“…A comparison between the predicted and measured concentration is shown in Fig. 14. For zonal model, the root mean square error (RMSE) of calculation (1) is 0.25 and 0.19 for calculation (2). Even though RMSE of calculation (2) is small, it tends to overestimate the air quality ( Fig.…”

“…RMSE of calculation (1) and (2) are 0.22 and 0.35. The convective airflow along the wall is not considered and the contaminant concentration below the interface layer is always '0' with calculation (2). In order to avoid overrating the air freshness in the occupied zone, using calculation (1) might be better to predict the contaminant concentration profile of the room with DV.…”

“…An uncomfortable environment due to odor leads to a myriad of problems that contribute to the stress levels of patients, healthcare workers, and visitors [1]. Itakura and Mitsuda [2] surveyed nurses working in hospitals throughout the country, finding that more than 75% perceived a malodorous odor problem. Thus, the odor-related issues in hospital wards need to be addressed.…”

Displacement ventilation (DV) is known to provide high air quality and ventilation efficiency. With DV, a contaminant interface is formed in a room, and the air quality in the occupant zone below the contaminant interface height can be kept clean. This paper proposes a DV system to solve the serious odor problem in hospital wards. A vertical radiant panel that can be controlled individually is suggested as a complementary heating system. In order to study the influence of the panel on the displacement ventilated room, the temperature and contaminant concentration profiles were examined under different panel conditions: the distance between the panel and bed, height of the panel, surface temperature of the panel, and supply airflow rate. When the radiant panel was heated, it created a stronger plume than the human body, which produced contaminated air. When there was space between the radiant panel and bed, the contaminated air was locked up before reaching the ceiling. Personal exposure of a standing person was also investigated because the contaminated interface is generally lower than the breathing zone of a standing person with DV. The zonal model and improved zonal model were validated by a comparison of their results with the measured contaminant concentrations.

With limited medical resources, it is of great significance for countries all over the world to explore architectural design methods to enhance the value of medical facilities. Therefore, it is very necessary to carry out an extensive international comparison. In order to grasp the research trend of healthcare facilities in the world, this paper conducts co-occurrence analysis, cluster analysis, and trend analysis of the keywords of 334 English articles and 153 Japanese articles related to healthcare facilities published in important academic journals in the USA and Japan in the past 15 years. We not only compare the similarities and differences in healthcare facility research between the USA and Japan, but also explore the reasons for these differences. It is found that by introducing three kinds of value variables, such as time, space, and behavior, we can not only well explain the difference in the solution of healthcare facilities in the USA and Japan to reduce medical costs but also provide new ideas for architectural design to enhance the value of hospitals. Based on the above analysis, a conceptual framework of value-based design of healthcare facilities that combines the advantages of the USA and Japan is proposed in this paper.
