Daniel J. Lemieux

Principal and Director of International Operations

 
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, including projects that have been recognized both locally and nationally for design and restoration excellence. In October 2005, Mr. Lemieux assumed management responsibility for the Washington, D.C. office of WJE, responsible for the continued development and expansion of that practice until January 2016, when he joined the International Operations group as Director, responsible for advancing our global practice in architecture and building science.

As a building enclosure specialist, Mr. Lemieux has authored, coauthored, and served as technical editor for the National Institute of Building Sciences (NIBS) during its initial development of NIBS Guideline 3: Exterior Enclosure Technical Requirements for the Commissioning Process. He currently serves as vice chair of ASTM Committee E06, Performance of Buildings; chair of ASTM Subcommittee E06.55, Performance of Building Enclosures, and is founding chair and a primary author of ASTM E2813, Standard Practice for Building Enclosure Commissioning (BECx). As ASTM chair, Mr. Lemieux worked closely with colleagues from WJE and peer-level practicing and teaching professionals from across the U.S. and Canada to support the development of ASTM E2813 and ASTM E2947 together with the establishment of a Memorandum of Agreement between ASTM and NIBS to work together to further advance our understanding of building science and the physics of building enclosure and whole-building performance.

In 2011–2012, Mr. Lemieux supported our post-earthquake assessment and repair design for the Washington Monument and Washington National Cathedral as contributing architect to the WJE team and technical liaison to the Public Information Office of the U.S. National Park Service, responsible for responding to technical inquiries from local, national, and international broadcast and print media.
