The dynamics of development in strategic areas Kauman kampung Surakarta impact on the comfort level of the building habitable conditions including thermal performances. It is shown that the simulation analysis performed on two houses of
Ketib (Khotib) with different changes in the pendapa space, the pendapa with the characteristics of open and closed spaces. Analyses were performed with Autodesk® Ecotect Analysis software with object location Kauman, Surakarta (Latitude: -7.6, Longitude: 110.8, GMT +7.00, 95 m above sea level) based on data
from BMKG/ Meteorology Climatology and Geophysics Council Surakarta on 10m
height , the area that simulated : pendapa (a living room in traditional javanese
house usually located in front of the house or the south of the house), dalem (the
main room in the javanese traditional house), senthong (the sacred room in the
javanese traditional house) , thermal conditions on the hottest day of the summit (4th
September) thermal conditions at the peak of the coldest day (7th July).
Study changes in the region Kauman space is a continuation of previous studies that implements the method of with reference to the concept of green eco-tourism. Results of the study will be the findings to determine the development strategy in the region Kauman Ketib’s house.
Keywords: strategic city, Ketib's houses (derived from the word Khotib =someone who lead pray in the mosque), thermal comfort
1. Introduction
This study is a serial study, the first research focused on: to formulate the
spaces, which aim to know what types of buildings that are the most
comfortable in terms of the air flow aspects and the thermal aspects.

Part of
According to Satwiko (2008), the thermal comfort in the humid tropical areas is at a temperature of 24˚C <T <26˚C, 40% <RH <60%, 0.6 <V <1.5 m/s, with a layer of lightweight clothing, and the activities are relaxed and calm.
2. Methodology
The method used is to perform simulation EcoTech 2011 v.5 on 2 cases of buildings
in Kauman batik kampong tourist which case 1 Fa’idzun (khotib / Ketib / prayer leads
Anom) facing south with an open pendapa in comparison with the case of 2 khotib /
Ketib / prayer leads R. Ngt. Pringgokusumo (Ketib Aroem) facing north with closed
pendapa.
3. Results and Discussion

Case 1 the house no 12 Fa’idzun’s (ketib Anom) house south orientation building, closed pendapa

Perspective
Figure 4. The plan and perspective Fa’idzun’s house (Setyaningsih 2013)
Direct solar that absorb by the building in case 1 was approximately 3000 -1800
W/m2 in a year.
In the pendapa and dalem wind speed ranges were from 0-0.5 m/s around the
pendapa and dalem about 2.5-3 m / s.
The thermal comfort was found in the pendapa (25.5ºC) but in dalem the
temperature about 30-33 ºC.
Figure 6.Air flow rate on Case 1
Thermal comfort was found in the front of the dalem (24ºC), the senthong 18 ºC, the
pendapa 32 ºC.
Case 2 the house no 40 R. Ngt. Pringgokusumo(ketib Aroem)’s house north orientation building, opened pendapa

Direct solar that absorb by the building in case 2 was approximately 1.100 -
168.000 W/m2 in a year.
Wind speed about 0-0.5 m/s at the pendapa and at the dalem was about 0.5-1 m/s.
Figure 11. Air flow rate on Case 2 Figure 10. Distribution of direct solar in a year
Thermal comfort found in the dalem (24ºC) while the temperature of pendapa was
28ºC.
Thermal comfort found in the dalem was 23.2ºC and the pendapa about
28 ºC.

4. Conclusion
Case 1 Case 2
Direct solar that absorb by the house in
case 1 approximately 3000 -1800 W/m2 in
a year.
dalem the temperature about 30-33 ºC.
In the coldest day, thermal comfort found in
the front of the dalem (24ºC), the
senthong 18 ºC, the pendapa 32 ºC.
In the hottest day, thermal comfort found
in the dalem (24ºC) at a temperature of
pendapa 28 ºC
In the coldest day, thermal comfort found
in the dalem 23.2ºC and the pendapa
about 28 ºC.
Direct solar in the dalem gained Case1 more than Case2. Ideal wind speeds more in
the dalem Case1. Thermal comfort in both the coldest and hottest day, in pendapa
Case1 more comfortable.
Recommendation obtained is not an effective use of the open pendapa to obtain
thermal comfort of the building. It would be better if that is used as a covered pendapa.
These changes may be due to changes in the surrounding environment so that the
open pendapa becomes less comfortable than closed.
