Mass walls in combination with insulation can save energy in buildings. This presentation describes the benefits of thermal mass (thermal inertia) and how these benefits are recognized in national energy codes. An overview of compliance paths of these energy codes is presented. The degradation of the R-value of concrete panels with metal thermal bridges that pass through the insulation is also described.
Learning Objectives ~ Attendees will:
Identify why mass walls save energy.
Learn the heat capacity requirements for mass walls in energy codes.
Determine how thermal mass provisions are presented in national energy codes.
Learn how metal thermal bridges that penetrate the insulation in a mass wall degrade its R-value.
