The need for building decent and affordable housing for the middle to lower is increasing. Housing design done by the developers often have a uniform design of the design especially interms of building shape, building area and site area. Due to land limitation, it now appears that residential buildings are built with series model, so that they only have one facade. This is due to the neighborhood buildings are attached to the wall of our building either right, left or rear side.The use of roof ventilation in buildings is one way to improve the natural ventilation in addition to cross ventilation. One of the factors considered in the context of energy efficient is the use of climate such as solar and wind. This study emphasizes in the utilization of wind for natural ventilation, and the aim is to reveal the qualities of simple natural ventilation in high density environments. Building density is one of the factors that affect the principle of micro-climatic conditions in the room. With the density and shape of residential buildings that have only one facade, it needs tactics to be able to take advantage of climatic conditions and shape of the roof in residential buildings. This research is also addressed to identify and analyze the performance of natural ventilation with simple roofs ventilation in a neighborhood with high density. This study was conducted by comparing several roof models with ventilation that found in the study area by applying a ventilation stack. This comparison is to know how effective the roof ventilation design that can increase the effectiveness of roof ventilation design that can improve the air movement inside residential buildings in high density environments.
