“…The proposed analyses do not focus on either energy-saving or energy forecasting approaches in the U.S. healthcare sector. This work facilitates further analysis of US healthcare energy data similar to the one presented in [32], which investigates the impact of different factors on energy savings in healthcare in Spain.

Energy Consumption Analysis and Characterization of Healthcare Facilities in the United States

Healthcare facilities in the United States account for 4.8% of the total area in the commercial sector and are responsible for 10.3% of total energy consumption in this sector. The number of healthcare facilities increased by 22% since 2003, leading to a 21% rise in energy consumption and an 8% reduction in energy intensity per unit of area (544.8 kWh/m2). This study provides an analytical overview of the end-use energy consumption data in healthcare systems for hospitals in the United States. The energy intensity of the U.S. hospitals ranges from 640.7 kWh/m2 in Zone 5 (very hot) to 781.1 kWh/m2 in Zone 1 (very cold), with an average of 738.5 kWh/m2. This is approximately 2.6 times higher than that of other commercial buildings. High energy intensity in the healthcare facilities, particularly in hospitals, along with energy costs and associated environmental concerns make energy analysis crucial for this type of facility. The proposed analysis shows that U.S. healthcare facilities have higher energy intensity than those of most other countries, especially the European ones. This necessitates the adoption of more energy-efficient approaches to the infrastructure and the management of healthcare facilities in the United States.

Unidirectional flow air-conditioning systems are suitable for achieving indoor air quality required in high-performance operating rooms (organ transplants, cardiac surgery, aorta, orthopedic, burns, etc.). This paper analyzes indoor environmental conditions and technical and hygienic requirements for the design of heating, ventilation, and air-Conditioning (HVAC) systems for high-performance operating theatres. The main standards applicable to this type of operating rooms were compiled. Standard UNE 100713:2015, ASHRAE Standard 170-2017, and the European pre-norm EN 16244 were analyzed. A case study shows the lack of uniformity in design criteria and their ranges of values, which generates different design approaches. It was concluded that using these standards applicable to high-performance operating rooms leads to very different indoor environmental conditions for patients and medical personnel—air velocity profiles, air movement pattern, temperature, relative humidity gradients, and pressure stratification. Computational fluid dynamics (CFD) studies have been shown to detect areas of haven that favor microbiological load accumulation. In this way, it is possible to define cleaning protocols to attend these anomalies in a preventive way.

“…This includes, for example, energy management, which essentially comprises the optimization of electricity and heat consumption. This issue is particularly interesting for hospitals because it is possible to identify concrete cost savings by analyzing consumption patterns and deriving optimization measures (see, e.g., García‐Sanz‐Calcedo, Al‐Kassir, & Yusaf, ). This is also the case for water consumption (González, García‐Sanz‐Calcedo, Salgado, & Mena, ) and waste disposal (e.g.…”

Hospitals are major actors in the health care sector, and their duty is the safe treatment of patients. Thus, hospitals make an important contribution to the achievement of sustainability goals. However, they also have negative environmental impacts. Hospitals have difficulties responding to increasing environmental demands. The aim of this paper is to systematically delineate measures for hospitals' environmental management.We research EMAS-registered hospitals as pioneers in environmental management that have credibility through external validation. Based on 31 publicly available environmental statements, we analyze measures from the environmental programs. These measures are classified into general management approaches and measures that are related to input (energy, materials, and water) and output (waste, wastewater, and emissions).
