Abstract
This paper describes how far the thermal comfort in traditional Javanese house and its comparison with thermal comfort in a contemporary house.
Comparisons are made not based on field measurements, but only from computer simulations using the Ecotect programme. Results shows that the direction oriented to the south, clay tile roof material, one brick wall, ceramics tile floors, traditional house model, setting the building situated in a courtyard, showing maximum thermal comfort than the direction toward the west, concrete tile material, half-brick walls, ceramics tile floor, contemporary house models, setting the building is located to be very closed to a neighbor's house.
From the simulation results generated from the difference of traditional houses and contemporary houses quite thin. Both of the average annual temperature and the results of changing the orientation of the building. Differences in the presence of ventilation was also not significant. Differences due to aspects of the openings are also not significant. So that it can be concluded from the simulation for both traditional and contemporary get the same results. Only the thermal comfort the traditional house better than contemporary house.
Keyword: thermal comfort, traditional house, contemporary house.
1. INTRODUCTION
Comfort zone is an area in the bioclimatic chart shows the condition of air composition in thermal comfort. Thermal comfort is the combination of six factors (air temperature T, wind velocity, V, humidity-RH, the average temperature of the space-MRT, human activities-Met, clothing-clo) so it can not be represented by a single digit. As a
humid tropics dap [at achieved with a limit of 24 ° C <T <26 º C, 40% <RH <60%, 0.6m / s <V <1.5m / s, dress lightly coat, leisure activities quietly. In the humid tropical climate of high temperature rating
between 27ºC-32ºC was cool.
contemporary houses and traditional houses by looking at aspects of orientation, material
aspects, aspects of the openings.
Comparisons are conducted using simulation Ecotect not from field measurements.

RESULT
Thermal comfort for west orientation close window looks good for traditional house but look bad for out door.
Thermal comfort south orientation open window looks good in the traditional house but not good in out door .
Solar radiation for west orientation close window traditional houses 55.6 % and for west orientation close window kontemporer houses 61.5%.
Solar radiation for south orientation open window kontemporer houses 61.4% and south orientation open window traditional houses 64.6%.
Temperature distribution for traditional dan contemporary house about 6000hours at 28ºC.
CONCLUSION
From the simulation results generated from the difference of traditional houses and modern houses quite thin. Both of the average annual temperature and the results of changing the orientation of the building. Differences in the presence of ventilation was also not significant. Differences due to aspects of the openings are also not significant. So that it can be concluded from the simulation for both traditional and contemporary get the same results. Only the thermal comfort the traditional house better than contemporary house
RECOMMENDATION
The simulation is only processed in the solar radiation but ignore the wind speed. If the calculated wind speed may be much more get the difference in the thermal comfort
level of both types of buildings.
