This paper aims to present and assess the prospective environmental feasibility and efficacy associated with the integration of Direct Air Capture (DAC) technology into diverse design methodologies within contemporary architecture. The primary focus of adjusting the flow of the chemical process through various design parameters will be elucidated for the hypothetical application into buildings. This chemical process involves the scientific method of utilizing the hollow-tube fibers with potassium hydroxide (KOH) as the primary carbon absorbent, where the CO2 contained ambient air is absorbed in fibers and converts into liquid state of K2CO3 + H2O. This carbon dioxide will be captured and transported through building services, for the future utilization and storage. This research highlights that the chemical flow of the DAC process can be effectively implemented through three distinct architectural design factors: façade modules, and an add-on mechanism for existing buildings and infrastructure. Despite the early introduction of DAC in 1999, its current status remains at the research level and cost demanding, yet to progress beyond industrial applications. However, the paper argues that when broadly applied in buildings powered by renewable energy sources, DAC integration has the potential to mitigate the escalating CO2 contamination, through ensuring buildings to capture more carbon than they emit, mimicking the principles of photosynthesis from the nature. Thus, the research prioritizes in opening a vision for new concept of sustainable architecture, directly responding towards the global climate issues, and acts as a first stepping stone beyond carbon reduction, towards carbon-capturing architecture.
