Specific and Non-Specific Evaluation of the Combined Environment of Color and Temperature

Abstract

Effects ofwaml color and cool color o ガ lthem 】 al sensation ' 「 ， the ， 「 impression ofhet − cold ' 「 and the I' impression ofwarm ・ cool 「 ， were discussed experimentally under the thermal conditions of20 and 24 ℃ in winter and 24 and 29℃ in summer ， Significant effect ofboth colors ori themmal sensation was shown under the 29 ℃ in summer ． The effect of colors on the ' 「 impression ofhot − coldl ' and the I' impression ofwarm − cool ' ， was 1arger than that on thermal sensation ． It was assumed that the former is more usua1 in the daily life from the viewpoint of attention ． The above observation showed that the alleviation effeet of colors from ' the psychological themmal load is large enough ．

<b>Actual conditions of residents’ cooling behaviors related to visual and auditory sensation and estimation of their effect on energy saving in Japan </b>

“…Nagano et al (1996) showed that environmental factors not thought to be directly relevant influence each environmental factor, and that specific evaluations of environmental factors on several scales influences evaluations specific to other environmental factors. Matsubara et al (2000) evaluated color conditions closer to everyday life, showing that the reducing effects of psychological load on heat through visual factors are greater with regard to cool colors on the high temperature side and warm colors on the low temperature side. In addition, a linear regression of the relationship between thermal sensation and temperature showed that adding visual and auditory factors decreased the gradient of the regression formula (i.e., the response to thermal environmental factors in relation to the increase in room temperature).…”

Effects of Visual Stimuli upon Thermal Sense under Air Conditioning in Summer

“…In addition, the research shows a clear inclination toward lower values once the ETF peak of 28-29°C is exceeded. Research by Matsubara et al [5], focusing primarily on psychological assessment, shows that, in slightly uncomfortable, warmer environmental conditions, an ameliorative effect on high thermal sensation was shown in the cool/ warm category as opposed to in the thermal sensation category in indoor settings. In addition, in research by Shimada et al [22], also focusing primarily on psychological assessment in indoor settings, the gradient of the regression coefficient was smaller for non-singular cool/warm impressions as opposed to singular thermal sensation impressions of heat.…”

“…In qualitative visual stimuli testing conducted by Matsubara et al [5], amelioration of the psychological influence (perceived high temperatures) was significant in relation to both hot and cold environments deemed slightly uncomfortable. The level of improvement engendered by fuller vegetation with regard to thermal environments was greater than that yielded by flatter vegetation cover [7].…”

“…In a study by Matsubara et al [5] focusing on psychological assessment in an indoor setting in a slightly uncomfortable thermal environment, the researchers show that lessening the psychological perception of higher temperatures was more greatly influenced by cooling colors in hot spaces and by warming colors in cooler spaces. In addition, research by Murakami and Shimomura [7] on psychological assessment on building rooftop settings indicates the possibility of visual elements engendering thermal senses due to rooftop greenery.…”

“…Research implemented by Matsubara et al [5] clearly indicates that the mitigating effects of psychological thermal load by means of orange or light blue colors in uncomfortable thermal environmental conditions are strongly influenced by cool colors on the high temperature side and by warm colors on the low temperature side. Matsubara et al [6] also add that visual or auditory factors, including green tones and water, clearly influence perception of thermal sensation as well as perception of comfort levels regarding heat.…”
