In the upcoming period, city squares’ urban redesign will be crucial in achieving sustainable development goals. This study presents a systematic review of OTC-related studies for design squares using PRISMA 2020 methodology. A included total 173 papers from 2001 to 2023. The results identified five types—clusters based on four pre-defined criteria: approach, data collection methods, time duration, and primary objectives. clusters indicate that more than half all are related comparison thermal comfort heat mitigation measures. Most case were located one three climate zones: temperate oceanic (Cfb) (58 studies), hot summer Mediterranean (Csa) (40 or humid subtropical (Cfa) (28 studies). most common geometry analyzed square is medium-sized, rectangular, has dominant axel orientation south–north. Also, clusters, several research gaps identified, appropriate future research: majority traditionally considered areas, no typology configuration OTC assessment, lack local model assessing improving squares.

Lightweight shading devices like sails, canopies, and street-scale shelters are a key strategy for urban cooling. Studies indicate that interactions between characteristics such as height, thermal emissivity color, significantly affect outdoor comfort, those effects vary considerably with local context time. However, practical understanding of often focuses solely on blocking direct solar radiation. Integrating microclimate simulation into design workflows can optimize shade by considering all effects. This paper validates two using Ladybug Tools (LBT) modelling freestanding shade, proposing their applicability. A novel workflow models shortwave longwave lightweight materials differing from LBT's standard approach in radiation exchanges. Simulated mean radiant temperature (MRT) is validated against field measurements compared across both workflows. Field separate long contributions accurate MRT comparison, revealing tendency to overestimate The custom applied case study Turin, Italy, evaluating various MRT. Results demonstrate how material, ground time day interact influence cooling effects, emphasizing implications optimizing design.

As climate change intensifies, urban populations face growing threats from frequent and severe heatwaves, underscoring the urgent need for advanced risk assessment frameworks to inform adaptation strategies. This systematic review synthesizes methodological innovations in heatwave (2007–2024), analyzing 259 studies through bibliometric analysis (CiteSpace 6.4.R1) multi-criteria evaluation. We propose hazard–exposure–vulnerability–adaptability (HEVA) framework, an extension of Crichton’s triangle that integrates dynamic adaptability metrics supports high-resolution spatial assessment. Our reveals three key gaps: (1) Inconsistent indicator selection across studies; (2) limited microclimatic variations; (3) sparse integration IoT- or satellite-based monitoring. The study offers practical solutions enhancing accuracy, including refined weighting methodologies techniques. conclude by proposing a research agenda prioritizes interdisciplinary approaches—bridging planning, science, public health—while advocating policy tools address inequities heat exposure. These insights advance development more precise, actionable systems support climate-resilient development.
