Various researches highlight that indoor air quality affects performance of workers in offices. Although good indoor air quality improves work performance, it also increases energy consumption. In this study, we achieved a field survey in a real office in order to investigate the relationship between thermal environment, productivity, and energy consumption. In addition to the monitoring of indoor environmental quality and energy consumption, subjective experiments were conducted. In order to evaluate subjective performance, workers and students responded to questionnaires, and to evaluate objective performance, students simulated three types of office works. By calculating room temperature and worker's subjective performance, we demonstrate the correlation between room temperature and worker's performance (R2=0.22, p

The SHIMODERA-NITTO Improved Dwellings were built by a slum clearance program before World War II. They are the only buildings that still remain. The object of this study is first to place these dwellings as the historically important program in urban planning, and second to analyze the drastic changing of living space by extension, called "DASHIYA". This study made it clear that this dwellings were a model of housing policy in Osaka before the War, and that under the special restriction dwellers extended house for the purpose of improving the small house to adapt to changing of life style.

In view of the rapid large scale development of underground in the central big cities, especially around terminal stations, evacuation experiments have been conducted with 79 subjects using an underground shopping mall near Tokyo Station actually in service after business hours. Four groups of 20 subjects started from different locations and time to “escape” from any of emergency exits was measured for each subject. 12 out of the 79 subjects wore elderly simulator to compare evacuation behavior of elderly and that of younger people. The evacuation behavior was also monitored by video cameras and escape route of each subject was reproduced afterwards. Five experiments were conducted using the lighting conditions and layout of emergency exits as parameters. The starting point was changed from experiment to experiment, not making any subject repeat similar selection of escape route. The shopping mall is composed of grid of passages, and is installed with escape route sign lights on every passage according to Fire Service Law. In every experiment, it was observed that considerable portion of subjects did not select right passage toward nearest exit at intersection nor passed over right exits. These are not compliant with widely accepted assumption for deterministic modeling of evacuation in mall-like facility. Factors dictating the probability to select right passage at intersections and that to recognize emergency exit are analyzed from the experimental data.

This study aims at the verification of the hypothesis on the polarization to mega-city regions and urban divide with focus on gentrification in the Special Wards of Tokyo, Japan. Following the extensive literature review on gentrification, firstly, we analyzed the situation of gentrification and urban divide at the Ward level and applied the cluster analysis to further discuss the situation at a micro-level. Secondly, we shed light on the relation between local government policies on urban regeneration and gentrification in Tokyo and found strong relationship between them. The acceleration of the concentration of wealth to Tokyo is clearly observed in Japan since 2000s. In particular, the polarization of wealth as well as the highest income class to the central part of Tokyo is ever accelerating these days under the neoliberal urban policies. In the urban scale analysis in the Special Wards of Tokyo, situation of gentrification in the central city areas are obvious these days. On the other hands, the concentration of lower income households is observed in inner areas. Younger people of lower income tend to live in the west inner city areas while aged people with lower income tend to live in the north and east inner city areas. As a result, the urban divide in both social and spatial terms are observed. Yet, in inner city areas middle-class gentrification through the development of high-rise apartments/condominiums are also actively advancing and thus micro-level, mosaic-pattern spatial disparity is formed in inner city areas of Tokyo. Based on the analysis on the land use and urban redevelopment policies of Tokyo Metropolitan Government and the City Master Plans of 7 selected Wards (cities), it is found out that urban development/redevelopment policies at the Ward level are classified to the following 3 types: ‘large-scale urban redevelopment oriented type’, ‘incremental improvement oriented type’ and ‘hybrid type’. Wards located in the city center and its vicinity belong to the large-scale urban redevelopment-oriented type, while other Wards belong to other types based on their situations. The large-scale urban redevelopment-oriented policies naturally have high affinity to neoliberalism urban development/redevelopment policies. It follows that urban development/redevelopment polices in the Wards in the city center and its vicinity promote gentrification in those areas and thus bring about urban divide in Tokyo.

Tokai village is a home to the first commercial nuclear power plant in Japan. In Tokai village, Nuclear Power Plants are directly adjacent to residential districts. This study investigates the context of this situation by looking back around 1960 when the plants were built and clarifying the urban planning, development project ideas, and decision-making processes that were involved in the planning. The main findings of this analysis are listed below:   1) When the location of Japan’s first commercial nuclear power plant in Tokai village was being examined in the summer of 1959, the chairman of the Nuclear Power Commission, Nakasone Yasuhiro, attempted but ultimately failed to negotiate an act on nuclear power urban planning with the National Diet of Japan. To compensate for this lack of law, the Ibaraki Prefecture devised a basic plan for the construction of the plant in Tokai. However, Ibaraki Prefecture, which had designated Tokai as the site of the atomic center, completely watered down the intended regulations. 2) The Tokai Atomic Urban Development Prospectus was drafted in 1957, which was the document that the development project for the construction of the nuclear power center in Tokai Village. The Tokai Atomic Urban Development oversaw the development process, acquiring and managing sites for the companies advancing into Tokai Village, and managing the construction and administration of shared company facilities. 3) As for the location of the companies advancing into Tokai Village, sites close to railway station and national highway were secured to facilitate convenient transport. In addition, sites close to the Japan Atomic Energy Research Institute (JAERI) were designated for employee residence housing. When the construction of the Tokai Power Station was approved in December 1959, the companies advancing into Tokai Village gained property rights over the sites it had acquired and managed, and the development of the village for the operation of the Tokai Power Station officially commenced. 4) Japan Atomic Industrial Forum (JAIF) Inc. drafted the development plan, founded Tokai Atomic Urban Development, acquired and managed company sites, and constructed shared facilities. The Ibaraki Prefecture involved JAIF in making decisions on city plan of Tokai Village. Consequently, city plan was created in which the plan of JAIF was respected to the utmost, and residential area development proceeded around the site of Tokai Power Station.   The involvement of the JAIF in urban planning in Tokai village, together with the above-mentioned spirit of collaboration, led to the creation of a problematic plan, wherein locations around the plant were not zoned as industrial areas, the Tokai Power Station site was not zoned at all, and residential areas were surrounded by industrial areas on three sides.   The decision not to regulate the development of the areas surrounding the nuclear plant site has led to the current difficult situation whereby no regulations have been enacted to govern the advancing development.

This Paper shows the kyoto's role in forming the Ancient Shrines and Temples Preservation Act(1897) was decisive. To help recover Kyoto's economy, since 1881 Kyoto had been trying to preserve old edifices in its shrines and temples as its symbols. But for lack of sufficient fund, Kyoto began to carry on a campaign to form a national law to preserve those old edifices; Kyoto even proposed a preservation bill referring to the ones abroad and ask other prefectures to join the campaign. Kyoto's propositions were introduced in some articles of the Act.

In constructing a 256-m-high skyscraper on a reclaimed land, there are two problems awaiting solution; one is negative friction of piles due to consolidation settlement of alluvial clay layer under the reclaimed soil layer and settlement of diluvial clay layer locating deeper than the bearing stratum of the building. These were handled in conducting subsurface exploration, foundation design, study on construction methods and construction work at the site controlled by measurements. Land settlement due to construction of a building should be estimated not only by evaluating increase in load and volume compressibility but also by considering 1) changes with time in ground-water table during excavation work and 2) load re-distribution effect due to rigidity of superstructure as a whole

The Study clarified how neighbourhood amenities are located following their spontaneous emergence in a suburban residential area developed through land readjustment projects. The main findings of the Study are listed below.1) The scope of the development of neighbourhood amenities by a private developer is limited as the emphasis is placed on profit-making amenities.2) In a situation where the locationing of neighbourhood amenities is left to spontaneous emergence, there is a tendency for such amenities to be clustered around a railway station.3) The unit number of neighbourhood amenities shows secular changes while reflecting the characteristics of individual zones.

Recently attention has been focused on countermeasures against microorganisms such as viruses and microbe, in connection with pandemics of new forms of influenza or SARS, and the occurrence of bioterrorism. Also, in pharmaceutical or food production facilities, a high standard of internal environment of the facility is required, including countermeasures against microorganisms. These countermeasures from the facility point of view include partitioning of work zones (zoning), and cleaning the air using HEPA filters. However, when workers/researchers are working within a facility, dispersion of dust or adhering microbe brought in from clothes, etc., cause pollution of the air. In this report, the sterilization performance of weak acid hypochlorous solution used as the chemical substance was verified. In addition, the sterilization performance in an actual space varied not only with the chemical substance used, but also with the condition of the room, the air conditioning system, the method of spraying, etc. Therefore, from the above sterilization performance tests using chemical substances, the raw data required for a computational fluid mechanics (CFD) model were derived. A method that enables the effect of the chemical substance to be predicted under various conditions was investigated, and the results are reported.

This paper aims to clarify the GHQ military disposition which changed rapidly and nationwide location of Dependent Housing (army family house) and the numerical transformation process in the occupied Japan by the U.S. document. Soon after Japanese people had begun to convert the building stock which was left after WWII, occupation forces were stationed in each place and began the requisition. The occupation forces requisitioned the building which was judged to be available locally in the short term and they rehabilitate it and used. D.H. was built approximately 12,000 houses, and about 70% was built newly in Japan. The construction of D.H. was hurried, and because material was short, it was often supplied in black markets. And, by grasp of the numerical transformation process of D.H., the different requisition situation and situation of distribution became clear in each district. 9 districts where there were dependents more than 200 households as of June 1, 1948 are as follows in decreasing order. Tokyo, Yokohama area, Tachikawa, Osaka area, Kobe, Johnson, Yokota, Nagoya area, Kyoto. It's that there was the large-scale new construction enlargement is more than 50 in there having been enlargement in 8 districts in 12 districts belonging to the 5th Air Force, 5 districts (Nagoya, Tachikawa, Johnson, Itazuke, Itami) of those to understand from the numerical changes from June 1948 to October 1950. Enlargement was not seen in the district that belonged to the 11th AirBorn Division (Sapporo, Hachinohe, Jinmachi), the 1st Cavarly Division (Asaka, Nagai, Ota, Omiya), BCOF (Etajima, Miho, Hofu, Fukuyama), Navy (Totsuka), the 5thA/F (Kisarazu, Chitose, Kanoya) and the 24th Infantry Division (Kumamoto, Beppu). From the number of new construction and rehabilitation and the numerical transformation, it was inferred that the situation peculiar to the occupied area had an influence on the judgment of the requisition and the D.H. construction. Procurement demands of the occupation forces disturbed inflection of building stock of the city space attacked by the war damage. It's the fact that we can't overlook in thinking about after the war of each city. The requisition house rebuilt as a general tendency became the derequisition earlier than new construction. The new D.H. has many examples removed with the return of the requisition, and there are many still uncertain points because there is little number of the existence. In this study, it was clarified that correlation of military unit deployment and D.H. of the occupation forces by the cross-reference of records of the both Japan and the United States. The result of this study will make the base that pushes forward the study on history of city and building in each occupied area.

There were several cases reported where buildings had to stop functioning normally because of the damage to foundations during the 2011 Great East Japan earthquake. The authors carried out static analyses using a foundation structure model in order to investigate the cause of damage to pile foundations by focusing on three typical buildings. Lateral load at pile head and differential movement of soils were estimated based on a seismic response analysis by using recorded ground motions of the 2011 Great East Japan earthquake and by looking into the soil profiles and structural characteristics of buildings. Load-deformation characteristics of pile elements and soil springs were formulated so that the model can incorporate nonlinear behaviors. Results obtained from the analysis explain fairly well the actual damage of pile foundations. It was confirmed that a controlling factor causing damage to pile foundations is the existence of soft soils and the variation of surface soil layers. The proposed procedure can be considered as a practical seismic design method of foundations that ensures a required performance for large earthquakes.

The air quality during winter period in elementary/secondary schools located in metropolitan district X was analyzed by using results of the environmental hygienic audit. The period of analysis was set as 3 years from 2007 to 2009. The following conclusions were obtained; 1) The average values of air temperature, the relative humidity, and CO2 concentration in classrooms of the elementary schools met the standard of school environmental hygiene. 2) The ratio of the CO2 observations exceeding the standard value of 1500 ppm in the elementary schools was 30.5 %, and that in the secondary schools was 58.5 %. 3) The clear tendency that the lower the outdoor temperature, the higher the heating usage ratio, was observed both in the elementary and the secondary schools. Under the same outdoor temperature condition, the heating usage ratio in the secondary schools was higher than that in the elementary schools. 4) Under the same outdoor temperature condition, the average room temperature in the classrooms of the secondary schools was significantly higher than that of the elementary schools. The average CO2 concentrations in the secondary schools exceeded the standard values under the all temperature classes.
