Kentsel dış mekânların başarılı bir şekilde kullanılması termal konfor seviyelerinin yüksekliğiyle ilgilidir. Özellikle soğuk iklimlerde açık kamusal alanların tasarımı, kentlilerin bu alanlarda daha fazla vakit geçirebilmeleri için önemlidir. Kış güneşini alan, soğuk rüzgârlardan korunaklı ve mekân kurgusu ile ilgi uyandıran alanlarda dış mekân kullanım süresi artmaktadır. Bu doğrultuda çalışmanın amacı, Erzurum’un en işlek caddesi üzerinde bulunan 4 farklı kamusal alanın soğuk iklim koşullarıyla uyumluluğunun mikro-iklim simülasyonları yoluyla test edilmesidir. Bu süreçte alanların güneşe erişim, rüzgâr kontrolü, kar yönetimi ve bitki örtüsü dağılımındaki mevcut durumları incelenmiştir. Haritalarının üretilmesi ve değerlendirilmesi sürecinde ENVI-met yazılımı kullanılmıştır. Simülasyon sonuçları ve yazından elde edilen teorik bilgilerin bütüncül olarak kullanımıyla, dış mekân konforunun kış aylarında 0.5°C ile 1oC’ye kadar arttırılabileceği tespit edilmiştir. Sonuçlar paydaşlara dış mekân çalışma alanlarında termal konforu iyileştirmek ve sürdürülebilir şehirler geliştirmek için daha iyi yönergeler sağlanabileceğini göstermiştir.

Recommendations for the Improvement of Outdoor Comfort Conditions in Cold Climate: Erzurum

Öz

The intensive use of urban outdoor spaces in cities is related to high levels of thermal comfort. Especially in cold climates, the design of public spaces is important for the residents of the cities to spend more time in these areas. The duration of outdoor use increases in areas that receive the winter sun, are sheltered from cold winds and are attractive with their spatial organization. In this direction, the aim of this study is to test the compatibility of 4 different public spaces on the busiest street of Erzurum with cold climate conditions through micro-climate simulations. In this process, the current conditions of the areas were analyzed in terms of solar access, wind control, snow management and vegetation distribution. ENVI-met software was used to produce and evaluate the maps. With the integrated use of simulation results and theoretical knowledge, it was determined that outdoor comfort can be increased by 0.5°C to 1oC in winter. The results provide guidelines to stakeholders to improve thermal comfort in outdoor workspaces and develop sustainable cities.
