S T RAT E Y sheer number of penetrations and other obstacles presented itself with a large potential of additional leakage that would negatively and needlessly effect the test results. With the large potential, representatives from the city of Fort Collins were consulted on site and a determination was made to test two areas to get the best representation that could be obtained; the first test would comprise the whole building expansion and a second test would be conducted of the future space only. The future area testing would provide the best approach to assess the construction and intent of the code. Report Findings: Below summarizes the findings, data, and other observations to make note of for any potential changes and/or remedies: The first test conducted of the entire building expansion yielded mixed results and was found that the temporary plastic barrier that was constructed above the ceiling failed shortly into the second half of the test. Further, the depressurization portion of the test would have passed the marker set, however under pressurization and after the plastic failure, twice as much air was required to achieve pressures. In moving to the second test of the future area, the full test yielded results well under the requirements set and would pass the marker. With the determination that the future area was a sufficient representation of the entire building and construction, it was felt that the entire building would have performed with similar results if the shared ceiling plenum was not present. Testing results are indicated in the table below and further identified in the Testing Procedures portion of this report. The overall results of the future area as a representation of the entire building have a leakage rate of 0.149 cfm per square foot and requiring 4,433 cfin at 75 Pa with an equivalent leakage area of 454.6 inz. cfm - :cfm/sf pass/fail Test 1 Test 2 17,655 4,433 0.378 0.149 fail pass Conclusion: With the determination and testing representations made with the future space, the new construction met and passed the requirements set forth. Strategy Groups, LLC 1415 Park Avenue West Denver, CO 80205 Banner Medica Center Addition - Air Barrier Testing August 17, 2017 Executive Summary 2 STRATE Y Executive Suuunary: Strategy Groups conducted air pressurization testing of the under construction Banner Medical Center, Health Center Expansion located in Fort Collins, Colorado. At the time of testing, the building was entering the final stages of construction with final finishes being installed. On August 171h, 2017 an air barrier test was conducted on the expansion that comprised of a new office buildout that comprised approx. 35% of the total area and a future area making up the retraining space that remained in a core and shell state. The floorplan of the areas and notes are further identified in the Appendices included within this report. The procedures used followed the setup and process for the ASTM Standard E 779, Standard Test Method for Determining Air Leakage Rate by Fan Pressurization, and was refined for the internal conditions, constraints, and criteria of the project in its final stage of completion. Testing procedures refrained from being interfered by work being performed and did not adjust any work completed. Pressurization levels were held from 25Pa to 80 Pa for pressurizing testing. The locations, setup, and procedures are further defined in the Testing Procedures portion of this report. As part of the review for area to be sampled, the typical construction was assessed for general construction standards and conformance in a spot checking method. The exterior envelope of the expansion appeared to be well constructed and spray in foam was added at the perimeter parapet detail to provide additional sealing and enhanced air tightness. It should be noted that an issue presented itself between the existing building and new expansion at the connected ceiling plenum. Since the final and operating condition of the building will have an open ceiling plenum between the two areas, there was no treasure in which to create a barrier to test against. Therefore, prior to the testing, the contractor constructed a temporary plastic barrier above the ceiling to separate the areas. Even with the great lengths and care that were taken to construct the barrier, the Strategy Groups, LLC 1415 Park Avenue West Denver, CO 80205 Banner Medica Center Addition - Air Barrier Testing August 17, 2017 Executive Summary 1 STRATE;Y Testing Procedures: The determination of the test was to assess the air barrier tightness and construction of the newly constructed expansion space to ensure that it meets the leakage requirements set forth by the City of Fort Collins. Construction was in the final stages of completion with finishes and installed and touch up being completed. The procedure used followed the ASTM standard E-779, Determining Air Leakage Rate by Fan Pressurization and the inforination presented generally follows the layout used in the ASTM designation unless otherwise noted. Further, the city of Fort Collins has produced a protocol for the testing and is included for reference in the Appendices. The requirements set forth recommend a range of induced pressures for testing from 25Pa to 80Pa with the leakage criteria set and taken at 75Pa for testing purposes. Increments of 5Pa were used for the tests to capture data points for the areas identified. Building and Test Area Description The facility is located in Fort Collins, Colorado and elevation was figured at 5.005 feet above sea level. At the time of testing, the building was in the final stages of construction with finishes complete with some cleaning and punch list items being done. Weather was fair with light winds out of the west from 9 to 11 mph with temperatures recorded at 83°F. The building expansion comprised of 18,630 SF and with approx. 35% being built out for new offices and the remaining area as future space left at a core and shell level of finish. As depicted in Figure 1 below and included in Appendix A, a demising wall from slab to structure separated the future are from the new offices and provided an adequate barrier. ........ ..... .. ... ` Figure 1 Strategy Groups, LLC 1415 Park Avenue West Denver, CO 80205 Banner Medical Center Expansion — Air Barrier Testing August 17, 2017 Testing Procedures 1 , r111. 4.1...L1 i Upon arrival and inspections of the space prior to testing, it was discovered that there was a large void between the existing building and the new office buildout at the ceiling plenum for the north third of the connection, as depicted by the clouded green line in Figure 2. The .-11:1 1.a-111 .-a ...- ceiling plenum was designed to be open and will be the final operating condition of the space. To create a separation of the spaces and barrier to test against, the contractor created a plastic separation from the walls to the structure. The construction of the barrier presented many difficulties for proper sealing and contains a large number of penetrations and obstacles as indicated in Figure 3. Further that there would be a large amount of false leakage present and could potentially fail the project. With the City of Fort Collins present, it was discussed and decided that the project should be tested as a whole and if the leakage was over the maximum amount or _ if problems presented itself, testing of the "future" area would be a good representation of the entire space and be used to meet the city requirements. Strategy Groups, LLC 1415 Park Avenue West Denver, CO 80205 Banner Medical Center Expansion — Air Barrier Testing August 17, 2017 Testing Procedures 2 Construction — Construction of the new addition was structural steel with brick veneer and an EPDM roof. The air barrier for the vertical face was a brush on surface applied membrane on a glass mat gyp. board layer. Visual inspections of the enclosure revealed a well -constructed building and appeared to be per the details and standards set forth. Additionally, via the RFI process, additional spray -in foam was added to the perimeter parapet detail to enhance the air tightness and reduce leakage pathways. The interior of the building was split out into two areas; a future area that comprises approx. 65% of the new addition and the remaining 35% for new offices. The new office construction interior areas were inclusive of finishes and trim and punch list items were being completed. Ceiling tiles were held out in areas and sufficed for proper air movement. The future area was left in a core and shell state and was separated with a full height demising wall. As stated previous, a temporary wall was constructed above the ceiling to separate the existing ceiling plenum from the newly constructed space. While the contractor did a great job in constructing, too many obstructions and penetrations existed to be confident of a tight and complete seal. Strategy Groups, LLC S T RAZE dY � A 1415 Park Avenue West Denver, CO 80205 Banner Medical Center Expansion — Air Barrier Testing August 17, 2017 Testing Procedures 3 • HVAC Systems - The HVAC system for the building utilized an overhead supply for conditioned air into the newly constructed office space. The building air handling units for the system where not in operation at the time of testing and masked off. Exhaust and other louvers were masked off for the test. For any supply louvers that connected to the existing system, louvers were masked off. The future space did not contain any HVAC units and only had space heaters to condition the space. Procedures — At the initial arrival and testing setup, site observations were performed to evaluate the condition of the space and its surrounding environment. Our observations and setup conditions revealed the following items to make note of when considering the space and resultant data of the testing performed. Pictures of the listed items are included in Appendix C of this report. • Setup of equipment and fans used for the testing was at the interior of the building. Two potentials existed and chose west door into the future space as the setup area. • Between the future space and new construction offices, there was a pinch point to note where one Y-0" x 9'-0" door existed in the demising wall between the two areas. Additional time is needed to allow the areas to stabilize between pressure steps. • As stated previous, a large area had to be masked off to separate the existing building ceiling plenum from the newly constructed area. Masked area and delineations are indicated in Appendix A. • Spot checks revealed penetrations had been sealed well in the outside wall and demising wall. The interior of the conduits did not seem to be sealed throughout and provided a potential leakage pathway in conditioned areas. • Louvers had been masked over for supply and exhaust. • Drainage elements were covered/filled to ensure seal. • Doors were installed with weather-stripping, but missing door sweeps and thresholds to create a tight seal. .Strategy Groups, LLC 1415 Park Avenue West Denver, CO 80205 Banner Medical Center Expansion — Air Barrier Testing August 17, 2017 Testing Procedures 4 As the masked area between the new and existing space presented a potential problem, the issue was reviewed with the contractor and city of Fort Collins representatives to find the best approach and intent of the test and its requirements. It was determined as a group that the building would be tested as a whole to see the completeness of the existing structure and if needed the future space would be tested and could be used as a representation of the whole building construction. Testing equipment setup was then completed and pressure tubing was run across the equipment barrier and into the adjacent spaces further defined in the layout contained in Appendix A. The equipment used to conduct the test was a Minneapolis Blower Door, 3 f fan setup manufactured by the Energy Conservatory. DG- 700 multi -function differential pressure gauges were used to assess pressure and air flow in the procedure. Additional information on the equipment is included within Appendix D of this report. • Pressurization Test for Rooms/Areas — At the commencement of the air barrier testing, all fan(s) were covered and zeroed out for a baseline reading. It was determined to take readings in SPa intervals from 251'a to 801?a for a total of 12+ data sets for the pressurization test. When the building pressure stabilized, pressure and airflow readings were taken for 30 second periods. After the set data timeframe was conducted, the building pressure was increased to the next pressure set point of 5Pa increased and a 30 second interval at a steady state was again recorded. Once all of the data was collected for the identified data sets, the fans were covered to collect post baseline values for the system. The baselines, set points for each data set, fan configurations, and additional events are marked in the associated graph in Appendix A. Once the pressurization test was completed, the fans were reversed and the test was conducted again under depressurization. Once completed, the Strategy Groups, LLC 1415 Park Avenue West Denver, CO 80205 Banner Medical Center Expansion — Air Barrier Testing August 17, 2017 Testing Procedures 5 averages and area weighted figures were used to determine the required values and pass/fail grades. All data points collected are included in Appendix A with graphs, reports, and other findings and events are recorded. Findings - The observations conducted yielded many good practices for the construction that was completed. Above conduits and penetrations had been sealed well in walls and were well visible. The whole building test yielded results under depressurization of 10,713cfin at 75 Pa of pressure, 0.23 cfin/sf, and would meet the requirements set forth. However on the pressurization portion of the test, the temporary plastic barrier gave way in areas and were not accessible to be fixed or addressed. The resultant air flow more than doubled to 24,596cfm and 0.527 cfm/sf. Since the whole building test did not pass due to the plastic tear and sealing issues, a test of the "future" area (representing 65% of the total area) was conducted as a representation of the entire new construction. Both pressurization and depressurization performed well and passed with an average of 4,432 cfm at 75 Pa and 0.149 cfm/sf on the surface area. The equivalent leakage size for the future area was 454in2• When taking into account whole building tests, the issues surrounding the temporary above ceiling plastic barrier, and the representation of the future area tests and performance, we feel that the enclosure perforted well and more than met the city requirements. The city of Fort Collins protocol forms and certifications of compliance are included in Appendix B of the report. Finally, depending on the length of time the future space may be incomplete, it is recommended to look at sealing the top of the demising wall, at the metal flutes to mitigate unconditioned air transferred into the occupied areas.
