Mekansal Termal Konfor Açısından Atatürk Üniversitesi Yerleşkesi Termal Kamera Görüntülerinin Analizi

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 ⁰C 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.

Atatürk University Campus in terms of Spatial Thermal Comfort Analysis of Thermal Camera Images

Abstract

Various environmental problems such as decreased outdoors/green spaces, air pollution, distorted urbanization emerge and cause lower thermal comfort in the cities as a result of the activities carried out to meet the need for housing in the residential areas where the urban population is rapidly increasing. Thermal cameras are used to record the surface temperature of spaces with different characteristics in Atatürk University Campus; the natural herbaceous plants in various colors and seasonal plants. 6 of records made in July 2018 in clear weather with similar characteristics in terms of their position to the sun, altitude, and location are selected and 12 locations with disparate characteristics in those records are analyzed according to 15:00 o'clock. As a result of the measurements and evaluations, it was noted that natural herbaceous plants form a cooler environment compared to the current temperature of the environment and asphalt has the highest temperature value in conditions. Also, it was determined that the grass joint pavement is on average 12.0 ⁰C cooler than the stone pavement with andesite material.  As a result of the analyses and evaluations, some suggestions were developed by emphasizing the importance of natural herbaceous plants in the provision of thermal comfort in urban area planning and the necessity of the use of climate factor in terms of planning.
