Designing Urban Semi-Open Spaces with Energy-Modulation Capabilities to Enhance Climate Resilience

Urban environments are increasingly exposed to climate-related stresses—including extreme heat, intensified solar radiation, and fluctuating wind and humidity patterns—highlighting a growing need for spatial strategies that strengthen environmental resilience. Semi-open spaces, positioned between fully indoor and outdoor environments, represent an underutilized design layer capable of modulating microclimates while supporting social, ecological, and energy-performance goals. This study investigates how semi-open urban spaces can be designed with active and passive energy-modulation capabilities to reduce vulnerability to climate extremes and enhance overall urban resilience. Employing a multidisciplinary approach, the research integrates urban climatology, bioclimatic architecture, computational simulation, and environmental psychology. A mixed-method framework is applied consisting of (۱) a systematic review of energy-responsive urban design strategies; (۲) microclimate modelling of semi-open space typologies under various climate scenarios; (۳) evaluation of adaptive features such as phase-change materials, radiative-cooling surfaces, dynamic shading, evaporative and vegetative systems; and (۴) a user-comfort analysis examining thermal perception and behavioral patterns. The simulations assess impacts on heat mitigation, energy exchange, daylight performance, wind flow regulation, and human thermal comfort across three representative climate zones. Results indicate that well-designed semi-open spaces can reduce mean radiant temperature by ۱۰-۱۸°C during peak heat events, lower energy demand for adjacent buildings by ۱۲-۲۵%, and improve perceived thermal comfort by ۲۵-۴۰% depending on the adaptation strategy applied. The study identifies key design variables including orientation, material emissivity, airflow porosity, and adaptive-envelope technologies that most strongly influence microclimatic modulation. Furthermore, the findings emphasize the co-benefits of energy-modulating semi-open spaces, such as enhanced social cohesion, increased urban biodiversity, and improved walkability during extreme weather. The paper concludes with a proposed resilience-oriented design framework to guide planners, architects, and policymakers in integrating energy-modulating semi-open spaces into future urban development. By bridging spatial design with climate-responsive technologies, the research demonstrates that these hybrid environments can serve as a critical buffer in climate-adaptive cities, offering both environmental protection and enhanced quality of life.
