The Future of Sustainable, Resilient Design

Based on their Top 100 Green Design Firms insights, ENR reports that green design revenue increased 7.8% from 2023 to 2024. Despite regulatory challenges, many people remain optimistic about the impact of sustainable projects, including Will Wilhelm, director of sustainability and resiliency consulting at Kimley-Horn, who was quoted in ENR’s feature article on the Top 100 Green Design Firms.

“Challenges [with sustainable design] can transform into long-term value for clients, especially as increasing extreme weather events underscore the urgency for sustainable development and infrastructure. Lasting progress depends on engineering and design professionals shifting their mindsets to fully consider downstream risks—both temporal and spatial—so that decisions made about the built environment and infrastructure result in a 30-100-year lifespan and beyond.”
