“…For example, hospital humanized design refers to the privacy of patients and medical staff, and smart medical services will promote treatment efficiency. Compared with previous studies that largely concern individual indicators [25][26][27][28], this study proposed a complete system to demonstrate the systematicity and scientificity of green buildings. Additionally, rating methods, such as LEED, BREEAM, HKBEAM and GB/T 51153-2015, which serve as guides for determining the green hospital building performance pre-evaluation score standard, should consider regional characteristics to achieve compatibility.…”

“…Chamseddine et al temporally monitored the indoor air quality (IAQ) of hospitals to analyze seasonal variations and indoor-outdoor (IO) correlations [25]. Shi et al investigated energy consumption and building layout of 30 hospitals in the cold region of China to conclude energy-saving strategies in hospital building layouts for architects in the design stage [26]. Alzoubi and Attia measured sound transmission loss and insulation of two selected inpatient wards to evaluate Sound Transmission Class (STC), aiming to achieve acoustic comfort [27].…”

With ecological problems and energy crises intensifying today, greening is essential to sustainable development. Compared with other types of buildings, hospital buildings account for a relatively larger proportion of building energy consumption. In order to realize the rapid cycle optimization of a green hospital project in the design stage and improve the green grade of the building, a pre-evaluation Building Information Model (BIM) of green hospital building performance was established in this study. Firstly, the literature review and expert consultation established the building performance pre-evaluation index system for green hospitals. Then, BIM technology is taken to extract data needed for building a performance pre-evaluation system, and the Cloud Model and the Matter–Element Extension Theory are used to build models. The final green grade calculation is realized in MATLAB. Finally, the Maluan Bay Hospital is taken as an example to test the applicability and effectiveness of the proposed model. The results show that the green hospital building performance pre-evaluation model has advantages of simulation, cyclic optimization and fuzzy quantification, which can effectively guide the design and construction of a green hospital.

“…Carbon emissions is calculated by equation (14) and the parameters use the following values: EF is set to 0.7921 (Ministry of Ecology and Environment of the People's Republic of China, 2019); Based on the investigation of 30 hospitals in China ( Shi et al, 2021 ), the average energy consumption is set to 180 kWh/(m 2 •a). Assuming each patient accounts for 12 m 2 of inpatient ward, the energy consumption for one people in hospital is 3.95 kWh/day (or 3.12 kg/day carbon emission per people).…”

Gymnasiums, fitness rooms and alike places offer exercise services to citizens, which play positive roles in promoting health and enhancing human immunity. Due to the high metabolic rates during exercises, supplying sufficient ventilation in these places is essential and extremely important especially given the risk of infectious respiratory diseases like COVID-19. Traditional ventilation control methods rely on a single CO 2 sensor (often placed at return air duct), which is often difficult to reflect the human metabolic rates accurately, and thus can hardly control the infection risk instantly. Thus, to ensure a safe and healthy environment in places with high metabolism, a real-time metabolism-based ventilation control method is proposed. A computer vision algorithm is developed to monitor human activities (regarding human motion amplitude and speed) and an artificial neural network is established for metabolic prediction. Case studies show that the proposed metabolism-based ventilation control method can reduce the infection probability down to 4.3-6.3% while saving 13% of energy in comparison with the strategy of fixed-fresh-air ventilation. In the development of healthy and sustainable society, gymnasiums and alike exercise places are essential and the proposed ventilation control method is a promising solution to decrease the risk of COVID-19 while preserving features of energy saving and carbon emission reduction.

“…Muhamad et al (2022) also highlighted that daylighting in the hospital can improve the inpatient's well-being and hasten their recovery process. Another recent study suggested that a grid courtyard-type arrangement to helps to reduce the energy consumption to run the hospital building (Shi et al, 2021).…”

This paper presents the architects' and landscape architects' point of views on their original design intentions in designing and planning hospital courtyard gardens (HCGs) in Malaysia. Following a field observation, a semi-structured interview with two architects and two landscape architects was conducted. Additionally, the architectural design briefs for three selected Malaysian hospitals were obtained as secondary data for this study. The results revealed that the intended common design pointed out by the architects includes: i) Daylighting strategy; ii) Ventilation strategy; iii) Access to nature; and iv) Point of orientation. Landscape architects, on the other hand, are concerned with: i) Forest-like garden concept; ii) Natural and organic form instead of aesthetic appearance; iii) An escape place for relieving stress and; iv) A hang-out space for socialisation. This paper contributes to the understanding of how designers would think and determine the architectural plan and landscape design in achieving an optimal HCG design to meet the needs of the intended users.
