Abstract

General hospitals are used by many, including patients and visitors that are physically vulnerable to fine dust. Passive planning with the spatial structure of hospitals to cope with fine dust should be considered, in terms of public health, climate adaptation and sustainability. The purpose of this study is to compare the shape and volume of a lobby space that is advantageous in reducing the influx and influence of external fine dust in the main lobby space of a general hospital. In this study, ultrafine dust(PM2.5), which can adversely affect health, was targeted. Based on the morphological classification of lobby spaces in general hospitals in the preceding study, the spread of PM2.5 in lobby spaces was investigated through simulation. The lobby and the elevator hall through which fine dust can spread throughout the building were covered in the simulation. The results are as follow. If the other conditions are the same, the amount of PM2.5 reaching the elevator hall slightly decreased as the lobby area increased, and it significantly decreased as the height of the lobby increased. In the case of the same area and height of the lobby, when the X-axis length was longer than the Y-axis length, the amount of ultrafine dust reaching the elevator hall was less. It implies that the direction of the incoming air with dust and the spatial axis is closely related, and the follow-up study should be conducted including variables such as climatic conditions, direction of openings, and spatial axis.
