The aim of this paper is to analyze and quantify the average healthcare centres' energy behavior and estimate the possibilities of savings through the use of concrete measures to reduce their energy demand in Extremadura, Spain. It provides the average energy consumption of 55 healthcare centres sized between 500 and 3,500 m². The analysis evaluated data of electricity and fossil fuel energy consumption as well as water use and other energy-consuming devices. The energy solutions proposed to improve the efficiency are quantified and listed. The average annual energy consumption of a healthcare centre is 86.01 kWh/m², with a standard deviation of 16.8 kWh/m². The results show that an annual savings of €4.77/m² is possible. The potential to reduce the energy consumption of a healthcare centre of size 1,000 m² is 10,801 kWh by making an average investment of €11,601, thus saving €2,961/year with an average payback of 3.92 years.
本文旨在分析和量化西班牙埃斯特雷马杜拉地区医疗中心的平均能源使用行为，并通过采用具体措施降低其能源需求来估算节能潜力。文中给出了55个面积在500至3500平方米之间的医疗中心的平均能耗。分析评估了电力和化石燃料能源消耗数据以及用水和其他耗能设备的数据。文中对所提出的提高能源效率的解决方案进行了量化并列出。一个医疗中心的年平均能耗为86.01千瓦时/平方米，标准差为16.8千瓦时/平方米。结果表明，每年每平方米可节省4.77欧元。对于一个面积为1000平方米的医疗中心，通过平均投资11601欧元，有可能减少10801千瓦时的能源消耗，从而每年节省2961欧元，平均投资回收期为3.92年。
