This course discusses some basic building science fundamentals, while looking at specific code requirements in the IRC, IBC and the international energy conservation code. It addresses why some of the trade-offs and differences exist between those two sets of code requirements. Lastly, we'll work through an example and the decision making process to determine the continuous insulation and vapor retarder requirements for a project in a specific climate zone.

Learning Objectives

  • Explain the concept of thermal bridging and how it impacts building energy usage.
  • Define the commercial and residential wood-framed wall insulation requirements found in the 2015 International Energy Conservation Code (IECC).
  • Discuss how condensation forms in wall cavities, and investigate strategies to mitigate risk of damage to construction, while promoting healthy indoor environments.
  • Compare green or sustainable building characteristics of various continuous insulation alternatives as part of the exterior wall assembly.
