Purpose: Medical center has consumed the energy about twice the average value of building types. So, many countries have tried sustainability and energy reduction for building types through eco friendly certificate. This study investigate the eco friendly building certificate and energy performance certificate focusing in UK and Korea, and search the characteristics of status and services of certificates. Methods: BREEAM openbook and EPC open data have been studied in UK, and green building performance certificate and EPC data in korea have been analyzed. Results: UK has eco friendly building certificate focusing on healthcare, and EPC shows the standard, benchmark reference value, so lead to the CO₂ emission reduction. Primary health center and hospital show the higher value due to the dwelling unit. like a patient bed. Korea doesn't have green building certificate yet on healthcare, and EPC shows not the reference data, but the primary energy consumption. Korean cases just like in UK, clinic, public health, and outpatient center show the lower value compared to medical center, nursing home and general hospital. Implications: In Korea, it is needed for energy efficiency to have reference data information like a standard and benchmarking value for new design and construction.

Purpose: The medical care for children in Korea is needed more than previous time as the situation changed. However, there is a few useful research for the planning of the children's specialized public medical center. This study has been started to provide basic information for the planning of Korean children's specialized public medical center. Methods: Research and architectural documentation with field surveys to 5 of 14 children's specialized public medical center, data have been analyzed for characteristics of children's medical care. Results: The result of this study can be summarized into three points. The first one is that children's medical care can be categorized independent and integrated type according to connection with main hospital. Independent type has vertical or horizontal form from spatial composition. The second one is that spatial composition are allocated by typical service, outpatient, central, and inpatient ward zones. The outpatient zone has horizontal/vertical type, central zone has concentrated/separated type by spatial and treatment situation of medical center. The third one is that children's hospital school is the specific program and healing environment for children. Implications: It is necessary to make typical model for national wide medical care for children in Korea.

Purpose: As infectious diseases spread, hospitals have converted general wards into negative pressure isolation wards through remodeling. During the conversion process, there were limitations in converting the existing ward into an effective isolation ward due to its existing structure and mechanical system. To minimize these problems, this study proposes some general ward planning methods taking into account effective conversion to an infectious disease ward. Methods: Seven rapid conversion isolation wards have been analyzed in order to check their appropriateness as a negative pressured isolation unit. Then, general ward design planning methods that can minimize problems in rapidly converted negative pressured wards have been derived. Results: If general wards can be efficiently converted into negative pressure isolation wards, many isolation facilities can be secured effectively in a short period of time during a pandemic.

Purpose: The purpose of this study is to present basic data on installation location, functional connection, and arrangement to be considered when planning a neonatal intensive care unit in a certified tertiary general hospital. Method: Review the facility standards related to the neonatal intensive care unit, such as laws and guidelines, and select a Certified Tertiary General Hospital as a case hospital among the Neonatal Intensive Care Regional Centers designated by the Ministry of Health and Welfare to analyze the placement characteristics of major NICU components such as the location of the NICU installation, the connection of movement between adjacent facilities and functions, and the treatment room and accessory room. Results and Implications: NICU is a facility for critically ill babies among newborns and needs to consider more about infection and patient management compared to adult intensive care units, which not only install close to delivery-related facilities to enable immediate action after childbirth, but also divide the treatment room into open rooms and allow access to the attached rooms through dedicated corridors to minimize movement in the treatment room.

Purpose: It is important to note that the relative importance of risk factors should be identified to successfully complete the remodeling project of general hospital. Approached by analytic hierarchy process (AHP), the present study aimed to systematically evaluate the risk factors for remodeling of general hospital. Methods: The present work classified the risk factors of general hospital remodeling into four major categories including the requirements survey stage, planning and design stage, dismantling and construction stage, and maintenance stage. In addition, four sub-categories were derived from each major category factor. Furthermore, five major categories and four subcategories were selected to be considered from the perspectives of two stakeholders of contractor and constructor. The relative importance of the major and sub-categories factors was calculated using the AHP technique on the survey data collected from 49 respondents who participated in the survey study. Results: The results indicate that, the risk factor of requirements survey stage was found to be the most important risk factor to consider among the four major categories of factors. Also, insufficient preliminary investigation, design inconsistencies in architecture/mechanics/electricity, occurrence of safety accidents, and insufficient review of various equipment capacities and performances were found to have the highest priorities of each subcategory factor group included in the four major categories. From the perspective of contractor, the error in predicting the construction period was found to be the most important risk factor. The occurrence of safety accidents during construction was found to be the most important risk factor to be considered by constructor. Implications: The result of the current work should provide important insights and guidelines for the risk management activity that contributes to controlling the project time, cost, and scope required for general hospital remodeling.

Purpose: This study aims to evaluate the barrier-free environment at Fukui University's Bunkyo Campus, focusing on the mobility of students using manual wheelchairs. Methods: Data were collected on architectural plans, barrier-free facilities, and class schedules at Fukui University's Bunkyo Campus. Measurements included step heights, slopes, and the accessibility of classroom furniture for manual wheelchairs. Mobility was assessed by timing the movement between 19 classrooms used in the second semester of 2022 during breaks and summer vacation. Results: This study highlights that while Fukui University's Bunkyo Campus has some barrier-free buildings, significant improvements are needed. Issues include inadequate elevators, hand operated doors, and multi-purpose restrooms, as well as inefficient classroom's furniture layouts for wheelchair users. To enhance accessibility, future efforts should focus on reducing elevator wait times, automating doors, and optimizing classroom designs. Implications: The study indicates that Fukui University's Bunkyo Campus needs significant improvements in barrier-free accessibility. It provides foundational data for future detailed planning and implementation. Enhanced campus accessibility and better classroom designs are crucial for equal learning environments. Similar issues may exist at other Japanese universities, warranting broader investigation.

Purpose: The identification and quantification of indoor airborne contaminants, including bio-aerosols, particulates, and gaseous contaminants, are crucial for maintaining acceptable indoor air quality for hospital operating rooms (ORs). Laparoscopic surgery has become widely accepted for various surgical procedures due to its rapid recovery rate and the low risk associated with small incisions compared to conventional open surgery. The objective of this study is to investigate the indoor air quality in hospital ORs and to identify indoor airborne contaminants generated during laparoscopic surgery. Methods: Measurements of an indoor environment, including temperature, humidity and air quality, were performed in an OR before and during a laparoscopic surgery. Indoor airborne contaminants, including volatile organic compounds (VOCs), formaldehyde, carbon monoxide (CO), carbon dioxide (CO₂), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), suspended indoor particles, and airborne bacteria, were measured simultaneously. Results: The study determined that the concentrations of indoor air particles and airborne bacteria increased during the surgery but were within acceptable levels. However, the concentration of CO₂, reached a high level of 1,791 ppm due to the CO₂ gas required for maintaining the pneumoperitoneum during the surgery. Implications: The results emphasized the use of ventilation and filtration in a laparoscopic surgery room to lower the concentration of filterable and non-filterable contaminants.
