“…Sala, Alcamo, and Nelli [83] set out to demonstrate that there are substantial possibilities for lowering energy consumption in the European hospital sector, thereby contributing to a substantial reduction in CO 2 emissions. The primary objectives were incorporating energy efficiency strategies in the hospital sector, following current regulations, intending to enhance environmental quality and the ecosystem, and promoting sustainable natural resource management [83]. Innovative strategies such as HVAC for incorporating renewable energies into buildings have been combined with bioclimatic design to improve building management, energy efficiency, thermal comfort, natural ventilation, and daylighting.…”

A growing body of research shows that retrofitting practices can potentially reduce energy demand in hospital buildings and enhance indoor air quality. Yet, there is a lack of comprehensive reviews associated with green retrofitting practices in hospital buildings. This study aimed to undertake a systematic review of the past literature on retrofitting techniques used to improve indoor air quality and energy efficiency in hospital buildings, to identify barriers to its uptake, and to recommend solutions to identified challenges. For this reason, a systematic review was conducted for the published research from various academic databases. Findings showed a growing uptake of various retrofitting strategies for indoor air quality in hospital buildings. As a result, hospital management or building owners might consider addressing these challenges to facilitate the uptake and implementation of retrofitting practices in their facilities.

“…They concluded that 8% of energy reduction in hot‐humid climates may be achieved through building construction materials. Sala et al 31 investigated the building performance employing insulating envelopes. They recommended an overall heat transfer coefficient (U‐value) of the exterior building facades and roofs (0.32 W/m 2 K for external walls and 0.26 W/m 2 K for the roof) as low as possible to reduce energy losses and the summer overheating on exposed surfaces (southern, western, and eastern exposure).…”

Summary The worldwide environmentally friendly trend has focused the last decade on emphasizing the value of energy conservation and reducing the carbon footprint in buildings, achieving zero energy buildings. Presently, viable building techniques, in developing countries, are insufficient to achieve zero energy buildings. Thus, authorities should implement policies mandating new developments and renovations to establish “energy‐efficient buildings”; nevertheless, design solutions should be properly evaluated and assessed preceding execution. The conservation of energy without jeopardizing human comfortability is a huge challenge for any designer. Occupants are less interested in making a major investment to save some expenses over the next two decades, especially nowadays that energy is still affordable. Therefore, improved indoor environmental conditions are perhaps another important parameter toward energy‐efficient buildings. Through dynamic simulations, this study examines the energy efficiency and thermal comfort achieved by integrating retrofitting strategies in an institutional building in three different American Society of Heating, Refrigerating and Air‐Conditioning Engineers (ASHRAE) hot climate zones represented by three cities of Egypt (Aswan, Cairo, and Alexandria). The built‐up baseline model is validated using actual energy usage data. The validated baseline model is then subjected to local sensitivity analysis to determine the driving parameters influencing the building's energy demand. The study at hand focuses on a broader perspective on sustainability. With a multiapproach decision‐making methodology based on the most recent measures, the study highlights the outcomes through an environmental–economic assessment and indoor thermal comfort depending on experts' weighting, responses, and recommendations. The outcomes postulate that the implementation of reflective paints solutions would achieve the highest percentages of whole‐building energy savings with 21%, 19%, and 17% for Aswan, Cairo, and Alexandria, respectively, improving indoor thermal comfort levels.

“…As more than half of the energy consumption in healthcare systems is in hospitals [4,5], this study mainly focuses on data on energy consumption in hospitals. The implementation of sustainable energy systems is one of the main goals of the European Union (EU) energy policy, and experience in the hospital sector can be very useful in achieving this [6].…”

Energy use in hospitals is higher than in other public buildings, so improving energy efficiency in healthcare buildings is a significant challenge in this sector of engineering. For this, it is necessary to know the various determinants of energy consumption. Until now, the main factor affecting energy consumption in healthcare facilities studied in the literature was hospital capacity. However, the commonly used variables connected with hospital size and the number of beds do not take into account the medical activities carried out in these buildings. Assuming that energy consumption in hospitals is multiple and shaped by many factors that overlap, not only on an individual level but also on a higher scale level, this study devises a more integrated approach to its determinants. This study aims to investigate the determinants of electrical energy costs (EEC) and thermal energy costs (TEC) in Polish hospitals with regard to factors related to their size, work intensity and climate zones. The analysis was carried out using financial and resource data from all Polish hospitals for the years 2010–2019. The study used a multivariate backward stepwise regression analysis. In order to use climate as a moderating variable, a sample of Polish hospitals from 16 Polish NUTS 2 was divided into four climate zones. This article provides new empirical evidence on the determinants of electricity consumption in Polish hospitals related to their size and medical activity, taking into account climate zone as a moderating variable. The results of the analysis show that both electricity and heat consumption in hospitals are positively related to the number of doctors, beds and the number of medical operations performed. As expected, larger hospitals seem to use more energy. Moreover, there is regional heterogeneity in energy consumption in hospitals related to the climatic zone in which they operate. The conducted analysis shows that Polish hospitals located in the warmest climatic zone are characterized by higher energy consumption than hospitals in the coldest zone. It especially regards EEC in surgery hospitals. The warmer the climate zones, the higher intensity in terms of the number of surgeries, the higher EEC. In terms of nonsurgical hospitals, the influence of climate zone on EEC was not observed. Knowing the factors influencing energy consumption in hospitals can facilitate the correct adoption of an energy-saving strategy in the health sector, which is a reasonable response to climate change and supports a healthy and sustainable future.
