Yeşil kampüs, ekolojik şehrin önemli unsurlarından biridir. Yerleşim ve altyapı, enerji ve iklim değişikliği, atık, su, ulaşım ve eğitim yeşil bir kampüsün başlıca öğeleridir. Bu çalışma, yağmur suyu toplama sistemini içeren su tüketimi ve tasarrufuna odaklanmaktadır. Erciyes Üniversitesi, UI GreenMetric 2020-2021 sıralamasına göre Türkiye'de çevreye duyarlı üçüncü üniversite olmuştur. Erciyes Üniversitesi 2020 yılında toplam 7175 puanla dünyada 142. sırada yer alırken, 2021 yılında 7775 puanla 99. sıraya yükselmiştir. Bu makalede, Erciyes Üniversitesi için yağmur suyu hasadı yöntemi kullanılmıştır. Toplam hasat edilebilir su miktarı, çatı yüzey alanı × yıllık ortalama yağış miktarı × kayıp katsayısı hesabı esas alınarak hesaplanmıştır. Kayıp katsayısı, çatı formlarındaki farklılıklar göz önünde bulundurularak 0,75 olarak belirlenmiştir. Binaların taban alanları coğrafi bilgi sistemleri kullanılarak hesaplanmıştır. Erciyes Üniversitesi kampüs alanındaki çatılardan toplam hasat edilebilir su miktarı 64.635,432 m³ olarak hesaplanmıştır. Buna göre, Erciyes Üniversitesi'nde çatılardan yağmur suyu hasadı yapılarak yıllık su tüketiminin yaklaşık %7,55'inden tasarruf edilmesi, 1.066.477 TL tasarruf sağlanması ve yılda 7.181 kişiye su temin edilmesi mümkündür. Önerilen yağmur suyu hasadı yönteminin, Erciyes Üniversitesi'ni UI GreenMetric sıralamasında daha üst sıralara taşıyacağı, eko-kent yaklaşımına katkıda bulunacağı ve kampüs sürdürülebilirliğini geliştirmesine yardımcı olacağı sonucuna varılmıştır.

A green campus is one of the important aspects of an ecological city. Setting and infrastructure, energy and climate change, waste, water, transportation, and education are major elements of a green campus. This study focuses on water consumption and savings, which generally involves a rainwater harvesting system. Erciyes University became the third environmentally sensitive university in Turkey according to the UI GreenMetric 2020–2021 ranking. While Erciyes University was ranked 142nd in the world in 2020, with a total score of 7175, it rose to 99th place in 2021, with 7775 points. This paper investigates and describes a rainwater harvesting method for Erciyes University. The total harvestable water was calculated as the roof surface area × the average annual rainfall × the loss coefficient. The loss coefficient was set as 0.75 considering the differences in roof forms. The floor areas of the buildings were calculated based on data collected from geographic information systems. The total harvestable water was calculated to be 64,635.432 m³ from the roofs in the campus area of Erciyes University. Accordingly, it is possible to save approximately 7.55% of the annual water consumption, saving 1,066,477 TL and supplying water to 7,181 people per year by harvesting rainwater from the roofs at Erciyes University. It is concluded that the proposed rainwater harvesting method help Erciyes University rank higher in the UI GreenMetric ranking, contribute to the eco-city approach, and enhance campus sustainability.
