The race to codify resilience design

An array of guidelines and standards coming from all kinds of sources are jockeying for position to stamp their imprint on resilience best practices and, potentially, new codes.

Last November, the International Code Council launched the Alliance for National & Community Resilience for the purpose of developing a whole community benchmark rating system by 2018. The alliance’s members include such heavy hitters as Target and Kaiser Permanente.

Two months earlier, the American Society of Landscape Architects launched an online guide for resilient landscape planning and design to help communities protect themselves from natural disasters. Nancy Somerville, the trade group’s CEO, says ASLA convened a panel of experts—including scientists, policy makers, and landscape architects—to produce policy recommendations that ASLA intends to release sometime next year.

These are examples of an array of guidelines and standards coming from all kinds of sources that are jockeying for position to stamp their imprint on resilience best practices and, potentially, new codes.

“There are an increasing number of standards around resilience that AEC firms need to be prepared for,” says Katharine Burgess, Senior Director of Urban Resilience with the Urban Land Institute. ULI is providing resilience assistance to cities, communities, and its members through a variety of programs.

BREEAM and the Institute for Sustainable Infrastructure are working on resiliency standards. The American Society of Civil Engineers is crafting standards for adaptive redesign. The Insurance Institute of Business and Home Safety recently launched a rating system, Fortified Commercial, as a companion to its Fortified Home standard. IBHS has written full sets of standards for construction in markets susceptible to hurricanes, high winds, and hail.

Some AEC firms use their own resilience measurement tools. Arup created a framework and rating system for designing earthquake-resilient buildings which it calls Resilience-based Earthquake Design Initiative, or REDi.

Several cities, states, and the federal government either have their own resilience guidelines or are developing them. Degenkolb Engineers has been helping California create seismic retrofit ordinances for various building typologies.

Erica Fischer, PhD, PE, a former Design Engineer with Degenkolb who is now an Assistant Professor at Oregon State University, says these revisions set timelines for buildings to be evaluated and retrofitted. If the owner doesn’t comply, a notice gets posted on the building stating that it doesn’t meet seismic standards.

In November 2015, the U.S. Green Building Council launched a pilot program for resilient construction, with three LEED credits. USGBC ended the program after a year, but the organization’s Resilience Working Group has been attempting to revamp the credits system. Alex Wilson of the Resilient Design Institute, which spearheaded the pilot, says RDI has resubmitted its proposal. He suggests USGBC might be ready to introduce a new resilience credit program at Greenbuild in Boston this November. USGBC’s spokesperson Marisa Long says the council hasn’t set a timetable for the release.
