GB300 – Development of Wood Products LCA Data and Its Usage in Green Building Codes

PDF YouTube SelfStudy Subjects

There are three approaches referenced in the ICC 700 National Green Building Standard that allow for life cycle analysis (LCA) of products, built-up assemblies, or entire structures. AWC has completed sample LCAs for comparison of wood studs to steel studs using the National Institute of Standards and Technology’s (NIST) Building for Environmental and Economic Sustainability (BEES) program, as well as an LCA for an insulated wood stud wall assembly using Athena’s Impact Estimator. A whole building LCA will be conducted using REVIT software.

Level: Beginner
Primary Audience: Engineers, Code Officials, Others

Learning Objectives:

  1. Learn what Life Cycle Assessment (LCA) is and how it is used to develop Environmental Product Declarations (EPD).
  2. Learn about EPDs developed by the American Wood Council (AWC) and Canadian Wood Council (CWC) and how to use them in green building codes.
  3. Learn how to apply LCA to earn credits in the National Green Building Standard (NGBS).
  4. Discern differences in acceptable types of LCA in NGBS.
  5. Learn about some of the software programs that are currently acceptable for LCA.
