Daniel J. Lemieux

Experience

Since joining WJE in 1996, Daniel Lemieux has successfully completed hundreds of projects in the area of building enclosure failure investigation, repair design, and architectural rehabilitation. Since 2016, he has served as Director of International Development, responsible for advancing WJE’s global architecture and building science practices. Before that, Mr. Lemieux served as managing principal of WJE’s Washington, D.C. office from 2006 to 2016.

In 2017, Mr. Lemieux helped lead the establishment of Wiss, Janney, Elstner Limited, London. After the tragedy at Grenfell Tower, he was invited to provide input on proposed regulatory reforms in response to that fire and worked closely with WJE’s fire protection group to educate building owners, investors, design professionals, and contractors about the causes of that tragedy. 

In 2021, Mr. Lemieux was elevated by a jury of his peers to the AIA College of Fellows for his work in building science and the physics of building enclosures and whole building performance. He has authored, coauthored, presented, and chaired workshops and symposia on that topic in North America and internationally and served as co-chair of the 2017 Symposium on Building Science and Conservation at Southbank Centre, London.

In 2024, Mr. Lemieux was invited and served as a part-time practicing professor at the Georgia Institute of Technology responsible for developing and leading a graduate-level course in Failures & Forensics in Our Built Environment and was invited to develop a similar course for the College of Engineering at Purdue University in 2025.

Mr. Lemieux currently serves as chair of ASTM Committee E06 - Performance of Buildings and is past chair of Subcommittee E06.55 - Performance of Building Enclosures and the Task Group responsible for developing ASTM E2813, Standard Practice for Building Enclosure Commissioning (BECx) and ASTM E2947 Standard Guide for BECx. He is a member of the CISE Industry Advisory Board for the College of Civil and Environmental Engineering at Georgia Tech and Myers-Lawson School of Building & Construction Science at Virginia Tech.
