Han, Young-Hae ; Lee, Tae-Goo ;
KIEAE Journal, volume 12, issue 5, 2012, Pages 3~10
In this study, the influence of decentralized rainwater management over the changes in evapotranspiration was analyzed. The analysis method was obtained by establishing the decentralized rainwater management plan according to different scenarios, and subsequently examined evapotranspiration in the plan. Scenario 1 refers to the analysis of the existing situation, in which was 100% of a parking lot is asphalt pavement. In Scenario 2, the pavement of the parking surface in the parking lot is replaced with lawn blocks. In Scenario 3, some asphalt pavement was removed to establish a flower-bed type infiltration system to allow rainwater to permeate. In Scenario 4, infiltration and storage of rain water would be achieved by transforming the parking surface into lawn blocks, keeping the asphalt for the parking road while establishing a vegetation strip. The amount of evapotranspiration of the target site was analyzed with a water budget analysis program (CAT) using the 2001 meteorological data for each scenario According to the analysis values of S2 and S3, it was found that evapotranspiration is critically affected by the amount of area replaced with pervious area in the total target site. An energy equivalent to 680kWh is required for 1 ton of water to evaporate. Hence, it can be seen that the active inducement of evapotranspiration in urban area makes a positive contribution not only to heat island mitigation, but also to the small-scale water circulation process in a city.

Song, Jeong Seok ; Lee, Hyo Won ;
KIEAE Journal, volume 12, issue 5, 2012, Pages 11~20
In this paper, we analyze the existing ecovillages in order to establish a planned-ecovillage model to suggest improvement in direction of ecovillage planning; namely, efficiency of planning elements through analysis of changes in ecovillages. Changes to living environment require increased relaxation and convenience to ensure quality of life. Unlike general ecovillages, planned-ecovillages differ in their introduction of planning elements by autonomous decision-making through discussions and meetings among residents. In the village planning process, complex planning, community facilities, ecology-base facilities, water-resource utilization, and waste disposal can waver from initial planning, giving rise to realistic alternatives to village characteristics for those considering changes to space organization.

KIEAE Journal, volume 12, issue 5, 2012, Pages 21~27
This study researches the level of satisfaction by apartment building management factor for different characteristics of apartment building residents and seeks to understand the relationship between socio-psychological properties and level of satisfaction. This study is based on a comparative method using a questionnaire by more than 682 housewives living in apartment complexes. Residents of apartment buildings are generally satisfied with housing and management of the apartment building that they are currently living in, but they wanted improvements such as programs that can support community living and increase participation of residents and operation of a web site. Furthermore, it was found that there was a significant difference in terms of operation management, such as sanitation control and processing for apartment buildings and community life management, according to the characteristics of the resident. Also, level of satisfaction in management was found to be influenced by pride and level of satisfaction in relationships with neighbors, showing that management of apartment buildings can have a positive impact on the socio-psychological properties of the residents.

A rental housing has a key role to supply the living space to non-ownership. A public rental housing is particularly aimed at providing the living space for the low-income households with a low rent fee. Therefore, the local government would try to maintain the facilities of the rental housing and to get the decent living condition. For getting the required living condition, it should make a maintenance plan, which contains the repair time, repair scope and targeted component and finishings. This study is aimed at providing the optimal repair time in 12 components and components of the rental housing which is controlled by the local government. The optimal repair time has two steps to get the final result. First, it would draw the 1'st repair time with the probabilistic and empirical approach. Second, comparing the drawn data and the service life, the optima repair time would be provided with considering the components' attributes. Result are as follows : First, the optimal repair time would be considered with the component attributes. There are user's convenience, its safety and physical aspect. Second, the kitchen utensils, elevator and water tap has a optimal time of 16, 19, 17 years respectively which is considered with physical aspect. In addition, the optima repair time of the wiring appliance and lighting equipment are 12 years and 10 years respectively.

KIEAE Journal, volume 12, issue 5, 2012, Pages 35~42
The rental housing has been a main role to supply a living space to the household who can not be available for the home-owner. Specially, the public rental housing is targeted for the low-income household and supplied with low rental fee. Therefore, the rent owner should manage and maintain the housing condition decently with a systematically maintenance plan which includes a repair time and scope, a repair cost. Among them, the repair time is important to make a repair plan. The repair time would be explained with two types, which is divided into a breakdown maintenance and a preventive maintenance. Each of them has a advantage in a repair cost, maintenance of the living condition and provision of the repair scope and method. In this paper, it aimed at providing the repair time in 12 components of the public rental housing which is reflected from a preventive maintenance. This study shows that overall, a permanent rental housing has a longer repair time than any other rental housing in 12 housing components. A public rental housing is closer to the a permanent rental housing then a redevelopment rental housing in repair time. On the other hand, the repair time of the 12 housing components is different form the rental housing. This leads to further study in difference of the repair time according to a tenant type.

This study aims to analyze the green strategies of laboratory buildings in the U.S. developed by LABS21 and LEED of USGBC. To achieve this goal, the paper analyzed the design process of green laboratories and the sustainable planning strategies. Laboratories, as a building type, have specific requirments stipulated by NIH. Chemical restive measures and biosafety level measures needed to be met in laboratory buildings prior to meeting green measures. Obama Admistration's Executive Order 13514 in mind, the paper has mainly focused on the five areas of green planning strategies in the laboratory buildings; site, energy, water, indoor environment, and materials. The study informed that the current green certification program needs to expand into the particular building types in order to; first, provide more realistic energy-saving benchmarking data, and second, provide building-type-specific green strategies.

KIEAE Journal, volume 12, issue 5, 2012, Pages 53~61
As aging society progresses, it is necessary to establish a housing standard that provides a healthy, safe, and convenient environment for the elderly. The objective of the study is to propose a housing space standard that is geared towards elderly living in the urban area. Three steps were taken to attain the objective. First, characteristics of housing preference, spatial usage and furniture preference of the elderly were attained through a survey. The survey was conducted targeting the respondents of the ages 60 to 79 living in three different administrative districts in Seoul. Second, the required floor space to perform individual specific behavior using anthropometric dimension of the elderly was investigated by literature review. Lastly, floor space of each space is suggested combining each area for individual specific behavior which reflects characteristics of housing preference and spatial usage. The results of the research as follows. A bedroom was planned, which includes the function of receiving guests by giving the area for the placement of a sofa. The space for the use of dinning table for two person was planned in the kitchen and The space for the behavior of showering on a chair was planned in a bathroom. Lastly, the space for the behavior of taking off shoes on a chair was considered in the entrance area. Consequently,
is suggested as the necessary floor space for the elderly housing considering the characteristics of the elderly in urban area. However, because of space composition and space for accessibility, the additional space should be considered to plan the elderly housing.

KIEAE Journal, volume 12, issue 5, 2012, Pages 71~76
As reviewed of developments of Korean earth architecture, earth-made buildings have been dwindled gradually since "the new community movement" and earth have been recognized as materials which are not so good to human health and in result, earth-related techniques have been also forgotten. However, recently the earth architecture has been more attracting back many attentions thanks to the people who are interested in health and wellbeing and the earth related techniques or skills got keenly required. The present study has investigated and reproduced earth finishing materials which are based on natural materials as basic stuffs to use them as the finishing materials of the modern earth architecture. For the test, the finishing materials have been divided roughly into sorts of pastes and oils. In case of applying finishing materials onto earth surfaces, the moisture permeability test was conducted to measure a water-absorbing speed, and at the case of using finishing materials for interior works moisture adsorption/desorption test was performed to verify the indoor humidity regulation ability, and further a test to check whether to be stained when contacted with the finishing materials, was conducted. If there is not any stain it might be recognized to be high quality of moisture adsorption/desorption and so seaweed pastes or starches might be used for paste finishing materials and for natural oils, beans are desirable in practical ways. As low-quantity of moisture adsorption materials, linseed oil is most desirable and also beaned water over75% are thought to be useful.

Daylighting is the controlled admission of natural light into a space, reducing electric lighting and saving energy. By providing a direct link to the dynamic and perpetually evolving patterns of outdoor illumination, daylighting helps create a visually stimulating and comfort environment for building occupants, while reducing energy costs. Especially, however, glare is the most important factor in daylighting, which is issued by incoming direct sunlight into windows. This study analyzed the discomfort glare on a daylighting window by using Image processing methodology and found a solution to problems with glare source of occupants. There are several ways to evaluate discomfort glare such as UGR (Unified Glare Rating) of CIE, DGI (Daylight Glare Index, Hopkinson, 1972) and VCP (Visual Comfort Probability) of IES. These are used to apply to the relatively little artificial light source and they cannot cover discomfort glare from a real daylighting window. In this regarding, this paper aimed to calculate DGI index of the real daylighting window in a experimental space by using image processing methodology. The variables and outcomes are luminance distribution of non-shading window, effect of venetian blind installed on the window and locations related to position index of DGI.

Kim, Hyeon Soo ;
KIEAE Journal, volume 12, issue 5, 2012, Pages 85~92
This research was executed to analyze the problems of Korean type of 'Light-weight' Greening that has been applied similarly by the type of 'Intensive Greening,' and to suggest the better way. To achieve this purpose, we compared and analyzed the theory about the definition of Korean type of Roof Greening and the type of Greening of FLL. And we researched documents and fields of 18 sites of Seoul City that applied the type of 'Light-weigh' Greening, and produced improvement issues and directions. To resolve the confusion of the type definition and site application, arising from considering 'weight of greening' as the main viewpoint to classify the type of Greening, we have to change the term 'Light-weight' with more suitable for contents-based definitions. According to a 'Light-weight' Greening field survey, only 5 among 18 sites are suitable for Extensive Greening and the rest sites show the character of Intensive Greening. Korean concept of 'Light-weight' Greening corresponds with the definition of 'Weight of Greening', but has a problem that does not correspond with the viewpoint of 'Maintenance of Greening'. This problem comes from the fact that the surveyed Light-weight(extensive) Greening sites are designed and executed for use. Therefore, Extensive Greening is proper to be applied for sites, excluded from use. 5 sites, determined suitable for Extensive Greening, adopts 'Sedum-herbaceous Planting' or 'Sedum-grasses Planting' forms of Greening, based on Sedum. So, it has to precede with selecting and breeding plants for developing various forms of Greening, suitable for Extensive Greening including 'Grasses-herbaceous Planting.'
Mechanical Properties of High Strength Shear Connector
Eom, Chul Hwan ;
KIEAE Journal, volume 12, issue 5, 2012, Pages 93~98
The headed studs those are used extensively for steel-composite construction is specified as SS400 at the current Korean Standard specification considering the welding condition. And the corresponding equation for the shear force calculation is limited for the use of compression strength of concrete below
. However, it is expected that the high strengthening and precast of both steel and concrete due to the necessity of shear connector or other connecting material for the combination of steel and concrete. Therefore, the experimental results obtained during the development process of high strength stud for the connection of high strength concrete and the steel member are reported in this paper. Also the effectiveness of newly developed shear connector using pipe to increase the stiffness of a stud is verified by comparing both the stiffness and the strength with common stud bolt through the welding ability, mechanical characteristics and experimental investigation.
