Verification of the energy performance of the building envelope is required for all projects that require commissioning 
and verification in accordance with UFC 1-200-02; facilities that require air barrier inspection and testing are 
defined within UFC 3-101-01. As directed in UFC 1-200-02, the Commissioning requirements in this Section are based 
on ASHRAE 90.1 as required for commercial and multi-family high-rise buildings; for projects involving low-rise 
residential buildings this Section will need to be edited to meet the Commissioning requirements of IECC.  For 
commissioning requirements of Medical Treatment Facilities, refer to UFC 4-510-01 and edit this Section accordingly. 
When a project requires this Section, edit and include UFGS Section <SRF>07 27 10</SRF> BUILDING AIR BARRIER SYSTEM for additional 
performance testing and verification requirements. For projects where more oversight is needed beyond the minimum 
building envelope requirements of ASHRAE 90.1 and the requirements of Section <SRF>07 27 10</SRF> BUILDING AIR BARRIER SYSTEM, 
revise this specification accordingly. (Examples include facilities with pressurization or humidity control requirements 
such as armories, electronic equipment facilities, hospitals, and laboratories.)<BRK/>

<NPR>NOTE:  The basis for the air leakage testing within this specification is UFC 3-101-01 and the U.S. Army Corps 
of Engineers Air Leakage Test Protocol for Measuring Air Leakage in Buildings.  This protocol can be found at 
the following web site: <URL HREF="https://www.wbdg.org/FFC/ARMYCOE/usace_airleakagetestprotocol.pdf">https://www.wbdg.org/FFC/ARMYCOE/usace_airleakagetestprotocol.pdf</URL>.<BRK/>

<NPR>This specification includes additional recommendations not found in the aforementioned protocol.  These recommendations 
are based on personal pressure test experience and discussions with industry experts.  <BRK/>

An Excel spreadsheet titled Pressure Test Data Analysis, available for download at <URL HREF="https://www.wbdg.org/dod/ufgs/ufgs-forms-graphics-tables">https://www.wbdg.org/dod/ufgs/ufgs-forms-graphics-tables</URL>
, is an integral part of the building's air barrier pressure test.  Data obtained during the test may be input 
into the spreadsheet to determine the air barrier's leakage rate. <BRK/>
<BRK/>
This specification describes the responsibilities of the Contractor and the Contractor's pressure test agency.  
The building designer is responsible for creating, defining and detailing the air barrier envelope.  The Contractor's 
pressure test agency is responsible for preparing the building envelope for the pressure test, performing the 
test, recording test results, and returning the building to pre-test conditions.  The test agency is also responsible 
for performing the calculations to determine if the envelope passed the pressure test.  Diagnostic testing is 
also the responsibility of the test agency.</NPR><BRK/>
<BRK/>
<NPR>This specification does not cover duct and HVAC system pressure testing and is limited to the envelope penetrating 
dampers as deemed applicable for leakage testing.  Duct and HVAC system pressure testing references can be obtained 
from ASHRAE Handbook of Fundamentals, HVAC Design Section and Chapters and ASHRAE Standard 215, Method of Test 
to Determine Leakage of Operation HVAC Air Distribution Systems, should duct and HVAC system pressure testing 
be required by other specifications.  See Section <SRF>23 05 93</SRF>, TESTING, ADJUSTING, AND BALANCING FOR HVAC for duct 
testing requirements.</NPR><BRK/>

</SPT><SPT><TTL>DEFINITIONS</TTL><BRK/>
<BRK/>
<TXT>The definitions included here are specific to this Section.  Refer to UFGS <SRF>01 91 00.15</SRF> for definitions that apply to both Sections.  The following 
terms as they apply to this section:</TXT><BRK/>
<BRK/>
<SPT><TTL>Air Barrier Envelope</TTL><BRK/>
<BRK/>
<TXT>The surface that separates the inside air from the outside air.  The combination of air barrier assemblies and air barrier components, connected 
by air barrier accessories are designed to provide a continuous barrier to the movement of air through an environmental separator.  A single building 
may have more than one air barrier envelope.  The air barrier surface includes the top, bottom, and sides of the envelope.  The term "air barrier 
envelope" is also known as "air barrier system" or simply "air barrier".</TXT><BRK/>
<BRK/></SPT>
<SPT><TTL>Air Leakage Rate</TTL><BRK/>
<BRK/>
<TXT>A measurement of air infiltration or exfiltration through the building envelope over time.  The air leakage rate is the rate of air flow across 
the air barrier per unit surface area of the envelope at a defined differential pressure.</TXT><BRK/>
<BRK/></SPT>
<SPT><TTL>Basis of Design (BoD)</TTL><BRK/>
<BRK/>
<TXT>A document developed by the design team which includes technical concepts, assumptions, calculations, decisions, and product selections to support 
the Owner's Project Requirements (OPR).</TXT><BRK/>
<BRK/></SPT>
<SPT><TTL>Bias Pressure</TTL><BRK/>
<BRK/>
<TXT>Also known as zero flow pressure, baseline pressure, offset pressure or background pressure.  With the envelope not artificially pressurized, bias 
is the differential pressure that always exists between the envelope that has been prepared (sealed) for the pressure test and the outdoors.  Bias 
pressure is made up of two components, fixed static offset (usually due to stack effect or the HVAC system) and fluctuating pressure (usually due 
to wind or a moving elevator).  Because of pressure fluctuations many bias pressure readings are recorded and averaged for use in the calculations.</TXT><BRK/>
<BRK/></SPT>
<SPT><TTL>Blower Door</TTL><BRK/>
<BRK/>
<TXT>Commonly used term for an apparatus used to pressurize and depressurize the space within the building envelope and quantify air leakage through 
the envelope.  The blower door typically includes a door fan and an air resistant fabric or a series of hard panels that extends to cover and seal 
the door opening between the fan shroud and door frame.  The door fan is a calibrated fan capable of measuring air flow and is usually placed in 
the opening of an exterior door. With the air barrier otherwise sealed, air produced by the door fan pressurizes or de-pressurizes the envelope, 
depending on the fan's orientation.</TXT><BRK/>
<BRK/></SPT>
<SPT><TTL>Building Enclosure (or envelope)</TTL><BRK/>
<BRK/>
<TXT>The materials, components, systems, and assemblies intended to provide an environmental separator between the interior and exterior or between 
interior spaces with different environment requirements.  "Enclosure" is used interchangeably with "envelope".</TXT><BRK/>
<BRK/></SPT>
<SPT><TTL>Building Enclosure Commissioning (BECx)</TTL><BRK/>
<BRK/>
<TXT>Technical service provided on behalf of the Government to provide a quality-focused process for enhancing the performance of the building enclosure

<BRK/>
Whole building air tightness testing is required for all projects as outlined in the Editor's Note for the Part 
3 section BUILDING ENVELOPE AIR TIGHTNESS REQUIREMENT; however, this test is performed near the end of the project. 
Once the building enclosure is fully constructed, installation corrections needed to comply with the test requirements 
may require substantial disassembly and re-work. Smaller scale tests performed on mock-ups or at the initial installation 
of building components are recommended to validate the design and installation of building enclosure elements 
and systems. These tests may include:<BRK/>
<BRK/>
   Adhesion tests on liquid-applied or adhered waterproofing and air/weather barrier such as ASTM D4541, Test 
Method for Pull-off Strength Coatings Using Portable Adhesion Testers.<BRK/>
   Air leakage testing of fenestration or opaque walls using a site-built test chamber to provide different pressures 
such as ASTM E783, Test Method for Field Measurement of Air Leakage through Installed Exterior Windows and Doors.<BRK/>
   Small scale tests of waterproofing or air weather barriers such as the bubble test described in ASTM E1186, 
Practices for Air Leakage Site Detection in Building Envelopes and Air Barrier Systems.<BRK/>
   Water penetration tests of fenestration with a site-built test chamber (same chamber as ASTM E783) per ASTM 
E1105, Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, 
and Curtain Walls by Uniform or Cyclic Static Air Pressure Difference.<BRK/>
   Water penetration testing using a hose with a calibrated nozzle such as AAMA 501.2, Quality Assurance and Diagnostic 
Water Leakage Field Check of Installed Storefronts, Curtainwall, and Sloped Glazing Systems.<BRK/>
   Adhesion and cohesion testing of sealants according to ASTM C1193, Guide for Use of Joint Sealants: Field-Applied 
Sealant Joint Hand Pull Tab.<BRK/>

may require two or more blower door systems.  Logistically there may be an upper limit to the number of blower

of up to 24 blowers being used in one test to deliver about<MET> 90,615 L/s</MET><ENG> 192,000 CFM</ENG> at 75 Pa.  This means that 
a building envelope of up to about<MET> 71,350 sq. m</MET><ENG> 768,000 sq. ft</ENG> can be pressure tested to meet a leakage rate of<MET>
 1.27 L per sec/sq. m.</MET><ENG> 0.25 cfm/sq. ft.</ENG> at 75 Pa using blower door equipment.  Trailer mounted fans that can typically 
deliver up to<MET> 28,317 L/s</MET><ENG> 60,000 CFM</ENG> may be used for both pressurization and de-pressurization.  Blower door systems 
and trailer mounted fans may also be used together in a test.  If blower door systems and trailer mounted fans 
provide insufficient air for pressure testing, the building's own air handling system can be used in lieu of blower 
door fans and trailer mounted fans.  Obtaining accurate flow reading when using a building's own air handling 
system may be especially challenging.  Delete unnecessary pressure test methods as necessary.</NPR><BRK/>

<BRK/>
<TXT>Notify the Contracting Officer at least ten(10) working days before conducting the pressure tests to provide the Government the opportunity to 
witness the tests and to monitor weather forecasts for conditions favorable for testing.  Do not pressure test until verifying that the continuous 
air barrier is in place and installed without failures in accordance with installation instructions.  During the pressure test periodically inspect 
temporarily sealed items to ensure they are still sealed.  Seals on temporarily sealed items tend to release more readily at higher pressures.  
Test data obtained after temporarily sealed items become unsealed cannot be used as input into the calculation program.  Follow the Envelope Pressure 
Test Procedures in the paragraphs below.  Submit detailed <SUB>pressure test procedures</SUB> indicating the test apparatus, the test methods and procedures,

after Notice to Proceed.</TXT><BRK/>
<BRK/>
<SPT><TTL>Extend Pneumatic Tubes and Establish a Reference Differential Pressure </TTL><BRK/>
<BRK/>
<TXT>Confirm the various zones within the envelope have a relatively uniform interior pressure distribution by establishing a representative differential 
pressure between the envelope and the outdoors with blower door or trailer-mounted fans operating.  The number of indoor pressure difference measurements 
(pneumatic hoses) required depends on the number of interior zones separated by bottle necks that could create significant pressure drops (e.g., 
doorways and stairwells).  Extend at least four pneumatic hoses (differential pressure monitoring ports) to locations within the envelope that 
are physically opposite of each other.  In multiple story buildings, especially those over three stories, extend hoses to multiple floors.  Locate 
the hose ends away from the effects of air discharge from blower test equipment.  Select one of the four (or more) interior hoses, one judged by 
the test agency to be the most unaffected by air velocity produced by blower test equipment, to serve as the interior reference pressure port.  
Extend at least one additional pneumatic hose to the outdoors (outdoor pressure port).  To the end of this hose manifold at least four hoses together 
and terminate each hose on a different side of the building.  With the envelope sealed and the blowers energized, measure the differential pressure 
using the interior reference pressure port and the four outdoor pressure ports.  Then measure and record the differential pressure by individually 
using each of the remaining three interior hoses.  Ensure each reading is within plus or minus 10 percent of the reference reading.  Thus, at an 
average 75 Pa maximum pressure difference across the envelope, the difference between the highest and lowest interior pressure difference measurements 
should be 15 Pa or less.  If this condition cannot be met, attempt to create additional air pathways within the envelope to minimize pressure differences 
within the envelope. If necessary, move the interior hose ends.  See step 2.13 of the Air Leakage Test Form in Appendix A.</TXT><BRK/>

<SPT><TTL>Bias Pressure Readings</TTL><BRK/>
<BRK/>
<TXT>With the fan pressurization equipment de-energized and the envelope sealed, obtain the differential pressure between the outdoors and the envelope.  
Record 12 bias pressure readings before the pressure test and 12 bias pressure readings after the pressure test.  Each reading is the average of 
ten or more 1-second measurements.  Include positive and negative signs for each reading.  To help dampen bias pressures that significantly contribute 
to test pressure, reduce temperature differences between indoor and outdoor air.  Temperature differences can be reduced by operating test fan 
equipment for a few minutes to replace most of the indoor air with outdoor air.</TXT><BRK/>

<SPT><TTL>Testing in Both Positive and Negative Directions</TTL><BRK/>
<NTE><BRK/>
<AST/><BRK/>
<NPR>NOTE:  The preferred way to dampen bias pressure due to wind is to test the building envelope in both the pressurization 
and depressurization directions and average the results.  Bias pressures are nonlinear and cannot be adequately 
allowed for by merely subtracting the bias from the pressure reading. Testing in both directions more effectively 
dampens bias pressures thus tolerating the occurrence of larger bias pressures during a test, up to 30 percent 
of the lowest test pressure.  Allow single direction testing only if testing in both directions cannot logistically 
be performed.</NPR><BRK/>
<AST/><BRK/></NTE>
<BRK/>
<TXT>The preferred method for testing a building envelope is to test in both the pressurized and depressurized directions.  Testing in one direction 
is only allowed if opposite direction testing cannot logistically be performed due to test equipment limitations or restrictions.  After obtaining 
the pre-test bias differential pressure readings, conduct the pressure test.  Record the envelope pressures (in units of Pascals) from one interior 
pneumatic hose (monitoring port) and the outdoor pneumatic hose(s), averaged or manifolded, with corresponding flows (in units of<MET> L/s</MET><ENG> cfm</ENG>) for 
each fan.  Record the flow rates at least 10 to 12 positive and 10 to 12 negative building pressure readings.  If conducting both positive and 
negative pressure tests the lowest allowable test pressure is 40 Pa and the highest test pressure is 85 Pa.  Keep at least 25 Pa difference between 
the lowest and highest test pressure readings.  Include the 75 Pa pressure value between the lowest and highest readings.  The 10 to 12 readings 
in each direction are to be roughly evenly spaced along the range of pressures and flows.  After testing is complete de-energize the equipment 
used to provide pressurization and obtain an additional 10 to 12 post-test bias pressure readings.  None of the bias pressure readings are allowed 
to exceed 30 percent of the minimum test pressure.  If these limits are exceeded the test fails and must be repeated. </TXT><BRK/>

[<SPT><TTL>Single Direction Testing</TTL><BRK/>
<NTE><BRK/>
<AST/><BRK/>
<NPR>NOTE:  Allowing testing in only one direction, acknowledges that very large buildings may require truck or trailer 
mounted blower equipment that logistically will not easily allow testing in both positive and negative directions.  
Because bias pressures will have a greater impact on single-direction tests, the maximum allowable bias pressure 
under these circumstances is 10 percent of the lowest test pressure.  At these generally higher pressures, the 
effects due to bias pressure is somewhat masked by the higher test pressure range. Because building envelopes 
are often leakier when measured in one direction than the other, testing in only one direction is considered less 
accurate than testing in both directions.  Assume for example, that the bias pressure in a<MET> 12 m</MET><ENG>40 foot</ENG> high building 
envelope where the temperature is<MET> -18 degrees C</MET><ENG> 0 degrees F</ENG> outside and<MET> 20 degrees C</MET><ENG> 68 degrees F</ENG> inside and with 
negligible wind is 10.5 Pa. This bias pressure can typically be assumed to be 5.25 Pa at the top of the building 
envelope and -5.25 Pa at the bottom of the building envelope.</NPR><BRK/>
<AST/><BRK/></NTE>
<BRK/>
<TXT>After obtaining the 12 aforementioned bias pressure readings, conduct the [positive][negative] pressure test.  Obtain flow rates at 10 to 12 roughly 
evenly spaced pressure readings over a pressure range of 50 to 85 Pa.  After the data is recorded, de-energize the blower equipment and obtain 
an additional 10 to 12 bias pressure readings.  None of the bias pressure readings may exceed 10 percent of the minimum test pressure.  If these 
limits are exceeded the test fails.</TXT><BRK/>

<NPR>NOTE:  Some buildings may consist of multiple zones that do not share a common air plenum and cannot easily be 
modified to do so.  Typically, these buildings are dormitories, apartment buildings, hotels and offices wherein 
occupants enter and leave each zone via a separate, exclusive, exterior door.  Walls and floors isolate each zone 
such that no discernable air pathway between zones exists.  In this case, testing cannot be performed on the entire 
building envelope; rather, several representative air barrier zones within the building are to be individually 
pressure tested.</NPR><BRK/>

<TXT>Pressure test each exterior corner zone plus at least an additional 20 percent (as measured by floor area) of remaining zones.  The Contracting 
Officer is responsible for selecting which of these additional zones to test.  If all zones pass the pressure test it is assumed that all untested 
zones also pass and no further testing is required.  If, however, any zone fails to pass the test's leakage requirements, re-seal, and re-test 
until it passes in accordance with paragraph FAILED PRESSURE TEST.  Test an additional 20 percent of previously untested zones.  If all tested 
zones pass, no further testing is needed.  If any zone in this group fails the test re-seal and re-test the zone until it passes.  Continue this 
process until all the tested zones pass.  When testing a zone, the doors to all adjacent zones that share a common surface with the tested zone 
are to have their doors opened to the outdoors.  The resulting leakage from the test zoned is that through all six surfaces (4 walls, roof, and 
floor, for a rectangular shaped zone).</TXT><BRK/>

building addition may also require pressurizing that part of the existing building that shares surfaces in common with the new building addition.  
If an air barrier is applied to the common surfaces separating the existing building from the new addition, prior to the test prop open a sufficient 
quantity of doors and windows to keep the existing building at the same pressure as the outdoors.  If an air barrier is not applied to the common

 and in conjunction with pressurization equipment, as necessary.  Use the thermography diagnostic test to establish a baseline for envelope leakage.  
Apply additional diagnostic tests (find, feel, fog or other tests) as necessary to further define leak locations and pathways discovered using 
thermography or to find additional leaks not readily detected by thermography.  Using a variety of diagnostic tests may help locate leaks that 
would otherwise go undetected if only a single diagnostic test were used.  Pay special attention to locating leaks at interfaces where there is 
a change in materials or a change in direction of like materials.  These interfaces, at a minimum, include roof/wall, wall/wall, floor/wall, wall/window, 
wall/door, wall/louver, roof mounted equipment/roof curb interfaces and all utility penetrations (such as ducts, pipes, and conduit) through the 
envelope's architecture.  Also use diagnostic tests to check for leakage between the air duct and duct damper, when the damper, under normal control

potential for condensation, presence of daylight through an architectural surface or if the leakage location could potentially cause rapid deterioration 
or mold growth of, or in the building envelope materials and assemblies.  Apply sealing measures after diagnostic testing is complete and all pressurization 
blowers are off.  To verify that the applied sealing measures are effective, re-test for leaks using the same diagnostic methods that discovered

Using a theatrical fog generator within the envelope, direct fog at suspected leakage points such as at building interfaces.  Test the following 
interfaces: roof/wall, wall/wall, floor/wall, wall/window, roof/mounted mechanical equipment.  From the vantage point immediately outside the envelope 
and opposite that of the interface being tested, observe the effect as the fog is issued.  Detection may also be further enhanced by using a scented
