Passive designs of low-income housing with natural ventilation in tropical region

Abstract One of the goals of Sustainable Development goals is sustainable cities and communities. Making cities sustainable means creating career and business opportunities, safe and affordable housing, and building resilient communities and economies. One of the goals of sustainable cities and communities (SDGs 11) is by 2030, ensure access for all to adequate, safe and affordable housing and basic services and upgrade slums. Because the level of housing needs in Jakarta is quite high with limited land available, housing prices soar, this is inversely proportional to the high level of poverty in Jakarta so that many people make illegal and slum settlements to overcome the lack of funds they have. One way to achieve this target is to apply bioclimatic architecture to realize sustainable buildings with affordable operational costs so that the housing built becomes affordable. One way to save energy is to use natural ventilation. This paper presents a study of the application of bioclimatic architecture that can provide good air circulation created using natural ventilation. Natural ventilation is the process of exchanging air inside the building through the help of open building elements. This research is motivated by the current development of cheap apartment architecture in Indonesia which does not support good natural ventilation, people are starting to build something that benefits the market and ignores the importance of good air circulation. Therefore, the promotion and application of natural ventilation as part of low-cost energy consumption and avoiding the sick building syndrome with good air circulation, especially after the corona virus pandemic, is an important issue. The research method used is descriptive quantitative method, in the form of research with a case study and simulation approach. The result achieved is that the building can optimize natural ventilation evenly through orientation, building shape, opening design, etc.
