Ventilation and noise in a cognitive day care centre: environmental quality analysis and design optimization study

Li W.,Du Z.,Wu Z.,Yu M.

In the context of epidemic normalization, it is particularly important to explore environmental health from the perspective of adaptation of patient pathological characteristics to achieve sustainable goals. Although recent studies have confirmed the effects of ventilation and sound on human health and revealed that improvement in the quality of patient recovery can be achieved by controlling the material exchange between people and the environment, it remains unclear in terms of the mutual drivers of intangible material (ventilation and sound) and patient recovery quality. This study establishes a link between the physical environment and the quality of rehabilitation by reporting on the ventilation and noise levels at a rehabilitation facility for people with cognitive disorders. Second, a successful design optimization technique based on the adaption of pathological traits is suggested. The Centre fails to fulfil the ventilation and acoustic criteria for indoor comfort, according to the findings of the real testing. The study procedure demonstrates that (1) enhancing the space's openness to unblock the airflow can only have its effect maximised if the layout is taken into account to accommodate the wind direction.; (2) the spatial scale is not the only factor affecting the sound quality of the environment; and (3) increasing the openness of the area can improve the quality of sound transmission and reduce noise in the area, but at the same time, it will have some impact on other areas.
