Dr. Joseph Lstiburek is a principal of Building Science Corporation. Dr. Lstiburek’s work at BSC ranges widely, from investigating building failures to overseeing research and development projects, to writing articles and books as well as educating industry professionals. A building science pioneer, particularly in the areas of air barriers, vapor barriers, and vented and unvented assemblies, he has had a lasting impact on building codes and practices throughout the world. Dr. Lstiburek founded BSC in 1991, and has been a key figure in establishing it as one of the most influential and respected building science firms in North America.

Dr. Lstiburek has been a licensed Professional Engineer in the Province of Ontario since 1982 and is an ASHRAE Fellow. 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 also worked on the Canada-wide Super Energy Efficient Housing R-2000 program and served as senior engineer on commercial construction projects for Trow in Toronto. Dr. Lstiburek is also a former Director of Research of the Housing and Urban Development Association of Canada.

Dr. Lstiburek is one of the world’s foremost authorities on energy efficient construction techniques and heads one of the Building America program teams for the U.S. Department of Energy. Through the program, Dr. Lstiburek has forged partnerships with designers, builders, developers, materials suppliers and equipment manufacturers to build higher performance buildings across the U.S.

Dr. Lstiburek is a noted educator who has taught hundreds of professionals over the past three decades. He has written numerous books and technical papers on building science, indoor air quality and durability, such as the best-selling Builder’s Guides and the U.S. DOE Handbook on Moisture Control. Fittingly, the Wall Street Journal has described him as “the dean of North American building science.”
