NAHB’s Eye on Housing blog examined the emergency and disaster preparedness of U.S. households based on the results of a special set of questions in the 2013 American Housing Survey. “NAHB tabulations of the survey found that 86.2% of owner-occupied households reported having enough non-perishable food to sustain everyone in the household for three days,” the blog post notes. When it comes to water, 57.7% had access to at least three gallons or 24 bottles of water for each person in the house. Those and other preparedness statistics are notable as construction professionals and the public become increasingly aware of the resilience of the built environment. A whole-house resilience strategy may include not only a propane-fueled backup generator, but also fuel sources and heating systems that can operate even during a grid outage.
