Many issues have emerged more clearly than before in multi-storey residential buildings during quarantine and lockdown caused by the global pandemic COVID-19. Among these problems is the deterioration in people’s mental and physical health inside the home caused by quarantine and closure. This deterioration is due to inadequate passive ventilation, natural lighting, and the lack of green open spaces in and around traditional multi-storey residential buildings. Also, one of the most severe problems is the airborne infection transmission from a positive covid-19 person to others due to the lack of control in the entrance of buildings against an infected person. In this paper, we modified the shape of a traditional multi-storey residential building. Using Design-Builder and Autodesk CFD software, we create a simulation to compare the amount of natural ventilation and lighting before and after modifying the building’s shape. This work aims to increase the passive ventilation and daylight inside the building. Also, to achieve the biophilic concept to provide open spaces for each apartment to improve the mental and physical health of the residents. In addition, it protects the building users from infection with the virus. Through this study, we found that passive ventilation and daylight achieved more efficiency in the building that we have modified in its shape, which led to a 38% reduction in energy consumption. In summary, these findings suggest that by modifying the mass of the traditional multi-storey residential building with open green spaces provided for each apartment, the natural connection with the inhabitants of the building was sufficiently provided. Moreover, all this will significantly help improve residents’ mental and physical state, and it will also help prevent the spread of various diseases inside the homes.

在由全球大流行 COVID-19 引起的隔离和封锁期间，多层住宅楼中的许多问题比以前更明显地出现了。在这些问题中，隔离和封闭导致人们在家中的身心健康状况恶化。这种恶化是由于被动通风、自然采光不足以及传统多层住宅建筑内部和周围缺乏绿色开放空间。此外，最严重的问题之一是，由于建筑物入口处对感染者缺乏控制，导致 covid-19 阳性者通过空气传播感染。在本文中，我们修改了传统多层住宅建筑的形状。使用 Design-Builder 和 Autodesk CFD 软件，我们创建了一个模拟来比较修改建筑物形状之前和之后的自然通风和照明量。这项工作旨在增加建筑物内的被动通风和日光。此外，实现亲生物概念，为每间公寓提供开放空间，以改善居民的身心健康。此外，它还可以保护建筑物用户免受病毒感染。通过这项研究，我们发现被动通风和日光在我们对其形状进行修改的建筑物中实现了更高的效率，从而降低了 38% 的能源消耗。总之，这些发现表明，通过修改传统多层住宅建筑的体量，为每间公寓提供开放式绿地，充分提供了与建筑物居民的自然联系。而且，这一切都将大大有助于改善居民的身心状态，也有助于防止各种疾病在家庭内部传播。
