Comment la résilience est-elle prise en compte dans les exigences du code du bâtiment?

Les mises à jour des codes du bâtiment sont généralement adoptées lentement à travers les États-Unis. D’un État à l’autre, les constructeurs suivent souvent des codes différents en fonction de la date à laquelle les mises à jour de code dans leur région ont été mises en œuvre. Cela signifie qu’il appartient à chaque constructeur de déterminer dans quelle mesure il suivra les meilleures pratiques de l’industrie.

Building with resilient materials is among the industry's top concerns, and it's beginning to factor into building code requirements and development. This shows that taking measures for increased resiliency may soon be a requirement, not only a best practice. Let's take a look at this trend, how codes and resiliency connect, and how the LP® Structural Solutions portfolio can help builders meet code while contributing to a more resilient build.

What Is Resiliency and Why Does It Matter?

The AIA's Industry Statement on Resilience defines resiliency as "the ability to prepare and plan for, absorb, recover from, and more successfully adapt to adverse events." According to the National Oceanic and Atmospheric Administration (NOAA), billion-dollar weather disasters have increased over time, with 338 in total since 1980 and 56 in the past three years alone.

Beyond typical weather, moisture and energy concerns, resiliency is a critical issue in light of high-risk natural disasters—both in terms of the financial resources it takes to rebuild and the growing threat to the people who live in certain areas of the country.

When the industry prioritizes building with resilient materials, the impact reaches beyond a single home—we're contributing to our purpose of Building a Better World™, helping to create a safe, secure place for people to call home.

How Can Building Code Requirements Contribute to More Resilient Structures?

First of all, why are building codes important?

In a whitepaper by the International Code Council®, the organization notes that “building codes are an essential strategy in achieving resilience. [They] provide minimum requirements to protect life-safety in the built environment—every day and particularly in the face of hazards.”

“Resiliency becomes more about building scientists identifying problems and offering solutions,” says Neil Freidberg, Building Science Manager at LP Building Solutions.

Importantly, resiliency can be achieved when codes are coordinated across different threats, such as moisture, fire, durability, energy efficiency and more. "A product can be resilient in itself, but we want to talk about the building as a whole being resilient-not just a single component," says Freidberg. "It's a systems approach, and LP has products for all systems."

Despite code updates that lean into building with resilient materials, code adoption varies among states. "Typically, it takes 5-6 years from when a new building code requirement is published to full adoption," Freidberg says. "Some will still allow variances from the latest code so they fall back to previous codes."

Though they can always build beyond building code requirements, builders may choose to stick to what they know and what makes the most financial sense before fully adopting a new requirement—thus creating a wide range of resiliency throughout the country.

Building With Resilient Materials That Meet Code

LP Structural Solutions products can help builders meet code requirements, no matter where a build is located, and still boost their structure's resiliency. For example, LP® FlameBlock® Fire-Rated Sheathing helps builders meet code for fire-resistant construction while adding structural strength and retaining design flexibility. LP WeatherLogic® Air & Water Barrier can serve as part of a wall assembly designed for strength and for moisture resistance. 

The Bigger Picture: A More Sustainable World

At LP, everything we do ladders up to our core purpose: Building a Better World™. Ultimately, resiliency isn't just about avoiding costly rebuilds-it's about sustaining the people around us and communities in which they live.

Resilience plays a key role in vulnerable communities where extended impacts of severe weather can take a significant toll. That's why structural resiliency is just one piece of the puzzle-but it's one we take seriously.

Building to address specific types of weather and location can help you decide what products to use. As building code requirements skew stricter with an intent to bolster resiliency, building professionals can help lead the way with quick adoption and shifting to premium products designed to help them build better.
