Join us for a special two-hour meeting as we welcome David Kayll, FMA, P. Eng.

The effective thermal resistance of building enclosure assemblies is essential information when evaluating the overall thermal performance - for more accurate energy modeling and for better understanding of how and where money should be spent to provide a better building design. As energy codes continue to request better performance and lower energy use, knowledge of how a building enclosure actually manages heat flow becomes critical.

  • Understand the disconnect between actual building envelope performance versus theoretical assumed performance
  • Quantify the impact of thermal bridging in the context of effective R-values and whole building energy performance
  • Show how thermal bridging can be mitigated and compare to other energy efficient measures
  • Become familiar with the cost impacts

David Kayll, FMA, P.Eng., Principal – Morrison Hershfield. David is a building science specialist engineer with over 27 years’ of experience, located in Morrison Hershfield’s Ottawa, Canada office. He provides professional expertise in building science, building enclosure design and commissioning, and facility management consulting. His background includes engineering consulting to public and private organizations, specialist support to building designers, and design on renovation and new construction.

David has worked in building science across Canada and the US, including Canada’s Far North, and on both the Pacific and Atlantic Coasts. He has completed building condition audits, building envelope problem investigation, new and rehabilitation building envelope design, energy systems analysis and integration, field assessment and testing, expert opinion, and facility/property management consulting. He is a member of the Canadian National Codes Committee Standing Committee on Environmental Separation, and he has been an active member of Building Enclosure/Envelope Councils in both Vancouver and Ottawa.

BEC: Austin is an interdisciplinary organization that promotes the exchange of information on building enclosures and related science specific to the climate of Central Texas.

Interdisciplinary:  architects, engineers, contractors, building owners, consultants, facility managers, code officials, educators, manufacturers, and those with a stake in building enclosure performance

Exchange of information:  discussion, training, education, outreach, and awareness

Building enclosures and related science:  energy-efficiency, moisture control, indoor air quality, longevity, and durability

BEC: Austin typically meets the first Wednesday of each month from 12-1pm.
