Calculating Payback Periods for Energy Efficiency Improvement Applications at a University Hospital

Artan enerji talebi ve mevcut fosil yakıt tabanlı kaynaklarının hızla tükenmesi, ülkelerin enerjiyi verimli kullanmasına, enerji tasarrufu yapmasına ve alternatif enerji kaynaklarını aramasına zorlamıştır. Enerji ihtiyaçlarını karşılamada başka ülkelere bağımlı olan bizim gibi gelişmekte olan ülkelerde, mevcut enerjiyi verimli kullanmak ve tasarruf çalışmaları yapmak daha büyük önem taşımaktadır. Hastaneler binalarda kullanılan toplam enerjinin yaklaşık olarak %6sını tüketmektedir. Isıtma, Havalandırma ve İklimlendirme sistemleri (IHİS), hastanede tüketilen elektrik enerjisinin büyük bir kısmını oluşturmaktadır. İklimlendirme sistemleri toplam tüketilen yaklaşık olarak %70inden sorumludur. Hastanedeki elektrik motorları ve aydınlatma sistemleri yaklaşık olarak toplam enerjinin %19-21lik kısmını harcamaktadırlar. Bu çalışmada, aydınlatma cihazları, elektrik motorları ve IHİS sistemleri üzerine yapılan detaylı çalışmalar sonucunda, bir üniversite hastanesinde bu cihazların enerji tasarruf potansiyelleri ve geri dönüşüm süreleri tahmin edilmiştir.

Bir Üniversite Hastanesinde Enerji Verimliliğini Artıran Uygulamaların Geri Dönüşüm Sürelerinin Hesaplanması

The increasing demand for energy and the depletion of existing fossil fuel based resources have forced the countries to realize the efficient use of energy, energy saving applications and searching alternative energy sources. Using the energy efficiently and performing energy saving studies have great importance for developing countries like ours that are dependent on other countries to meet their energy needs. Hospitals generally consume 6% of total energy in the buildings. Heating, Ventilation and Air Conditioning (HVAC) systems are the significant part of electrical energy consumption at the hospitals. The air-conditioning system is responsible for around 70% of total electricity consumption. Electric motors and lighting systems in a hospital represent approximately 19-21% of the total energy consumption. In this study, according to the detailed analysis on the lighting devices, electric motors and HVAC systems, the energy saving potentials and payback periods of these systems are estimated for a University Hospital.
