Interpretable Housing for Freedom of the Body: The Next Generation of Flexible Homes

If we have gone through the first generation of housing design that pursued functional optimization, ergonomics, and circulation efficiency during the last century, now we are living in the second generation where more advanced goals, such as universal design, ubiquitous design, sustainable design, and environment-friendly design, are emphasized. Although this second generation of design focuses upon the wellness of humans in accordance with environment, it still has the attitude that a more precisely designed home can guarantee a better life. What lacks in this approach is the freedom of the body; it needs to make its own choice as to how to use a space. Thus, it is suggested in this paper that what is important in designing a home is to provide alternatives in daily lives so as to make a full exploration of a given space. These alternatives can be made by offering residents an interpretable space where they can figure out space usages and routs in a constantly changing context. Two spatial devices are discussed in depths as a way to realize this interpretable house: room-to-room enfilade and ring spatial structure. By investigating some existing house plans, it is illustrated how they can guarantee the freedom of the body, and thus alternatives for the flexible domestic life.

LCA of low-energy flats using the Eco-indicator 99 method: Impact of insulation materials

Sustainable housing is receiving increasing attention by policy makers, architects, consumers and scholars. This study aims at enhancing our knowledge on the environmental impact of sustainable houses by performing a Life Cycle Assessment on a single case study. The case study is performed on a single low-energy building containing 19 flats using the Eco-indicator’99 method.The results indicate that the choice of insulating materials has a significant impact on the eco-score of the design. The materials’ production turns out to be by far the most influential, which bears the consequence that architects and consumers should focus on choosing the best materials in terms of eco-score instead of focusing on an environmental-friendly design. Waste recycling (if possible) has a lower eco-score compared to waste disposal (dumping or burning).

Field Survey on the Indoor Environment of Elementary Schools for Planning of Environment Friendly School Facilities

The purpose of this study is to suggest a direction by which to develop environment-friendly school facilities. To achieve this, field measurements were conducted to evaluate indoor environmental conditions such as thermal, visual and indoor air quality in 15 schools. Additionally, environmental elements were also investigated and analyzed through teachers' questionnaires. According to the results of measurements, the thermal condition, minimum illuminance, CO, TBC and formaldehyde were satisfactory in most of the classrooms. However, CO2, PM10 and TVOCs exceeded the standards. As it was found that the indoor classroom environment significantly influences the academic achievement of students, a plan should be made for indoor noise isolation, comfortable thermal environment maintenance, and uniform light distribution. The environment-friendly architectural design elements applicable to school facilities were found to be: environmental studio, vegetable gardening, school forest, and landscape architecture elements, in this order.

Investigation of the performance of a ventilated wall

The need for environmental friendly and energy efficient building design has stimulated the design of new facade technologies, including various configurations of double skin facades. This paper investigates the thermal performance of a ventilated wall, both for heating and cooling. A thermal analysis was carried out, paying special attention to the characterization of the heat convection resulting from the buoyancy-induced flow in the open air channel which proved to be a critical aspect of the ventilated wall's behaviour. An integrated thermal and air flow model for the entire system was developed. A model of the ventilated wall construction was developed with the ESP-r simulation program and checked against experimental data from a real-scale test cell facility. The thermal benefits of adding a radiant barrier layer were also investigated. The results showed that this layer was beneficial in terms of the energy performance of the construction. Also, the comparison between the experimental and simulation model results showed satisfactory levels of convergence with the exception of the night hours during the summer period. A sensitivity analysis was also undertaken in order to investigate the main factors and the extent of their effect on the temperature variation inside the ventilated facades.

Gas transfer under breaking waves: experiments and an improved vorticity-based model

Abstract. In the present paper a modified vorticity-based model for gas transfer under breaking waves in the absence of significant wind forcing is presented. A theoretically valid and practically applicable mathematical expression is suggested for the assessment of the oxygen transfer coefficient in the area of wave-breaking. The proposed model is based on the theory of surface renewal that expresses the oxygen transfer coefficient as a function of both the wave vorticity and the Reynolds wave number for breaking waves. Experimental data were collected in wave flumes of various scales: a) small-scale experiments were carried out using both a sloping beach and a rubble-mound breakwater in the wave flume of the Laboratory of Harbor Works, NTUA, Greece; b) large-scale experiments were carried out with a sloping beach in the wind-wave flume of Delft Hydraulics, the Netherlands, and with a three-layer rubble mound breakwater in the Schneideberg Wave Flume of the Franzius Institute, University of Hannover, Germany. The experimental data acquired from both the small- and large-scale experiments were in good agreement with the proposed model. Although the apparent transfer coefficients from the large-scale experiments were lower than those determined from the small-scale experiments, the actual oxygen transfer coefficients, as calculated using a discretized form of the transport equation, are in the same order of magnitude for both the small- and large-scale experiments. The validity of the proposed model is compared to experimental results from other researchers. Although the results are encouraging, additional research is needed, to incorporate the influence of bubble mediated gas exchange, before these results are used for an environmental friendly design of harbor works, or for projects involving waste disposal at sea.

434 汎用産業機器の環境配慮型生産・運用技術の開発 : 第 2 報 : 環境配慮型ポンプの設計手法の検討と 3R 情報管理システムの開発

In these years, as the correspondence of the global environmental problems like global warming, exhaustion of energy and so on, the construction of the environmental-friendly society is strongly required. For constructing such society, as concerns the industrial products not only the consideration to 3R (Reduce, Reuse, Recycle) at the design stage, but also the management, by the maker itself, of the energy saving at the using stage and proper treatment for the used products at the recycle and waste stage is demanded under the principle of Extended Producer Responsibility (EPR). However, such a system that manages all the life cycle of the industrial products is not investigated enough. In this study, we attempted to construct such a synthetic environmental-friendly technology for production and operation of industrial machines, especially pump system, by using special IC tag. We call this system, Environmental Information System. In parallel with the development of the special IC tag, which exchanges information between each life cycle stage, we investigate some other technologies for decreasing the environmental impact in each process. Then, in this report, we show the findings of the investigation about environmental-friendly design of pump. We paid attention to the improvement of the disassembling property of the motor, which is one of the most valuable parts of pump, to achieve its reuse and up grading at the using stage. Besides, we got the guide about 3R information management system, which intends to increase efficiency at the disassembling and distinguishing process, which done by hand at present.
