Abstract

Outdoor thermal comfort (OTC) studies have gained global attention in the last two decades, with noteworthy results of increasing heat stress. Heat Issues in urban areas disturb the thermal balance and create a dilapidated urban living environment. The thermal environment is quite influencing in promoting open public spaces. India, a tropical country, deals with intense heat issues periodically throughout the year. There has been an increasing trend of OTC studies in India in the last decade. It is necessary to chronicle the state of knowledge and the current circumstances in the country.
The study aims to investigate, analyze, and summarize the ongoing scenario of OTC studies in the Indian context. This systematic literature review (SLR) is a comprehensive analysis of 38 studies obtained and reviewed through five stages. It investigates the available database to understand the thermal environment, thermal parameters, perception, preference, and overall thermal comfort in open spaces between different built forms. The outcome expansively summarises the various parameters, approaches, and scenarios to assess OTC. The findings of the study encourage the annual assessment of OTC conditions with consideration of several aspects of different climatic zones. Standardization in the process of OTC assessment and the development of OTC models in the Indian Scenario is found to be of utmost importance. Thermal neutrality values were found to vary between 19 °C - 32 °C over several locations. The in-depth discussion has addressed the precise gaps and future scope, specifically in the Indian context.
开放式公共空间的热舒适度--印度背景下的重要评论
室外热舒适度(OTC)研究在过去二十年里得到了全球的关注,值得注意的是,热压力越来越大。城市地区的热问题扰乱了热平衡,造成了破旧的城市生活环境。热环境对促进开放式公共空间具有相当大的影响。印度是一个热带国家,全年不时出现酷热问题。近十年来,印度的开放式公共空间研究呈上升趋势。本研究旨在调查、分析和总结印度当前的户外活动研究情况。本系统性文献综述(SLR)对通过五个阶段获得和审查的 38 项研究进行了全面分析。它调查了现有的数据库,以了解不同建筑形式之间开放空间的热环境、热参数、感知、偏好和整体热舒适度。研究结果全面总结了评估开放空间热舒适度的各种参数、方法和方案。研究结果鼓励每年对开放空间的热舒适度进行评估,并考虑到不同气候区的多个方面。研究发现,在印度情况下,OTC 评估过程的标准化和 OTC 模型的开发至关重要。多个地点的热中性值在 19 °C - 32 °C 之间变化。深入的讨论探讨了印度的具体差距和未来范围。
