Evolving Climate Patterns and Extreme Weather Demand New Building Methods

May 22, 2023 — Annette Rubin - Construction Executive
Compared to the rest of the world, most buildings in the United States are relatively young. But most residential and commercial properties could use a makeover. Buildings constructed over twenty, fifty and one hundred years ago are, unsurprisingly, not as energy-efficient or as safe as new builds following modern methods—especially when considering the effects of climate change and more frequent extreme weather events on the integrity of that infrastructure. According to the National Association of Home Builders, over 90% of new homes built in the United States today are wood-framed. These homes are incapable of withstanding a tornado or hurricane, yet they are still being built directly in the path of storms. Even buildings constructed in some of the most earthquake-prone areas of the U.S. may contain design flaws that make them susceptible to damage because they are built using a non-ductile concrete method, which experts say has an inadequate configuration of steel reinforcing bars—making the building vulnerable when shaken. While this building method was banned for new construction, it is not yet required to retrofit older construction to improve safety and structural integrity.
