Imagine a building resilient enough to allow people to continue their daily tasks even while an emergency is in progress. The self-reliant building might have its own small electrical generating system to maintain lights, computers, and mobile communications during a power outage, compartmentalized clusters of rooms to prevent water damage in one sector from affecting others, shatterproof windows to minimize hazards from imploding glass and sufficient electronics to quickly pinpoint a trouble spot.
For obvious reasons, increased resilience for buildings in the face of hurricanes, earthquakes, terrorism, or cyberattacks has been a major national security focus over the past decade. Such resilient buildings not only would be less susceptible to damage and work interruption but could become community gathering places in a general crisis, according to a recently published Sandia paper, “Resilience certification for commercial buildings: A study of stakeholder perspectives,” published in Environment Systems & Decisions, where Sandia researcher and lead author Barbara Jennings proposes five concepts to help the concept of resilient buildings appeal to the construction, design and insurance communities, and to building owners.
But it won’t be easy to secure voluntary adoption by industry and builders without adequate justification, explains Jennings. Expecting industry to act, for example, merely because “it’s the right thing to do” came out lowest (3 votes on a 1-to-10 scale) in a questionnaire presented to 15 industry representatives. The highest number of respondents were motivated by economics. Their justifications included increased revenue (10 votes), better competitive edge (9) and quicker, cheaper recoveries (9) from more efficiently handling a disruption. Several others cited “decreased insurance premiums” (8) and “tax incentives” (7), while fewer respondents pointed to less obvious benefits: “Increased chance of receiving financing or lower finance rates” and “ability to charge higher lease rates due to increased attractiveness of the building to tenants” (both 5).
The Department of Homeland Security’s Office of Policy funded the work.
