People who don’t know, don’t know that they don’t know.  Discussion of issues in the industry where we don’t have the research and information on what is being done about it.  We all want to have our buildings perform and we need better ways of determining how to address issue of air leakage and water intrusion into the building envelope.  The presentation will cover research projects that have been done and projects that are on the list to do..


  1. Determine the reason for conducting pull adhesion tests in the field
  2. Show why detecting water inside the building is the wrong approach
  3. Explain why you cannot look at a single control layer to solve a problem
  4. List some of the problems building designers will face in the near future


Mr. Laverne Dalgleish has been actively involved in the construction industry for over 35 years and has specialized in building envelopes, energy efficiency and building performance for both commercial and residential construction.

Starting as a builder in the 1970’s, Laverne constructed some of the most energy efficient houses in North America, including houses that were Net Zero ready with a focus on high levels of airtightness and insulation.

Since then, he has championed to transform the building industry to raise the bar in professionalism for building trades and focus on quality processes in construction to ensure long-term high performance buildings.

Over the years, Laverne has become a frequent presenter across North America on a variety of topics as they relate to building envelopes, energy efficiency, green building practices, and standards and quality of construction.

Laverne is actively involved in the standards development process and has been involved with International Organization of Standardization (ISO) for over two decades, travelling around the world and creating development standards for the industry.  A big believer in scientific research, Laverne has been a leader and participated in a number of commercial and residential building research projects with groups such as Oak Ridge National Laboratories, Syracuse University, University of Waterloo and the National Research Council of Canada.  Laverne has been involved in a number of utility demand side management programs and worked with various government departments across North American such as the U.S Department of Energy, Natural Resources Canada, Environmental Protection Agency, Environment Canada and Canada Mortgage and Housing Corporation.
