What if stronger building codes don't make homes more expensive?
What if America's oversized homes aren't really about excess—but about uncertainty?
And what will happen if states or municipalities try to give AI data centers the heave-ho?
These questions and more are answered in This Week's Sustainable Building News:
Let’s begin with groundbreaking research from the University of Alabama that examined 2.7 million home sales across 26 states and found no evidence that modern building codes increase home sale prices. The findings challenge one of the most common arguments against adopting stronger codes while reinforcing the long-term value of resilient construction.
From there, we explore a provocative new perspective from Green Builder magazine Editor-in-Chief Matt Power. Why are American homes so much larger than homes in countries like Sweden or Norway? His answer may surprise you: perhaps our homes have become our safety net. It's a thought-provoking look at the relationship between housing, security, and sustainability.
We also take a closer look at the rapidly expanding world of AI infrastructure. The EPA has proposed changes affecting air permits for backup generators at data centers, while New York has become the first state to temporarily pause new hyperscale facilities. As communities across the country grapple with questions about electricity demand, water use, and environmental impacts, the AI boom is becoming a housing and infrastructure story as much as a technology story.
In the states, Seattle is making accessory dwelling units easier to build, including allowing 2 unattached ADUs on a lot in addition to the primary home. Texas adopted the 2024 Uniform Mechanical Code. And take a visit to Lagoon Valley, California's pioneering conservation community, in the latest episode of The Valuation Metric.
A new report warns that water shortages in the Colorado River Basin could affect future housing and commercial development across the Southwest. Follow the plans to fix this urgent problem, including three summits that will discuss options.
And, of course, a little sustainable eye candy—a breathtaking marsh-side Florida home by Richard Pedranti Architects, which proves high-performance, resilience, and beauty can go hand in hand.
