  • This study aims to evaluate the optimal size of the hydrogen facility to be installed in a zero-energy district in terms of load matching and facility efficiency. A mismatch between energy generation and consumption is a common occurrence in zero-energy districts. This mismatch adversely effects the energy grid. However, using an energy carrier such as hydrogen can solve this problem. To determine the optimal size of hydrogen fuel cells to be used on-site, simulation of hydrogen installation is required at both district-and building- levels. Each case had four operating schedules. Therefore, we evaluated eight scenarios in terms of load matching, heat loss, and facility operational efficiency. The results indicate that district-level installation of hydrogen facilities enables more efficient energy use. Additionally, based on the proposed model, we can calculate the optimal size of the hydrogen facility.

  • In order to set the direction of providing facility for the utilization of castle heritage, as well as to establish the method for securing access and determine installation criteria in consideration of preservation environment, an analysis was carried out on the cases of having secured access for people with disabilities in England for the advanced utilization of castle heritage. As the result of the analysis, the planning factors of the facility for people with disabilities in England for the utilization of castle heritage were deduced as follows: 1) The plan for facility was focused on the disabled using wheelchairs and visually impaired persons, rather than on services for hearing-impaired persons and people with learning disability. 2) As for audience movement line plan, regular route was used for audience movement line to lead them in a single direction. 3) As for the provision of prior access information, 3 stepwise access grades were established for the facility information plan of heritage. 4) As for information service by disability type, models were provided; and complementary explanation was provided by using text, drawing, picture, video and voice. 5) Rest spaces were secured where audience could look out upon castle heritage. For the utilization of castle heritage, it is necessary to develop planning factors of the facility design for people with disabilities according to its characteristics.

  • Facility layout problems (FLP) are usually treated as design problems. Lack of systematic and objective tools to compare design alternatives results in decision-making to be dominated by the experiences or preferences of designers or managers. To increase objectivity and effectiveness of decision-making in facility layout selections, a decision support model is necessary. We proposed a decision model, which regards the FLP as a multi-attribute decision making (MADM) problem. We identify sets of attributes crucial to layout selections, quantitative indices for attributes, and methods of ranking alternatives. For a requested facility layout design, many alternatives could be developed. The enormous alternatives, various attributes, and comparison of assigned qualitative values to each attribute, form a complicated decision problem. To treat facility layout selection problems as a MADM problem, we used the linear assignment method to rank before selecting those high ranks as candidates. We modelled the application of the Nemawashi process to simulate the group decision-making procedure and help efficiently achieve agreement. The electronics manufacturing service (EMS) industry has frequent and costly facility layout modifications. Our models are helpful to them. We use an electronics manufacturing service company to illustrate the decision-making process of our models.

  • A radiotracer investigation was carried out in a Thermal Stratification Test Facility (TSTF) with objectives of investigating the dispersion and diffusion of radionuclide and effectiveness of the thermocline to minimize the radionuclide content in the hot water layer. Technetium-99m (99mTc) as sodium pertechnetate was used as a radiotracer in the investigation. Qualitative analysis showed that a thermocline is formed within the TSTF and is effective in preventing the transport of radionuclide from bottom section to the top section of the facility. It was found that the radiotracer injected at the bottom of the pool took about 17.4 h to disperse from bottom to the top of the facility. The results of the investigation helped in understanding the effectiveness of hot water layer and thus to minimize the pool top radiation levels.

  • This study proposes an improved genetic algorithm (GA) to derive solutions for facility layout problems having inner walls and passages. The proposed algorithm models the layout of facilities on a flour-segmented chromosome. Improved solutions are produced by employing genetic operations known as selection, crossover, inversion, mutation, and refinement of these genes for successive generations. All relationships between the facilities and passages are represented as an adjacency graph. The shortest path and distance between two facilities are calculated using Dijkstra's algorithm of graph theory. Comparative testing shows that the proposed algorithm performs better than other existing algorithm for the optimal facility layout design. Finally, the proposed algorithm is applied to ship compartment layout problems with the computational results compared to an actual ship compartment layout.

  • The purpose of this study is to identify the elderly housing farcility design preference by comparing two groups, the present residents living in elderly housing facility and the middle aged. The latter has more housing experiences and more design oriented standard of selecting house for quality of living, while the aged are oriented more in economy and investment. It is identified that both group preferred living in elderly housing facility best to any other elderly housing type, including "aging in place." The aged are not yet very concerned about physically homelike design features, but when the middle aged need the elderly housing, it is recommended that more variety and amenity in its type, location, plan and design features. The idealistic facility planning and management system were suggested.

  • This study was executed by means of "user participatory design method", as a part of the public facility remodelling project supervised by the Seoul Municipality. This study aimed to complement and improve the methodology through reviewing the whole process of participatory design implementation and examining closely whether the activities, design methods and tools that have been applied at each stage were helpful to reflect the users' demands successfully. Given all of those, it implies; first, it is very meaningful that public facility remodelling project by "user participatory design" leads the ordinary users to have direct opportunity to participate in the public business and to change their perception of the restroom environment in school. Second, it is necessary to integrate the roles of the facilitator and the architect from the beginning stage of the process, which makes it feasible to reflect the users' needs to the final stage. Third, it is required to modify the design tools that enable non-professional participants to understand their tasks and to perform them effectively at the stage of decision making.

  • This study aimed to suggest a 1300 scale of a middle school foodservice facility floor plan which was compliant to the principle of HACCP, as well as ensuring food and work safety, and the flow of personnel and food materials. which consisted of 46 nutrition teachers and 6 experts, responded with a questionnaire on the relationship of functional area and space. Using their opinions, key principles for the design of the facility were single direction movement of food materials, customers and workers; minimization of the cross-contamination through the separation of functional space; and securement of customer-focused efficiency; staff-centered convenience and efficiency; and work and food safety. After the completion of an adjacency diagram, bubble diagram and program statement, the functional areas of a 1300 scale middle school food-service facility were allocated as follows: $9.9\;m^2$ for the receiving area, $56.1\;m^2$ for the pre-preparation area, $10.5\;m^2$ for the food storage area, $6.0\;m^2$ for the supplies storage area, $97.8\;m^2$ for the cooking area, $33.6\;m^2$ for the service area, $52.5\;m^2$ for dish washing area, cafeteria $410.5\;m^2$, $4.5\;m^2$ for the front room, for a total of $725.8\;m^2$. Expert groups have pointed to limitations within this model as there are no windows in the office for the influx of fresh outside air and a need for the straight line installation of steam-jacket and frying kettles on the sides of windows. This study can be useful as the guidelines for estimating the investment cost of the facility and placing the placement of functional areas and equipment in the renovation of the facility. It can be also useful data for a methodology of foodservice facility design.
