Şehir hastanelerinde enerji maliyetlerinin yönetimi: Öncelikli stratejilerin belirlenmesi

Öz

Şehir hastaneleri, yapıları gereği oldukça büyük yapılardır. Buna bağlı olarak, enerji tüketim miktarları da oldukça yüksektir. Bu hususlar, sağlık hizmetlerinin sürdürülebilirliği ve kalitesi ile doğrudan ilişkilidir. Dolayısıyla, şehir hastanelerindeki enerji tüketiminin ve maliyetlerinin yönetilmesi önemlidir. Ancak, şehir hastanelerindeki enerji tüketimini etkileyen birçok faktör bulunmaktadır. Bu faktörlerin tamamına aynı anda müdahale etmek karar verici pozisyonundakiler açısından oldukça güçtür. Bu nedenle, şehir hastanelerinde enerji maliyetlerine etki eden faktörlerin önem derecesine göre ağırlıklandırılması gerekir. Bu doğrultuda, çalışmanın amacı şehir hastanelerinde enerji maliyetlerini azaltabilmek amacıyla öncelikli stratejilerin belirlenmesidir. Literatür tabanlı olarak belirlenen 8 kriter analiz edilmiştir. Analiz p,q-SFS-AHP yöntemi ile gerçekleştirilmiştir. Belirsizliğin minimize edilebilmesi için bulanık sayılardan faydalanılmıştır. Bu sayede, daha doğru sonuçlar elde edilir. Analiz sonuçları, “Binaya yalıtım yapılarak fazla enerji tüketiminin önüne geçilmesi” kriterinin şehir hastaneleri için en önemli faktör olduğunu göstermektedir (w=0,256). Süreci etkileyen diğer önemli kriter ise “Yenilenebilir enerji alternatifleri ile enerji bağımlılığının azaltılması”dır (w=0,234). Dolayısıyla, binalara yalıtım yapılması önemli bir gerekliliktir. Ayrıca, şehir hastanelerinin kendi enerjisini üretebilir konuma gelmesi sürdürülebilirlik açısından önemlidir.

Management of energy costs in city hospitals: Identifying priority strategies

Öz

City hospitals are quite large structures due to their nature. Accordingly, their energy consumption amounts are also quite high. These issues are directly related to the sustainability and quality of healthcare services. Therefore, it is important to manage energy consumption and costs in city hospitals. However, there are many factors affecting energy consumption in city hospitals. It is very difficult for decision makers to intervene in all of these factors at the same time. Therefore, the factors affecting energy costs in city hospitals should be weighted according to their importance. Accordingly, the aim of this study is to identify prioritized strategies to reduce energy costs in city hospitals. Based on the literature, 8 criteria were analyzed. The analysis was carried out with the p,q-SFS-AHP method. Fuzzy numbers are used to minimize uncertainty. In this way, more accurate results are obtained. The results of the analysis show that the criterion “Preventing excess energy consumption by insulating the building” is the most important factor for city hospitals (w=0.256). The other important criterion affecting the process is “Reducing energy dependency with renewable energy alternatives” (w=0,234). Therefore, insulation of buildings is an important requirement. In addition, it is important for city hospitals to be able to produce their own energy in terms of sustainability.
