A proper level of pressure should be controlled in the vestibule adjacent to the stairwell to prevent smoke-infiltration into the only available evacuation path. In addition, as building height is increased, more careful design of pressurization system is required under consideration of stack effect. In the present study, new numerical modeling technique and assessment procedure are proposed to find proper air-supply flow rates for the stair vestibule regarding stack effect. Also, this paper showed that VAV type of air-supply system is a good performance facility controlling pressure level of the vestibule, and numerical simulation model is practically useful design tool for setup of air-supply flow rates.

The physical conditions of pedestrian environments play a significant role in promoting health maintenance and encouraging daily walking activities. Previous studies of this generally focused on analyzing urban residential environments, dementia care units or general hospitals that support loitering behavior; however, the conditions of pedestrian environments in geriatric long-term care hospitals (GHs) should be considered differently from the aforementioned establishments. The purpose of this study is to evaluate pedestrian environments that support loitering behavior from a therapeutic environmental design perspective. A literature review and expert interviews with interior designers, caregivers and nurses were conducted to generate a checklist of pedestrian environment conditions in GHs; the checklist entailed five factors related to safety, accessibility, territory, nature and aesthetics and services along with twenty-two sub-factors incorporating the therapeutic environment perspective. Several design improvements were noted and in need of being reexamined and revamped to be more appropriate for elderly patients and their circumstances; current laws did not properly consider this safety factor. There were poor conditions in the outdoor pedestrian areas and the indoor pedestrian environments had numerous obstacles in place. Exhibiting a natural garden in the wards with natural light and open spaces are necessary to encourage elderly patients to want to walk, but these pedestrian-friendly conditions weren’t readily available in all hospitals. For future purposes, the comprised checklist of pedestrian environment conditions in GHs could be used as evaluation criteria for certifying GHs and potentially a useful reference for policymakers to strengthen regulations in creating more suitable recovery conditions for elderly patients.
