Advanced Building Envelopes Simplified: Four Control Layers
Date: May 15, 2019
Presenter: Kathleen Narbonne
Learning Units: 1 hour
This is a recording of a live webinar.
Undoubtedly, high-performance wall assemblies are required in order to achieve increased energy efficiency and reduced operational carbon in buildings. But before we look at advanced building envelopes, we need to understand the components that make up a wall assembly and how those components function in order to keep the outside out and the inside dry. We call these components the four control layers (weather, air, vapour and thermal). These control layers are required for every wall assembly but can become confusing when working with advanced wall assemblies. It is important that we understand these control layers in depth in order to design high-performance wall assemblies that function as they are intended. This session will focus on defining and identifying the four control layers and provide examples of these layers within four different advanced wall assemblies.
