Bandung takes an exemplary position in terms of Indonesian modernization and adaptation to the climate. However, these techniques seem to have been forgotten. Therefore lies the focus in this article on the passively designed architecture that was constructed during the colonization in the interwar period in Bandung. This research assesses arguments facing indoor thermal conditions and question alternatives for mechanical solutions. A comfort range has been set, aimed at the desired indoor climate in warm and humid regions. The results proved that passive design techniques can positively impact the thermal conditions, but that there are no passive solutions yet to reduce humidity. However, the allowance of fresh airflows through the building by means of natural ventilation has been proven effective, because it cools perspiration and thus increases acceptance of high humidity levels. Case studies provided evidence that passive design techniques used to be an integral part of modern architecture in hot and humid climates.
