“…Liner regression analysis is done between mean thermal sensation votes and thermal indices to determine the neutral PET range of that thermal indices. Two studies have used Ordinal logistic regression (Ali and Patnaik, 2018;Banerjee, Middel and Chattopadhyay, 2022) and one study (Manavvi and Rajasekar, 2023) used structural modelling equation (SEM). It is observed in that neutral PET range in urban park (Kumar and Sharma, 2022a) is wider than urban open areas (Kumar and Sharma, 2022b) in Haryana even in the similar climate zone.…”

Climate change has a negative impact on outdoor livability. Particularly in metropolitan settings, a rise in temperature has an impact on human health and thermal comfort. As a result of urbanization, the temperature in Indian cities is rising at an alarming rate.This paper intends to examine previous investigations into outdoor thermal comfort in Indian context. 35 papers are evaluated to provide a summary of the prior research and to look at the necessity and potential of outdoor thermal comfort studies in Indian cities. This review also emphasizes the procedures, data collection techniques, and software used.The paper examines research gaps, suggestions, and the potential scope of future research while highlighting the necessity of studies on outdoor thermal comfort. Future research is especially needed to encompass a variety of geographic regions, climatic zones, and other outdoor areas that have not been taken into account in previous studies. Furthermore, tourism purpose studies are lacking in the Indian context. For a better knowledge of the perceived thermal environment, it is also advised to combine quantitative and qualitative investigation.The results of this study can be used by urban planners and designers to improve the outdoor thermal environment. This study can also help researchers determine the scope of additional research on outdoor thermal comfort in the context of India.

“…Tneutral range was 22.10 °C to 27.56 °C. Similarly, Banerjee et al (2022) examine the issue in Mumbai, the financial capital of India, have discovered varied results in calculating the neutral PET for summer (28.0° C for Kumbhadwada and 35.5°C for Fashion Street) and for winter (23.2°C for Flower market 23.2°C for Fashion Street), although Mumbai has no such clear distinction between summer and winter, because of maritime climate.…”

A Parametric Analysis of Thermal Comfort of Street Vendors in the Traditional Settlements of Patna, India

High population and fewer opportunities in rural areas, coupled with migration has resulted in an increase of population in urban areas of developing countries like India. Unskilled labour and a low level of education have forced people to resort to street vending for their livelihood. Moreover, street vending does not need high levels of skills and there is also no rental burden. In fact, it has a very low capital requirement. They now make up about 2% of the population of the metropolis, an enormous growth in recent years. Therefore, street vendors involved in selling goods and services to people on the streets play a crucial role in urban economies. However, they have to frequently deal with difficult working conditions, such as exposure to thermal discomfort and poor air quality.This paper examines how thermal comfort affects street vendors on different road geometries and settlements. It is assumed that the built environment along the street is an important parameter that governs thermal comfort of the hawkers and vendors. In order to achieve the intended outcome of thermal comfort, the research uses the empirical data collection of weather parameters and uses it in established software (Rayman). It is verified by means of a systematic questionnaire survey conducted among the intended target group (vendors). As research methodologies, PET (°C)/PMV were calculated by gathering all the data (Physiological & Weather) for two different street geometries at the same time. The readings were taken for statistically significant sample for a large period of time during summer. In doing so, it compares, Physiological Equivalent Temperature (PET)/ Predicted Mean Vote (PMV) for traditional and modern streets.The findings show that traditional streets are thermally more compatible for street vendors in a composite climate where hot days are more, for most part of the year.

“…Extreme wet bulb temperatures across the tropics are also expected to increase in near-perfect unison with regional mean warming ( Zhang et al., 2021 ). Yet, extreme heat may still be underestimated in topographically complex and/or data-scarce areas, such as urban informal settlements ( Scott et al., 2017 ; Baruti et al., 2019 ; Banerjee et al, 2021 ), where regional meteorological models may not capture the intricacies of temperature and humidity variation and extremes at a local scale and in situ environmental monitoring is lacking ( Coffel et al., 2018 ; Wang et al., 2019 ). Indoor temperatures are rarely examined in informal settlements (but see Mukhopadhyay et al., 2021 and Wilby et al., 2021 ) and it may be assumed that adaptations, such as the use of air-conditioning, will be practiced ( Biardeau et al., 2019 ), even though mitigation of this kind is expensive and often unavailable to informal settlement households ( Satterthwaite et al., 2020 ).…”
