Daniel J. Lemieux

Experience

Since joining WJE in 1996, Daniel Lemieux has successfully completed hundreds of projects in building enclosure failure investigation, repair design, and architectural rehabilitation, including projects that have been recognized nationally for design and restoration excellence. As the firm’s Director of International Development, he is responsible for advancing WJE’s global architecture and building science practices. Prior to that, Mr. Lemieux served as managing principal of WJE’s Washington, D.C. office from 2005 to 2016.

Mr. Lemieux currently serves on multiple ASTM International committees, including vice chair of E06, Performance of Buildings and chair of E06.55, Performance of Building Enclosures. He is founding chair and a primary author of ASTM E2813, Standard Practice for Building Enclosure Commissioning (BECx) and worked closely with WJE colleagues and practicing and teaching professionals from across North America to support the development of ASTM E2813; ASTM E2947, Standard Guide for Building Enclosure Commissioning (BECx); and ASHRAE Standard 202, Commissioning Process for Buildings and Systems. He served as an author and technical editor for the National Institute of Building Sciences’ (NIBS) web-based Whole Building Design Guide and NIBS Guideline 3: Exterior Enclosure Technical Requirements for the Commissioning Process.

Mr. Lemieux has developed, chaired, and been invited to speak at multiple workshops and symposia on building science and the physics of building enclosure performance in North America, the UK, EU, UAE, and China and has cochaired the Symposium on Building Physics and Conservation with Historic England and Historic Environment Scotland in London.

Since the tragedy at Grenfell Tower, Mr. Lemieux was invited to assess proposed regulatory reforms in the UK in response to the fire and continues to work closely with WJE’s fire and life safety practice on this topic through committee work with the Society of Fire Protection Engineers Europe.
