This 2-day Efficient Building Envelope (EBE) course introduces the concept of a building as a system, and takes an in-depth look at the interrelationship between the building envelope and installed mechanical sub-systems. The course will examine the principals of heat loss/gain through the envelope (wall, roof, floor and fenestration), and explore the interactions with equipment and occupants.


The importance of air tightness, thermal bridging, and moisture control will be discussed in detail using a variety of typical commercial construction types, with heavy focus placed on designing efficient and durable assemblies. Finally, participants will gain insight on the three compliance pathways available to Part 3 buildings under the newly revised National Energy Code of Canada for Buildings (NECB 2011).
