Abstract:
Global warming has triggered weather anomalies that have extended the duration of human activity indoors. This has led to a surge in the use of artificial lighting and ventilation. This phenomenon has a significant impact on low-rise house typologies located on narrow urban plots, where limited site area and physical obstructions from surrounding buildings often create dark and stifling spaces, ultimately leading to energy wastage. This research aims to formulate effective passive design strategies to maximize natural lighting and ventilation in order to achieve energy efficiency on constrained sites. This qualitative study employs a descriptive-analytical approach using a single-case study method. Data were collected through literature reviews and direct observation of the design implementation in a three floors house in the urban area of Tangerang. The research findings formulate eight passive design strategies that have been implemented in practice, categorized into vertical and horizontal scopes of influence. These eight strategies demonstrate that energy efficiency in urban dwellings on narrow plots can be achieved through precise architectural engineering based on the performance evaluation of the built environment.
