    In this research, we examined walking sense and dynamic displacement when floor structure and the deformation pattern of floor finishing structure changes. As the result, we got the followings: (1) We showed the influence of floor finishing materials is very greater than floor structure about walking sense, (2) We showed the deformation patterns caused by bending and compression are the another walking senses, (3) We showed that if floor covering material differs, hardness sense differs also in the same dynamic displacement.

    In the former paper, All Sky Model to estimate the sky luminance and the radiance distribution that authors had proposed on 2004 was improved, and the improved model was compared with former All Sky Model, CIE Standard General Sky and Perez model.
    Afterward, further examinations are repeated, and appropriate coefficients for the basic equation were derived applying the same structure of the basic equation, which can estimate high accurate sky luminance and radiance distributions of with small regional dependency.
    When the range of the combination of coefficients of the CIE Standard General Sky was considered too much, the limit turned out in the estimating accuracy by the model. Some ranges of the combination of coefficients were arranged a little, the re-improvement was tried, and the coefficients for more high accurate estimation were derived.
    In this paper, All Sky Model adjusted again is introduced.

    This paper describes the results of the field testing related to night soil treatment and the experimental studies focusing on passive heating of the two Japanese composting toilets. The followings were found. The mean content temperature of the toilets' fermentation tanks were kept less than 39°C, nevertheless the electric heaters continuously worked with electric power consumption of more than 200W under the condition of the makers' default and six person's use. According to the passive heating with highly calorific material such as used cooking oil whose input rate was 7L/week, the mean content temperature was kept almost beyond 45°C for 120h that means pathogenic organisms are inactivated by high temperature.

    In the conventional design method, it's difficult to estimate exhaust gas recirculation and short circuit that worsen thermal environment. It's preventing the improvement of air conditioning efficiency because thermal conditions become severe in anticipation of rising temperature caused to them. In this study, we create an air flow network model that predicts cooling characteristics of ICT equipment. We study how to predict machine cooling characteristics by analyzing this model. And we build a server rack which imitates the air flow system for machine cooling to carry out comparative evaluation between model analysis and actual measurement. Result of the comparison, the analysis captured the features of the actual tendency, especially average. Then, we made a simple prediction chart of machine cooling characteristics for air conditioning design.

    Compact city is thought as an important policy so as to cut down the urban maintenance management cost. But, the process of the urban compactization assumes to need a lot of cost. We should evaluate the compact city not only by the operation cost but also by the long term cost including the process of the urban compactization.
    In this case study, we created the 3 scenarios for the Nagaoka city toward the year of 2050, which are different in the degree of compactness, and evaluated them both in the compatcization period and the following operating period by the construction cost of urban facilities, infrastructure and all buildings of the target area including new built, retirement, and maintenance. The result is that the middle compact Polycentric scenario spend 19 years and the most compact Monocentric scenario spend 23years to recover the cost of compactization.
    We also calculated the administrative cost (construction and maintenance cost of the urban facilities, infrastructure and government buildings ,and compensation cost for moving) to realize the compact city of Polycentric scenario. The construction cost and compensation cost for peoples who move from suburbs to downtown could recover for 12yeas by saving the maintenance management cost and increasing property tax, if the compensation were for the values of the lands the moving people had in the suburbs before moving.

    In this paper, the electric power consumption of all electrified housing located in Hiroshima area was examined from the viewpoint of the relationships between the energy consumption for cooling and heating and the characteristics of houses and households. New separation method was developed to extract the electric power consumption for cooling and heating uses from the consumption for mixed uses, and the validity of the method was confirmed. Based on the consumption extracted, the actual condition of the consumption for heating and cooling was shown. Furthermore, to clarify the factors affecting heating and cooling uses, the Quantity Theory Cluster I was applied by using the characteristics of houses and households as explanatory variables.
    As the results, the partial correlation coefficient was higher in "structure", "age of householder" and "number of air conditioners" in cooling use, and "number of air conditioners" and "number of adults" in heating use. Therefore, it was clarified that the factors affecting the energy consumption for heating differed from them for cooling.
