Investigation and Evaluation of Energy Consumption Performance for Hospital Buildings in China

Abstract

Energy use in hospitals is higher than other public buildings, so it is essential to investigate and evaluate its energy consumption performance to save energy. In this paper, a comprehensive investigation was conducted to study energy consumption of hospitals in China. The investigation results show that electricity use accounts for the maximum share in total energy consumption of hospitals, especially in south China. Improving air conditioning systems is the most direct and effective way for realizing hospital building energy savings. What’s more, a new evaluation system of energy-saving performance for hospital buildings was developed. This evaluation system could evaluate performance of energy use in hospital, find out the weakness of energy use, and provide improving suggestions. Furthermore, a kind of visual software was given by our paper, which can be used intuitively by practitioners to evaluate building energy consumption performance of a hospital.

An Integrated Method to Evaluate Sustainability for Vulnerable Buildings Addressing Life Cycle Embodied Impacts and Resource Use

“…In the present case study, 350 kWh/m 2 was assumed to be the annual energy consumption of a regular hospital building when calculating its operational impacts. The value was determined according to [79,80] considering bed number, floor area and climate zone. Table 6 presents the total embodied and operational impact results for each stage and process, whereas Table 7 lists the annual impacts of the 40-and 60-year service periods.…”

Electrical load prediction of healthcare buildings through single and ensemble learning

“…In recent years, various research focused on the energy analysis and consumption optimization in hospitals worldwide have been conducted, such as in the U.S. ( Bawaneh et al, 2019 ), China ( Ji and Qu, 2019 ), German ( González et al, 2018 ), etc. However, limited by the availability of reliable and fine-granularity data, most of them were descriptive analysis at a macro level.…”

Healthy Power: Reimagining Hospitals as Sustainable Energy Hubs

“…We consider average energy demand, assumed to be 41 MWh per day based on an annual average of 27 MWh per bed [69]. Total energy use consists of electrical and thermal demands which will vary based on climate and facilities.…”

“…Total energy use consists of electrical and thermal demands which will vary based on climate and facilities. Using an average value from previous studies, it is assumed here that 49 percent of the total energy use is electrical demand and the remainder is thermal [24,29,69,70]. There are analytical data available for medical oxygen in hospitals [49] and the demand for this scale is assumed to be 708 kg per day.…”
