ThermalWise completed wall air leakage testing at the Dominion Building in Charlottetown, PEI. The purpose was to quantify the air leakage rate across the sections of the exterior wall of the first floor of the building. The air leakage rate was taken into consideration when designing the air supply for a proposed dynamic buffer zone system. 

ThermalWise completed thermographic scans at the Newfoundland Mental Health and Addictions Facility in St. John’s, NL. The purpose was to identify thermal anomalies in the building enclosure utilizing thermographic imaging in conjunction with building pressurization. The existing building mechanical system was used to create the interior to exterior pressurization differential required. 

ThermalWise conducted field quality assurance water penetration of installed curtain wall and window-wall specimens at the Halifax YMCA, in Halifax, NS. The water tightness performance specifications are 575 Pa for curtain wall test specimen and 500 Pa for the window-wall test specimen, in accordance with the project specifications. The purpose of the testing was to verify test specimens’ installed field performance against project performance expectations.

ThermalWise conducted two whole building air leakage tests (WBALTs) at the Wing Telecommunications Upgrade and Information Services Upgrade Personnel and Shops Facility (PSF) at CFB Shearwater, Nova Scotia. The purpose of the testing was to verify the whole building air tightness functional performance against project specifications at two stages of construction – completion of the air barrier system; and at or near construction completion.

ThermalWise completed a thermographic evaluation and blower door testing of the Alexander Graham Bell Museum in Baddeck, NS.  

ThermalWise conducted quantitative air leakage testing in general accordance with the US Army Corps of Engineers (USACE) and Air Barrier Association of America (ABAA) Air Leakage Test Protocol for Building Envelopes. This protocol is widely referenced as the standard for whole building air leakage testing of large building envelopes. It is underpinned by ASTM E779. The protocol includes testing under positive and negative pressure and reporting the building envelope’s air leakage as a normalized reading at 75 Pa (CFM@75Pa/ft2), which is typical for larger buildings. This protocol includes supplying the air leakage curve equation, which allows for calculating the leakage of the building at any pressure difference. ThermalWise provided ACH@50Pa as well as m3/hr@50Pa results.

The protocol also references determining pathways of air leakage using ASTM E1186. ThermalWise completed this using thermal imaging of the building under positive and negative pressurization. ThermalWise also used thermal imaging to identify thermal bridges and other defects in the building envelope. 

ThermalWise completed one whole building air leakage test on the Service Canada Centre in Marystown, NL, in general accordance with ASTM E779.

ThermalWise was contracted by MacLeod Group to conduct water penetration testing at the long-term care facility building located in Mahone Bay, NS. 

Testing, conducted in general accordance with ASTM E-1105, was performed on December 16, 2022, on three PVC frame punched windows. 

MacLean Construction contracted ThermalWise to conduct whole building air tightness testing of the new addition to the West Royalty School located in Charlottetown, PEI.

ThermalWise conducted whole building air tightness testing at the Highland Village Redevelopment Project in Iona, Nova Scotia.  The purpose of the testing was to determine the whole building air tightness at the post-drywall stage of construction.

Testing, conducted in general accordance with ASTM E-1105, was performed on one Anotec 3400 aluminum frame curtain wall test specimen, and one Antamex aluminum frame curtain wall test specimen. 

ThermalWise completed air tightness testing and air leakage site detection using thermographic imaging at two stages of construction. The first stage was conducted once all building envelope components were installed. The second stage was performed after all building components were in place and construction completed.

 General Air Tightness Testing Procedure (based on subsection 3.1.1 and 3.1.2 of section 07 27 00): the mean value of the air leakage flow through the exterior envelope for a negative and positive pressurization air leakage test must not exceed 0.25 CFM/ft2 @75Pa. Air leakage testing is required to be performed in general accordance with ASTM E779 with additional requirements included in the construction specification. 

 Building Air Leakage Site Detection: thermography-based air leakage site detection took place in conjunction with the air leakage testing for both Stage 1 and Stage 2 testing. This testing was performed in general accordance with ASTM 1186.
