U-Net-Accelerated Quality-Diversity Optimization for Climate-Adaptive Urban Layouts

arXiv:2606.04658v1 Announce Type: cross Abstract: Optimizing urban layouts for climate adaptation requires balancing building density with cold-air ventilation. Because physics-based climate simulations are computationally expensive, planners typically evaluate fewer than ten manual designs. \gls{qd} algorithms offer a way to systematically illuminate the design space, but they require surrogate models to be practical. In this paper, we replace a slow, regulatory physics simulator with a spatial deep-learning surrogate (U-Net) inside an offline MAP-Elites loop. We systematically compare this s

Why this matters
Why now

The increasing computational power of AI, specifically deep learning surrogates, is enabling more complex and efficient urban planning solutions for climate adaptation, addressing an urgent global need.

Why it’s important

This development allows for the systematic optimization of climate-adaptive urban layouts, moving beyond manual designs to significantly enhance urban resilience and resource efficiency in the face of climate change.

What changes

Urban planning can now leverage AI-powered predictive models to rapidly explore and optimize design spaces for climate resilience, rather than relying on time-consuming and limited physics-based simulations.
