KIEAE Journal, volume 10, issue 3, 2010, Pages 3~10
As indoor air quality directly affects health and comforts of the residents, researchers from different countries have continued to explore criteria by which indoor air quality can be indicated in a scientific and quantitative manner over the past several decades. However, there are many possibilities that can deteriorate indoor air quality. Due to the uncertainty of influence factors, it is quite difficult to develop a correct evaluation model and quantitative method. Furthermore, the effects from the indoor air pollutants have different levels, leading to the difficulties to apply the regular standard. This study aims to propose evaluation criteria by using the FD-AHP analysis. Obtained findings will be beneficial to construct apartment buildings, commercial buildings and others health performance evaluation framework.

This study aims at exploring the characteristics of the Usonian houses of Frank Lloyd Wright from an ecological viewpoint. After considering the definition and application of ecological architecture through literature review, 28 Usonian houses were selected and analyzed for the study. Also, nine Usonian houses, which clearly have ecological and historical importance, were visited and more thoroughly analyzed. The result shows that Usonian houses are ecological in terms of 1) the relationship among nature, landscape and house, 2) the orientation, natural light and natural ventilation, 3) the use of natural local materials including wood, stones and bricks, 4) the use of floor heating (the On-dol system inKorea), 5) the human scale, 6) the use of the board and batten unit (an early system of prefabrication), and 7) the openness and flexibility of floor plans.
The Conservation of Historic Environment: Comparative Analysis of Conservation Charters and Principles
Chung, Seung-Jin ; Kim, Chang-Sung ;
KIEAE Journal, volume 10, issue 3, 2010, Pages 27~35
It has been criticized that the Venice Charter of 1964 characterizes so much of Western value of architecture and its conservation, despite its significant contribution towards an international conservation approach. Since the 1970s some countries have drawn up their own conservation guidelines to supplement the limitations of the Venice Charter. When we review critically those documents, we find a change in the Western dogma of heritage. Although the Burra Charter of 1979(last version in 1999) and the China Principles of 2002 accept the general philosophy and concepts of the Venice Charter but make responses to special local needs. The Burra Charter has redressed a current Western bias which has permeated global conservation practices, responding to the Australian context. The China Principles also meet special national needs but in accordance with recent international practices. For this reason, the Burra Charter and the China Principles are regarded as well established in national conservation practices but also as representing each country's contribution to contemporary international conservation practices.

KIEAE Journal, volume 10, issue 3, 2010, Pages 37~42
Together with the concern about the indoor air quality as sick house syndrome, the Ministry of Environment announced "Indoor Air Quality Control Law for the Multi Purpose Facility," which made the interests to be focused in the urgent understanding of current condition and preparation of measures about the indoor air pollution. The law was revised to obligatorily notify the amount of Formaldehyde and Volatile Organic Compounds in the case of newly constructed apartments with more than 100 houses. School also have its own indoor air quality guideline. Indoor air quality in school is very important because, children who very weak to indoor pollutants reside long time in there. The purpose of this paper is to to survey indoor air quality in school by field measurement. Field measurements were performed in 11 schools which were selected from 3 major cities(Incheon, Dae-jeon, chuncheon) in korea, Totally concentration of indoor pollutants were determined in 32 classroom. Target air pollutants were TVOC, formaldehyde, dust, CO, CO2. For the result of this investigation, Indoor air quality in classroom was very poor and it was found that some pollutants(TVOC, float bacteria) exceed the guideline.

Natural lighting is directly connected with our mental and physical health. For working or learning effect, the proper natural lighting is required for improving our living conditions. School facilities, especially, are the place where includes students' ordinary activities with learning behaviors during the school years from elementary to high school. This study was carried out for the purpose introducing a basic database in that planning a school by researching on the actual in the natural lighting system of some schools' classroom, estimating, and analyzing through a simulation, which resulted in a method of improving the natural lighting system. As a result of measuring and analyzing Daylight Factor(DF) during the time from 9 am to 3 pm when students are activating in their classroom, generally DF range of the sides near to window and aisle seats zone are not distributed well. Besides, two out of four school which are researched would not reach the standards of the law for school sanitary while rest of the schools meet the standards; Average DF 5% and Minimum DF 2%. And the result of a simulation by RADIANCE program shows the most appropriate DF range when it is applied in variable numbers about an oriehows the- South-east 15, south-east 30, south-east 45, south-west 15, south-west 30, and south-west 45 degrees. When it is applied in the variable numbers about glass transmittance - 60%, 70%, and 80% in condition facing south of a classroom, the result shows that the DF range of 80% transmittance is relatively higher than other glasses in the classroom. Thus, when a school is built, plans for an orientation is necessary for improve of elementary schools' environment with the glass installation which is made for high transmittance and is regarded with the students' activities time.

The sound insulation performance is one of the important factor that determined the amenity of housing life in residential building. Especially, Apartment house represents a korea habitation. So the importance of privacy and noise problems between habitable rooms are emphasized in these habitation. This study investigates and find a problem of sound insulation performance of partition wall of the apartment house in current state. The measurements were carried out in apartment house with and without a stair hall. And the measurements also carried out in current state and installing a sound absorbing material in receiving room and changing a front door and installing a inner door. In spite of the same partition wall, difference results were showed according to the stair hall. It is appeared that sound insulation performance without stair hall is 6-7dB(Dw) higher than that with stair hall. In case of without stair hall, sound insulation performance is Dw 49 for single number quantity for airbone sound. And In case of changing a front door and installing a inner door sound insulation performance is Dw 57 for single number quantity for airbone sound. The Results of measuring on the changes a front door and installed a inner door indicated that the flanking sound through front door influenced the sound insulation performance.
Development of a Spatial Subdivision Technique using BIM for Space Syntax Analysis of a Korean Traditional House
Jeong, Sang Kyu ;
KIEAE Journal, volume 10, issue 3, 2010, Pages 57~62
To effectively use Building Information Modelling (BIM) dealing with semantic information including the entities of building components, the information about building components should be standardized. Like standardized modern buildings. in the past, Korean traditional houses were built according to strict procedures and formats. Therefore, if the Korean traditional house are modelled by using BIM,. not only the Korean traditional house of good quality will be built quickly and cheaply, but also spaces in the existing Korean traditional house will be easily analyzed. However, when analyzing spaces of the Korean traditional house using Space Syntax, some problems are caused in dividing outdoor space such as yard with unclear boundaries, unlike indoor space with clear boundaries surrounded by walls. These comes from the fact that researchers have subjectively divided a space in the house into convex spaces as units for Space Syntax analysis. Therefore, this study aims to develop an objective and rational spatial subdivision technique for Space Syntax analysis of a Korean traditional house modelled by using BIM. We could objectively and reasonably divide a Korean traditional house space into convex spaces by recognizing the building components in the house modelled in the form of Industry Foundation Classes(IFC). Depending on the connection of convex spaces allocated in the spatial subdivision technique, j-graph in Space Syntax could be drawn and the measurements of spatial configurations could be determinded. Through the developed technique, the social properties including the cultural and philosophical aspects of Korean people was identified by measuring the spatial configurations of Korean traditional house. The developed technique will serve as useful means to help architects to find an appropriate purpose of each space for sustainable architecture on the basis of the spatial and social relationships in buildings or urban systems.

The general housing causes various environmental problems on the squandering of the resources and the production of the construction wastes, as it was removed and rebuilt because of the short-life in 20-30 years after constructing. The short-life of the general housing makes the rebuilt-term short and takes a negative attitude in maintenance. In the other hand, the long-life housing is constantly dwelling house that considers the carbon reduction among the world issues, Support and Infill. The long-life housing promotes the durability of Support and maximize the variability of Infill through separation of Support & Infill. It's useful dwelling house in maintenance as well as various life-cycle and life style. As the maintenance guideline of dwelling house is used for long-life housing, there is not distinction considering who controls maintenance and there is not conception considering alteration, variability and convenience. Consequently, it is required to develop the proper maintenance guideline applied maintenance process for long-life housing. Therefore this study shows efficient maintenance guideline for manager in long-life housing.

In comparison with ordinary or heavy-weight concrete, light-weight air void concrete has the good aspects in optimizing super tall structure systems for the process of design considering wind load and seismic load by lightening total dead load of buildings and reducing natural resources used. Light-weight air void concrete has excellent properties of heat and sound insulating due to its high amount porosity of air voids. So, it has been used as partition walls and the floor of Ondol which is the traditional Korean floor heating system. Under the condition of which the supply of light-weight aggregates are limited, the development of light-weight concrete using air voids is highly required in the aspects of reduced manufacturing prices and mass production. In this study, we investigated the physical properties and thermal behaviors of specimens that applied different mixing ratios of foaming agent to evaluate the possibility of use in the structural elements. We proposed the estimating equation for compressive strength of each mix having different ratio of foaming agent. We also confirmed that the density of cement matrix is decreased as the mixing amount of foaming agent increase up to 0.6% of foaming agent mixing ratio which was observed by SEM. Based on porosity and compressive strength of control mortar without foaming agent, we built the estimating equations of compressive strength for mortars with foaming agent. The upper limit of use in foaming agent is about 0.6% of the binder amount. Each air void is independent, and size of voids range from 50 to

Carbonation is one of the major deterioration factors for concrete. So. lots of researchers have proposed the equations for determining carbonated depth and the initial time of steel corrosion due to carbonation to predict the service life of concrete structures. However, there are large gaps among the equations for predicting carbonation because each researcher has different considering factors to predict carbonation depth. So, in this study, we calculated the deviations of the proposed equations for carbonation, and we calculated each researcher different corrosion initiation time. However, it has a lot of deviation. Therefore, we evaluated the probability of steel corrosion considering each deviation using MCS, an analysis method based on probability theory. In the results, we have proposed much advanced information for determining service life of reinforced concrete structures due to carbonation.

Entering into the 21th century, the whole world is facing the various problems such as environmental disruption, resource exhaustion, and social isolation due to the consequences of population growth and economic development. Especially, as the world population is aging, the solutions for these problems are being suggested with a new paradigm of environmental design for sustainable society providing more affluent and safer life for them. Aging societies are experiencing the difficulty in pursuing persistent vitality of life when aged population is socially excluded, and communities are stagnant due to the decrease of economic activities. In other words, those factors are causing the problems of social sustainability associated with the vital duration of local society and communities. In order to develop successful environment for aging society, it is necessary for us to precisely review how advanced countries are changing their directions. Therefore, the purpose of this study is to examine current trends of the aging friendly environment and find out the measures to promote social sustainability under the crisis of aging society. For this purpose, using qualitative methods, this study analyzed the contents presented at a professional conference
, that showed current trends clearly, into three dimensions of social sustainability; the social integration of senior living communities with local society, the vitality of the communities, and the invigoration of individual senior lives. As a result, this study found that the measures that attempt to enhance the social sustainability of aging population can be also used to invigorate the communities.
