Abstract

Dünya genelinde birçok binada, eski ve verimsiz sıhhi tesisat sistemleri bulunmaktadır; yoğun nüfuslu üniversite kampüslerinde bu durum, su tüketiminin çok yüksek olmasına yol açarak sürdürülebilir su yönetimi açısından ciddi bir sorun oluşturmaktadır. Bu çalışma, İstanbul’daki bir üniversite binasında mevcut sıhhi sistemlerin su tüketimi üzerindeki etkisini analiz ederek, LEED yeşil bina sertifikasyonu kriterlerine uygun modern ve verimli sistemlerin uygulanmasıyla elde edilebilecek su tasarrufunu değerlendirmeyi; ayrıca Türkiye'deki üniversite kampüslerinde su kullanım verimliliğinin artırılmasının çevresel, sosyal ve ekonomik önemini vurgulamayı amaçlamaktadır. Öncelikle mevcut sistemlerin yıllık su tüketimi TS1258 standardı dikkate alınarak hesaplanmış, ardından yüksek verimli su armatürleri kullanılarak yeni bir su tüketim modeli oluşturulmuştur. Bulgular, önerilen sistemlerin binanın su verimliliğini yaklaşık %78 oranında artırabileceğini ve yatırım maliyetinin yaklaşık 14 ay içinde geri kazanılabileceğini göstermektedir. Çevresel sürdürülebilirlik açısından, çalışma su kaynaklarının korunmasına katkı sağlarken, sosyal açıdan suya erişimde eşitliğin sağlanması ve ekonomik açıdan üniversiteler için uzun vadede önemli maliyet tasarrufu sunmaktadır. Ayrıca, TS1258 standardının cinsiyet temelli su tüketim farklılıklarını göz önünde bulundurmadığı belirlenmiştir. Bu kapsamda, üniversitelerde daha verimli su yönetimi stratejilerinin benimsenmesi için politika yapıcılara rehberlik edecek önemli veriler sunulmaktadır.

WATER EFFICIENCY POTENTIAL OF UNIVERSITY CAMPUSES TOWARDS LEED CRITERIA: A CASE STUDY IN TURKEY

Abstract

Many buildings worldwide feature outdated and inefficient sanitary systems, which is particularly pronounced in densely populated university campuses, where high water consumption poses a significant challenge to sustainable water management. This study aimed to investigate the impact of installed sanitary systems on water consumption in a university building in Istanbul and assess potential savings through high-efficiency systems as per the LEED certification criteria, and emphasize the environmental, social, and economic significance of improving water use efficiency on university campuses in Turkey. Annual consumption was first calculated using the TS1258 standard, then a new model with efficient fixtures was developed. Results showed that the proposed systems could increase water efficiency by approximately 78% with a payback period of 14 months. From an environmental perspective, the study highlights the importance of water conservation, and from a social standpoint, it promotes equity in water access, and economically, it demonstrates significant cost reductions and long-term financial savings. Furthermore, the research identifies a gap in the TS1258 standard, which did not consider gender-based differences in water use. By presenting key data for policymakers and administrators, this study aims to emphasize the necessity of adopting more efficient water management strategies in educational institutions and contribute to future research on sustainable campus development.
