Heat Removal Using the Hollow Roof in the Javanese House
Architecture Department, University of Pembangunan Nasional “Veteran” Jawa Timur, Surabaya, East Java, Indonesia.
Ventilation plays a vital role in securing optimum air quality and thermal comfort in buildings. In fulfilling this need, it touches on a wide range of building design and ventilation performance. Early attempts to minimize ventilation energy loss frequently resulted in poor indoor quality and comfort problems. This paper explains about natural air circulation, indoor and outdoor air temperature and also air velocity on the hollow roof in Javanese house, which has a specific shape of geometry and how far that roof can reduce the heat gain in the building. This method using computational fluid dynamics based program have become available to predict airflow and pollutant transport throughout a space. These approximate the space by the grid system containing many control volumes or elements to which numerical equations of flow are applied. And, the result of this research, the cavity roof in Javanese house is able to add indoor air rate velocity, with the average value of 0.5 m/s, and giving the indoor majority cooling effect average value of 0.55 ° C.
Key words: heat removal / hollow roof / Javanese house
