Natural ventilation in traditional market building: Optimize air intake trough windcatcher components

This paper presents a study on one aspect of windcatcher implementation, to optimize air intake. This study aims to investigate the optimal aspect of natural ventilation in providing the required wind intake in the building to maintain the level of air intake in the room. The Indonesian Ministry of Health stated that each market must have 20% ventilation of the space and face each other. This study examines the most optimal strategy to obtain the ventilation intake, the method used is a quantitative method by comparing alternative variables. And the results of the comparison provide selected alternative elements that can be used to improve natural ventilation in traditional market.
