Abstract
Background research is to see how many contemporary houses that much different from the Javanese house, contemporary house is usually attached to each other neighbor's house, do not have a yard, use half a stone wall, while the Javanese house has a large yard, far enough distance between the house and use a single wall stone. Objectives of this paper is to show natural differences in ventilation resulting from the use of materials, and types of homes are these different settings. Methodology used is to use CFD simulations to see how the difference and temperature difference. Using the measurement data base BMKG with winds measured at a height of 10m on the hottest and coldest months. Outcomes are the temperature and wind speed in Java proved to be more comfortable home. Summary The results proved that the traditional Javanese house more comfortable because it uses the hinge side windows, that make it easier for air to flow than the type of window (upper hinge) and one brick wall material further inhibit heat conduction than half brick wall. Keywords: natural ventilation, traditional house, contemporary house
Highlights
In this paper will discuss the comparison of natural ventilation on a traditional Javanese house that is in the town and at contemporary house
In this paper will discuss the differences in natural ventilation that occurs in traditional houses Kotagede and contemporary houses in Yogyakarta
According to Koenigsberger et al, thermal comfort is at 30-65% humidity, temperature dry bulb temperature (DBT) (21-30) under 100 ̊ C radiation in W / m 2 for men to wear was in temperate
Summary
In this paper will discuss the comparison of natural ventilation (air movement) on a traditional Javanese house that is in the town and at contemporary house. According to Fanger (1982) there are 6 factors that affect thermal comfort, 4 external and 2 of the human itself. Four of these factors are temperature ( ̊C), the average radiation temperature ( ̊C), humidity (%), wind speed (m/s), and two other factor is the activity (W/m2) and clothing (m2 deg C/W). In this paper will discuss the differences in natural ventilation that occurs in traditional houses Kotagede and contemporary houses in Yogyakarta. This refers to the materials used in both cases
