This session discusses thermodynamics and the laws of heat transfer and the application of these concepts to buildings to show how, where, and why heat flows through walls. Topics addressed include Fourier's Law, R-values and insulation, windows and fenestration, infiltration, control layers, and commissioning. 

Course expires 03/05/2025

Learning Objectives


Explain how heat travels from higher temperatures to lower temperatures using Fourier's Law


Understand and describe the methods of heat transfer (conduction, convection, and radiation), and how a well-designed building envelope optimizes each of these to create a comfortable indoor environment


Discuss the different types of insulation, windows, and wall construction materials and their impacts on the final R-value of a wall


Define infiltration and exfiltration and discuss commissioning procedures used to pinpoint areas of air leakage in a building
