Air Barrier Adventure An Impossible Air Tightness Goal Achieved Angela Cardwell, Executive Vice President, Joeris General Contractors, Ltd. Contributors: Jorden Eiden, Matt Dunn, Henry Serry

Background and Introduction Steve Hennigan, President/CEO of Credit Human, is not your normal seeker of efficiency and sustainability. No. Steve Hennigan wants it ALL, and he wants it to perform at the highest levels you can imagine, not those you just think you can achieve. He wants the impossible. This mindset set the stage for Joeris’ management of the construction of the new headquarters for Credit Human. The entire project sought to exceed anyone’s idea of what it means to own and operate a truly sustainable facility. From living green walls, to solar installations, to geothermal units – Credit Human’s new office space is one of only a few such buildings in the United States, LEED Platinum qualified and beyond Net Zero to Net Producing. All this a result of Hennigan’s vision. One part of this vision was Hennigan’s challenge to the team regarding the building’s envelope and its air barrier performance. This paper analyzes the journey that led to not just meeting Steve’s challenge but exceeding it in grand fashion.

The Players While the Credit Human building incorporates many sustainable features and design elements, this paper is focused on the building envelope and air barrier performance. To meet the challenge defined by Steve Hennigan, several voices needed to be engaged in the conversation. These included the architects, engineers, Joeris as the construction manager, several MEP trade partners, local inspectors, and Steve, himself. To give full credit where it is due, the following firms were integral to the success of the building envelope air barrier challenge. • • • • • • •

The Challenge Steve Hennigan has very strong convictions about sustainability and has always been quick and passionate in showing the long-term benefits of sustainability initiatives, often through the example of implementation in his own home. Steve learned a lot about the challenges of constructing a tight envelope on his house. The concept of the air barrier and a tight building slowly developed as the design developed. Eventually, mention of the Corps of Engineers’ standard for building tightness was introduced (.25cfm/sf@75pa). While the standard is tough to meet, Steve laid down the gauntlet and challenged the team to exceed it, even offering an incentive to all involved if the more challenging goal he set could be met. Steve’s challenge set the goal at 0.1 cfm/sf @75pa, less than half the Corps’ standard. Once the team got beyond the initial instinct of declaring the goal’s impossibility, everyone worked together to devise a plan to make it happen. Steve’s passion drove the team to want to achieve the impossible. The team declared that they would be successful in turning the impossibility into reality.

The Process We had no idea how this project would transform our team, or company–all because of the challenge and vision of Steve Hennigan. Steve Hennigan first met with our project team to introduce the sustainability initiatives post-award. Joeris was awarded the project because of our established relationship with the developer and our ability to support that relationship with a team of people with strong resumes to suit this unique build. With the right people together in the right place at the right time, the team was assembled. As the project design developed, Steve’s vision started becoming apparent. Steve sat in many of the design meetings and challenged the engineers and architects as to how they were approaching their design. He even sat at the table and ran his own calculations to either validate or challenge those of the engineers. It became obvious very quickly that he was deeply invested in his vision and desired outcomes regarding sustainability. There were early discussions with Steve concerning the roof system. He used the analogy of why you wear a heavy, insulated hat in the winter so you don’t lose all your body heat through the top of your head. These roof insulation discussions led to wall insulation and air barrier discussions. The Joeris team led discussions dealing with the window systems. It was important to our team, for quality control purposes and speed of installation, that we use a “unitized” or pre-glazed system. All these elementspecific discussions started coming together into a wholistic design of the building envelope. While the building envelope design was developing, so were the other sustainability initiatives. Early on, the project team was approaching the sustainability initiatives as “alternates” and doing a lot of comparative analysis to more conventional systems. But the further the design developed, the more apparent it became that the sustainability initiatives were going to be funded and become integral to the project. During this project Henry Serry, Joeris COO, recalled watching a documentary on Walt Disney and it reminded him of the way that Steven Hennigan functions. The documentary showcased how Walt Disney employed the best and the brightest and drove them to near perfection. When Disney’s teams finally got to the point where everyone thought that the project could not get any better, he would ask them for one more thing. Just one more thing to make it even better. That is how Steve Hennigan approached the Credit Human project. If he could fit one more geothermal well, or one more solar

panel, if he could squeeze in another ½” of insulation, he firmly believed that it was worth it. The team was constantly challenged to find that one more thing. Once the team chose to take on the impossible air barrier challenge, Joeris put together a quality control plan and associated budget. Our team determined that we would be successful and built it into the project staffing and budget. Project ownership then supported it. The project ownership found a way to encourage the entire project team’s ability to meet the building tightness challenge. They presented the idea of contractually setting the goal/requirement at the Corps of Engineers’ standard. Team members involved in the building envelope process were then offered a variable incentive for beating the Corps of Engineers’ standard. As it turned out, collectively we shattered the standard.

Requires full time supervision, depending on project size o Utilized carpenter staff to help fix and keep up with testing and schedule. Make sure surfaces are clean. Pay attention to details. Use manufacturer recommended and/or required primers. Sealant joints cleaned of mortar while brick installation occurs. This will help sealant installation and discrepancy of who cleans and delays. The concept of layers on layers of compatible materials to ensure no deficiencies, whether it’s from installation or exposure to elements. Build your own test chambers to keep up with testing. Curtain wall testing E1105 o Use 2x4 for large windows or 1x4 for smaller windows. o Order Vinyl Clear 10 gauge from Joanne Fabrics. Concrete will leak air at cracks, joints of any kind and honeycomb. Have mason anchor jack lines to steel and not screw into wall or hang on brick ties. Make sure brick ties are sealed at location and angle for the brick (Masons would twist or move brick ties and joints would crack or break and now be compromised for air leakage). Dow 795 Needs a Primer to be successful. Either Primer P or Primer C. Complete ASTM E779 and ASTM C1060 through TSI. We performed E1105 test with PSI and Raba, part of the curtain wall/window testing and AMMA 501.2.

Water Penetration E1105 Test Criteria

6.I. WATER PENETRATION TEST CRITERIA (E1105 TEST)


Designation: E1105 – 00 (Reapproved 2008)

Standard Test Method for

Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, and Curtain Walls, by Uniform or Cyclic Static Air Pressure Difference1 This standard is issued under the fixed designation E1105; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.

1. Scope 1.1 This test method covers the determination of the resistance of installed exterior windows, curtain walls, skylights, and doors to water penetration when water is applied to the outdoor face and exposed edges simultaneously with a static air pressure at the outdoor face higher than the pressure at the indoor face. 1.2 This test method is applicable to any curtain-wall area or to windows, skylights, or doors alone. It is intended primarily for determining the resistance to water penetration through such assemblies for compliance with specified performance criteria, but it may also be used to determine the resistance to penetration through the joints between the assemblies and the adjacent construction. Other procedures may be appropriate to identify sources of leakage. 1.3 This test method addresses water penetration through a manufactured assembly. Water that penetrates the assembly, but does not result in a failure as defined herein, may have adverse effects on the performance of contained materials such as sealants and insulating or laminated glass. This test method does not address these issues. 1.4 The proper use of this test method requires a knowledge of the principles of pressure measurement. 1.5 The values stated in SI units are to be regarded as the standard. The inch-pound equivalents of SI units may be approximate. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see 7.1.

1 This test method is under the jurisdiction of ASTM Committee E06 on Performance of Buildings and is the direct responsibility of Subcommittee E06.51 on Performance of Windows, Doors, Skylights and Curtain Walls. Current edition approved April 1, 2008. Published May 2008. Originally approved in 1986. Last previous edition approved in 2000 as E1105 – 00. DOI: 10.1520/E1105-00R08.

2. Referenced Documents 2.1 ASTM Standards:2 E631 Terminology of Building Constructions 3. Terminology 3.1 Definitions—For definitions of general terms relating to building construction used in this test method, see Terminology E631. 3.2 Definitions of Terms Specific to This Standard: 3.2.1 specimen, n—the entire assembled unit submitted for test as installed in the exterior wall of a building. 3.2.1.1 Discussion—The test specimen consists of the major components of the assembly, including all joints, cracks, or openings between such components and any panning, receptors, extenders, sills, mullions, or other parts or components used for assembling any installation. The joints between assemblies and the openings into which they are mounted (masonry openings, for example) are not part of the test specimen. However, these joints may be tested by this procedure. 3.2.2 test pressure difference, n—the specified difference in static air pressure across the closed and locked or fixed specimen expressed in pascals (lbf/ft2). 3.2.3 water penetration, n—penetration of water beyond a plane parallel to the glazing (the vertical plane) intersecting the innermost projection of the test specimen, not including interior trim and hardware, under the specified conditions of air pressure difference across the specimen. For products with non-planer surfaces (domes, vaults, pyramids, etc.) the plane defining water penetration is the plane defined by the innermost edges of the unit frame. 4. Summary of Test Method 4.1 This test method consists of sealing a chamber to the interior or exterior face of specimen to be tested, supplying air 2 For referenced ASTM standards, visit the ASTM website, www.astm.org, or contact ASTM Customer Service at service@astm.org.

E1105 – 00 (2008) to a chamber mounted on the exterior or exhausting air from a chamber mounted on the interior, at the rate required to maintain the test pressure difference across the specimen while spraying water onto the outdoor face of the specimen at the required rate and observing any water penetration. 5. Significance and Use 5.1 This test method is a standard procedure for determining the resistance to water penetration under uniform or cyclic static air pressure differences of installed exterior windows, skylights, curtain walls, and doors. The air-pressure differences acting across a building envelope vary greatly. These factors should be considered fully prior to specifying the test pressure difference to be used. NOTE 1—In applying the results of tests by this test method, note that the performance of a wall or its components, or both, may be a function of proper installation and adjustment. In service, the performance will also depend on the rigidity of supporting construction and on the resistance of components to deterioration by various causes, vibration, thermal expansion and contraction, and so forth. It is difficult to simulate the identical complex wetting conditions that can be encountered in service, with large wind-blown water drops, increasing water drop impact pressures with increasing wind velocity, and lateral or upward moving air and water. Some designs are more sensitive than others to this upward moving water. NOTE 2—This test method does not identify unobservable liquid water which may penetrate into the test specimen.

5.2 Laboratory tests are designed to give an indication of the performance of an assembly. Field performance may vary from laboratory performance since the supporting structure for the test specimen, methods of mounting, and sealing in the laboratory can only simulate the actual conditions that will exist in the building. Shipping, handling, installation, acts of subsequent trades, aging, and other environmental conditions all may have an adverse effect upon the performance of the installed product. This field test procedure provides a means for determining the performance of a product once installed in the building. 5.3 The field test may be made at the time the window, skylight, curtain-wall, or door assemblies are initially installed and before the interior of the building is finished. At this time, it is generally easier to check the interior surfaces of the assemblies for water penetration and to identify the points of penetration. The major advantage of testing when assemblies are initially installed is that errors in fabrication or installation can be readily discovered and corrections made before the entire wall with its component assemblies is completed at which time the expense of corrective work may be increased many times. 5.4 The field test may also be made after the building is completed and in service to determine whether or not reported leakage problems are due to the failure of the installed assemblies to resist water penetration at the specified static air pressure difference. Generally it is possible to conduct tests on window, skylight, and door assemblies without too much difficulty, and to identify sources of leakage. A curtain-wall assembly, on the other hand, may not be accessible from the inside without the removal of interior finished walls and ceilings. Even with removal of interior walls and ceilings, it may not be possible to observe curtain-wall surfaces behind

spandrel beams. The feasibility of conducting a meaningful static air pressure difference water penetration test on an in-service building must be carefully evaluated before being specified. 5.5 Weather conditions can affect the static air pressure difference measurements. If wind gusting causes pressure fluctuation to exceed 6 10 % from the specified test pressure, the test should not be conducted. 5.6 Generally it is more convenient to use an interior mounted pressure chamber from which air is exhausted to obtain a lower pressure on the interior surface of the specimen. A calibrated rack of nozzles is then used to spray water at the proper rate on the exterior surface. Under circumstances where it is desirable to use an exterior-mounted pressure chamber, the spray rack must be located in the pressure chamber and air supplied to maintain a higher pressure on the exterior surface. Exterior chambers are difficult to attach readily and seal to exterior surfaces. 5.7 Even though the equipment requirements are similar, this procedure is not intended to measure air infiltration because of the difficulty of isolating the component air leakage from the extraneous leakage through weep holes, mullion joints, trim, or other surrounding materials. 6. Apparatus 6.1 The description of apparatus in this section is general in nature, and any arrangement of equipment capable of performing the test procedures within allowable tolerances is permitted. 6.2 Major Components (Fig. 1): 6.2.1 Test Chamber—A test chamber or box made of plywood, plastic, or other suitable material and sealed against the test specimen. Test chambers mounted on the interior must be made so that interior surfaces and joints of the specimen can be easily observed for water penetration during the test. No part of the testing chamber shall come in contact with or restrict any point where water pentration may occur. At least one static air pressure tap shall be provided to measure the chamber air pressure versus the ambient (interior-exterior) air pressure and shall be so located that the reading is unaffected by exterior impinging wind, or by the velocity of air supply to or from the chamber. The air supply opening into or exhaust from the chamber shall be arranged so that air does not impinge directly on the test specimen with any significant velocity. A means of access into the chamber may be provided to facilitate adjustments and observations after the chamber has been installed. 6.2.2 Air System—A controllable blower, compressed air supply exhaust system, or reversible blower designed to supply the required maximum air pressure difference across the specimen. The system must provide essentially constant air flow at a fixed pressure for the required test period. 6.2.3 Pressure Measuring Apparatus—A device to measure the test pressure difference within a tolerance of 62 % or 62.5 Pa (60.01 in. of water column), whichever is greater. 6.2.4 Water-Spray System—The water-spray system shall deliver water uniformly against the exterior surface of the test specimen at a minimum rate of 3.4 L/m2·min (5.0 U.S. gal/ft2·h).

FIG. 1 General Arrangement of Water Penetration Test Apparatus

NOTE 3—The National Weather Service Technical Paper No. 403 records that in the contiguous 48 United States, the greatest rainfall for a 1-h period is less than 12.7 cm (5.0 in.). The rate of 3.4 L/m2·min (5.0 U.S. gal/ft2·h) specified in this test method corresponds to a rainfall of 20.3 cm (8.0 in.)/h unless otherwise specified.

6.2.4.1 The water-spray system shall have nozzles spaced on a uniform grid, located at a uniform distance from the test specimen and shall be adjustable to provide the specified quantity of water in such a manner as to wet all of the test specimen, uniformly and to wet those areas vulnerable to water penetration. If additional nozzles are required to provide uniformity of water spray at the edge of the test specimen, they shall be equally spaced around the entire spray grid. 6.2.4.2 The intake water line to the nozzle grid shall be equipped with a pressure gage and pressure adjusting valve. For field testing, the water pressure shall be adjusted to the same pressure at which the water spray system was calibrated. 7. Hazards 7.1 Warning—Glass breakage will not normally occur at the small pressure differences applied in this test method.

Excessive pressure differences may occur, however, due to error in operation or gusting wind, therefore, exercise adequate precautions to protect personnel. 7.2 Take whatever additional precautions are necessary to protect persons from water spray, falling objects (which may include tools), the spray system, or even the exterior test chamber. 8. Examination of Test Specimens 8.1 Select and identify the test specimen in accordance with the procedures established in Section 10. 8.2 Conduct a detailed visual examination of the test specimen and the construction adjacent to the test specimen. Record all pertinent observations. 8.3 If the intent is to test an operable window, skylight, or door, the unit should be checked for proper installation by opening, closing, and locking the unit five times prior to testing, with no further attention other than the initial adjustment.

E1105 – 00 (2008) NOTE 4—The purpose of this examination is to record the physical condition of the test specimen and adjacent construction at the time of testing. Examples of pertinent observations to be recorded include; any damage or deterioration observed, missing or broken components, missadjustment or weatherstrip or other components, cleanliness of the test specimen, out-of-square installations, and so forth.

9. Calibration 9.1 The ability of the test apparatus to meet the applicable requirements shall be checked by using a catch box, the open face of which shall be located at the position of the face of the test specimen. The calibration device is illustrated in Fig. 2. The catch box shall be designed to receive only water impinging on the plane of the test specimen face and to exclude all run-off water from above. The box shall be 610 mm (24 in.) square, divided into four areas each 305 mm (12 in.) square. Use a cover approximately 760 mm (30 in.) square to prevent water from entering the calibration box before and after the timed observation interval. The water impinging on each area shall be captured separately. A spray that provides at least 1.26L/min (20-gal/h) total for the four areas and not less than 0.25 L/min (4 gal/h) nor more than 0.63 L/min (10 gal/h) in any one square shall be acceptable. 9.1.1 The water-spray system shall be calibrated at both upper corners and at the quarter point of the horizontal center line (of the spray system). If a number of identical, contiguous, modular spray systems are used, only one module need be calibrated. The system shall be calibrated with the catch boxes at a distance within 651 mm (2 in.) of the test specimen location from the nozzle. The reference point for location of the spray system from the specimen shall be measured from the exterior glazing surface of the specimen farthest from the spray system nozzles. Recalibrate at intervals necessary in the judgment of the testing agency but not more than six months. 9.1.2 When the calibration is made, record the water pressure on the intake water line to the nozzle grid. When a field test is made, make sure to adjust the water pressure on the intake line to the pressure recorded when the grid was calibrated.

10. Information Required 10.1 The specifying authority shall supply the following information or provide guidance relative to its specification. NOTE 5—Although the specifying authority is responsible for establishing test specimen sampling, selection, and identification procedures, such procedures or modifications to said unit should be mutually agreed upon by all parties involved prior to testing.

10.1.1 Test specimen sampling, selection, adjustment, and identification. 10.1.2 Test pressure difference(s) to be applied during the test. 10.1.3 Whether uniform or cyclic air pressure difference tests, or both, shall be used. Duration and number of cycles if cyclic test is used. 10.2 Unless otherwise specified, failure criteria of this test method shall be defined as water penetration in accordance with 3.2.3. Failure also occurs whenever water penetrates through the perimeter frame of the test specimen. Water contained within drained flashing, gutters, and sills is not considered failure. 11. Preparation of Test Apparatus 11.1 Fit the test chamber to the perimeter of the test specimen to cover the entire assembly through which a check for water penetration is to be made. Provide suitable support for the test chamber so that it does not contact or restrict any point where water leakage may occur. Seal all joints between the test specimen perimeter and the test chamber. Seal any openings between the test chamber and any air supply or exhaust ducts, pressure taps, or other measuring devices. 11.2 Establish a means for measuring the air pressure difference across the test specimen which takes into account the difference that may exist between the static pressure in the interior of the building and the static pressure on the exterior. In the case of an interior mounted test chamber, it may be possible simply to open a window in a room to balance the pressure. A pressure tap to the exterior for a pressure measuring

Test Report No: 18018‐QAD001‐R0 Report Date: 11/28/18

Abstract:

The intent of this evaluation is to ensure that the design and assembly of each selected specimen meet the prescribed water penetration resistance requirements as defined by the contract documents. The results of this evaluation are provided for the exclusive use of Joeris General Contractors. Scope: Conduct a quality assurance and diagnostic field test to determine water penetration resistance performance of the selected assembly. Testing Procedure: A precursory review of the relevant drawings, details, and submittals was performed prior to arriving on site for testing. Visual observations and photographic documentation of initial conditions were recorded. Unless otherwise indicated, sample framing and joints were tested from left to right (when viewed from the exterior), beginning with the lower left‐hand corner of the sill, advancing vertically and concluding at the right corner of sample head. Test Method(s): AAMA 501.2‐09, Quality Assurance and Diagnostic Water Leakage Field Check of Installed Storefronts, Curtain Walls, and Sloped Glazing Systems Water Penetration: For the purpose of this test, water penetration or “leakage” shall be defined as any uncontrollable water that passes through or between the materials of a system, into a space not intended for moisture exposure, appearing on any normally exposed interior surface, that is not contained or drained back to the exterior, or that can cause damage to adjacent materials or finishes.

Test Report No: 18018‐QAD001‐R0 Report Date: 11/28/18

Observations:

Curtain wall system installed without finished cap trim. Full perimeter sealant with backer rod was observed but installation of second layer of sealant and backer rod per approved shop drawings could not be determined. Screws broken off/missing from pressure bars (Photo 4). Weep holes installed per design (Photo 5). End dams installed and sealed per design (Photo 6). Waterproofing coverage appeared sufficient with minimal deficiencies/pinholes however, membrane flashing was bubbling in multiple areas. Testing Conditions:

Weather: 55.2o F, Sunny and Clear, 2.5 mph Wind. Significant Modifications / Deviations from Standard Test Method: Test samples are not representative of a “complete system”. Initial testing is intended to test the installed waterproofing around the curtain wall system. Sample can be re‐tested after façade installation if desired.

Specimen Description(s): TEST SPECIMEN DESCRIPTION* # 1. East Mockup, 1/3 width (scale), North Bldg.

INSTALLATION CONDITIONS / OBSERVATIONS

Incorrect flashing used at rough opening, CCW‐705‐TWF in lieu of CCW‐705 (Photo 8), flashing insufficiently lapped at 2. South Mockup, ½ width (scale), South Bldg. change in lug elevation/depth (Photo 9), edges of membrane flashing rolling at left jamb framing and lacking sealant (Photo 10). *Note: Viewpoint orientation for all location references is from the exterior of the sample.

TEST TIME

RESULTS (Pass/Fail)

OBSERVATIONS

45 seconds into testing, leakage was observed 1. Test 10:05 Fail entering the concrete joint below the right corner of the sill (Photo 7). Testing was re‐started at the left side of the sill 1. Test Pass and continued for the entire perimeter framing of the left pane with no visible leakage. Similar to Sample 1, leakage was observed entering the concrete joint below the right corner of the sill. Testing continued, and additional leakage was observed penetrating the jamb 2. Test 12:00 Fail flashing at the right jamb when water was applied at 5’‐2” up on the framing. Exterior flashing was observed to be rolled back/not properly sealed at this point (Photo 10). Testing was re‐started at the base of the left jamb 2. Test Pass framing and continued for the entire perimeter framing of the left pane with no visible leakage. *Note: Viewpoint orientation for all location references is from the interior of the sample. Analysis: Leakage observed at Sample 1 did not appear to be a failure of the waterproofing or curtain wall systems. The leakage appeared to be the result of water entering the concrete joint between the site‐ cast architectural concrete column, the structural concrete column, and the cast‐in‐place concrete band. Initial leakage at Sample 2 appeared to be the result of water penetrating the concrete joint below the applied waterproofing. The second leak that occurred at 5’‐2” up on the jamb framing was recreated multiple times and appeared to be the direct result of the incorrect termination of the membrane flashing of the rough opening. Exposed flashing edges/terminations should be sealed with approved sealant.

Air Barrier/Air Pressurization Level 6 Mock-up Test Agenda

7.II. AIR BARRIER/AIR PRESSURIZATION TEST LEVEL 6 MOCK-UP TEST AGENDA


Our Mission is to Transform People and Places

Air Barrier/Air Pressurization Mock-Up Test Agenda Thursday, May 16, 2019 6:56 AM Agenda Purpose:

To demonstrate the effectiveness of our materials, design, installation, and quality control in striving to achieve a .1 CFM/SF air leakage rate on the Broadway Office Development project. I.

II.

Quality Control Measures a. Sequence i. Sheathing —» Brick ties/MWP clips —> Air Barrier —» QC b. Supervision i. Deano and Jordan c. Issues management i. Deano, Jordan, and Ryan I. Daily Checklists I. Any issues are noted and addressed using PlanGrid I. Deficiencies have decreased substantially from building mockup to building application. Mock-Up a. Location: South Building/southwest corner of level 6 i. Per E779— Mock-up is located in a corner of the building, this being the most difficult location to achieve rate that will be required for entire project. b. Corner conditions i. No tie in between exterior air barrier and interior temp walls. This was a detail that only pertained to the air barrier mock-up and presents itself as a vulnerable location of the mock-up. The building air barrier will be tested as a continuous whole during the final inspection and should yield better results in lieu of this particular mock-up detail. Per ASTM E779 — Exterior corners of building conditions have an increased amount of exterior pressure, therefore making those locations more susceptible to air leakage. c. SF Calculations i. Conservative in our calculations including • Exterior walls • Floor and ceiling • Interior walls Total SF calculated —4,837.5 SF d. CFM’s allowed to meet standards i. Standard: .25 cfm/SF (Allowable CFMs 1,209) ii. T ¿agt: .1 cfm/SF (Allowable CFMs 484 CFMs) e. Initial pressurization (positive and negative) i. Test was performed to ASTM 1186 which follows guidelines for pressurizing/depressurizing a chamber then using smoke to identify air leakage sites. ii. Room was filled with smoke, and pressurization of the room was implemented. During the test the positive pressure was increased to around 212 pascals, then depressurized the room to around 150 pascals to help identify air leaks.

Initial tests resulted in air leakage primarily at the mock-up partition walls. Initial test results were on the high side for both positive and negative air pressure tests. Tests were reading around 1577 cfm depressurized around 1499 cfm’s. v. The following areas were reviewed: i. Seals around windows, ii. between windows and rough openings, iii. gap where panels lock together, iv. connection between window frames and floor, v. around embeds/angles at bottom of slab above, vi. horizontal seams in sheathing, vii. between framing and concrete columns, viii. connection of window frames and walls above, ix. concrete cold joints (learned that this area yields itself to air leakage under high pascal testing. On the building final inspection this should not be an issue since the air barrier will encapsulate all these conditions). vi. There was one area where smoke was exfiltrating above the window on the northern end of the west elevation. i. this area was re-sealed and re-tested, with not smoke being identified. ii. Lesson learned: do a second visual inspection of the sealant. This can be done as we are coming down the building elevation on mast climbers. vii. Window connections where the pre-glazed window systems are assembled in the field: i. These locations were a concern, and an area of focus. ii. These locations tested really well and showed no signs of air leakage. viii. Infrared testing under negative pressure (Minimal temperature differences) i. Test did not show any significant temperature changes f. Addressing of mock-up specific issues i. Conditions noted above. ii. Partition walls were also re-sealed around the perimeter where air leakage was present. g. Re-testing results i. Positive pressure: 75 pascals, 519 CFMs equating to 0.1073 Negative pressure: 75 pascals, too Iow to get a reading. Overall performance at pre-test. 1. TSI — will be issuing a report of their findings a. Encouraged by the proactive measures being taken to provide an airtight airbarrier. Process for Today’s Test a. ASTM E779 b. Corps of Engineers sequence and standards i. Positive and Negative pressure readings 1. Positive Pressure: 75 pascals, 515 CFMs equating to .1065 CFMs/OF 2. Negative Pressure: 80 pascals, too low to get a reading. ii. Readings for each reading. Both need to meet the standard Summary of Results/Current Status a. TSI i. Broadway Evaluation 1. Overall, the results of the test were positive, and are falling in line to achieve the .1 CFM/SF air leakage rate on the Broadway Office Development project. ii. Where do we go from here? 1. Action Steps a. Continue daily checklists of the building envelope b. Continue to use the air-leakage testing device c. Continuous visual inspections d. Review and make sure that permanent and temporary core walls are sealed properly, so when final test is performed, they are not a factor.

Level 6 Mock-Up Findings o

o

Top and bottom of wall were the weakest points, in particular the floor as dust and debris were not cleaned and wiped before acoustical sealant was installed, causing a leak. We used several layers of sealant to stop the leaks. Screw heads that were not tape and floated or having air barrier applied also leaked.

Lessons Learned o

One layer of sealant at bottom of wall is not enough and substrate needs to be clean.

o

Using the concept of Layers on Layers is ideal

o

Quality of installation is the biggest issue. Products work if given the time and skill to do it right.

Summary of Findings • • •

Brick ties not fully sealed at the pad and screw head. o Most leakage was observed around the screw head through the washer. Air barrier product installed “horseshoed” around some penetrations.

Locations where screws had been improperly installed, then removed, leaving an open hole through the air barrier system.

Verify transition from concrete to sheathing on each level to confirm air barrier continuity at the corner details.

• •

Some window flashing has begun to separate along the opening. Individual attention may be necessary at each tie after air barrier has been sprayed to reduce leaks at these know weak points.

All the notes and findings from previous inspection still apply. Testing and repairs should continue as necessary while working around the building.
