He is a building scientist who investigates building failures and is internationally recognized as an authority on moisture related building problems and indoor air quality. He is an Adjunct Professor of >Civil Engineering at the University of Toronto and the past chairman of ASTM E241 - Increasing the Durability of Building Assemblies from Moisture Induced Damage. He is a contributor and reviewer of Chapters 21 and 22 of ASHRAE Fundamentals. Dr. Lstiburek is an ASHRAE fellow.

Dr. Lstiburek has appeared on PBS NOVA ("Can buildings make you sick?") and is the author of numerous books and technical papers on building science, indoor air quality and durability. He is the author of the U.S. DOE Handbook on Moisture Control and a special contributor to the EPA guidance document on Building Air Quality: A Guide for Building Owners and Facility Managers. He is one of the world's foremost authorities on energy efficient construction techniques and heads one of the four the Building America program teams for the U.S. Department of Energy. He is the developer of ADA (the Air Drywall Approach to air barriers) and a building science researcher affiliated with the Centre for Building Science, University of Toronto. He is a former Director of Research of the Housing and Urban Development Association of Canada.

Dr. Lstiburek has written numerous books and technical papers on building construction. He is the best selling author of the Builder Guides and has over 50 technical and journal articles to his credit.
