“…Meanwhile, the college buildings in Bandung show that their SET temperature is 1.41 o C higher than that of the residential houses in Wonosobo. This result is relevant to the thermal comfort finding in Wonosobo stating that cold regions have different thermal comforts than hot areas [21], [22]. The comfort zone in the residential houses is quite low, ranging from 27.93 o C to 21.63 o C which is different from that at the office or college buildings which are ranging from 22.2 o C to 29.0 o C. Due to the low temperature, the respondents who participate in the research conducted at the residential houses in Wonosobo feel more comfortable than at the office or college buildings in Jakarta or Bandung.…”

Thermal comfort may be evaluated from the thermal condition of residential houses and their occupants' satisfaction. This research evaluates the thermal comfort of traditional residential houses located in mountainous areas of Wonosobo, Indonesia. The evaluation is conducted based on the physical condition of residential houses and their occupants' satisfaction factors. A quantitative approach is employed to analyze the theory of static thermal comfort (Predicted Mean Vote/PMV) and that of adaptive thermal comfort (Actual Mean Vote/AMV). The research method is conducted based on a field study. The thermal condition is measured using 4 climate variables and 2 personal variables. Climate variables are air temperature, globe temperature, relative humidity and wind velocity. Personal variables are clothes and activity. AMV was based on thermal sensation from ASHRAE (American Society of Heating, Refrigerating and AirConditioning Engineers). The sensation thermal is very cold (-3), cold (-2), cool (-1), neutral (0), warm (+1), hot (+2), very hot (+3). The research has conducted a survey of 14 houses with 39 respondents. The research findings show that the comfort temperature is 24.47 o C within air temperature (T a) or 24.14 o C within T g or 24.17 o C within T o or 25.08 o C within T ET or 24.69 o C within T SET. These findings are compared to those previously conducted in Jakarta and Bandung showing that some differences are dealing with their comfort temperature. The other findings show that there are also some PMV and AMV differences of traditional residential houses located in the tropical mountainous areas.

Temperature and humidity are essential factors in analyzing a building’s thermal performance. This research presents the differences in field measurements of vernacular houses in coastal and mountain areas in Indonesia. Field measurements were taken for five consecutive days in four vernacular houses. The variables were measured at the beginning and at the peak of the rainy season. Analysis included a combination of graphic and descriptive methods. The research results show that the location difference between coast and mountain results in a relatively high difference in temperature (43.6%). The outdoor temperature in the mountain area is lower than that of the coastal area. The outdoor humidity of the mountain area is 0.69% higher than that of the coastal area. In the tropical coastal area, the outdoor temperature of the exposed-brick house is 0.94% lower than that of the coastal wooden house. The outdoor air humidity of the brick house is 0.89% higher than that of the coastal wooden house. In the tropical mountain area, the outdoor temperature of the exposed-stone house is 2.47% lower than that of the wooden house. The outdoor air humidity of the stone house is 0.4% lower than that of the wooden house. The outdoor conditions affect the indoor conditions of the respective houses. These microclimatic differences are influenced by micro-environmental factors, such as the density of surrounding buildings, amount of vegetation, and shading. The research shows that height difference is the most dominant factor influencing outdoor microclimate. Regional microclimate becomes the basis for determining the most suitable envelope materials in different areas. The innovative contribution of the work is, among other benefits, the identification of factors that influence the wellbeing of the buildings’ users in the researched geographical area and the analysis of the interaction of the external and internal environment of buildings. From the above facts, it follows that the results of this work can contribute to the development of prediction models to determine the type of cover, material, shape, and load-bearing elements needed to create comfortable and energy-efficient buildings.
