Potential Contribution of Green And Blue Technologies to Reduce Heat Stress In Outdoor Spaces, Case of Guelma City-Algeria

Year 2020, Volume: 6 Issue: 1, 23 - 32, 01.06.2020

Abstract

Green and blue technologies in addition to their aesthetic and structural dimension, it offer the
possibility of modifying the urban microclimate by relying on a process of natural regulation. This paper
investigates the effect of microclimatic regulation of vegetation and water bodies in outdoor spaces during
heat stress, we measured air temperature, relative humidity and wind velocity during the hottest period of
2019. The study simulates four scenarios for the square of martyrs which is situated in Guelma city by using
Envi-met model. In scenarios 2 and 3 vegetation and water bodies were removed respectively, it has shown
high temperature and low humidity corresponding to heat stress sensation. The scenario of the current
outdoor space was ranked second in terms of microclimatic regulation while the scenario of recommended
water bodies and vegetation have shown the best microclimatic conditions in heat stress with low
temperature and high humidity and cool velocity. The findings show that the combined effect of vegetation
and water bodies could lead to an optimal microclimatic regulation, thus it could reduce heat stress in
outdoor spaces.

Yeşil ve Mavi Teknolojilerin Dış Mekânlarda Isı Stresini Azaltmaya Muhtemel Katkısı, Guelma Şehri - Cezayir Örneği

Year 2020, Volume: 6 Issue: 1, 23 - 32, 01.06.2020

Abstract

Yeşil ve mavi teknolojiler, estetik ve yapısal boyutlarına ek olarak, doğal bir düzenleme sürecine
dayanarak kentsel mikro iklimi değiştirme imkânı sunar. Bu makale, ısı stresi sırasında dış mekânlarda
bitki örtüsü ve su kütlelerinin mikro iklimsel düzenlemesinin etkisini araştırdı, 2019'un en sıcak döneminde
hava sıcaklığını, bağıl nemi ve rüzgâr hızını ölçtük. Kıskançlık modeli. 2. ve 3. senaryolarda vejetasyon ve
su kütleleri sırasıyla çıkarıldı, yüksek sıcaklık ve düşük neme karşılık gelen ısı stres hissi gösterdi. Mevcut
dış mekân senaryosu, mikroklimatik regülasyon açısından ikinci sırada yer alırken, önerilen su kütleleri ve
bitki örtüsü senaryosu, düşük sıcaklık ve yüksek nem ve serin hız ile ısı stresinde en iyi mikroiklim
koşullarını göstermiştir. Bulgular, bitki örtüsü ve su kütlelerinin birleşik etkisinin optimal bir mikro iklimsel
düzenlemeye yol açabileceğini, dolayısıyla dış mekânlarda ısı stresini azaltabileceğini göstermektedir.
