Concept of Thermal Comfort in Flats in Pondok Bambu – East Jakarta

All apartment buildings in the bamboo hut use an artificial air conditioning system that aims to create thermal comfort in the building. This should be minimized by taking advantage of the potential of natural ventilation. Aims to achieve the ideal thermal in the building of flats in bamboo huts and how to design the window openings in the building of flats in bamboo huts, in order to achieve ideal thermal in the building unit. Therefore, a solution is needed to maximize natural air conditioning in residential spaces by increasing wind speed through the design of window openings which then affects air temperature and humidity. To create thermal comfort in the space, a study is needed on the performance of window openings and their effect on thermal comfort which then continues to design window openings that are suitable for thermal comfort needs. This study uses a qualitative method that refers to books and journals about thermal comfort and the effect of window openings on flats buildings. This research was carried out during the building period and one of the flats in the bamboo hut. With the theoretical basis of thermal comfort, building orientation, architectural elements, building materials, openings to thermal comfort, occupancy density, ceiling height, and the layout of flats which are the reference in this study with a data collection method in the form of searching for physical data by choosing the theory of thermal comfort and the influence of window openings on flats buildings that are in accordance with the research. So that it was concluded that the window openings with the type of hanging windows (top hung) and the ventilation owned by the residential spaces had less than optimal performance. The addition of window openings and ventilation dimensions can increase the speed and distribution of wind in the residential space so that the wind movement pattern does not only flow towards the ceiling of the space but can spread horizontally. As well as the use of a mix costume window opening type where the jalousie inlet combined with the swing window on the ventilation can circulate the wind optimally.
