Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 3~10
DOI : 10.5659/JAIK_PD.2014.30.7.3
In response to the increasing severity of environmental pollution, the energy-efficient designs that minimize carbon emissions have been increasingly discussed. After the increasing adoption of Building Information Modeling(BIM), various domestic and international attempts for BIM-based energy performance assessments have been investigated, but most of them have generated various problems from the lack of data interoperability. It makes users inefficient with inputting again the building information which are not compatible at energy analysis phase. Also through energy analysis, the feed-back of results can not be applied bidirectionally for back to the early modeling phase. The purpose of this study is to suggest improvement of interoperability for open BIM-based building energy assessment through object library system. To achieve this purpose, the authors have constructed the object material library based on ASHRAE Handbook reflected domestic material classification system and developed module for pre-checking and modification of material information in energy performance assessment. This study could reduce confusions from different processes and environments and offer the confidence to user. Furthermore as the alternative to lack of data interoperability, the object material library applied domestic state and ASHRAE Handbook can be reliable.

There are 11,080 primary, middle and high schools throughout the nation including approximately 30,000 facilities. 49% of them have been worn out over 20 years and become increasingly deteriorated. For maintenance of school facilities, regular safety checks have been conducted under control of relevant departments of regional Education Office. However, as maintenance cost increases due to damages of abrupt climate change, no additional budget has been arranged. In addition, school facilities which has been performed under 8-year Build-Transfer-Lease projects conducted Life Cycle Cost analysis in planning and design stage and 25-year prospective maintenance fee was estimated. However, it could not reflect climate or energy consumption environments changes. To solve these problems, affecting variables on climate and energy consumption environment changes which might affect LCC analysis and maintenance were drawn. For major factors, climate change variables were temperature, precipitation, humidity, natural disaster, etc. Energy consumption environment variables were school grade, source of energy, work type, room, class size, etc. Targeting experts and hands-on workers, multi-criteria decision making method was applied to analyze propriety of climate and energy consumption environment affecting variables and level of impact of them on work type. Results of this study as Variables affecting climate and energy consuming environment change, weights, and the level of impact on work type can be applied as compensation coefficients for school facility LCC analysis results.

Lee, Do-Young ; Chung, Hyun-Mi ;
Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 41~52
DOI : 10.5659/JAIK_PD.2014.30.7.41
This study proposes to develop an integrated class operational model for training architecture-based professionals of public design on an undergraduate level, and then apply it to a
year design studio course of 'A' university held in Fall semester 2013. Basically, it is assumed that two different levels of integration occur simultaneously in the study. One is related to integration by academic realms that are representative of architecture and public design, while the other is integration by types of thinking to be inclusively developed in class via the design education process. In order to scrutinize the first level of integration, a conceptual framework developed in 2013 for architecture-based public design education was used. The second level of integration, additionally, is related to a test if an ability of both problem understanding and solving necessary for architecture-based public designers can be improved by integrating a variety of types of thinking used practically in the on-going design process. Based on understanding of Bloom's 6 stages of extended thinking process(recognize, understand, apply, analyze, synthesize, evaluate), a 6 set of problems were developed and used for task performance. Three teams composing of 4 students for each were asked to solve their problems in the revised Bloom's 5 consecutive thinking process; (1)presentation of personal solutions resulted from team activities, (2)critique or analysis of each individual member's work in a team, (3)preparation of a synthesized best alternative based on the critique or analysis, (4)evaluation on the overall working process at a team level, (5)preparation and submission of final output sheets. Each problem was supported by relevant guiding questions to help teams to work out in a right and effective direction. Results of the study show that an integrated approach of this sort to raising architecture-based public designers is likely to have a highly positive effect on increasing the possibility.
A Study about Transformation of Shopping mall
Baek, Young-Won ;
Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 53~61
DOI : 10.5659/JAIK_PD.2014.30.7.53
This study was conducted to clarify the cause of another transformation of the mall, as its transformation not only requires movement (rambling) or encounters of people, but it also requires various intelligent manipulations, and pursues space layout for amenity. In other words, the process of transformation of the mall involves transformation from a space that avoids encounters with social members and ritualizes movement (rambling), into the space of rambling (movement) that encourages encounters with different social members, and the purchase of goods while taking a walk. The second step of the transformation requires various intelligent manipulations, and creates amenity. Also, this process of transformation is interpreted using the concept of Romedi Passini's Wayfinding Theory, Amos Rapoport's Space Transformation Theory, Christian Norberg-Schulz's Setting-into-work, and the Semiosis of C.S. Peirce or C. Morris. ie. This particular study aims to examine the flow and causes of transformation in shopping malls following the foregoing discussions, applying the concept of 'true character of things' put forward by Karl Popper. Based on these series of discussions, this study examines the symbolic value of commercial buildings along with postmodernism from a completely different perspective.

Ju, Yeong-Gyeong ; Seo, Youn-Kyu ; Hong, Won-Hwa ;
Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 63~70
DOI : 10.5659/JAIK_PD.2014.30.7.63
The purpose of the study is to analyze the energy saving effect according to the remote energy management system in the electric grid of the micro energy grid. Micro energy gird which includes electric grid, gas grid, heat grid and off grid is a grid that aims energy self-sufficiency at a small unit. To notify the energy saving effect applied to the electric grid among the micro energy grid, control the energy consumption for each building, manage the electricity through the energy operation center and analyze the effectiveness of the MEG. The total energy consumption would be demonstrated through the monthly and daily data and the energy saving would be verified as analyzing the hourly data in the MEG. The result of the remote energy management, MEG shows average of 10% on energy reduction and it is proved that the MEG is effective in energy saving. This study can be offered as the basic data for optimal energy management through the energy consumption pattern applied in Korea-micro energy grid.
Analogizing mutual relation with Pilot House B-type in Seoul and Reclamation House in Jeju Island named Ctesiphon
Park, Cheol-Soo ;
Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 71~80
DOI : 10.5659/JAIK_PD.2014.30.7.71
This paper investigated the relationship between the B-type pilot house (the Isidore house) by the Korea Housing Corporation in 1963 and the Ctesiphon house that was built as reclamation houses in 1961 and 1962. Both types of houses were built based on the Ctesiphon system for design, construction, and material, which was developed by an Irish engineer and inventor named James Hardress de Warenne Waller, which lead researcher to develop following conclusions: First, the reason for calling the B-type pilot house as Samahn-type was that the company for construction was Samahn Industry. The recording of Sung, Ik-Hwan and Ye, Gwan-Su as designers should be corrected because Ye, Gwan-Su was a retired colonel who founded and managed the company. Second, researchers confirmed that both the Ctesiphon reclamation house of the Jeju Isidore housing by the priest Patrick James McGlinchey and the B-type pilot house of Suyu-dong are built based on the Ctesiphon system for structure, material and construction. Third, the Ctesiphon system, which was widely used in Europe from 1940s, was applied to the Jeju Isidore housing by the priest McGlichey. Then, the Korea Housing Corporation used the system as a reference. This corresponds with the timing of construction and the fact that the B-type pilot house is often called as the Isidore type or the Isidore house.

Choi, Jaepil ; Lee, Jung-Won ;
Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 81~90
DOI : 10.5659/JAIK_PD.2014.30.7.81
This study has been proceeded based on the idea to develop an expert system for vertical transportation planning in high-rise buildings. Housings and hotels, which are two of the main usages in high-rise buildings, were researched. Components of the system, which are 'database', 'explanation facilities', 'inference engine', and 'knowledge base', were actualized based on information about vertical transportation planning for the studied usages. These contents were materialized to construct an algorithm which can be used for planning high-rise housings and hotels based on simple building information. Through further research, an expert system can be developed to support evaluating and selecting design alternatives economically and efficiently in the process of designing high-rise buildings.

DOI : 10.5659/JAIK_PD.2014.30.7.91
This paper aims to analyze NAHP(National Affordable Housing Programme), UK focusing on the relationship between its supply process and Design and Quality Standards(D&QS) in view of the quality of housing environment. NAHP has five steps which are pre-qualification, bid, assessment, selection of plan, and review of implementation. D&QS is adapted to the steps of assessment and review of housing environment after completion. The contents of D&QS are compared with the standards of Korea on the basis of the framework including safety, convenience, comfort and sustainability. As a result, the standards of Korea get score more than UK in the aspects of safety, convenience and D&QS of NAHP get more score in the aspects of comfort, sustainability. Furthermore the former has more the standards of physical facilities for residence while the latter has more the standards of plot and regionality which are helpful for the adaptability of different housing types.

A Study on the Bulguksa Dabot'ap expressed in the symbolism of Ŭisang's ilsŭng pŏpkyedo and Muyoungt'ap
Kwon, Hwang-Su ;
Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 111~122
DOI : 10.5659/JAIK_PD.2014.30.7.111
Bulguksa Dabot'ap was not built symbolize of the Many-treasured Buddha's anytime prove but built symbolizes of the Sakyamuni Buddha's anytime sermons and his preaching four place in the sky of the Avatamska Sutra that represent muyoungt'ap is meant to Sakyamuni Buddha's Mah
ya preached equality to the light illuminates without shadows. And, the pagoda's overall appearance of the visualization and manufacture of stone blocks by the grid was also master
pkyedo(Diagram of the Avatamsaka One Vehicle Dharmadh
tu). Looking at each floor of the symbolism, the first floor is symbolize the ils
pkye of Hwa
m doctrine and second-fourth each floors represents three world of the Buddhists law. Other, the each floors of the symbolizes Bodhisattva(self-discipline) vehicle and each floor plans of the symbolizes Dharmacakra shape. So, the pagoda is to be based on the symbolize of master
pkyedo and his Hwa
m philosophy or Hwa
m doctrine. This pogada is the symbol of largely due to
isang's efforts, Hwa
m philosophy came to dominate the mid-eighth century Silla Buddhist scholasticism.

Ancient Buddhist temples in China began to be built in the
century, and numerous temples were built during the Six Dynasties period (420-589 AD). The site layouts of only about five temples built between the late
centuries have been identified through excavation. These temple sites have a single pagoda/image hall style and reveal a process of change over this 100-year period. This paper describes in detail how these five temple sites, despite having the same single pagoda/image hall form, show differences and changes. The underlying reasons for and significance of this process of change are also investigated. These sites demonstrate well the process by which temple layouts changed from a pagoda-centered arrangement to an image hall-centered arrangement. This development is closely connected to Korean Buddhist architectural plans during the same period.

Song, Jong-Eun ; Park, Yong-Seo ;
Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 133~144
DOI : 10.5659/JAIK_PD.2014.30.7.133
Both sociologists, Ronald W. Smith and Valerie Bugni have examined application of Symbolic Interactionism of a sociological theory into architectural design thinking method. The paper explores following issues from their serial publications including seven essays from AIA Las Vegas Forum Newsletters, two papers of sociological journals, the first chapter of a forthcoming book, and a syllabus naming "Architectural Sociology": 1)How do they derive culture, social interaction, and self as frameworks for sociological studies of architecture from Symbolic Interactionism to apply architectural design thinking methods, 2)What is the implication of architectural decoding of Holocaust Museum of Washington D.C. in terms of Symbolic Interactionism, and 3)How do they apply these concepts to the design of World Trade Center Memorial in New York. The paper concludes with describing limitations of their frameworks and potentials of Symbolic Interactionism as a architectural design thinking method.
A Study on the Building Layout of Gowon Area in the Site of Buddhist Temple Hoeamsa
Han, Ji-Man ;
Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 145~155
DOI : 10.5659/JAIK_PD.2014.30.7.145
The purpose of this study is to clarify the building layout of Gowon(庫院) area in Hoeamsa Buddhist temple which rebuilded by Zen priest Naong(懶翁) in the late time of Goryo dynasty, by comparison analysis of excavated ruins, Cheonbosan-hoeamsa-sujogi(天寶山檜巖寺修造記), and Zen Buddhism temple of China and Japan in 13-14 century. The Gowon was the core facility to conduct the management of Zen Buddhism temple. The Gowon area of Hoeamsa site is located on the east side of 3, 4 sectors, which are in the south direction of main Buddha hall. The elements of Gowon of Hoeamsa in late time of Goryo are kitchen, dormitory for Jisa(知事), Witajeon(韋陀殿), attached storage, and so on. These elements are very similar to the Zen Buddhism temple of China and Japan. It means the influence of Chinese Zen Buddhism temple introduced by Naong. But from the view point of the location in the temple, the Gowon of Hoeamsa was different from that of China, which was located on the east side of the main Buddha hall, and made symmetry with Seungdand(僧堂) on the west side of the Buddha hall. And some misdescription was found from the Cheonbosan-hoeamsa-sujogi on the name, bay composition and location of some buildings.
A Study on the Advent of Sasang Dogo and the Construction of Hwasung in the Late Joseon Dynasty
Kim, Byeong-Ju ;
Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 157~165
DOI : 10.5659/JAIK_PD.2014.30.7.157
The purpose of this paper is to explain the correlation between construction of Hwasung city and commercial world in the late Joseon dynasty. In 18th century, the leading part of commercial world was changed from Sijeon(licensed shops; 市廛) to Sasang Dogo (private merchant; 私商都庫). Sasang Dogo got the command a place of great commercial importance, and they bought up goods that come up from provinces to capital Hanyang. The government had a sense of crisis about this private merchant system of the commodity circulation. As a result, the government built the new city Hwasung at important position of traffic, and then did to pierce the arterial road Samnamdaero in Hwasung city. This paper revealed the change of city location's concept in Joseon dynasty of 18th century.
A Development of the CO
Emission Estimation Model Based on Urban Form
Kim, Min-Ha ; Kim, Young-Ook ;
Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 167~173
DOI : 10.5659/JAIK_PD.2014.30.7.167
This paper proposes, in the context of low-carbon urban form, a GIS-based quantitative model to estimate carbon emission amount primarily affected by the spatial configuration of street layouts and building masses. This microscopic model is composed of the two parts: carbon emission directly caused by horizontal vehicular movements between buildings and that which is transformed from electricity consumption by vertical elevator movements within buildings. The performativity of the model is then examined through the simulation with New Town Projects in Seoul, with a special attention to their local height and grid intensification conditions. Taking carbon emission amount as a single currency, we aim through this study to idenfify the structural effects of urban form on carbon emission thus to make comparative morphological studies possible in our continuing efforts to reduce the amount of carbon emission in cities.
A Research on the Methodology for Mating the Spatial Structure and the Usage of a Certain Urban Area
Lee, Sang-Hyun ; Chi, Cheng-Yun ;
Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 175~183
DOI : 10.5659/JAIK_PD.2014.30.7.175
The aim of this research is to provide a systematic methodology for mating the spatial structure and the usage of a certain urban area. Generally speaking, the commercial use is allocated to the area which is easily accessible while the residential use is allocated to the area which is relatively less accessible. However, there are a lot of situations in which such a general rule does not work and in that situation, such an area does not work properly. To resolve this problem, it is required to make some changes in the spatial structure and/or the usage of a certain urban area. Both strategies would be good solutions for fixing the problem, but the latter one is not practical. Therefore, the former one could be more efficient and practical solution. The aim of this research is achieved by suggesting an index for representing the spatial structure such as "Integration Average" of a certain urban area; providing a means for changing the urban spatial structure through creating the new roads and deleting the existing roads; dealing with finding the very roads which can make the biggest changes in the index, "Integration Average" as above.
Analyzing the Impacts of Business Supporting Services of Technoparks on User Satisfaction
Song, Ho-Chang ; Park, Hak-Mok ;
Journal of the architectural institute of Korea planning & design, volume 30, issue 7, 2014, Pages 185~194
DOI : 10.5659/JAIK_PD.2014.30.7.185
The following thesis focuses on the efficient operation and maintenance of Technoparks' corporate support system. Therefore, the influence reflecting the supported corporations'satisfaction was analyzed. The Partial Least Square-Structural Equation Model (PLS-SEM) was used for the analysis of supported corporations'satisfaction. the result of supported corporations' performance and satisfaction analysis showed that research development support and network support were influential factors for the total satisfaction of supported corporations. The perspectives taken for this study are the following. First, if the satisfaction for support service, labor support service, technical skill service, knowledge support service and marketing support service are increased, then the corporations' performance and innovation increases as well. However, in the case of research development service (research development's investment and support, commercialization support), the satisfaction level is higher and influences the corporations' performance and innovation. Secondly, the corporations' total satisfaction not only reflects the types of service, but on quality of service and processing speed of service as well.

This research is an experimental study of the liquid desiccant system performance. In the absorber, dehumidification process and sensible cooling of outdoor air takes place at the same time. The dehumidification effectiveness variation with the chilled water temperature changes in the absorber based on the experiment data collected from the liquid desiccant system operation. The liquid desiccant system used in this research dehumidifies
process air and 24.5kW air-cooled chiller or 136.1kW cooling tower may provide chilled water at target temperature. Experiments were conducted on the day of peak cooling load of outdoor air in the summer season when the outdoor air was hot and humid(at Incheon, South Korea. Aug 2013). Based on the experiment data showing the dehumidification performance variation of the liquid desiccant system for the cooling water temperature, a validation of the dehumidification effectiveness values of a liquid desiccant system is compared with existing model.

Active chilled beam systems, which have been gaining much popularity recently in Europe and North America, are known to be not only energy-efficient but also advantageous to uniform indoor environment quality. The objective of this study is to evaluate the performance of an active chilled beam system, in terms of air diffusion and local discomfort in the conditioned room. To do this, the evaluation was conducted using a full-scale test bed, where an active chilled beam system is designed and operated with a dedicated outdoor air system. A 2-axis traverse system was utilized to measure the air temperature and air velocity in the entire space of the test bed. The performance was evaluated using the three indices: ADPI to evaluate the uniform thermal comfort, DR(draught rate) to evaluate the discomfort due to excessive air movement, and vertical air temperature difference to evaluate local discomfort due to thermal stratification. The result shows that active chilled beam system is successful in providing the uniform indoor thermal environment with less supply air flow rate.

For Model-Predictive Control (MPC) to be implemented in real application, data driven inverse models are advantageous since they are easily constructed as well as relatively fast and accurate, compared to first principle based models (simplified calculation [ISO 13790], dynamic simulation [EnergyPlus, ESP-r, TRNSYS, etc.], state space models, etc.). Gaussian Process Model (GPM), one of the inverse methods, can be beneficially used for real time stochastic optimal control of nonlinear building systems, since the GPM consumes much less computational time and does not require significant efforts. The GPM is a black-box model based on Bayesian approach based on measured in-output dataset. For real-time optimal control of chiller operation, this paper presents a coupling between the GPM and an optimization routine in MATLAB optimization toolbox. The two control parameters studied in the paper are the outlet temperatures of chilled water loop and cooling tower loop. In particular, Genetic Algorithm (GA), one of the meta-heuristic methods, was applied to find optimal control strategy. It is elaborated in the paper that GPM produces reliable control results reflecting probabilistic natures of the chiller system.

Due to increasing problem of depletion of traditional fossil fuel such as coal and petroleum alongside of effort to contral Carbon Dioxide gas emission, need of alternative energy becomes top priority. Amongst many alternative energy solutions, Piezoelectric energy harvesting system, transforming wasted kinetic energy such as pressure and vibration to electronic energy, became top research. Unfortunately, only research regarding battery efficiency in Piezoelectric energy harvesting system is widely conducted on. There are hardly any research regarding system installation in structure yet. Thus, this paper is conducted by Piezoelectric energy harvesting system and monitoring system installed in university building's hallway and stairs with 50 of two different types of gender subjects. With gathered data from different accumulation of energy between modules, video analysis with footprint distribution ratio of subjects, this paper presents analysed data of different accumulation of electricity with differentiation of module install location along with aspect of accumulation of electricity. Also, this paper predicted the amount of generation of electricity in the same area through analysis of electricity accumulation based on distance between modules.

Recently, development of detailed urban energy consumption prediction tools becomes a rising issue as it can provide more quantitative and qualitative information for planning a sustainable city. One of the target physical phenomena related to the urban case is to correctly calculate the solar irradiance on building envelops with taking into account the shading and mask effects. The sunlit fraction(SF) is commonly used to calculate the effective beam solar irradiance, and the sky-view factor(SVF) is used for the precise diffuse irradiance in the urban context. Both indicators are also employed in this work, and they are calculated using the polygon clipping method. The proposed solar insolation calculation module is implemented in Python, and results from the module are compared with existing SketchUp Plug-in tools. Results show that SF and SVF obtained from the module are almost the same as the existing tools, giving only less than 2% errors over the year. A case study is also carried out for comparison between the urban case and the single building case. As expected, total monthly insolation in the single building case is overestimated with a mean difference of about 20%.

In order to achieve the national goal of greenhouse gas emission reduction in building sector, it is essential that insulation performance of existing buildings should be improved. Because old buildings built before 2001 accounts for 73.2% of total buildings in Korea, when the building insulation regulation was highly tightened. The aim of this study was to evaluate the actual insulation performance of opaque outer walls of old commercial buildings by field measurements. A variety of standards and relevant research which deal with the field measurement of thermal transmittance were surveyed. Outer wall U-values of old commercial buildings were measured and compared with the required value prescribed in the insulation regulation enforced when evaluated buildings were designed. As results, actual insulation performance was found to be approximately two-thirds of required level prescribed in the insulation regulation.
