Yeşil çatı ve duvar sistemleri, enerji verimliliğinin artırılması, karbon emisyonlarının azaltılması ve kentsel ısı adası etkisinin hafifletilmesi gibi çevresel faydalar sunan sürdürülebilir mimari uygulamalardır. İç ve dış ortam sıcaklık farklarını azaltmak için bina cephelerine entegre edilen bu sistemler, ısıtma ve soğutma gereksinimlerini optimize ederken estetik, akustik ve hava kalitesi açısından da avantajlar sağlamaktadır. Bu çalışma, Karadeniz Teknik Üniversitesi Hasan Polat Kapalı Spor Salonu'nun güney cephesine entegre edilen yeşil duvar sisteminin enerji performansı üzerindeki etkisini araştırmaktadır. Simülasyon analizleri, yeşil duvarın mevcut cepheye kıyasla yıllık ısıtma yükünü %1,1 ve operasyonel karbon emisyonlarını %0,67 oranında azalttığını göstermektedir. Bununla birlikte, somutlaştırılmış karbon miktarında %2,06 ve maliyette %1,4'lük bir artış gözlemlenmiştir. Doğu Karadeniz bölgesinin nemli ve ılıman iklim koşulları, bitki örtüsünü yıl boyunca canlı tutarak yeşil duvar sistemlerinin etkinliğini artırabilir. Ayrıca, yüksek nem seviyelerinin neden olduğu yoğuşmayı dengeleyerek yapı malzemelerinin korunmasına da katkıda bulunabilir. Sonuç olarak, yeşil duvar sistemleri bu tür iklim bölgelerinde enerji tasarrufu ve sürdürülebilirlik için önemli bir strateji olarak düşünülebilir.

The Effects of Green Wall Applications on Heating Load and Carbon Emissions: Karadeniz Technical University

Öz

Green roof and wall systems are sustainable architectural practices that offer environmental benefits such as increasing energy efficiency, reducing carbon emissions, and mitigating the urban heat island effect. These systems, which are integrated into building façades to reduce indoor and outdoor temperature differences, optimise heating and cooling requirements while also providing advantages in terms of aesthetics, acoustics, and air quality. This study investigates the effect of the green wall system integrated into the south façade of Karadeniz Technical University Hasan Polat Indoor Sports Hall on energy performance. The simulation analyses show that the green wall reduces the annual heating load by 6.84% and operational carbon emissions by 4.54% compared to the existing façade. However, an increase of 13.1% in the amount of embodied carbon was observed. The humid and mild climatic conditions of the Eastern Black Sea region can increase the effectiveness of green wall systems, keeping vegetation alive throughout the year. It can also contribute to the preservation of building materials by stabilising condensation caused by high humidity levels. As a result, green wall systems can be considered as an important strategy for energy saving and sustainability in such climate zones.
