In recent years, “net-zero” has become one of architecture’s most recognizable sustainability benchmarks. The goal is admirable: buildings that produce as much energy as they consume over the course of a year. But as climate events become more severe and infrastructure systems more vulnerable, another concept deserves greater attention: passive survivability.

For decades, flood-resistant architecture was often treated as a specialized concern—primarily relevant to coastal regions or isolated high-risk zones. Today, that distinction is rapidly disappearing. Floodplain design is no longer niche resiliency planning; it is becoming a mainstream architectural necessity.
