“…As can be seen from the studies that used this method, it has been used to obtain an optimum solution for the problems, which are occurred with the application of new energy sources, such as optimum operating cost and strategy, evaluating equipment performance. This method was not only used based on a single objective, which is generally minimizing total annual cost [20], [19]- [24], [31], [34], [36]- [38] and [39], but also it was used based on multi-objective such as ton minimize the costs and to maximize demand satisfaction [30], minimizing the total annual carbon dioxide emissions/ minimizing the global environmental impact/minimizing the costs [25,32], total cost of system and CO2 emission [33], the trade-off between the economic and environmental aspects [27].…”

“…CHP and CHCP applications in healthcare facilities generally are working depending on the grid electricity system and natural gas as fuel input. In many relevant studies, various solution methods have been applied for the purpose of obtaining minimum operating cost, optimal operating method and ensuring maximum efficiency for these systems, whereas some studies have proposed to put forth a framework related to comparing of application of these systems for healthcare facilities and equivalent buildings such as hotel, office and shop center [39,55,56,57,58].…”

Healthcare facilities are one of the main buildings that have great energy consumption. This situation reveals the need for good energy planning and management based on the principles of energy efficiency as well as cost-effectiveness for these facilities. In this context, a literature review, between 2006 and 2018, on energy applications realized for healthcare facilities, such as energy planning, energy management, energy efficiency, selection of alternative energy technologies, using of different energy sources, energy renovation/refurbishment activities have been executed. A Systematic Literature Review (SLR) method was used, where research questions and searching stages were defined. This review study has been conducted on energy and healthcare relevant keywords in the Scopus database. After a thorough analysis of the papers retrieved from the Scopus database, a total of 176 primary articles has been categorized according to their relations with energy efficiency, energy planning, and energy management. In each category, major research issues, findings, and important aspects have been analyzed and reported. With this analyzing, developments in the existing literature have been put forth and potential areas for future research have been suggested. Findings pointed out that energy-related studies for healthcare facilities are between trending topics. For ensuring minimum cost and maximum utility for energy, the articles using the solution methods of operations research and engineering economics regarding alternative energy applications are especially popular. As a solution method for energy problems, Mixed Integer Linear Programming (MILP) is widely used in 20 studies. On the other hand, cogeneration and trigeneration applications, which minimize energy costs and waste energy and are very suitable for large buildings, are the most frequently studied alternative energy applications with 83 articles.

“…The constant human activity that takes place in these buildings and the numerous people who are working or moving into these structures make proper energy management a necessity. Furthermore, energy management in hospitals is an important factor since its mismanagement leads to an increase in operating costs, a negative environmental impact, and a decrease in competitiveness [7]. However, the medical devices used in intensive care units (ICU), surgery rooms, imaging units, and furnaces also require large amounts of energy for smooth functioning.…”

Purpose: This paper analyses the functioning of a solar panel system at King Hamad University Hospital (KHUH), indicating its part in enhancing sustainability and cost-efficiency. Due to the increasing demand in renewable energy, this study illustrates how healthcare facilities can minimize operational costs using solar energy. Methodology: The study details the integration of solar panels into KHUH’s infrastructure, importance their potential for energy generation. It encompasses a methodical investigation of the project's technical, economic, and environmental scope, aligning with the hospital's commitment to responsible resource management. Findings: The study reveals that KHUH's implementation of solar panels much reduces electricity payment, in this manner present substantial cost savings. It also enhances the hospital's energy safety and leads to an important reduction in greenhouse gas emissions, reflecting its commitment to environmental impacts. Originality: This paper's originality lies in its determined inspection of solar panel integration in a hospital, underlining in cooperation economic and environmental profit. It contributes to the role of renewable energy in healthcare, showcasing KHUH's original role in sustainable and efficient resource management in the medical sector.

Subsidy and social systems should be designed to effectively promote, for example, the introduction of a mechanical system. For an effective subsidy distribution, developing evidence-based decision-making methodologies is essential. We developed a tool that minimizes an objective function includes economic costs, environmental cost, and disaster risk to determine the amount of energy distributed by the equipment when installing in hospitals against disasters. Open data available on the Internet are used as simulation values herein. This simulation model optimizes six design values using a genetic algorithm based on the values (business site area, demand for heat and electricity, and maximum allowable loss) input by customers for their construction and visualizes the total cost. The tool allows to quantitatively assess the changes in the initial and running costs owing to equipment installation and the avoidable losses related to CO 2 emission reductions and disaster risks. In addition, the net present value (NPV) can be calculated using the obtained values for initial and running costs, thereby allowing to clearly estimate the return on investments after equipment installation. The opportunity profit can be calculated based on the difference between the NPV after 15 years assuming no risk and with disaster risks. A method to set this opportunity profit as a calculated subsidy amount is proposed herein. Decision support can be provided via these simulations to the customers and government subsidy system design engineers.
