The current need to reduce the high consumption of fossil fuel energy and the incidental high cost attached to it will allow users more control over their destiny in a sustainable manner within their immediate environment. It is also equally a good reason for designers to re-tool and re-engineer the role of natural ventilation in buildings, for the hot-humid tropical environment to a sustainable level. Indoor thermal comfort in residential buildings of the hot humid tropical environment has been an age long concern for designers and users within the region. In the past, this has led to evolution of peculiar designs and building systems, in response to the problem. This study adopted descriptive survey and ex-post factor case study research methods. The re-introduction of the native tropical architecture of this region, based on holistic development that integrates the individual into the environment, with the buildings interacting with the atmosphere as the air is more humid and this allows for more thermal stability, was found to be very effective and satisfying. From the results of this study, volumetric design principle, which is a combination of wind and stack (Bernoulli - Venturi effect) was found to be an effective design strategy for thermal comfort and effective passive ventilation for this residential building.
