The Influence of Energy Codes in the Evolution of Building Enclosure Design

Building energy design has progressed in recent years and it is important to assess where we currently are and where we are headed in the future.

In this session, we explore how the building envelope evaluations differ and what new challenges and opportunities will surface as energy codes rise. To avoid enclosure failures, understanding how building materials perform as a system is imperative, this presentation will also review building science fundamentals as they relate to thermal and moisture control and will outline a hybrid roof strategy and the benefits of combining insulation types as a cost-effective choice for roof applications.

Finally, we will discuss the project design of StudioBell and the challenges curved walls presented while reviewing the wall assembly used to overcome these issues.

Learning Objectives:

  1. Review the history, scope and local mandated energy requirements of the National Energy Code of Canada and their impact on building enclosure design strategies.
  2. Understand key building science principles related to the building enclosure and examine stone wool solutions that meet and exceed code requirements.
  3. Discuss the function and performance of hybrid stone wool roof solutions in local projects.
  4. Recognize key elements in the execution of high-performance buildings based on learnings from local projects.
