“…However, considering the acupuncture projects primarily operate on a small scale with community engagement, two other tools become more significant within our framework. Frontiers in Environmental Science frontiersin.org materials, and the configuring walkways, as well as choosing building and surface material, are related to transportation interventions within citizen participation (Ruefenacht and Acero, 2017). Furthermore, urban geometry offers numerous opportunities to mitigate neighborhood and small-scale urban temperatures, particularly considering shade and wind flow as crucial factors (Gago et al, 2013).…”

Rising temperatures, a major global environmental challenge, negatively impact health, the environment, society, and the economy. Surface Urban Heat Islands (SUHI), exacerbated by urbanization and climate change, intensify vulnerabilities for urban areas and residents. Urban planning and design aime to reduce these vulnerabilities through large-scale and small-scale interventions. However, addressing the significance of the capillary effects resulting from small-scale interventions and bottom-up community engagement is important. Urban acupuncture (UA) is an emerging approach in contemporary urban planning and design that focuses on small-scale interventions to mitigate the effects of SUHIs at the community level. This study develops a framework for mitigating the impacts of SUHIs through UA implementation in urban design. The proposed framework consists of two key phases: diagnosis and prescription. During the diagnosis phase, we analyzed heat-vulnerable points to identify indicators contributing to the development and exacerbation of the SUHIs. Then, we employed the Matrix of Cross Impact Multiplications Applied to a Classification (MICMAC) technique to comprehensively assess 75 influential indicators related to urban structure across various aspects and scales, focusing on the mesoscale. Among them, 30 leading indicators were identified, of which environmental and morphological indicators emerged as significant catalysts. Moving on to the prescription phase, we developed a UA-based framework called the “5 Wh Question” which addresses five fundamental questions: why, who, what, how, and where. Our findings can provide comprehensive solutions for policymakers and urban planners to address the identified heat-vulnerable points.

“…The anthropogenic factors that contribute to the UHI effect can also be regulated with increased use of renewable energy sources. Improving transportation systems by promoting public transport, integrating route systems, promoting active mobility, and reducing the number of vehicles can also enhance fuel combustion efficiency and reduce the residual energy that is converted into heat [28].…”

The increasing trend of urbanisation has resulted in land use changes and increased urban activities, which led to the emergence of the Urban Heat Island (UHI) phenomenon. The readiness of urban design and planning in mitigating UHI becomes crucial, to reduce the demand for cooling energy and enhance productivity. This study aimed to calculate the cooling capacity index of the Karet Tengsin Platinum Area design, using InVEST 3.12.1, based on shading, evapotranspiration, albedo, and distance from cooling islands, and it has a range of 0-1. The index was further analysed, using the kernel density method, to examine the spatial density patterns to identify the priority features that need to be intervened to mitigate UHI in the Area. The research findings show that, the Karet Tengsin Platinum Area design has a cooling capacity index ranging from 0.22 to 0.83, dominated with a low index value, below 0.3, indicating that, this area has poor cooling capacity. Low index values are distributed in built-up areas, which show that, the materials used in built-up areas need to be prioritised as features that need to be intervened to enhance the cooling capacity. Additionally, this study also discusses urban cooling strategies, through other features that are less explored in the modelling. This study method can be used as a reference for urban designers in integrating urban cooling approaches, as UHI mitigation strategies, in urban area planning and design.

“…Previous studies have proposed many heat mitigation measures to reduce radiation and air temperature in spaces and increase wind speed, including adding arti cial shading, tree-planting and misting systems, installing ventilation corridors and changing surface materials. The effectiveness of these measures has been well demonstrated in eld trials and simulation studies (He et al, 2020c;Nevat et al, 2021;Ruefenacht & Acero, 2017). However, considering the exact use of the space, these measures are not applicable to all types of outdoor spaces.…”

This study develops a quantitative method to assess the thermal usability (e.g. rideability, walkability, entertainmentability, exercisability, and workability) of outdoor spaces. The benchmark for thermal usability was assessed by four widely-used indicators (Wet Bulb Temperature (WBGT), Predicted Mean Vote (PMV), Physiologically Equivalent Temperature (PET) and Universal Thermal Climate Index (UTCI)).Among these ve dimensions of thermal usability, exercisability was the most signi cantly thermallyaffected, as WBGT was greater than 30℃, exercisability dropped to below 50%, while the other four usability dropped to below 75%. An empirical study based on eld experiments in Changzhou, China was performed. The results indicated that the quantitative method was capable of assessing the thermal usability of various urban spaces (e.g. basketball court, badminton eld, walkway space and natural lawn), and could guide people in spatial modi cations, outdoor activities and site management. The empirical studies also showed that air ow and radiation were the two critical meteorological factors, associated with urban infrastructure affecting the thermal usability of outdoor spaces. Activity metabolism showed a positive correlation with participant heat stress and a negative correlation with the thermal usability. Guidelines are used to guide participants to avoid optional activities and to provide them protective recommendations for necessary activities during periods of low thermal usability. Overall, this paper promotes methodological understandings of thermal usability, and provide policy makers, urban planners and designers, and urban managers with implications on effective heat solutions.
