“…Παράλληλα έχουν την ικανότητα να συγκρατούν μικρά σωματίδια σκόνης και να μειώνουν το θόρυβο (Korjenic et al, 2016). Γενικότερα τα φυτά σε μια πόλη πέρα από την αισθητική αναβάθμιση που προσφέρουν μπορούν να βελτιώσουν και την ποιότητα ζωής των κατοίκων των πόλεων κι έτσι να συμβάλουν στον ΣΒΑ 11 (βιώσιμες πόλεις και κοινωνίες) (Yilmaz et al, 2017).…”

Από το 1987 που ορίστηκε πρώτη φορά η έννοια της Βιώσιμης Ανάπτυξης έως σήμερα, έχει διατηρηθεί στο διεθνές προσκήνιο και έχει ευρεία αποδοχή. Τις τελευταίες δεκαετίες ενσωματώνεται και στην εκπαίδευση ως μέσο επίτευξης ενός βιώσιμου μέλλοντος. Σκοπός της παρούσας εργασίας είναι να διερευνηθούν οι απόψεις μαθητών 16-17 ετών σχετικά με την Βιώσιμη Ανάπτυξη και τη συμβολή των φυτών σε αυτήν. Για τη συλλογή ποιοτικών και ποσοτικών δεδομένων χρησιμοποιήθηκε ερωτηματολόγιο. Τα αποτελέσματα δείχνουν ότι η πλειοψηφία των μαθητών αδυνατεί να ορίσει τη Βιώσιμη Ανάπτυξη. Ως προς τα φυτά θεωρούν ότι συμβάλλουν θετικά στη Βιώσιμη Ανάπτυξη.

“…They found the thermal comfort of a layout of two rows of trees is better than that of a layout of street trees in the center; proper ventilation is important for the improvement of the thermal comfort of roads; and vegetation is more effective in improving thermal comfort under calm vertical wind than strong skew wind [15]. Yilmaz et al (2018) found that vegetation, public space layouts, street orientation, and the height and shape of the buildings can have a significant impact on the thermal comfort of street canyons. These factors need to be well considered when improving the thermal comfort of street canyons [16].…”

“…Cao et al (2022) pointed out that street trees on pedestrian streets have an improvement effect on the thermal comfort of street canyons in summer and a deterioration effect on the thermal comfort of street canyons in winter [7]. Yilmaz et al (2018) believe that deciduous trees should be given priority for improving the thermal comfort of street canyons because they can effectively block sunlight and fully utilize transpiration effects in the summer. In winter, due to the shedding of their leaves, their canopy no longer blocks sunlight from shining onto the street canyons.…”

The urban heat island effect has become a widely concerning issue worldwide. Many researchers have made great efforts to improve the summer thermal comfort of urban street canyons by optimizing street greening. Relatively less research has focused on how to improve the thermal comfort of street canyons by optimizing street greening during cold days. Many researchers have proposed strategies to improve the summer thermal comfort of street canyons using road greening. This may have a significant negative impact on the winter thermal comfort of street canyons due to the lack of consideration of the impact on hot and cold days simultaneously, especially when the road green space is mainly composed of evergreen tree species. We aimed to explore the impacts of urban street greening on thermal comfort on hot and cold days at the same time. We used Zhutang West Road in Changsha, China, as an example and built six different models to explore the impacts of the street vegetation types, number of street trees, tree heights, crown widths, and Leaf Area Index on the thermal comfort of the street canyon. In addition, we also considered the impact of different building features and wind directions on the thermal comfort of the street canyon. We employed ENVI-met (version 5.5.1) to simulate different urban street greening models. The results show that the model with a high tree canopy density, tall trees, large and dense crowns, and sufficient building shade has good thermal comfort on hot days (the average physiological equivalent temperature (PET) is 31.1 °C for the study period) and bad thermal comfort on cold days (the PET is 13.3 °C) when it is compared with the other models (the average PETs are 36.2 °C, 31.5 °C, 41.5 °C, 36.2 °C, and 35.5 °C, respectively, on hot days and for other models). In addition, the model with a very large number of short hedges has a positive impact on thermal comfort during hot days (the PET is 31.1 °C). The PET value of another comparable model which does not have hedges is 31.5 °C. Even if the model with a small building area has good ventilation, the small building shade area in the model has a more obvious impact and the model has relatively good thermal comfort during cold days (the PET is 14.2 °C) when it is compared to models with bigger building areas (the PET is 13.9 °C). In summer, when the wind is parallel to the direction of the street canyon, the wind speed in the street canyon is high and the model has relatively good thermal comfort (the PET is 35.5 °C) compared with another model which has different wind direction and lower wind speed at the street canyon (the PET is 36.2 °C). In winter, when the wind is perpendicular to the direction of the street canyon, buildings and trees have a strong windproof effect and this is beneficial to the improvement of thermal comfort (the PET is 15.3 °C for this model and 13.9 °C for another comparable model). This research lays a solid foundation and encourages people to think about the impact of building and tree composition and configuration on the thermal comfort of street canyons during hot and cold days simultaneously.

“…Termal konforun belirlenmesinde basit ve karmaşık olarak isimlendirilen birçok iklim modeli kullanılmakta, zaman zaman geçmiş yıllara ait meteorolojik veriler ile geleceğe dönük senaryolarda üretilebilmektedir (De Ridder, 2015;Yılmaz et al, 2018a;Yılmaz et al, 2018b). Termal konforlu mekanları belirlemede kullanılan modellerin yanı sıra son yıllarda termal kamera kullanımı da bu alanda hız kazanmıştır.…”

ÖZ: Kentsel nüfusun hızla arttığı yaşam alanlarında, konut ihtiyacını karşılamak için yapılan çalışmalar sonucunda başta açık-yeşil alanların azalması olmak nedeniyle, hava kirliliği, çarpık kentleşme gibi çeşitli çevre sorunları ortaya çıkmakta ve bu durum kentlerin termal konforunu olumsuz yönde etkilemektedir. Atatürk Üniversitesi Yerleşkesi içinde yer alan farklı niteliklere sahip mekanlar ile çeşitli renklerdeki doğal otsu bitki örtüsü ve mevsimlik bitkilerin yüzey sıcaklıkları termal kamera ile kaydedilmiştir. 2018 yılı Temmuz ayında havanın açık olduğu zamanda, bakı, rakım ve mevki olarak birbirine yakın mekanlarda bulunan ortamlardan alınan kayıtlardan, 6 tanesi seçilerek, bu alanlardaki 12 farklı niteliğe sahip mekan saat 15:00' e göre analiz edilmiştir. Alınan ölçümler ve yapılan değerlendirmeler sonucunda; doğal otsu bitkilerin ortamın mevcut sıcaklık değerine göre daha serin bir ortam oluşturduğu, yapısal alanların ise en yüksek sıcaklık değerine sahip olduğu tespit edilmiştir. Benzer biçimde, çim derzli kaldırımın, andezit taş kaldırımdan ortalama olarak 12.0 0 C daha serin çıktığı belirlenmiştir. Yapılan analiz ve değerlendirmeler neticesinde, kentsel alan planlamalarında termal konforun sağlanması açısından doğal otsu bitkilerin kullanımının önemli olduğu, planlama açısından iklim faktörünün kullanımının gerekliliği vurgulanarak önerilerde bulunulmuştur.
