This paper has examined and made formal analysis of the sketches included in the 5th chapter of “Alpine Architektur”, especially the sketch titled “Grottenstern”, by Bruno Taut, and has clarified that its ornamental forms were composed of the historical forms, vegetable forms and crystal forms which are collected and unified into an utopian figure. It is also found how the cosmic ideas of an expressionistic novelist Paul Scheerbart were put into concrete forms and various formal elements and the expressionistic construction were generated by Bruno Taut.

When the concentration of an aerial pollutant is detected at some observation points in an urban or built environment, immediate source identification allows for application of effective measures to decrease the concentration of the pollutant and its adverse effects. In this case, source identification involves determination of the source position and source strength from measured concentrations. We propose a novel method for identifying the source of an environmental pollutant continuously released from a point source in a turbulent flow field at a statistically steady state. The method employs the analysis of tracer dispersion released from observation points of the pollutant in a reversed flow field (RFF). The RFF is artificially produced from the forward flow field (FFF) in which the pollutant is transported. The direction of temporal progress and velocity vectors in the RFF are created opposite to those in the FFF. In a statistically steady turbulent flow and concentration field, the concentration of matter at a position can be expressed as a product of its source strength and expected staying time (EST) per unit volume at the position of a particle of the matter. From the discussion on the probabilistic behavior of a virtual particle in the flow fields, we found that the EST between two related points has an identical value when the release and monitoring points are interchanged in the FFF and RFF. Using the relationship of the EST and the tracer dispersion from the observation points in the RFF, the measured concentration of the pollutant and the EST give the estimated source strength as a function of the position. This property coincides with the duality of the scalar fields analytically derived in the adjoint method. When they have multiple observation points, each tracer dispersion analysis gives different distributions of the estimated source strength. However, the source strength has to have a unique point value for physical realizability. This condition reduces candidate positions of the pollutant source. When the dispersion of the pollutant occurs in the n-th dimensional space, the number of parameters is n + 1, which contains n space coordinates of the source position and the source strength. Consequently, n + one observation points allow the determination of all parameters in the source identification. This paper presents the basic idea of the source identification method based on physical consideration of the particle behavior in the RFF. An example of the source identification procedure is also presented for pollutant dispersion in a two-dimensional uniform flow field. However, the solution of source identification obtained with the present method can be very sensitive to the errors that are assumed to occur in the measurement or analysis of flow and concentration fields. For practical applications, an additional method to provide robust solutions against these errors are needed and will be considered in future studies.

This study analyzes the pedestrian's avoidance behavior in crossing flow in order to obtain quantitative criteria for evaluating the difficulty of walking in a crowd. The new graphic illustration methods, called Short-Time Pedestrian Path Diagram and Direction Rose Diagram, are developed and proposed in this paper to represent the state of a crowd visually. The result of our experiment suggests that pedestrians descend their walking speed or/and detour to avoid striking other people and each avoidance behavior can be classified into three levels, whose threshold are defined from the speed or the angular velocity of each pedestrian.

This study aims to clarify the mechanism of the appeal in shopping streets by the distinctive characteristics of the boundary design of the shop and the street, for example, the facade of the shop, signboards, overflow, the type of shop, setback distance, frontage width, pedestrian's line of flow, and the traffic form of the street. We performed physical space characteristic analysis and psychological evaluation analysis by the Semantic Differential method in Nishijin Area. The results are as follows: l.The facade is closely related to overflow, the type of shop, the flowline, the traffic form. 2.The space composition of the street is characterized by the facades. 3.In evaluation of the street, psychological evaluation of "prosperity" and "tastes" is not in complete agreement. 4.Various psychological evaluations are affected in the street by many shops with Open-facade.

Energy conservation technology has been in high demand in relation to efforts to realize (net) zero-energy buildings (ZEBs). Ceiling radiant cooling panel systems represent a key energy-conservation technology which can yield high efficiency, since it uses moderately cold water (1618°C), offers integration with other energy-efficient strategies, such as indirect evaporative cooling or ground source heat pumps, and does not require energy to propel a fan to remove the cooling load. Furthermore, a radiant ceiling cooling panel system provides greater comfort to occupants because it does not produce a draught. Therefore, ceiling radiant cooling panel systems can offer both reductions in cooling energy consumption and a comfortable environment for occupants. However, there are several problems with applying a ceiling radiant cooling system in Japan. Firstly, there is limited data about the cooling performance of such systems because few have been constructed in Japan. For this reason, it is important to determine the cooling performance of radiant ceiling panels. Secondly, radiant ceiling panels have limited cooling performance, so it is necessary to consider a special system to remove the perimeter load. Thirdly, an outdoor air-conditioning system is needed to provide outdoor air to occupants. The objective of this paper is to present an outline of the proposed system, results of the thermal performance tests in an experimental facility, and the operational performance in a building to which the proposed system is applied. The proposed system consists of ceiling radiant cooling panels, perimeter chilled beams, and an outdoor-air supply system. The ceiling radiant cooling panels remove the interior cooling load. The perimeter chilled beams remove the perimeter cooling load. The outdoor-air supply system has a personal floor diffuser, a perimeter linear diffuser and a return-air inlet near the window top. The return-air inlet removes the hot air from the window to remove the perimeter load efficiently. An experimental facility for the proposed system was constructed, and thermal performance tests were performed. The results show a vertical temperature differential of less than 0.5°C, and the perimeter chilled beam can remove the peak summer cooling load appropriately. The cooling capacity of the ceiling radiant cooling panels and perimeter chilled beams are approximately 80 W/m2 and 120 W/m2 respectively under conditions whereby the difference in temperature between the water input and output is 9.0°C. Measurement of the system was performed in the actual building to which the system was applied. The results show that the ceiling radiant cooling panels and chilled beams can be controlled to remove varying cooling loads. The cooling capacity of the ceiling radiant cooling panels and chilled beams in the actual building proved almost equal to the experimental data. Thus, it is demonstrated that the proposed system can remove the cooling load as expected.

The attentive action of pedestrians turning their heads toward shops on a pedestrian mall was observed and its characteristics were analyzed in this study. It was found that the attentive action during both daytime and nighttime became more frequent, the larger the opened parts like a entrance and window of the shop in terms of shops, and smaller the scale of the shop in terms effacing distance to the mall. It was also found that pedestrians tended to show more attentive action at night than day. It has become evident that attentive action becomes more frequent when the light from inside a shop leaks outside strongly.

Recently, applications of CFD (Computational Fluid Dynamics) are expanding to various environmental issues such as pollutant/thermal dispersion in urban areas. The outdoor environment sub-committee of the Architectural Institute of Japan have conducted several benchmark tests for obtaining basic information and knowledge in order to provide the extended practical guidelines of CFD, which can be applied to more broad environmental issues than the present ones. This paper reports the results which considered the sensitivity of various computational conditions in the RANS (Reynolds-Averaged Navier-Stokes equations) model to the prediction accuracy of pollutant concentration distributions for two different configurations.

This paper aims to clarify the spatial problems of a place for immigrants by analyzing a group of small shops built by immigrants in A housing complex. A residents' association established the land, which was built the shops. They had a role as a node for ethnic groups. But they were removed because the segregation had occurred. By analyzing their transition, following problems are found: 1. Locating to the outside of the living region. 2. The construction urged by the spatial form of enclosed land. 3. Lack of communication with the local residents. 4. Spatial closure of the shops.

Energy consumption survey is conducted in a university campus with co-generation system used for 22 years. According to the hourly data in a complete year, the performance of the whole system including the electricity generation, waste heat recovery, and gas consumption, the operating conditions and the overall energy efficiency is analyzed. The overall energy efficiency reaches 43% to 69%, which shows this energy system still maintains good performance. Then it is pointed out that the correlation coefficient between the energy consumption for cooling and the natural logarithm of outside air temperature exceeds 0.9 in this article. And the load curves for multi-unit control are also illustrated, which can be used to evaluate the performance of the whole system. Furthermore, the authors propose the optimization of the number of operating gas turbines, which improves 2% the overall energy efficiency in summer.

Ordinance-designated cities have been decreasing the population, causing a hollowing out of urban centers. The number of schoolchildren there has dropped dramatically. As the result, merging and closing down elementary schools is prevailing and the dealing of the old schoolhouses and schoolyards becomes a big community-issue. Generally ordinance-designated cities decide the way of reusing such school-properties by administrative initiative, but Kyoto City takes the way of citizen's participation to decide it(The Kyoto Method). In Kyoto its community organization (Machigumi) and an elementary school have nurtured a strong relationship historically from the Meiji Era to today. This relationship becomes a kind of community culture and grows into a community resource. The Kyoto Method is the product of this unique relationship between Machigumi ando an elementary school, and realizes community-oriented reuse of old school-properties.

The seismic isolation retrofit of the main building of the National Museum of Western Art required excavating the foundation ground under the existent building and installing isolation devices beneath the existing footings. Before the installation of isolation devices, it was necessary to construct piles beneath the existing footings in order to support the weight of the building temporarily during excavation process. The piles were made of steel pipe segments, and were driven by oil jacks utilizing the weight of the building for reaction force. During the retrofitting process, the subsidence of the building supported by the piles were monitored and controlled to avoid causing damage to the superstructure.

This Paper discusses the possibilities and contributions of establishing 'design-oriented components', which provide flexible design for the A/E, and concludes follows. 1. The production system of component manufacturers has enough flexibility to accept special orders from the A/E since they have changed from production for stock to that for order. 2. There is no reason why the A/E selects ready-made components only for his design, nevertheless the idea of open system has been based on such components manufactured by the production system for stock. 3. It is essential to establish design-oriented components with which their information is represented by a means of operating their attribute easily. Such components are expected to gather A/E's needs for new developments by component manufactures.
