1 Demystifying Testing Standards C t B ildi F d Common to Building Facades John Runkle, P.E. Director, Forensic Services Architectural Testing, Inc. Architectural Testing Learning Objectives Understand laboratory and field test standards related to building envelope performance. Identify and manage risks that could impact the test results. Learn the benefits and limitations of laboratory testing with respect to actual field performance. D l d t di f h t l t th b t Develop an understanding of how to select the best performance predictors for future projects. 1
