1 AIA LU/HSW; 1 GBCI CE Hour; 0.1 IACET CEU*; 1 PDH*

Learning Objectives:

  1. Discuss why the concept of resilience can be viewed as another step in the evolution of sustainable building design.
  2. Identify the strengths of traditional wood framing and mass timber systems in the context of building resilience, including performance during and after earthquakes, hurricanes, and other disasters, as well as the relevance of carbon footprint and embodied energy.
  3. Explain how the International Building Code (IBC) and referenced standards such as the National Design Specification® (NDS®) for Wood Construction support building resilience.
  4. Describe examples of research related to the development of new building materials and systems that could help communities meet more stringent resilience criteria.

Government and Private Initiatives

The concept of resilience has gained sufficient momentum that it is now encouraged to varying degrees through federal, state, and local government policy, and through numerous private initiatives.

Prior to the recent Earthquake Resilience Summit, for example, the federal government issued an executive order establishing a Federal Earthquake Risk Standard, which calls for new, leased, and regulated federal buildings to meet seismic safety provisions outlined in the IBC and International Residential Code (IRC).

“There is no more important contributor to reducing communities’ risks from earthquakes than the adoption and application of modern building codes and standards,” said ICC Chief Executive Officer Dominic Sims, CBO. “To survive and remain resilient, and to assure the rapid recovery of local economies, communities must employ the most up-to-date code provisions. This executive order ensures that federal facilities and their occupants will be safe when the next earthquake strikes.”

The ICC works collaboratively with NIBS and ASCE to translate National Earthquake Hazards Reduction Program provisions into the IBC. The Council’s three-year code development cycle incorporates the most up-to-date science and technology for seismic safety for broad use by designers, contractors, manufacturers, and code officials. The executive order calls for federal agencies to comply with the provisions of updated versions of the IBC and IRC within two years of their release.

The ICC is also a founding member of the US Resiliency Council (USRC), along with organizations such as the National Council of Structural Engineers Associations (NCSEA), engineering and architecture firms, industry representatives, and individuals. Created to establish rating systems for the performance of buildings during natural hazard events, the USRC recently launched an Earthquake Building Rating System, which measures expected building safety, damage, and recovery time for buildings subject to earthquake forces.

Resilience is also being encouraged through green building certification systems.

The U.S. Green Building Council recently added three pilot credits to the LEED program related to assessment and planning for resilience, designing for enhanced resilience, and passive survivability and functionality during emergencies.

“Resilience is becoming a major focus for governments and communities,” said Vicki Worden, executive director of the Green Building Initiative, which oversees the Green Globes rating system. “Green building has always included a focus on resilience. It’s just taking more explicit shape. Concern about changing climates is leading to promotion of integrated design processes. This encourages community input, site selection that considers regional climatic impacts, materials selection through use of life-cycle assessment and building service life analyses, life-cycle cost analyses, and moisture control analyses.” GBI also recently updated its Mission & Principles to include resilience.
