Designers, professionals and building owners are committed to ensuring the energy performance of buildings. Obviously, nobody would want the energy used to heat or cool a building to be lost, whether because of poor thermal insulation or assemblies that allow air infiltration and exfiltration.
Building codes require that we consider the performance of assemblies and that of buildings in general. There are many requirements regarding the amount of insulation in different areas in buildings, but also for the energy consumption of all kinds of products used in buildings.
The purpose of this presentation is to demonstrate the winning ways to increase the energy performance of exterior wall assemblies.
It will help answer the following questions, among others: How do we assess the overall performance of exterior wall assemblies? How much insulation should be used? What is the impact of using continuous exterior insulation?
Learning Objectives
Understand the difference between U‑value, R‑value and effective R‑value
Differentiate the types of exterior wall assemblies and the impact of thermal bridges on their overall relative thermal performance
Understand the impact of incremental insulation on the effective thermal performance of various types of assemblies
