Dr. John Straube

Ph.D., P.Eng. Waterloo, Canada

Principal, Senior Building Science Specialist

John Straube is a building science engineer working in RDH’s Toronto and Waterloo offices. John heads forensic investigations and leads research projects in the areas of low-energy building design, building enclosure performance, hygrothermal analysis, and field monitoring of wall assemblies. He is also a prolific writer, a noted public speaker, and a sought-after “performance coach” who helps other professionals coordinate their efforts and achieve higher levels of performance in their building projects. As one blogger wrote after attending a keynote speech: “he clearly loves what he does.”

In addition to his work with RDH, Dr. Straube is a cross-appointed faculty member in the School of Architecture and the Department of Civil and Environmental Engineering at the University of Waterloo. He was a Principal at Building Science Corporation from 2006 to 2013, and is the co-author, with Eric Burnett, of Building Science for Building Enclosures, one of few texts available with a specific focus on the principles of building science. Dr. Straube’s leadership as a building scientist and an educator has been recognized with multiple awards, including the Lifetime Achievement Award in Building Science Education from the National Consortium of Housing Research Centers (NCHRC).
