Abstract

Cities are dynamic systems that need to plan for development with resilience, while facing an increasing set of multidimensional challenges and emerging operating trends (e.g. Smart Cities) (Schmitt, 2015). In the framework of new Urban Strategies (Digital Europe Program, 2021-2027; Green Deal, 2019), local authorities play a key role in making the right decisions for covering current and future needs. Public/outdoor urban spaces are vital parts of cities as they define citizens’ quality of life and the ability of cities to respond to urban challenges. In this context, this research aims to support the decision-making process for shaping, designing and managing public/outdoor urban spaces by using measurable and multicriteria indicators to evaluate alternative climate-sensitive design and regeneration plans of urban areas within risk and uncertainty. Emphasis is placed on both supply and demand for outdoor urban areas. Demand is studied by disaggregate analysis for identifying citizens’ needs through questionnaire survey. Supply side is placed at the center of the research by developing a multiple-criteria assessment methodology of urban planning methods. The main evaluation criteria involve the bioclimatic impact of the studied methods, the air pollution detected in microclimate as well as financial cost for their implementation and operation. In particular, questionnaires’ results revealed that citizens prefer open spaces as they provide a feeling of freedom and the chance to be closer to nature. Based on these, citizens visit open spaces with green areas, incoorporating nature based solutions, as well as places that support walkability and green mobility. In addition, simulation and cost assessment results regarding the studied methods showed the planning solutions involving medium size plants and greenery are low cost interventions, creating favorable microclimate conditions and leading to medium CO2 concentration. The benefit of the current research is in the innovative, interdisciplinary and holistic approach of a complex real-word problem combining different research areas, such as environmental science, bioclimatic urban planning and decision-making process. The multiple-criteria analysis of urban plans leads to a model of the decision-making process on open urban spaces to enhance citizens’ quality of life and to ensure urban resilience as well as cities’ operational and sustainable future.
