1 AIA LU/HSW; 1 GBCI CE Hour; 1 AIBD P-CE; 0.1 IACET CEU*; SAA 1 Hour of Core Learning

Learning Objectives:

  1. Discuss the thermal advantages of building with wood.
  2. Describe how designing with wood can enable design flexibility to maximize building performance.
  3. Explain common methods for controlling heat and airflow in wood-frame and mass timber buildings.
  4. List common insulation, airtightness, and vapor permeability strategies often employed with wood construction to achieve effective thermal efficiency.

Conclusion

The inherent properties of wood include strength, durability, sustainability, and flexible design options, which allow architects to design commercial and nonresidential buildings to a higher level of thermal performance. Compared to other building materials, choosing wood framing, both light frame and mass timber, leverages the natural attributes of wood and provides for accessible code compliance and energy savings. Whether choosing light frame design or leveraging the advantages of mass timber products, wood continues to provide economic, structural, and environmentally efficient benefits to designer, builders, and occupants.
