Wood’s favorable carbon footprint is one reason more North American architects are choosing wood-frame construction for buildings up to six stories while closely following the rise of taller wood buildings made from mass timber and hybrid buildings. However, while it is fairly well known that wood products sequester carbon and typically require less energy to manufacture than other building materials, their performance related to operational energy efficiency is often overlooked.

Learning Objectives – After this course, you should be able to:

  1. Summarize a range of design considerations required to achieve energy-efficient building enclosures in multi-story wood-frame buildings.
  2. Discuss thermal insulation strategies, which must be considered together with airtightness and vapor permeability in assemblies in order to achieve effective thermal efficiency.
  3. Explain common methods for controlling heat and airflow in wood-frame buildings.
  4. Identify how new energy codes, such as the International Energy Conservation Code, have placed increased emphasis on the thermal performance of buildings.
