“…This supports the outcome of the probit analysis. Additionally, the slopes of the regression equations are comparable with the slopes derived from similar research: Indraganti and Bousaa estimated 0.216/K [16] and 0.283/K [17] in office buildings in Doha, Qatar; Katsuno et al [48] estimated 0.273/K in CL mode in residential houses in Kanto region, Japan; Ning et al [30] found 0.248/K in dormitory buildings in spring in Harbin, China; He et al [33] found 0.225/K, 0.269/K and 0.282/K for Chinese students of different origin in dormitories during summer in Changsha, China. However, there are instances when the sensitivity to the indoor temperature was observed to be higher (0.403/K in FR in Kanto, Japan [48]) or quite lower (0.187/K in FR and 0.106/K in CL in Kanto, Japan [49]).…”

“…Adaptive comfort has been investigated in offices in Qatar [16,17], Iran [18], Pakistan [19], in traditional houses in Nepal [20], in contemporary houses in UK [21], Singapore [22], Indonesia [23], Malaysia [24], India [25], China [26][27][28] and all over the world in various building types since developing the adaptive concept. The necessity to rethink comfort has been widely agreed on.…”

A summer field study was conducted in two university dormitories in the Tokai region of Central Japan. The study aimed at understanding the correlation between subjective thermal responses as well as whether nationality was affecting the responses. It was observed that nationality significantly affected thermal sensitivity and preference. The occupants’ acceptance for thermal stress was invariably above 90%. Despite the high levels of humidity observed, the multiple regression model showed that only the indoor air temperature was significant for explaining the variability of thermal sensation for both Japanese and non-Japanese students. The highest probability of voting neutral for university students in dormitory buildings in the Tokai region of Japan was estimated within 24~26.5 °C (by probit analysis). Japanese students were more sensitive to their indoor environment as opposed to the international students. The adjusted linear regression coefficient yielded from the room-wise day-wise averages were 0.48/K and 0.35/K for Japanese sensitivity and international sensitivity, respectively. In our study, the Griffiths’ model of estimating comfort temperature (or thermal neutrality) showed weak predictability and notable differences from the actually voted comfort. The neutral and comfort temperature observed and estimated in the study remained invariably below the recommended temperature threshold for Japan in summer leading to believe that that threshold is worth reevaluating.

“…According to the results, 50% of the occupants felt that controlling indoor trace gases (use of low emitting VOCs building materials and improvement of natural and mechanical ventilations in building designs) would ensure occupants productivity and health (Al Horr et al, 2017). Additionally, analysis of indoor air velocity in office buildings in Qatar, which is a critical factor in reducing build-up indoor air pollutants, showed that the indoor air velocity (0.0-0.05 m/s) in the current buildings did not meet the limits set by ASHRAE (0.18-0.25 m/s) (Indraganti and Boussaa, 2017). Further, the Table 5 Average environmental meteorology variations in the GCC countries .…”

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.
