“…In addition, practical advice for energy conservation in hospitals includes focusing on lighting, heating systems, CHP, building fabric, and air conditioning [16,36]. Lastly, sophisticated surveillance and power management algorithms discover faults and recommend further enhancements [1][2][3][4][5][6][7].…”

“…A growing body of literature has also shown that the growing demand for electricity in hospital facilities is attributed to the demand for high-quality services and resource management [1][2][3][4][5][6][7]. For example, a wide variety of medical devices, ranging from large machines such as CT and MRI scanners to smaller ones such as nebulizers, can be found in healthcare facilities [5,7].…”

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.

“…Non-residential buildings account on average for 25% of the energy consumption for Europe's building stock, representing a heterogeneous sector compared with the residential [3]. Hospitals have large ecological footprints; they consume large amounts of energy and release potentially harmful pollutants [4][5][6][7]. In light of the ongoing health crisis, their role has never been more important.…”

Safeguarding affordable and energy-efficient medical services has emerged as a crucial necessity to sustain national healthcare systems, especially in view of the current pandemic. While a set of national standards and guidelines aim to set minimum energy requirements for the building facilities, more insight into the healthcare sector’s energy consumption in Cyprus is deemed necessary, since it is the 4th most energy-demanding sector per square meter in this country. This is the first extended research on energy consumption in healthcare facilities across the different climatic zones of Cyprus and the types of fuel favoured in each zone, which marks the novelty of this work. The findings of the study highlight that the coastal and inland climatic zones are the most energy-challenging regions, with more than 60% of the final energy needs covered by electricity. On the contrary, in the mountainous region, approximately 80% of the final energy needs are covered by oil and attributed mainly to heating purposes. The average national primary energy consumption of healthcare facilities was found to be 497 kWh/m2 in air-conditioned spaces. Therefore, this study highlights that the mean primary energy consumption per building surface is approximately 4 times higher than the national threshold for nZEBs; compelling critical consideration of intervention for their energy enhancement. Moreover, healthcare facilities in mountainous regions in Cyprus are heavily reliant on conventional fuel; an unreliable and highly polluting energy option. The work demonstrates the prominent challenge and high potential for energy retrofit of the examined facilities and their upgrading to nZEB-Hospitals, towards the endeavour to a climate-neutral energy transition.

“…In turn, the energy consumption of hospitals in Greater London (UK) ranges from 194 to 1270 kWh/m 2 /year [2], whereas the average values for Germany and Spain are approximately 270 kWh/m 2 /year [3,4]. In addition, a recent study on the CO 2 emissions derived from the energy consumption in Spanish hospitals estimates that the average annual ratio is 100 kg per m 2 of floor area [5].…”

Hospital surgical suites are high consumers of energy due to the strict indoor air quality (IAQ) conditions. However, by varying the ventilation strategies, the potential for energy savings is great, particularly during periods without activity. In addition, there is no international consensus on the ventilation and hygrothermal requirements for surgical areas. In this work, a dynamic energy model of a surgical suite of a Spanish hospital is developed. This energy model is calibrated and validated with experimental data collected during real operation. The model is used to simulate the yearly energy performance of the surgical suite under different ventilation scenarios. The common issue in the studied ventilation strategies is that the hygrothermal conditions ranges are extended during off-use hours. The maximum savings obtained are around 70% of the energy demand without compromising the safety and health of patients and medical staff, as the study complies with current heating, ventilation and air conditioning (HVAC) regulations.
