The paper evaluates the environmental advantages and disadvantages of use of aluminium as building construction material for prefabrication of lightweight houses, by examining a case study of the Dymaxion House, designed by R. B. Fuller. The Dymaxion House was conceived as autonomous, transportable, lightweight, and disassembling unit. The predominant material in its envelope is aluminium. The production of this material has significant energy costs and environmental impact. However, aluminium is highly recyclable, long-lasting and has good performance characteristics, which, on the long run, diminishes the pressure on the natural resources and allows a significant reduction of quantity of used material. The paper re-evaluates its environmental impact on a larger time scale and takes into consideration all the aspects of its application. In addition, design strategies, (such as “design for disassembly”) of the house are studied. Finally, paper provides some considerations about the “service industry” system, as conceived by R.B. Fuller (and also used nowadays in enterprises such as Interface Inc.), necessary for securing the house manufacturer's responsibility over the entire life cycle of the dwelling, thus guaranteeing high recycling rates.

The use of batteries of electric vehicles (EVs) for home electricity applications using a bidirectional charger, a process called vehicle-to-home (V2H), is attracting the attention of EV owners as a valuable additional benefit of EVs. To motivate owners to invest in V2H, a quantitative evaluation to compare the performance of EV batteries with that of residential stationary batteries (SBs) is required. In this study, we developed a multi-objective optimization method for the household of EV owners using energy costs including investment and CO2 emissions as indices and compared the performances of V2H and SB. As a case study, a typical detached house in Japan was assumed, and we evaluated the economic and environmental aspects of solar power self-consumption using V2H or SB. The results showed that non-commuting EV owners should invest in V2H if the investment cost of a bidirectional charger is one third of the current cost as compared with inexpensive SB, in 2030. In contrast, our results showed that there were no advantages for commuting EV owners. The results of this study contribute to the rational setting of investment costs to increase the use of V2H by EV owners.

The Impact

The largest of CO2 emissions on earth derives from construction activities. It is necessary to solve the problem to reduce the impact of CO2 emissions. One of the solution to reduce the impact of CO2 emission because of construction activity is using re-used material for building construction, such as re-used shipping container because the re-used material has low embodied energy. This paper has three purposes, and there are: explaining the application of re-used containers as building materials in the context of green architecture, explaining the application of building design using re-used containers as material, and explaining the advantages and disadvantages of used containers as building materials. Creative Hub ITSB as a case study owned by the campus of ITSB. The building construction consists of 20 units of a re-used container (20 feet size). The prefabrication construction uses for each steel material. Each component of the building assembled in the workshop, then it delivered to site by truck. The main issues that need to be solved are a matter of the delivery system, the structure, and joints, and the component assembly. Cross-ventilation system and insulating material also crucial because it can reduce building temperature.

Modular floating pontoon is a floating device commonly used as civil and marine construction. Pontoon is usually made of steel and high-density polyethylene (HDPE). Although the steel and HDPE has its own advantages and disadvantages in terms of economic, strength, and capacity. However the study of alternative raw materials for modular floating pontoon construction as multipurpose floating equipment is needed. Ferrocement which is familiar in the used for building construction material is an alternative material. Since the material is easy to find and it is such a versatile material that can be mass produced and has the mechanical strength that is simillar to steel and other materials. Following that condition the research is focused on the application of ferrocement technology for modular floating floating pontoon. The results show that the principal dimension of modular floating pontoon are length 80 cm, width 80 cm, height 75 cm, with the lightweight draft of pontoons is 30 cm. The material proportions for the modular floating pontoon are sand 48.2%, cement 34.5% and water 17.3%. Modular floating pontoon series consists of four Pontoons Square compiled with interlink (hook) so that the total of the package pontoon has a 160 cm long, 160 cm wide and 75 cm high.

Design Result

BACKGROUND most serious games and other game-based tools are designed as digital games or escape games. They are designed for learning or sometimes in the field of medicine as an aid to care. However, they can also be seen as an aid to research, in our case, to evaluate the advantages and disadvantages of imaging techniques for cancer detection. OBJECTIVE we present a case study of action research on the design of a serious board game intended to consider the advantages and weaknesses of a diagnostic method in a different ways. The goal was to better understand the principles of designing a tool using game or play. METHODS we explicitly implemented another process than gamification to develop a structure reminiscent of the game to highlight the strengths and weaknesses of different imaging techniques from the point of view of the respondents (in this case specialists not directly involved in the project). Based on this feedback and the scientific literature on this subject, we detail the main categories of games and games developed for serious use in order to understand their differences. Concerning the cancer research part to which game contributes, our method is based on questions asked to experts and practitioners of this specialty. RESULTS an expert point of view translation tool in the form of a game has been realized to apprehend a research in a different way. CONCLUSIONS we show with the help of a diagram, some possible design paths leading to this type of design result including two hidden dimensions to consider (the awareness of the game or play by the "player" and his role as a contributor or recipient).
