“…[13] investigated the relationships between urban morphology and precinct ventilation performance in coastal Sydney, Australia, and their influence on the UHI and the outdoor thermal comfort on the basis of PET index. In the study conducted by Darbani et al [14], researchers sought to discover the impact of urban forms' multi-characteristics such as H/W ratio, street orientation, tree canopy cover, and building materials on the pedestrian outdoor thermal comfort arid climate of the city of Mashhad in Iran. This last study is based on simulation with ENVI-met software, and Arcmap to calculate the (UHI) in Mashhad city.…”

Oases settlements are common entities of human agglomerations throughout desert regions. Oases settlements face several environmental challenges such as climate change, which can render them insufferably hot and unlivable within decades. Therefore, this study aims to assess the outdoor thermal comfort variation within three different oases urban fabrics of Tolga Oases Complex in Algeria. The overarching aim is to quantify thermal comfort and guide landscape, and urban designers improve outdoor thermal comfort. The methodology relies on microclimatic measurements and weather datasets (TMY2, TMY3, TMYx), combining observations and numerical simulations. A total of 648 Physiological Equivalent Temperature (PET) values were calculated in three different urban fabrics in Tolga Oases Complex, Algeria. Between 2003 and 2017, a remarkable microclimatic change was found, causing a high and accelerated heat stress level of 76%. The study results inform architects, urban planners and climatologists about climate change effects and urban sprawl impact on the oases lands. Moreover, urban strategies should seek mitigation and adaptation benefiting from the existing green infrastructure of palm groves.

“…Salman et al [38] constructed 18 scenarios from three UHI mitigation strategies (vegetation, cool materials, and urban morphology) and used the numerical simulation software ENVI-met to evaluate the effects of different scenarios on outdoor human comfort in Baghdad, Iraq. Sanagar et al [39] performed microclimate simulations and analyses in ENVI-met software and calculated UHII using ArcMap. They ultimately demonstrated that zoning for UHII can be used as an alternative to zoning for urban form based on OTC, especially in large cities where urban form data collection may be difficult due to limited time and resources [40,41].…”

The worsening urban heat island (UHI) effect poses a great challenge to the thermal comfort of people outdoors. However, there has not been a summary of the mechanisms by which UHI affects outdoor thermal comfort (OTC). This paper reviews the commonly used OTC evaluation indexes, data collection methods, and mitigation measures and discusses the relationship between UHI and OTC. The review is limited to peer-reviewed journal publications found in five databases: Science Direct, Scopus, Google Scholar, PubMed, and Web of Science. The review results indicate that physiological equivalent temperature (PET), universal thermal climate index (UTCI), and wet bulb globe temperature (WBGT) are the most widely used indexes in outdoor thermal comfort studies. The data collection methods mainly include questionnaire surveys, measurement, simulation, and formula calculation. There are four main approaches to mitigating the UHI effect in order to improve the comfort of people outdoors: vegetation strategies, water strategies, urban planning strategies, and material strategies. Future research can focus on developing OTC research methods and indexes and combine thermal comfort with visual comfort, auditory comfort, etc. to better evaluate the overall comfort.

“…Birçok çalışma, kentsel alanlarda insanların dış mekanlarda önemli oranda zaman geçirmesi nedeniyle, insanların sağlık ve memnuniyetini artırmak için en önemli konulardan biri olarak termal konforun sağlanmasına odaklanmaktadır (Erell ve ark., 2012;Hong ve ark., 2019;Sanagar Darbani, 2021). En konforlu termal konfor koşullarını bulmak amacıyla basit ve karmaşık indeksler geliştirilmiştir (Maniatis ve ark., 2020).…”

Kentlerdeki dış mekân termal konfor, kentsel ortamlarda artan sıcaklıklar ile daha çok önem kazanmaya başlamıştır. Çalışmada Antalya ili Konyaaltı ilçesinin dış mekân termal konfor koşullarının zamansal ve mekansal dağılımının belirlenmesi amaçlanmıştır. Bu amaç doğrultusunda ilk olarak Konyaaltı ilçesi ve yakın çevresindeki meteoroloji gözlem istasyonlarından iklim verileri (sıcaklık, nem, rüzgâr hızı ve bulutluluk) elde edildi. Çalışmada dış mekân termal konfor koşulları, iklim parametrelerinin yanı sıra insan enerji dengesini de hesaplamalarına dâhil eden ve en yaygın kullanılan termal konfor indekslerinden biri olan FES (Fizyolojik Eşdeğer Sıcaklık) ve RayMan modeli kullanılarak hesaplandı. RayMan Model'i kullanılarak üretilen aylık FES değerlerinin mekânsal dağılımı CBS ortamında IDW analizi kullanılarak elde edildi. Sonuç olarak, Konyaaltı kent merkezi ve yakın çevresinde termal konfor koşulları ilkbahar ve sonbahar mevsiminde kısmen oluşmakta ve diğer mevsimlerde sıcak ve soğuk stres nedeniyle termal konfor koşulları oluşmamaktadır.
