Abstract

Young people are a vital group in society who face various challenges during the important transition phase from age 15 to their early 30s. In this context, intensive attention and support are needed so that they can develop psychologically, socially, and economically. The Youth Community Center in Bekasi City is designed as a strategic solution to address these needs by creating a creative and collaborative space that supports the exploration of the interests, talents, and skills of young people. Given the rapid growth of the Bekasi City area, with its high level of urbanization, the emphasis on providing facilities that support creativity and innovation is crucial. With the Behaviour Architecture approach, the Youth Community Center is expected to stimulate social interaction and productivity so that it functions not only as a gathering place, but also as a catalyst in facilitating the potential and overcoming the challenges faced by the younger generation in Bekasi City. In the design of the Youth Community Center in Bekasi City using the Behavior Architecture approach, the data used consists of primary and secondary data, which is then analyzed using 5 aspects of the approach, including the functional approach, contextual approach, technical approach, performance approach, and architectural approach. The results of the architectural design aspects that have been analyzed then become guidelines for the next design process.

Abstract

Natural ventilation is widely applied in tropical residential buildings to improve indoor environmental quality and reduce cooling energy demand. However, increasing opening size does not always proportionally enhance ventilation performance. This study aims to experimentally determine the relationship between inlet opening variation and natural ventilation performance in a residential test room (6.0 m × 2.5 m × 3.5 m; 52.5 m³) oriented along the Southwest–Northeast axis. The investigation was conducted by measuring variations in indoor air velocity, temperature, relative humidity, and estimating the air change rate (ACH) under different inlet opening conditions. The inlet door opening was varied from 20% to 100%, while the outlet door remained fully open. Results indicate a non-linear relationship between opening variation and ventilation performance. Indoor air velocity increased from 0.09 m s⁻¹ at 20% opening to a maximum of 0.11 m s⁻¹ at 60%, then decreased at larger openings. ACH followed a similar trend, peaking at the intermediate configuration. Temperature differences remained minimal, confirming the dominance of wind-driven airflow, while relative humidity varied with airflow distribution and dilution effects. The findings suggest that moderate inlet openings may provide more efficient ventilation than fully open configurations in tropical residential buildings.
