“…As identified by Humphreys [30], Brager and de Dear et al [31], and Kurazumi et al [7] [9] [10] [11] [12], the sense of expectation that the thermal environment of an indoor space will be more comfortable than the air temperature of an outdoor space has an effect. It is, therefore, considered possible that the neutral temperature for the indoor space will change.…”

When the thermal environment is under heated conditions, short-wavelength solar radiation shows a strong influence on the human body and the heat is accumulated in the human body. In order to demonstrate the effect of the short-wavelength solar radiation absorptivity of clothing on physiological temperature in an outdoor space, the relationship between the thermal environment evaluation index, ETFe, and the thermal sensory perceptions of the human body was investigated. A significant temperature difference of 2.7˚C was shown for an ETFe that was thermally neutral (neither hot nor cold). The effect of short-wavelength solar radiation absorptivity was strongly apparent in ETFe when direct solar radiation was strong and in warmer outdoor spaces. In an outdoor space where the effect of the sky factor and albedo was strong, the setting of the short-wavelength solar radiation absorptivity was demonstrated to greatly impact the estimation of perceived and physiological temperature. When interviewing subjects on clothing in an outdoor space, it is essential to obtain the hue of clothing.

“…There was a study showing that acclimatization did not have a significant difference on the psychological reaction when the subject could not tolerate the environment if the temperature was greater than 40˚C [4]. In addition, Thai people from a tropical region perceive an ETFe of up to approximately 35˚C to be a moderate thermal environment but cannot tolerate the temperature of approximately more than 40˚C [5] or 3˚Chigherthan normal body temperature or normothermia = 36.8 ±0.7 °C.…”

The purpose of this research is to study and compare outdoor spaces with different cooling devices in the tropical climate of the city campus in the CBD of Bangkok, Thailand. The study aimed to find the most comfortable outdoor space on a green campus, referring to the UI Green Metric World University Ranking indicators, with a case study of Chulalongkorn University, which is a wet, tropical area in the city center. The ratio of the area on campus that is covered with planted vegetation (lawns, gardens) is provided as a percentage of the total site area and is the subject of comparison. In particular, the microclimate seems to be an important criterion of the physical design features of an outdoor space: a) with cooling devices, such as shading and fountains, and b) without cooling devices, such as pavement and open lawn. The cooling effect of these devices, which are evaluated by the thermal comfort measurement results, responded according to the tropical environment of the campus. This study explains the micro/macroclimatic effects of the landscape features. The survey measured the meteorological conditions of the outdoor spaces. The study determined that the shortwave solar radiation and longwave radiation from different materials should play an important role in a new paradigm for green design and planning.

“…Kurazumi et al [18] [19] [20] demonstrate the influence of an outdoor thermal environment on the human body for the influence of a tropical climate with strong short-wave length solar radiation on the thermal sensation of the human body as the evaluation axis. It clarifies that in tropical areas where the effects of nighttime cooling cannot be expected, the effect of long-wave length thermal radiation is strong in the shade of objects made of materials with high heat capacity, and the effect of improving the thermal sensation of the human body through shade is low.…”

In a summer outdoor space, the influence of shortwave length solar radiation on the human body is strongly apparent, heat is retained in the body, and the risk of heat disorders such as heat stroke increases. To avoid this, it is essential to seek shade to avoid the influence of shortwave length solar radiation. In addition, natural ground surfaces such as green spaces and water surfaces are useful in reducing the air temperature. It is indispensable to consider climate mitigation effect of outdoor space. The purpose of this study is to clarify the influence of the thermal environment of an outdoor space on the human body in rural and suburban regions where paddy fields remain. Subject experiments were conducted to examine the relationship between the thermal environment evaluation index enhanced conduction-corrected modified effective temperature (ETFe) in an outdoor space and the physiological and psychological responses of the human body. Experiment sites were selected with consideration for the natural ground surface such as bare ground where the surface is gravel or soil; paved ground such as concrete, asphalt or blocks; green areas covered in plants; and water surfaces, as well as the sky factor due to buildings or trees etc. and the proportion of the solid angle of components of greenery and water etc. comprising the solid angle of the total celestial sphere. A ground surface feature with a high heat capacity may promote sensation of hot and deteriorate the thermal sensation. A landscape of thick vegetation with a high green factor may have a strong feeling of confinement, which can make it somewhat hot and somewhat uncomfortable thermal environment due to the sense of stagnation.
