A Holistic Approach Towards Improved Air Tightness (Building Better Buildings Full-Day Seminar)

Event date: May 23, 2019
Showtime: 8:00am - 5:00pm
Location: Delta Hotels Burnaby Conference Centre (4331 Dominion Street Burnaby, British Columbia)
8 CPD points in Group A


The Homebuilders’ Association Vancouver (HAVAN) is proud to present our spring full-day Building Better Buildings Seminar – A Holistic Approach Towards Improving Air Tightness with Hamid Heidarali of Hamid Design Build on Thursday, May 23. This full-day seminar will provide builders, architects, designers and renovators with a holistic approach to improving air tightness in high-performance buildings.

Popular guest speaker Hamid Heidarali, will lead the in-depth and interactive hands-on workshop to provide the industry attendees with a holistic perspective of the overall performance of the building envelope in terms of air tightness. Supported by 30 mobile building envelope assembly mock-ups, the workshop will showcase various methods of improving air tightness of wood, concrete, and steel-framed buildings.

The workshop will also demonstrate how the presented methods will have an impact on moisture management, energy efficiency, and thermal comfort. In addition, all presented air barrier methods will be explored and reviewed in relation to long-term durability, adaptability to future repair and renovation. With the focus on delivering hands-on and interactive learning, this workshop will prepare the industry for the adoption of BC Energy Step Code.

Presented with much acclaim in other areas of the province, Hamid will be tailoring the content to the Metro Vancouver market, providing extensive research-based information and case studies to walk builders through the wide range of methodologies to improve air tightness.
