About the Series

This four-part series explores the overall satisfactory performance of the building envelope as far as airtightness is concerned. It incorporates a holistic perspective towards achieving airtightness, taking into account other performance aspects such as long-term durability, thermal comfort, moisture management, energy efficiency, adaptability to future repair and renovation, cost, etc. 

A highly interactive and collaborative format is used with the goal to make the sessions as rewarding as possible. Each session is supported by forty mobile building envelope assembly mock-ups, a wide range of air barrier products and systems, an intuitive and easy to follow PowerPoint presentation, various interesting and practical case studies, photographs, and 3D drawings. In addition, several brainstorming sessions, group works, and demonstrations are incorporated with the goal to create a vibrant and energetic environment in support of the learning experience of the attendees. By embracing the holistic perspective, this four-part series encourages the industry towards the implementation of high-performance building practices.

The main focus of this four-part series is on wood-framed construction (Part 3 and Part 9), although the key lessons will be equality applicable to other types of construction such as concrete and steel-framed buildings. Each part will focus on specific assemblies listed below, and then in the final part, all the learnings will be integrated into developing complete sets of building envelope details for an example building.

Session 1: Sloped Roofs, Flat Roofs, Decks
Session 2: Above Grade Walls, Below Grade Walls and Slabs
Session 3: Windows, Doors, and Curtain Walls
Session 4: Putting it all together
