Mark Van Dalen, P.Eng,
Business Development Leader for UL CLEB’s Advisory Services business
 
Mark is a professional engineer with a thirty year career in the field of building envelope consulting.  For twenty years he ran an Ottawa-based firm he founded to offer consultation on the design and performance of commercial building envelope systems.  In 2013 the activities of his firm were taken over by CLEB and Mark assumed the role of Vice-President for Consulting Services in Ontario and Atlantic Canada.  Earlier this year, CLEB was acquired by UL and Mark transitioned to his current role. Mark's experience includes investigation of envelope failures as well as commissioning of new envelope construction. His experience also encompasses a wide range of envelope systems, including vertical and sloped glazing on several landmark, unique buildings such as the National Gallery of Canada and the Bank of Canada Headquarters.
 
 
In the 1970’s three sides of the original 1930’s Bank of Canada Headquarters building was surrounded by two small towers and an Atrium.  The newer construction was entirely metal and glass curtain wall with very distinct characteristics designed by Arthur Erickson.  After years of performance problems with the curtain wall assemblies, the modernization of the complex presented the opportunity to address the long standing concerns with the walls as well as to establish a higher level of performance for the next service cycle.  This presentation will explain the primary objectives and solutions adopted for the remediation of the curtain wall systems enclosing the Headquarters.
