Quantification of infiltration rate is an important issue in HVAC system design. The infiltration in buildings depends on many uncertain parameters that vary with significant magnitude and hence, the results from standard deterministic simulation approach can be unreliable. The authors utilize uncertainty analysis In predicting the airflow rates. The paper presents relevant uncertain parameters such as meteorological data, building parameters (leakage areas of windows, doors, etc.), etc. Uncertainties of the aforementioned parameters are quantified based on available data from literature. Then, the Latin Hypercube Sampling (LHS) method was used for the uncertainty propagation. The LHS is one of the Monte Carlo simulation techniques that is suited for our needs. The CONTAMW was chosen to simulate infiltration phenomena in a residential apartment that is typical of residential buildings in Korea. It will be shown that the uncertainty propagating through this process is not negligible and may significantly influence the prediction of the airflow rates.

As outdoor environment become worse due to concentration of population in large cities, the importance of environmental control strategies such as the arrangement of green space or water space and ventilation paths, has been increasingly recognized. However, most of the studies focus on the assessment on outdoor thermal environment, few studies focus on the interrelationship between thermal environment in residential block and human thermal comfort. The aims of this study is to develop the outdoor planning method to reduce the heating/cooling load in an apartment unit or entire block by the sustainable approaches in outdoor environmental design. In this paper, on the basis of the prior studies, the effect of the outdoor thermal environment on human thermal comfort will be analysed.

Currently, effective energy management of buildings is necessary because of accelerated global climate change and resource crisis. Especially, in the case of South Korea, city gas consumption occupies 11.8% of the total energy and 39.6% is residential use among them. Therefore, for reducing the city gas consumption, the effectiveness of residential use is needed. To address this issue, the objective of this study is to analyze the difference of the city gas consumption according to the space arrangement in the apartment building. To achieve this objective, an apartment complex having over 1,000 households was selected then, according to the space arrangement such as south-east and south-west, the data of 59.97m2 and 84.96m2 were analyzed by using statistics method. As a result, in 59.97m2 and 84.96m2, the total city gas amount in 2012 showed that 9.2% and 8.4% were more increased at south-west than southeast respectively. In the future, the findings of this study can be used to develop the prediction model of city gas consumption in apartment building.

Architecture is the historical record of a society. Residential culture is one of the cultures, and includes all the living and customs of people living in the current society. In particular, the Native residence has the research value of changing the living culture because it contains the lives of farmers. The residential culture of the Korean-chinese people contains the poor, agricultural, and immigrant life that began as a livelihood. Therefore, residential culture is an important part of the Korean-chinese culture. However, due to population movement and urbanization, the deepening and aging of the rural community caused the destruction of the residential culture, and the residentials that had been vacant for many years were destroyed, and a large number of risky residential reconstructions are underway. At the point of progress from a voluntary personal building culture to a public building culture built by the government, a study on Renovation of dilapidated Building and a more reasonable residential reform plan is needed. Our housing culture should not only improve the living environment of current life, but also inherit the housing culture contained in history.

This study is about occurrence pattern of vacant spaces as a urban decline indicator to consider a decline of old hillside residential area from spatial structure perspective. For investigation based upon vacant space and the street structure, this study selects Ami Chojang-dong in Seo-gu, Busan, of which 79.7% of total area is over a gradient of $10^{\circ}$. Focused on relationship between occurrence pattern of vacant spaces and 'vertical alleys(link)' serving as main movement path of local residents in hillside residential area, the length, numbers, slopes, and use characteristic of vertical alleys were analyzed using Arc GIS 9.3 program to classify characteristic zone types of spacial structure in hillside residential area. After the occurrence pattern of vacant space are interpreted in relation with building density, vertical alleys' number length slope, the social and economic issues have been considered as well. After analyzing the occurrence pattern of vacant space, this study argues that the occurrence pattern of vacant space in old hillside residential area is rather affected by street structure system consisting of vertical alleys than the impacts of social economical issues.

This study analyzed the physical characteristics and change characteristics of urban detached residential area. In the reality of South Korea in which the history of modern urbanization is not long, the densification that progressed together with sudden population growth without any consideration of city plans became to reveal many problems. Thereafter, apartment-centered large scaled development plans have been implemented until now as an alternative for the foregoing. As the residential environments of old downtown areas that were excluded from the development have been gradually deteriorated, large scaled re-development and reconstruction projects have been adopted as ways to solve the problems of the old downtown areas. On one hand, the development methods that damage the history of the detached housing areas have been resisted. With such a background, this study attempted the analysis of the change characteristics of the Kookmin Housing Complex in Suyu 1-dong, Seoul with a view to playing the role of evidentiary materials for the disappearing urban detached housing areas or those urban detached housing areas that may be revived. This author hopes and the results of this study will lead to careful development that presents measures to maintain and develop modern urban residential areas where the history of past residential areas and culture are disappearing due to full-scale redevelopment.

Previous research on super high rise buildings focused mostly on the use of public space from building plan perspective, survey of residents' satisfaction evaluation, construction technology and structural technology. But little research is done on the economic analysis of landmark factors. The purpose of this study is to find landmark factors that can be quantitatively measured, collect data on super high rise residential buildings in Seoul. Find the intrinsic values of the landmarks, and analyze how these values differ in areas with different densities, i.e. in 3 Gangnam-gus & Yeongdeungpo-gu and in other areas. It is expected that the results of this study can be used to set an appropriate price of super high rise building in consideration of its landmark value in different area

This research was to analyze the direction ideas of residential Feng Shui. In ancient China residential places were been established by Xiangzhai(相宅) and Buzhai(卜宅) usages. And ancient Chinese always considered geographical features of mountains and waters for setting up their living places. Geographical features were also considered importantly ih representative residential Feng Shui books, Zhaijing(宅經) and Yangzhaisanyao(陽宅三要). In Zhaihing, 24 direction ideas are co-related with Fagui(八卦) and GanZhi(千支) theories, and they are most important residential Feng Shiui direction theories. The basic thoughts of 24 direction ideas of Zhaijing were already formed in Qin(秦) dynasty and modified in early Han(漢) dynasty. In Zhaijing, residential places were splited into Yangzhai(陽宅) and Yinzhai(陰宅) according to YinYang's Qi directions. Those were actually formed from meticulous observations on changing processes of YinYangWuXing(陰陽五行)'s Qi(氣). Constantly changed Qi of YinYangWuXing were studied by old chinese people from the observations on the sun, the moon, the five stars, the Great Bear, and ErShiBaXiu(二十八宿). The origin of Zhaijing's direction ideas is the direction system of ShiPan(式盤) in Qin and Han dynasty. On ShiPan TianGan(天干) Dizi(地支) Fagui TianDiRenGui(天地人鬼) were arranged very systematically into four and 24 directions. DongxiSizhai(東西四宅) theories of Yangzhaisanyao had edited more lately than Zhaijing(宅經), and formed according to Fagui(八卦)'s YinYang(陰陽) principles. But the basic ideas is same with Zhaihing's. It proves that residential Feng Shui theories were constantly improved and modified. And both residential Feng Shui direction ideas of Zhaijing and Yangzhaisanyao are the gentral ideas in old china. The point of that ideas is Sky's four or 24 directions are correspndence with the earth's. It came from the traditional thoughts that Heaven, Earth, and mankind are c0-related and influenced each other according to Qi's changing processes. Gather up above mentioned, the direction ideas of residential Feng Shui is a systematic thoughts of old chinese for harmonizing Tian-Di-Ren-Gui, and is their specific methods for harmonizing the nature's Qi, mankind and spirits.

This study was focused on the new town residential complex in suburban Hefei, China, which was carried out a survey on the present conditions of children's play space. The residential complexes and play spaces in Hefei, regardless of installation, the standards for the installation of play facilities were not provided legally, and the types of installation of the play facilities also were not standardized. For the play space in residential complexes in China to carry out original functions under the condition and become a place of everybody's activities not just for children, the following should be improved:(1) There is no provision and standard for the size of play space, so the standards for installation of play space with safety like Korea, Japan and the US are necessary. (2) The location of the play space should be able to guarantee maximum play activities to children, and the independence of the space should be secured by putting it in a place far from a footpath or pass way. (3) Since children's play space has different properties from those of green space and resting spaces, separate environmental planning is necessary.
