How Climate Affects the City, How the City Affects Climate: Designing Scales of Architectural Intervention for Resilient Living

This chapter explores the reciprocal relationship between climate change and urban form, framing architecture and design as critical tools for both understanding and transforming this interaction. As cities face intensifying climate stress—from urban heat islands to flooding and extreme temperature variability—they are simultaneously active contributors to the crisis through emissions, land sealing, and unsustainable energy and water cycles. In the context of climate change, applied design refers to the tangible implementation of spatial, material, and environmental strategies that respond directly to climatic challenges. Unlike abstract or speculative visions, applied design engages with real-world constraints—technological, social, and ecological—to produce a measurable impact on the urban environment and the quality of life of its inhabitants. However, despite its centrality, design often remains at the background of climate discourse, overshadowed by policy, data modelling or engineering-led approaches. Architecture is too frequently treated as a passive container of climate action rather than an active agent capable of shaping how cities behave, adapt, and regenerate. We argue that this is a fundamental oversight. Design decisions influence energy use, emissions, water cycles, thermal comfort, and even the emotional connection people develop with places. As such, architecture must be repositioned from the periphery to the forefront of climate transformation. Analysing applied design through realised case studies, this chapter proposes a flexible but rigorous design framework suggesting ways to transform the urban–climate relationship. In particular, three main contemporary urban challenges, intertwined to climate change and requiring integrated design approaches, are going to be analysed: (1) the loss of control over urban water, exacerbated by impermeability and irregular rainfall; (2) rising temperatures and heat waves, amplified by urban heat islands; and (3) greenhouse gas emissions from transport, construction and inefficient land use. The chapter therefore proposes a climate resilience framework that breaks down climate-resilient design into three categories of interventions: (1) Stopping the problem—through reducing emissions, using renewable materials and passive systems, and increasing urban permeability. (2) Address the consequences—through adaptations to extreme events (such as floods and heat waves), flexible typologies and decentralised water infrastructure. (3) Reverse and co-evolve—by designing with natural processes, promoting biodiversity, ecological regeneration and sustainable resource management. Our methodology adopts a multi-scalar lens that includes the building, neighbourhood (or precinct), and urban ecological territories, and integrates spatial strategies, material technologies, and governance tools. At each scale, we identify specific architectural elements that can shift the city from reactive to proactive: from thermally insulated façades and black–grey–white water cycles at the building scale, to public shading systems and permeable paving at the neighbourhood level, to green corridors and watershed-based planning at the city scale. Ultimately, if climate design is to move from aspiration to transformation, it must engage also with the social, cultural, and economic structures that shape the urban condition, addressing potential limitations of uptake. This chapter therefore argues for a flexible yet rigorous design framework—grounded in evidence, tested through application, and guided by equity—that recognises both the power and the limitations of architecture in the face of the climate crisis. Through this approach, the chapter contributes to the first section of the volume, Principles and Innovative Design Approaches for Climate-Resilience, offering innovative design principles that merge environmental necessity with spatial justice and human wellbeing.
