56CE - Building Envelope Commissioning - Design into Reality

09 May 2014 10:30 AM to 12:00 PM

1.5 ConEd Learning Hours

This session will also be offered Friday, May 9, 2014 8:30 AM - 10:00 PM

Course Outline

A discussion of the Building Envelope Commissioning process and how it applies to successful environmental separation design and construction will be presented. The theory will be coupled with a case-study example to demonstrate the real benefits to a large and successful project. BECx is becoming a key function in the translation of design intent into construction reality. Coupling an owner's requirements with a designer's intent, and then closely monitoring the construction delivery is a vital consideration for the success of any project. The continued expansion of energy, durability and operational performance requirements, and the sophistication of new envelope technologies suggests that a formal envelope commissioning process can add enormous benefits to all stakeholders.

This presentation will look into how a formal BECx process should be developed compared to a well-integrated process assisted with the delivery of a successful outcome on the case study project.

Learning Objectives:

  1. Understanding of the Building Envelope Commissioning process
  2. How BECx can provide higher levels of risk management for the delivery of a project
  3. How adoption of a full BECx process will help the Architectural design team achieve its goals and objectives for the project
  4. Understanding of the value of various building envelope design and construction techniques to monitor and improve specific desired project outcomes


David Kayll FMA, P.Eng (ON, NS, NB, NL)
David is a principal of Morrison Hershfield and a professional engineer specializing in building science and building envelope, based in the Ottawa office. His main areas of practice include building envelope / enclosure issues, building envelope commissioning, building science analysis and design and facility management consulting for both new and existing facilities.

David worked for Morrison Hershfield in the Vancouver office from 1999 to 2003, where he became immersed in the repair of “Leaky Condo” buildings, diagnosing causes of failures and assisting with repair or replacement strategies. From 2003 to the present, David has worked in the Ottawa office covering a broad range of projects including heritage building restoration, new building design, failed building envelope rehabilitation and energy performance evaluation. Projects have ranged from Manitoba to Baffin Island to Newfoundland. 

He and his colleagues are well respected for their knowledgeable, pragmatic and effective approach to addressing building envelope issues, whether involved in the initial design to achieve Code compliance performance, achievement of the LEED credit for Durability or in assessing failures and recommending repairs. 

He is a member of the National Building Code’s Standing Committee on Environmental Separation (NBC Part 5) and is actively involved on a number of the Task Groups of the Committee.

In addition, David has assisted Pro-Demnity Insurance Company on assignments aimed at assisting architects avoid claims stemming from envelope failure.
