ThermalWise completed two site visits. Fist site visit included two window water penetration tests and two window air leakage tests at the OPS building. The second site visit included building air leakage site detection and whole building thermographic inspection. Window Water Penetration Testing was conducted in general accordance with ASTM E1105. Window Air Leakage Testing was conducted in general accordance with ASTM E783. Air Leakage Site Detection was conducted in general accordance with ASTM E1186 section 4.2.1 Building Depressurization (or Pressurization) with Infrared Scanning Techniques. Whole Building Thermographic Inspection was conducted in general accordance with ASTM C1060.

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.
