand how pollutants affect our health, and pre-
vent or reduce environmental risks in the future.
The National Risk Management Research Laboratory is the Agency's center for
investigation of technological and management approaches for reducing risks
from threats to human health and the environment. The focus of the Laboratory's
research program is on methods for the prevention and control of pollution to air,
land, water, and subsurface resources; protection of water quality in public water
systems; remediation of contaminated sites and groundwater; and prevention and
control of indoor air pollution. The goal of this research effort is to catalyze
development and implementation of innovative, cost-effective environmental
technologies; develop scientific and engineering information needed by EPA to
support regulatory and policy decisions; and provide technical support and infor-
mation transfer to ensure effective implementation of environmental regulations
and strategies.
This publication has been produced as part of the Laboratory's strategic long-
term research plan. It is published and made available by EPA's Office of Re-
search and Development to assist the user community and to link researchers
with their clients.

ABSTRACT
The purpose of this study was to develop radon diagnostic procedures and mitigation strategies
applicable to a variety of large non-residential buildings commonly found in the State of Florida.
The investigations document and evaluate the nature of radon occurrence and entry mechanisms for
radon, the effects of heating, ventilating, and air-conditioning (HVAC) systems configuration and
operation on radon entry and dilution, and the significance of occupancy patterns, building height,
and other building construction features. A primary focus of this project was the effect of the HVAC
systems of a large building in influencing the transport, entry, and hopefully the minimization of
indoor radon in the building. Two buildings were investigated, both of which showed an inverse
relationship between dedicated ventilation air and indoor radon concentrations, as was expected.
Both also showed signs of aberrant HVAC design, operation, and maintenance that presumably
adversely affected indoor radon and other indoor air quality variables. The second building showed
clear indications of foundation design elements that contributed to radon entry. Some
recommendations relevant to building standards can be concluded from this project. First, design
and construction should concentrate on elimination of major soil gas pathways such as hollow walls
and unsealed utility penetrations. Second, HVAC system design should include strategies designed
to minimize depressurized zones adjacent to the soil. Third, while increased supply ventilation is
generally helpful for radon control, it is clearly not the most cost-effective solution or prevention tool
once the requirements of occupant comfort and general indoor air quality have been met.

Deerfield Beach, FL.
BUILDING DESCRIPTION
The building is a combination office and warehouse/maintenance facility of approximately
46,000 gross square feet in size.
The office space portion of the building consists of two wings constructed to form an L
shape. The north wing is 3 floors and
each of these floors measures approximately 5600 gross square feet (112'x 50'). The east
wing is also 3 floors and each of these is approximately 6200 gross square feet (124'x 50).
The warehouse/maintenance portion of the building is located in the crook of the L shape. It
is predominantly a high-bay 2 story space provided with 8 - 10'x 12' metal overhead doors
for easy vehicular access. The warehouse area is primarily used by a maintenance crew that
services an adjacent apartment complex. The warehouse/maintenance area measures
approximately 10,450 gross square feet (110'x 95').
The building was designed and constructed in the 1987/88 timeframe.
ARCHITECTURAL FEATURES
The building is constructed as slab-on-grade. The slab is 6" reinforced concrete on local fill.
The entire building slab is provided with a 6 mil polyethylene vapor barrier.
The exterior walls are 8" precast masonry units with painted stucco finish.
The exterior doors and windows are hollow aluminum frame storefront style. All exterior
windows are operable.
The roof is a 20 year built-up roof. It consists of 4 ply tar and gravel insulated with 2" of
rigid board insulation on bitumen.

MECHANTCAL FEATURES
The entire amount of occupied office space is provided with heating, cooling, and ventilation
(outdoor air) from 22 separate HVAC systems.
Each of the 22 systems is a split DX system. 18 of the air handling units (AHU) serve the
office space and are horizontally mounted above the hung ceiling of the space each serves.
The 3 AHU's that serve the elevator lobbies are located in equipment rooms. 1 AHU is
located in the warehouse/maintenance area and serves a small office space.
All AHU's serve their space through a system of distribution ductwork.
All condensing units are frame mounted on the roof.
All AHU's are provided with electric resistance heating elements.
Building exhaust is provided by 3 roof mounted exhaust fans. The 3 exhaust fans serve the
north wing, the east wing, and the elevator lobbies. Naturally, exhaust is realized from the
toilet areas on each floor.
The heating and cooling capacities of each system range in size from 2.91 tons cooling/7.2
kw heating to 9.16 tons cooling/15 kw heating.
The original design of the mechanical HVAC systems called for the installation of a gravity
fed outside air system. It consisted of 3 outside air duct risers (OAR's). Each of these
OAR's would take outside air from the roof level and supply it to the return air ductwork of
each individual AHU.
The OAR's were designed to provide a total of 4600 cfm of outside air (10% of the total
supply air).
The original building air balance as designed for the office space was:
supply air exhaust air outside air
North wing
18,300 cfm 680 cfm 1830 cfm
East wing
18,000 cfm 520 cfm 1800 cfm
Elev. lobbies 8,700 cfm 1110 cfm 870 cfm
Total
45,000 cfm 2310 cfm 4500 cfm

HVAC MODIFICATIONS
In April of last year, Bailey Engineering Corporation (BEC) measured the total outside air
coming into the building at 963 cfm. This represents only 21.4% of the 4500 cfm called for
in the original design (see previous table).
Although this low number appears to meet the GSA lease requirements of 5 cfm per person,
however it may not meet ASHRAE Standard 62-1989 requirements of 15 cfm per person.
The bigger problem is that this low quantity of outside air is not enough to maintain a
positive pressure in the building (assuming the exhaust air systems are operating properly).
To compound the imbalance, BEC found that at least 50% of the AHU's were
thermostatically operating in the "auto" mode, which3 means that when the indoor
temperature is satisfied, the AHU is shut down. When the AHU shuts down, no outside air
can be introduced to the space.
At that time BEC recommended a number of HVAC system improvements to the building
owner one of which was that the gravity fed feature of the OAR's be replaced with forced air
supply fans. See the June 21, 1991 report by BEC for other recommendations.
Subsequently 2 new supply fans were installed on the OAR's and in February of this year
BEC measured a total of 2981 cfm being supplied to the AHU's on a continuous basis. This
is still only 66.2% of the original design but is substantially higher than the lease
requirements of 5 cfm per person. Accordingly, using the ASHRAE standard of 15 cfm per
person, the OAR's can handle a building occupancy of 198 people while still maintaining a
positive building pressure.
The conditions stated above were in place at the time of our present study.

Dear Susan,
Attached please find performance tests for the outside air intake
fans.
Please note the following items are effecting the performance of the
fans.
1. The air conditioning unit which serves the north west corner
©n the second floor vas in the fan "auto" position, not in
the fan MonM position. Therefore, the fan only ran when the
thermostat called for cooling.
2. The air conditioning units which serve the first floor, with
the exception of the unit over the maintenance supervisors
office, were also in the fan "auto" position.
3. The belt is loose on the supply fan, which serves the south
east wing, which is effecting fan performance.
In addition, the following conditions were noted:
l. The pitot tubes were disturbed to a position which would
cause them to read inaccurately. The velocity portion of
the tube was not parallel to the air afcreaa and was leaning
backwards.
We remedied this situation by modifying the mounting using a
styrofoam cup to give the tube two points of support. In
addition, we secured the tubing with tape so that the tubing
did not put a strain on the pitot tube and it remained in an
upright position.
U. The holes drilled in the slab were found not to go
completely through the slab by Susan. A longer drill was
curchased and Don Pennington, of our office, drilled the
iength of the drill (12w) in the conference room location

without getting through the slab. It was thought tnat there
may be a footing in this location, so he moved west 12M end
redrilled. After drilling 4", soft brown sand was
®nrnnnt-*riM. Thc» fnhi» was p"l*np/1 in thf* nfiv hrtl* «nr!
sealed. The hole in the copy room was drilled another 2"
before medium brown sand was encountered. The tube was
replaced and sealed.
The hole in the maintenance directors office was drilled
another 3M before medium brown sand was •ncountarad. In
aLtenptin«| to plaoc -tho probo back in hole, it was found
that the drill had defected due to a piece of rebar and the
tube was placed back in the hole and sealed.
o. J* v&a *1 n&te* that a&tht ei tha vLre. running £re» the
pressure switch was run across the back of fluorcsoant light
fixtures. It has been our experience in the past that, due
to magnetic resonance in the balast of the light, that
erroneous signals are often transmitted even using shielded
cable. This cable is not shielded. Where it was obvious, I
moved the wire away from the top of the light fixture.
4. It was noted that a portion of the ceiling on the third
floor was sagging badly. Inspection revealed several pieces
or drywiii h»<* lt above the cailiner. th«se were
removed, the grid straightened, and the tile replaced.
5. The supply fans were shut off and polyethylene was wrapped
around each intake. This was accomplished around 2:30 p.m..
NOTE - Velocity probes may show some velocity or static
pressure in the outdoor air intake system. This in
normal transfer of air from unit to unit, depending
on which unit, would have the higher static draw.
Inner zonal (floor to floor) transfer may be
accentuated.
6. We aided Susan in placing out all of the cats and left Susan
at the site at 5:15 p.m.
7. We will return to the site Monday for the next scenario'of
setting the fans at approximately 5 cfm/person, based on
ASHRAE Recommendations.

JOB NO.: 91-135
Dear Susan,
On July 6, 1992 v* vent, to the site to set up the third performance
criteria for the building. Our effort was directed at reducing the
outside air intake to 5 cfra per person, which is the cfm required by
the largest tenants' lease. The following items and conditions were
noted:
1. Upon arriving at the site, it was found that several of the
air conditioning units in the first and third floors had the
fane in the "auto" position in the east wing. In the north
• wing, all the fans in the first floor were found to have
¦their fans in the "auto" position, on the second floor, one
unit had a fan in the "auto" position. On the third floor,
the very north unit had its fan in the "auto" position. All
fans were set to the "on" position before attempting to
balance the system.
2. The belt on the supply for the south east wing was
tightened.
3. We shut down the outside air intake fan and found that
quantities to the third and second flyuru wcro abova tha
i. eruju ij. c J ai.tvui'ii* isA t.hA quafea the fi*3t floor vao not
sufficient. Aft*? c ocrico of tcoto, it uac dotarmined that
it was necessary to run the fan in order to aohieva tha
desired level of air entering the building and to assure a
positive flow in the outside air intake ducts. Baffles were
installed inside the fan across the filter banks to reduce
the effective area and raise the static pressure inside the
fan housing. After several tests, we were able to get the
correct total air flow from the fan.
4. It took a lot longer to balance the fans to the 5 cfn'.s per
person and since it was approaching three o'clock, I read
the total air flow on the fans by reading the ducts serving

the third floor and the duct which serves the first and
second floor coming from the third floor fan. The effort
was then directed to helping Susan place the cats and
to reattach all the tubes to the equipment in order to be
able to leave the site at the time required by the tenant.
5. It was noted that one area of the third floor, north wing
6outh corner, was particularly warm upon checking the air
conditioning units, it was noted that the condensing units
were not producing any cooling. It was also noted that
there was a third unit serving this north third floor, space,
which had a knocking sound coming from the compressor.
Maintenance was contacted and they checked the units. It
was found that the two units were out of freon gas and that
the third unit was not refrigerating. This will effect the
temperature and humidity reading, which were taken on the
third floor.
It should be noted that when dealing with air quantities that are
this low (5 cfm per person) in ducts of this site, we have found
that slight variation in internal and extArnal conditions can shift
the results significantly.
It appears that the amount of tampering with the thermostats is
significant even with locking covers. I put the covers back on the
thermostats in the first floor east space.
We left the site at 5:30 p.m. and will return on July 14 to run the
next set-up condition.
Should you have any further questions, please contact our office.

Dear Susan,
Attached please find the July 14, 1992 performance tests for the
outside air intake fans. This is based on attempting to place the
maximum cfm into the building. Please note the following conditions
that affected the performance of the fans:
1. In reading the supply air intake quantities, we found that
they were significantly shifted from the prior eet-up
condition, and in checking.the fans, we found that several
'fans vere in the "auto" position. The third floor, south
east wing, had two fans in the "auto" position. The third
floor, north wing, had three fan6 in the "auto" position.
The second floor, north wing, had the fans in the "auto"
position. The first floor, north wing, had the fans in the
"auto" position. The thermostats in the first floor, south
east wing, had all the covers removed, however, the fans
vere in the "on" position. Other thermostats checked in the
second floor, south east wing, had the fans in the "on"
position, however, it: was found that the supply air vas
bypassing the second floor and going directly to the first
floor. In reviewing our notes from the initial testing that
we did on the building last year, this condition happened
then. Apparently the air runs past the tap, it is not
distributed to the second floor. The path of least
resistance is for the air to go to the first floor as there
is a lack of sufficient static pressure in the ductwork to
direct it into the second floor duct,
2. It was noted that two of the condensing units that supply
the third floor, one marked Unit 300 and the other marked
Unit 3-2 vere not providing proper refrigeration. The unit
marked 3 00 was iced up, vhich typically is an indication of
low refrigerant charge.

3. The supply fans were set at their maximum capability. It
should be noted that we did adjust the damper in the third
floor space in order to store evenly distribute the air to
the lower floors. The movement in the dampers of the third
floor space did not reduce the total air flow from the fan3.
4. It was noted that the supply fans serving the south east
side is still low on cfm, even though the belt has been
tightened. Measuring the pulley's indicates that the
pulley's had not been changed as requested by us to
maintenance in the orginal set-up last year. We assume that
the pulley could be changed on this fan to increase the
output. The fan iB presently at its maximum cfm under its
present operating conditions.
*LEASE NOTE:
Review of the data from the intial set-up of the building and this
tasting indicates that the air flove total to the building are not
significantly different under what ve are terming as maximum air
flow.
Ve left the site at approximately 1:30 pm.

Fan SF-1 and SF-2
Both fans fall short of the specified CFM. A review of the
installed equipment against the specified shows that the
installed equipment requires more horsepower to do the same
job than was required by the specified fan. We recommend
that you purchase an adjustable drive pulley for each fan and
adjust the pulley until the motor reaches 120% of its full
load amps (l.l amps). Below is listed the operating
characteristics of each fan. Should the motors fail in t:h'»
future, they should be replaced with a 3/4 HP motor.

We suggest you start with a 6" adjustable pulley. This
should give you 2000 CFM on each unit. However, this may
overload the motor. They must check the motor amps when
making this change. Adjust the pulley to maximum amperage.
As to the air flow, the airflow for each floor should
increase proportionally and there should be no need to
recheck the sums.

Summary
The present air quantities delivered to each floor are
substantially above the required 5 CFM per person, stated in
the lease document. During the time we 'were on each of the
floors, the peak occupancy has been 17 people in any one
area.
There was a thermostat that was loose on the wall, on the
second floor, north side, center unit. This can cause the
thermostat to be extremely inaccurate. This thermostat
should be secured and calibrated.
Should you have any further questions, please contact our
office.

RE: Ventilation Evaluation
Financial Center North
300 Lock Road
Deerfield Beach, Florida
ATTN: Mr. Thomas L. Anderson, CPM
Dear Mr. Anderson,
As a result of our preliminary evaluation of the ventilation
systems conducted April 25, 1991, Bailey Engineering
Corporation was authorized to conduct additional testing and
balancing to provide adequate ventilation are to all occupied
spaces.
The purpose of this test was to determine the actual volumes
of ventilation air being introduced into the systems. If the
total volume met or exceeded the design values, each air
handler was to be balanced to its proper volume of outside
air.
Should the volume of outside air prove to be less than the
required CFM, additional engineering would be necessary
< to design the modifications to the systems that would satisfy
•the ventilation requirements.
The additional testing and balancing was conducted June 4,
1991 by Ron Bailey and Don Pennington. Test measurements
were taken of the total volume of outside air at each of the
two outside air ducts as they enter the building at the third
floor. The branch ducts that provide outside air to the
third floor units were then tested and the air volumes
recorded.
Prior to testing, all thermostats were indexed to constant
fan operation. It was observed that more than 50% of the
units were set to operate the fan in the AUTO position. Less
than 50% of the units were calling for cooling which weans
that less than half of the air handlers were in a condition
to induce any outside air at all.
Our preliminary report recommended that all units be operated
with the fan in the "ON" position.

It was also observed that the outside air duct connection
between the attic and the intake hood was not sealed. It was
possible that a portion of the measured outside air flow in
the outside air duct could be attic air that had been induced
into the duct as a result of the negative operating
pressure at that point of the systems. This means that the
measured outside air volume could be partly recirculated room
air and not totally outside air. This would further
contribute to poor indoor air quality.
TEST RESULTS
AREA TESTED ACTUAL CFM DESIGN CFH
North wing Total 496 2250
3rd. Fl. North 285 750
South Wing Total 467 2250
3rd. Fl. South 242 750
Total ventilation air being supplied to the building is 963
CFM. The tested total volume of outside air appears to meet
the requirements outlined in your GSA lease form requiring 5
CFM p£r person occupancy. The actual tested volumes would be
sufficient for 192 people. This appears to be more than the
actual occupancy of the building. Technically it appears
that you meet the strict interpretation of the conditions of
the lease.
Because the total volume of measured outside air was less
than the ASHRAE standard for minimum ventilation, no
additional attempts were made to balance the outside air
between the individual floors.
*
Total measured CFM of outside air is only 21% of the volume
called for in the original design. These low levels of
ventilation do create other problems:
1. The actual ventilation volumes do not approach the
current ASHRAE standards and .. codes. Minimum
ventilation standards call for 15 CFM per person of
outside air.
2. According to ASHRAE standards, the current volume of
ventilation may not provide acceptable levels of
indoor air quality. The internal contaminates
attributable to people census and outgassing of
building material, carpets, and furnishing cannot be
adequately diluted with the current volume of outside
air provided.

3. The low volume of outside air is not sufficient to
offset the volume of exhaust air. This will create a
negative pressure vithin the building resulting in
uncontrolled and untreated infiltration. This may
also contribute to poor indoor air quality and
uncontrolled humidity.
ADDITIONAL ENGINEERING REQUIRED
The HVAC systems as currently installed and opernted are not
capable of inducing sufficient volumes of outside air into
the building to satisfy minimum standards for ventilation.
Modifications must be made before the systems can perform as
required.
The modifications should consist of the following basic
components:
1. The existing gravity intake hoods are to be removed.
Koof curbs to support the nev; supply fans are to be
properly attached to the roof.
2. New fan powered supply fans are to be installed on the
new roof curbs and securely connected to the existing
outside air ducts.
3. Motor operated dampers, are to be installed in the
existing outside air ducts to close when the supply
fans are not in operation to prevent uncontrolled
outside air from entering the systems during
unoccupied hours.
4. Power wiring for the new supply fans can be supplied
by extending existing convenience outlet locations on
the roof.
5. The new supply fans are to be controlled by time
clocks to operate only during occupied hours. The
existing exhaust fans are to be controlled by the same
time clocks on the same schedule.
6. Wire the air handling unit fan subbase to run
continually. Install a new time clock.
After the installation of the necessary modifications is
complete, Bailey Engineering Corporation will test and
balance the volume of outside air delivered to each air
handler to conform to ventilation standards.

Dear Ton,
This will confirm our telephone conversation recommending the
sequence of steps required to provide acceptable ventilation
standards as outlined in our report dated May 4, 1991.
We recommend that three basic phases be implemented and
completed:
I. PRELIMINARY TESTING
Each system air handler should be tested to determine
the following: /
-) Total air flow in CFM
-) Return air flow in CFM
-) Fresh air volume in CFM
Careful evaluation of not only CFM air flow, but
direction of flow as well, is required to insure
measurements are accurately defining volume as well
as type of air in the system. It is possible that
flow in F/A ducts way in part be circulated return
.air from another inter-connected system.
II. ENGINEERING OF SYSTEM MODIFICATIONS
Design criteria will be determined from the results
o): the prt.liiiiinary testing performed under I'hai-.e T.
Based on our initial evaluation and report, we feel
the following items must be addressed:
1. Fresh air fan selection and design of
application.
2. Automated dampers and actuators.
3. Control system to interlock all system
components for balanced ventilation.
III. FINAL TESTING AND BALANCING
After the modifications are complete, a final Test
and Balance mast be performed to insure the proper
ventilation standards are maintained and the control
strategies are functioning as designed.

Our fees for professional and technical services to complete
the above described phases of the project are:
Phase I Preliminary Tests $2500 + $500
Phase II Engineering $2200.00
Phase III Final Test & Balance $3500 + $500
It is possible to eliminate Phase I and proceed directly with
the engineering design work and the final Testing and
Balancing. That vill insure that ventilation standards are
maintained under all operating and occupancy conditions.
This approach does, however, assure that there is a
ventilation deficiency that cannot be corrected by balancing
or altering methods of operation.
We at Bailey Engineering Corporation will be pleased to
provide all of the Professional and Technical services
necessary to satisfy the project requirement.
Please advise us how you wish for us to proceed.

Deerfield Beach, Florida
Attention: Mr. Thomas L. Anderson, CPM
Dear Mr. Anderson;
Bailey Engineering Corporation was engaged to evaluate the existing
HVAC systems at the above location. The purpose of the evaluation
was as follows:
1. Compare the original design criteria to current standards
for ventilation requirements.
\
?. Determine if the systems conformed to the design drawings
and specifications.
3. Evaluate the actual performance against the design and
current requirements of ventilation as related to indoor air
quality.
METHODS OF THE EVALUATION
Several steps were taken during the course of the evaluation. The
basic procedures included:
1. Plan review to determine the original design criteria
including equipment size, total air quantities for each system
in CFM, fresh air quantities in CFM and percentage, system
static pressures, equipment location and duct system design.
2. Physical examination of the systems to determine if the
actual installation conformed to the design criteria.

The plans call for a total of 22 split system A/C units. There are
7 systems on each occupied floor with an additional unit for the
small office located in the warehouse area. Total design fresh air
quantities are 1500 CFM per floor or 4500 CFM total for the
occupied office areas excluding the warehouse office. This
represents 10% of the total circulated air flow.
Exhaust fans remove a total of 2310 CFM of air from the building
through toilet exhaust and from meter and electrical rooms. This is
approximately 50% of 'the designed fresh air and should result in a
desired positive pressure within the building if all systems are
balance to the design criteria.
Most of the air handlers are horizontal configured and installed
above the dropped ceiling space. There are two common fresh air
intakes located on the roof. Each intake serves the air handlers
installed in the respective wings of the building, Northwest or
Southeast. A main fresh air duct extends from the fresh air intake
into the building and branches at each floor with smaller branch
ducts connected to the return air duct of each air handler.
Balancing dampers are specified at each air handler fresh air duct.
BITE EXAMINATION AND TECHNICAL REVIEW
It appears that the actual installation of the HVAC systems closely
follows the original design criteria. The sequence in which the
information in this section of the report is presented has no
significance on the importance of the information. The following
conditions were observed during the evaluation:
1. Most of the system room thermostats were being operated
with the Fan Switch in the "AUTO" position. This means that
when the unit cycles off when the temperature is satisfied,
the air handler fan cycles off as well. There can be no
introduciton of Fresh Air into the system when the fan is not
in operation.
2. Less than 1/3 of the systems were observed to be operating
during this evaluation. It was not known if the equipment was
off because the thermostat was satisfied or if there were
operational problems. Judging from the observed space
temperatures in the various zones, it is believed that the
space thermostats were satisfied.
11-37

3. The specified dampers in the fresh air ducts were installed
and, except for a few, were all in the open position.
4. The design quantities of fresh air appear to be more than
is sufficient to satisfy current ASHRAE standards for
ventilation and indoor air quality. In a non-smoking
environment, the specified fresh air volumes would be
sufficient for a census of 100 people per floor of the
building. At no time did we observe that density of occupancy.
5. All equipment of the HVAC system is allowed to operate 24
hours per day including air handlers, A/C units and exhaust
fans.
CONCLUSIONS
The conclusions of this report are based on our review of the
original plans, observation of the HVAC systems as they are
currently installed and operating, and applying standard
engineering principles to the available data.
If it is assumed that the systems are balanced and are capable of
inducing fresh air and exhausting building air in the quantities
that are specified by the original design, the current method of
operating the fan in the "AUTO" position will not allow the system
to function as designed. If an air handler fan is "OFF", there can
be no fresh air induced into that portion of the system.
Our observation of approximately 1/3 of the systems "OFF" would
mean that even if balance properly, the systems are inducing only
1/3 or 1500 CFM of fresh air into the building. The 2310 CFH of
exhaust air would then create a negative pressure within the
building. This would create untreated and unfiltered infiltration
into the space with any associated humidity and contaminates.
without performing a complete test and balance of all components of
the HVAC system, it is not possible to determine how closely the
systems are performing to the original design parameters.
The exhaust systems may very well be exhausting more air than was
designed. It is also very unlikely that the low static pressure
produced in the return air plenum of the air handlers is capable of
overcoming the static resistance of the fresh air duct system. This
would result in less fresh air being induced into the systems that
was designed. This would be especially true for the first floor air
handlers that are the most remote from the roof intake opening.

RECOMMENDATIONS
There are several immediate steps to be taken to insure the HVAC
systems are performing at levels to meet current requirements for
ventilation and indoor air quality.
1. Operate all systems with the air handler fan in the "ON"
position to insure constant air circulation and induction of
fresh air.
2. Perform a test and balance of each system component to
verify design requirements are met.
3. If the systems as installed and operated are not capable of
inducing the required quantities of fresh air, fans may be
required on each of the fresh air duct systems to provide the
required volumes.
4. Install time' clocks on the exhaust fans to prevent
unnecessary ventilation during the unoccupied hours.
5. Install motorized dampers on the fresh air intakes operated
on the same occupied schedule as the exhaust fans. This will
prevent not only unnecessary ventilation when the building is
unoccupied, but stabilize the building and prevent negative
pressure. This will eliminate the introduction of infiltration
and its associated contaminates.
6. An additional energy saving strategy would be to place all
" A/C systems on a time clock schedule to prevent after hours
operation.
7. Provide Bailey Engineering with a copy of the past 24
months energy history from FPL to determine the level of
energy savings potential.
Bailey Engineering will be pleased to provide the necessary
professional and technical service to design the required
modifications and to monitor the project to insure proper
application and results.

Period 1 for one day starting June 17, 1992, was for 5 zones on the first floor which had
an overall ACH of 0.47 ± 0.04 h"l. As expected, the zonal condition numbers are high for
zones 1, 2, and 3, implying those three (3) zones are best treated as a single well-mixed
zone. Note the large uncertainties on their exfiltration, infiltration, and zone-to-zone
rates. Also note that those zones which are not physically adjacent indeed do have very
low zone-to-zone rates.
The next sheet is a recomputation of period 1 but with zones 1 and 3 combined. Now
a pattern is apparent. Air infiltrates into the combined zone (322 ± 124 m^/h) but little
exfiltrates (-5 ± 180). The new zone 1 air moves to zone 2 where it exfiltrates (little air
infiltration). The net first floor air flow pattern is air infiltration into the first floor east
zone (AHV1-567) with 3/4 exfiltrated and 1/4 transferred to the first floor lobby where
most of the excess is exfiltrated but a small amount also flows to the new zone 1. Since
zone 1 air flows to AHV1-2 (zone 2), zone 2 probably has the lowest first floor building
pressure back to AHV1-567 with the highest.
Period 2 (6/18 - 7/1/92) had the problem with the 51 (ptPDCH) source being ruptured;
note the high concentration (67.6 pL/L) on CATS 8618 which was near the ruptured source.
The ruptured source caused the 5-zone results to be irrational (large negative flows and
larger uncertainties). Note that the concentrations of the CATS deployed in the non-PFT-
tagged zones 6 to 9 are displayed but deleted from the computations of flow rates.
The second sheet was computed combining zones 3 and 4, using the zone 4 tracer
(PMCP). Now the overall ACH is 0.52 ± 0.05 h^ and the zonal condition numbers are all
near unity, indicating a very successful test The four zones are nearly isolated from each

other; also the third floor CATS showed little tracer except in the lobby, probably via the
elevator shaft The only significant air exchange was between zone 1 and the lobbies and
the lobbies with the first and second floors east.
Periods 3 through 6 were also performed with the same setup as in Period 2. Some
general comments: 1) some of the volumes written on the data sheets were different; we
will settle on 1132 m3 for zones 1 and 2,204 for the lobbies, and 945 m^ for zone 5 unless
we hear differently; 2) some CATS had no tracer and were deleted from the flow
calculations (presumably they were controls). Note that on 4 through 6 the wrong
volumes were used; that only affects the ACH values, not flow rates.
As shown in Table 1, Periods 3 and 4 were performed under lower ACH conditions
than Periods 5 and 6 (which were similar to Periods 1 and 2 also). Was the low ACH
during Period 3, the fourth of July weekend, due to the air handling systems being off?
The infiltration rate into zone 1 (0-1) increased almost 4-fold from low ACH (- 100 m^/h)
to high ACH (- 300 to 400 m^/h) conditions; the infiltration rates into the other zones did
not show the same consistent trend with total ACH change.
The overall air flow patterns were as follows: outside air infiltration into zone 1
(equal to or one-half that into zone 2) and into zone 2, a net flow from 2 to 1, followed by
exfiltration from zones 1 and 2; there was also a strong flow from zone 4 (first floor lobby)
to zone 1 (first floor north wing). Thus, the high flow rates from the outside and above
and adjacent zones into zone 1 coupled with the high exfiltration rate from zone 1 would
imply that a modest negative air pressure (relative to outside) existed in zone 1, especially
during high ACH periods. This would maximize radon penetration into zone 1 from soil
gas-
In most cases there was high infiltration into zone 5 (the first floor east wing) with
lower exfiltration, net air flow from zone 5 to zone 4 (first floor lobby), and net air flow
from zone 4 to zone 1. This again implies that zone 1 had a lower air pressure than zone 4
which was also lower than zone 5.
The impact of these building flow patterns (i.e., pressures) on radon penetration from
soil gas infiltration is such that zone 1 should have the highest radon source strengths
(from Period 1 it would appear that AHV1-2 had the lowest pressure in zone 1 compared to
AHV1-1 and AHV1-3, and thus should have the highest radon source strength), zone 4
lower, and zone 5 the least Also, of course, zones 3 and 4 (second floor zones) should
have zero radon source strengths.
As I mentioned to Charles, if you provide us with the radon concentration data (that
is, your best estimates of the average concentrations and their standard deviations for each
of the five zones, averaged over the same time as the PFT measurement), we will compute
the average source strengths in each zone and their uncertainties for as many of the
periods as you have radon data.

Attached is an example of how we are using this procedure in the determination of
PCB and dioxin source strengths in a building from a transformer fire. We would be
pleased to compute the radon source strength data for you at no charge provided we may
use the data (along with other similar data) in a paper we are planning on source rate
determinations.
I look forward to collaborating with you on the radon source rate determinations. Let
me know if you have any questions on the results.

General Description of Che BNL/AIMS Output format
June 1986
Revised: December 28, 1988
The cop portion of the BNL/AIMS sheet shows Che project title, the bouse
name, the start and stop times and dates for sampling, the date analyzed, and che
final time and date chat computations were made. The first four digits of Che BNL
Code represent the disk file number; the letter, the house position (e.g., "D"
means fourth house in the file); the last, the number of zone reductions (e.g.,
0( 1, 2, etc.).
The rates section gives the overall infilcration rate (m^/h) for all zones
and the air change rate (h~l) by dividing by the total volume. Next is given, for
each zone, the zone location, source information (gravimetric calibration rate at
25°C, quantity, and total emission rate adjusted for temperature, assuming an *
enthalpy of 6.8 kcal/mole), and exfiltration and infiltration rates with their
standard deviations (SDs), followed by the zone to zone air flow rates and SDs.
The total flow In or out of each zone, sometimes a useful quantity, is also given.
Note: All gaseous volumes, i.e., those for air flow rates and perfluoro-
carbon tracer (PFT) source rates, are reported at conditions of 25°C and 1 atm.
When comparing results with those from other techniques, consideration must be
given to the conditions under which those results are being reported. For
example, tracer decay volumetric rates are reported for the conditions at the site
(i.e., che Indoor temperature and the prevailing barometric pressure).
The analysis section gives for each zone the volume, source type, and average
tracer concentration with SDs, only for those used in the computations. Below is
the Individual CATS analyses by zone with the calibration correction factors. The
PFT concentrations of those used in the computations are reported first, by zone,
and then those for other PFTs found. Note that even though separate calibration
curves are used for the mt-, mc-, and total's PDCH, the sum of mt and mc is
generally very close to the m PDCH.
The notes section mentions the SDs assigned to the source rates and volumes;
conditions or results that should not exist are flagged by printing in capital
letters. If the overall normalized condition number is greater than 2, then the
two zones with the highest zone condition numbers are merged and the calculations
repeated until the above condition number is less than 2.
The current number codes of the tracers are:

Although there are 7 PFT source types currently available, chromatographic
analysis limitations restrict certain combinations. In addition, the software is
not yet available for the computation of more than 5 zones.

APPENDIX IV
Polk Life & Learning Center Initial Engineering Report
IV-1
-------
Polk Life & Learning Center
Bartow, FL.
This site consists of three buildings operated by the Polk County School Board: The Center
for the Trainable Mentally Handicapped, the Severely Handicapped Center (two classroom
addition), and the Greenhouse. The Center for the Trainable Mentally Handicapped and the
Greenhouse were designed in 1974 and built in 1975. The Severely Handicapped Center was
designed in 1984 and constructed in 1985. This engineering analysis focuses primarily on
the Center for the Trainable Mentally Handicapped.
BUTLDING DESCRIPTION
The Center for the Trainable Mentally Handicapped is a single story training/school building
of approximately 18,000 gross square feet in size.
Architecturally, the building is constructed as a slab-on-grade.
The slab is 4" reinforced concrete on compressed fill. "Die slab is provided with a vapor
barrier. Presumably the vapor barrier is polyethylene (the drawings are not specific).
The walls of the Center are 8" CMU with stucco exterior and 5/8" gypsum board on l"x 2"
furring strips on the interior.
The roof system consists of wood truss construction with asphalt shingle roof tiles.
The interior ceilings are either lay-in tile or painted gypsum board.
All windows are either aluminum frame single hung or bay windows
Interior walls are gypsum board on wood studs.
Interior ceiling heights are 9,-0".
The Center is divided into 5 distinct fire control zones by means of rated 5/8" gypsum board
that extends to the tectum decking below the roof.
MECHANICAL SYSTEMS
The entire Center is heated and cooled by an ALL-AIR system. It is composed of a single
main air handling unit (AHU-1). The system is low pressure (2.5" wg E.S.P.) and utilizes a
single supply duct and a ceiling plenum return air system.
The individual rooms and zones are environmentally controlled by variable-air-volume
(VAV) boxes mounted above the ceiling in the return plenum. Wall mounted thermostats
control the VAV boxes.
IV-2
-------
-2-
The outdoor air is controlled by a roof mounted supply fan (F-l) that can provide up to 1200
cfm of unconditioned outdoor air directly to the AHU-1 return air plenum where it mixes
with the building return air.
The AHU-1 has the capacity to supply 5620 cfm at 57 Fdb/56 Fwb which gives the machine
a rating of approximately 21 tons. This is approximately 1.2 tons per 1000 ft2—greatly
oversized.
To heat the Center the AHU-1 is provided with a 15 kw strip heater. In addition, each VAV
box that serves a space that is on an exterior wall is provided with an additional strip heater.
VAV box strip heaters are controlled by the room wall mounted thermostat.
The Center is served by a total of 26 VAV boxes that are sized for full air conditioning load
of 11,305 cfm. The boxes are set for a minimum setting of 40% of full load. The diversity
factor is calculated to be approximately 50% for the VAV box operation. Exhaust from the
Center is by 14 exhaust fans located in the toilets, bathrooms, janitor closets, workshop, and
kitchen areas. The total building exhaust from these 14 fans is 2350 cfm.
OBSERVATIONS
It is easy to recognize that this building will always operate in an undesirable HVAC
negative pressure mode. The outdoor air quantity is 1200 cfm and the exhaust quantity is
2350 cfm. The building will be negative by 1150 cfm.
To compound this imbalance, the outdoor air fan is shut off when the return air temperature
is below 70F or above 80F. The fan controls will only allow the outdoor air fan to operate
when the return air temperature is in the range of 70 to 80F. This control feature will have
to be verified and corrected since we want to be able to introduce outdoor air in all
conditions.
This condition of no outdoor air also violates the minimum outdoor air requirements of
Chapter 6A-2 of the Florida Administrative Code, paragraph 6A-2.066 Ventilation,
subparagraph (2)a-2. Mechanical Ventilation that calls for a minimum of 5 cfm of outdoor
air per occupant at all times of occupancy.
If any building is ever to be pressurized, then the outdoor air cfm must always exceed the
exhaust air cfm.
AHU-1 will have to be checked to determine if the cooling coil can handle an increased
amount of outdoor air since it is not feasible to decrease the exhaust air quantities. The
manufacturer will have to be 'consulted on this issue.
1V-3
-------
-3-
Essentially the outdoor air quantity will have to be more than doubled for the building to
operate under positive pressure. It is also apparent that the outdoor air fan F-l will also
have to be replaced to handle the larger quantity.
OUTDOOR ATR REQUIREMENTS
According to table 2 of ASHRAE 62-1989, this facility should be served by 15 cfm per
person and that the maximum loading is 50 people per 1000 ft2. Actual occupancy is 103
students and 20 staff members.
Using ASHRAE 62-1989 and 1200 cfm of outdoor air that F-l was sized to provide-80
people can be housed. 1200 cfm is less than ASHRAE requirements based on the actual
daily occupancy plus we cannot pressurize the building.
If we reference the Chapter 6A-2 of the FAC and use 5 cfm per person-240 people can be
housed (1200 cfm/5 cfm per person). Not a realistic number and we still cannot pressurize
the building.
Doubling the outdoor air to exceed the exhaust air essentially means exceeding the ASHRAE
requirements by approximately 5 cfm per person. We need to discuss the impacts of this
step with the Polk County authorities since it appears to be the only way to attain
pressurization.
TAB SURVEY
In order to ready the Center for instrumenting, a certified HVAC test and balance firm will
have to perform the following steps:
1. Building Pre-balance Survey
a. the firm must review the design plans and become familiar with the design of
the HVAC systems.
b. the firm must visit the site and evaluate the condition of the HVAC system and
determine what components of the HVAC system are in need of replacement, repair, or
renovation in order for the system to operate as desired.
c. the firm shall develop a "punch list" of repair items for the Polk County
authorities who will provide all repairs and maintenance.
IV-4
-------
2. Building Pre-Balance Survey
a. after all repairs are corrected, the firm will visit the site to confirm that the
systems are ready for final air balancing.
3. Building Air Balancing
a. the firm shall air balance the HVAC systems as required in the final Scope of
Work (to be developed by the EPA).
It is anticipated that the Polk County will fund all "punch list" items and the EPA will fund
the TAB fee and fan replacement.

GENERAL:
All data contained in this report has been accumulated from the equipment and systems
installed on the job. All values in this report are true and correct as of the date of test and are
within the limits of field test error. All tests performed on this project meet or exceed the
standards set forth by AABC, Volume 2, National Standards.
This report indicates the initial survey conditions of the air systems serving the Polk
Life and Learning Center, Bartow, Florida. This survey was conducted to determine the
present flow conditions and equipment operation to establish a base line criteria for the
Environmental Protection Agency testing and to identify defective equipment that needs to be
repaired in order to bring the systems up to the original design capacities. This system
consists of one central air handling unit serving this building through a variable air volume
system. The unit incorporates an outside air fan to provide a constant amount of outside air
and there are individual exhaust fans throughout the building serving mostly restrooms which
are connected to the light switch and provide intermittent operation. The total air flow from
the air handling unit was determined by Pitot tube and incline monometer traverse, while the
individual outlet CFM was measured with an Alnor direct CFM measuring flow hood. This
report is organized with the air handling unit data sheet in front of the static pressure profile
and total air traverse sheet followed by air distribution sheets indicating the supply air outlet
CFM organized by box number. Following the air handling unit supply air distribution is the
exhaust air distribution. For ease of review of the deficiencies discovered during our survey,
we are listing them as follows.
1. FAN F-l
(a) The fan blade is installed backwards on the motor shaft. This is a direct drive
fan and the blade needs to be reversed in order to efficiently supply air.
(b) The motorized backdraft damper for this fan is frozen in the closed position.
We disconnect the damper linkage from the actuator and tried to manually open
this damper, however, we were unsuccessful.

2. AH-1
(a) According to the difference between the Pitot tube traverse and the summation
of the supply air outlets the duct is leaking approximately 25%. All joints at the
boxes and low pressure air distribution needs to be sealed as leakage can be felt
at these locations. The high pressure duct should be traced out and any leakage
discovered repaired.
(b) The thermostats should be checked for and properly calibrated.
(c) The box controllers inside of the variable volume boxes should be removed,
cleaned and lubricated and then reinstalled.
(d) The diversity for this air handling system is extremely large. In order to reduce
this diversity, we recommend speeding the present fan up to maximum
horsepower available with the 5 HP motor presently installed. To do this, we
recommend changing the fan drive to a Browning 2BK90H. When this drive is
changed the motor amperage should be verified to make sure that the motor is
not overloaded and if it is the variable pitch motor drive should be opened to
reduce the fan speed.
3. EXHAUST FANS
(a) Exhaust fans #4, #5, #9 &. #14 are not in operation at this time.
(b) Exhaust fan #11 is not moving any air, however, it is on. It appears that the
backdraft damper is stuck closed, not allowing airflow. We recommend that all
of the fans be removed and that the backdraft dampers and fan wheels be
cleaned.
We believe that the contents of this report, given with the above explanations in mind is
self-explanatory, however, should there be any questions or further information required,
please do not hesitate to contact our office.

GENERAL:
All data contained in this report has been accumulated from the equipment and systems
installed on the job. All values in this report are true and correct as of the date of test and are
within the limits of field test error. All tests performed on this project meet or exceed the
standards set forth by AABC, Volume 2, National Standards.
This report indicates the final balanced conditions of the heating, ventilating and air
conditioning systems serving the Polk Life and Learning Center in Bartow, Florida. The
central station air handling unit was originally designed to supply a maximum of 5,620 CFM
against a total static pressure 2.50" water column, however, our final test indicates 7,047
CFM with 1.80" water column of total static pressure. This system is a variable air volume
system and this additional flow capability should be beneficial to this type of system in times
of higher ventilation needs and should not have any negative effect considering the VAV
nature of the system.
The outdoor air quantity has been increased to 20 CFM per person per the direction of
the EPA for the purposes of their study. We have set and marked a damper in the outside air
duct at the 20 CFM per person rate, 15 CFM per person rate, 1200 CFM and 5 CFM per
person rate so that the effects of the various outdoor air quantities can be studied.
The population of this building was given at 150 people and the original design outdoor
air was 1200 CFM or, 8 CFM per occupant. Since 1200 CFM was the original design load
calculation, it follows that outdoor air flow rates above this quantity will exceed the original
design load as maximum summer conditions are approached. The original outdoor air summer
load took 1200 CFM at approximately 92.0° dry bulb/78.0° wet bulb and cooled it down to
57.0° dry bulb/56.10 wet bulb at a load of approximately 7.9 tons. At these outside air
conditions, 3000 CFM of outdoor air will require approximately 19.75 tons of air
conditioning, leaving almost no capacity for the building load.
Assuming the original design total air flow of 5620 CFM and the retum air temperature
of 84.8° dry bulb/66.80 wet bulb, with 3000 CFM of outdoor air, the maximum outdoor air
temperature capable to meet the original design mixed air temperature of 86.3° dry bulb and
69.3° wet bulb is only 88.0° dry bulb and 72.5° wet bulb. This is not to say that if these
outdoor conditions are exceeded, adverse comfort will be noticed since there are many factors
that play into the peak load. For example, at 88.0° dry bulb and 72.5° wet bulb the outside
air load is not as great and therefore the building heat gain should not be as high, allowing for
greater outdoor air load. Also, the interior load of the building may be less or a host of other
factors could influence the actual point at which comfort will be affected. The calculation
given above are only guidelines for prediction of when the total load may be affected by the
added outdoor air load.

Polk Life and Learning Center
Bartow, Florida
During the winter months at peak load of 38° outdoor air temperature and with all
boxes supplying the minimum CFM indicated in this report, the total air delivery will be only
3360 CFM. The total electric heat available is 61 KW resulting in a temperature rise of
approximately 57° (61 KW « 208,000 BTU/hour + 3360 1.08 = 57.3°). Depending
upon the building heat loss, along with internal heat gain, this may be adequate to heat the
building with 3000 CFM of outdoor air.
The box air flows indicated in this report are the maximum air flows obtained by
turning an individual thermostat to full cool with the other thermostats on the system set at
their normal operating point. The box controllers appear to be opening fully and where air
flows indicated are less than design, the air flows indicated are the maximum available under
these conditions. Minimum flow rates are non adjustable factory set and reduce the box to a
pre-set minimum position. We would like to note that box #4 &. #8 will not reduce in volume
on a call for heat and the electric strip heater on box #8 will not energize. The exhaust air
fans are direct drive fans with no speed controllers or other dampers installed in the systems
for balancing, however, these fans have intermittent operation through the light switch control
and this should not be a problem.
We would recommend utilizing the original design plans when reviewing this report for
a more thorough understanding of the systems composition and layout. We hope that the
comments made above have explained the revisions made to the outside air quantities and what
may be expected by those revisions. While these systems are not in perfect conditions and do
not match exactly the original design criteria, we do believe that the systems are providing
adequate ventilation rates for the experiment and research that is being performed. I believe
that the enclosed documentation meets with the requested scope of work, however, should
there be any questions or further information required, please do not hesitate to contact our
office.

16. ABSTRACT
The report discusses the development of radon diagnostic procedures and
mitigation strategies applicable to a variety of large non-residential buildings com-
monly found in Florida. The investigations document and evaluate the nature of radon
occurrence and entry mechanisms for radon, the effects of heating, ventilation, and
air-conditioning (HVAC) system configuration and operation on radon entry and dilu-
tion, and the significance of occupancy patterns, building height, and other building
construction features. A primary focus of the project was the effect of the HVAC
systems of a large building on the transport, entry and (hopefully) the minimization
of indoor radon in the building. Two buildings were investigated, both of which
showed an inverse relationship between dedicated ventilation air and indoor radon
concentrations, as was expected. Both also showed signs of unusual IIVAC design,
operation, and maintenance that presumably adversely affected indoor radon and
other indoor air quality (IAQ) variables. The second building showed clear indication:
of foundation design elements that contributed to radon entry. Among recommenda-
tions relevant to building standards that can be concluded from the project is that
design and construction should concentrate on elimination of major soil gas pathways
such as hollow walls and unsealed utility penetrations.
