  • This project located in IFEZ(Incheon Free Economic Zone) is the first central heating and cooling type for high-rise residential building in korea. The design was performed as the joint venture between Cosentini from U.S.A and wooowon, and our design concept was to save energy. LEED application from USGBC is going on in progress for the first residential building in korea. Careful attention was paid from schematic design for not a durability of structural and architectural, but also durability and safety of M.E.P.

  • A comfortable indoor environment is important considering that many hours are spent in residential or office space. A humidifier is used to control the indoor humidity. In particular, an element type humidifier has the advantage of a simple structure and low energy consumption. Two types of humidifiers - stationary or rotor - are commonly used for residential purposes. In this study, performance optimization was conducted for a rotor-type humidifying element used in a residential humidifier. The optimization included the rotation speed, water submersion depth, etc. The test range consisted of an open area to the air from 57 to 90%, rotation speed from 0.2 to 2.0 rpm, frontal air velocity from 0.5 to 2.5 m/s. The results showed that the optimal open area to air was 70%. On the other hand, the effects of the rotation speed on the moisture transfer rate was negligible. On the other hand, the pressure drop increased with increasing rotation speed. As the frontal air velocity increased, both the moisture transfer rate and pressure drop increased. The humidification capacity of the present element was 0.08 ~ 0.31 kg/hr. A comparison of the data with the theoretical results was made.

  • This study investigates supply patterns and residential characteristics of the Urban-type Housing in Seoul. There have been 3,336 buildings and 71,790 housing units approved until the end of 2012. One-room apartments and small units less than 30 $m^2$ of residential area amount to 81% and 82% of total units, respectively. Major findings are as follows. First, single- and two-person households less than 30 years of age are mostly lived in the housing. Respondents are mainly professional and white-collar (43%) and service and sales workers (27%). Most of them are mid-income classes (67%), which is twice more than that of single- and two-person households in Seoul. They pay 672 thousand won in rent more than average rent of mid-income class. The rent to income ratios are 29.9% for single households and 24.5% for two-person households, which are higher than that of mid-income bracket. Third, their satisfaction level is relatively high in internal environment and access to public service facilities, but not in external environment and community service facilities. They are satisfied with security and daylight, walking and safety, access to public transport and parking space, but not with noise and vibration, natural environment, access to park and cultural and sports facilities, and most community service facilities. It is necessary to reexamine the articles of deregulation and prepare design standards while considering different housing and locational types.

  • The purpose of this study is to analyze the residential space composition and extension of Jeonja-jip and Dureong-jip in Samcheok region. The results of this study are as follows. It appears three residential plan types - Jeonja-jip with Anmaru(a room made of wooden floor), Jeonja-jip without Anmaru and Dureong-jip with Anmaru- in survey region. It was needed the extension of residential space at Jeonja-jip(a house type with two-row rooms which be composed of 田type under one roof) and Dureong-jip(a house type with inner floor which be surrounded by rooms under one roof) because of shortage of sleeping space, working space and keeping space owing to growing large family. The solutions of these shortages will be the extension of space in houses. Jeonja-jip's basic type which is the Kyup-Jip(a house type with two-row rooms under one roof) of 一 type with 6 Kans(Kan, a unit to count room to divided with four posts) is transformed and extended to 田shaped house with 11 Kans toward X-axis orientation. Dureong-Jip's basic type which is ㄱ type with 7 Kans is transformed and extended to the Sekyup-Jip with 9 Kans and the Nekyup-Jip(a house type with four-row rooms under one roof) with 12 Kans toward Y-axis orientation by insertion and addition. Jeonja-jip was developed into Kyup-Jip with front 4 or 5 Kans and side 2 Kans instead of being done into Sekyup-jip or Nekyup-Jip with insufficient day lighting and ventilation problems. Jeonja-jip and Dureong-jip were stronger than any other traditional houses in tendency to reserve Magu(cowshed) and Chikkan(toilet) in a house.

  • This study conducted a survey 361 immigrants by Cheongju Yullyang II Land Development Projects of Chungbuk, Multifunctional Administrative City Construction Projects and analyzes the factor which affects their residential satisfaction. The result of study is as follows. The level of subjects' residential satisfaction is 5.35(SD=1.33) which is average. By looking the level of related factors which affect residential satisfaction, the levels of facilities region and residential environment region are normal. The levels of housing environment and trust of development are lower than the normal. To figure out the factor which affects residential satisfaction, a regression analysis is conducted. The result showed that age of research subject, family type, residence period, physical status, owner or renter, housing environment region, facilities region, residential environment region, and trust of development among factors related to residential satisfaction affect the residential satisfaction. Based on these results, several ways are suggested to improve residential satisfaction of the immigrants.

  • The intent of this study is to investigate the feasibility of small-scale developments in residential blocks in the city, and to propose development strategies and models. This research is done on the premises that large housing developments ignore the urban structure of its own quality, whitens on-lot-based multi-unit housing developments fail to maintain amenity and livability in residential blocks. For solving these shortcomings, this research proposes the possibility of small-scale housing development models as an alternative development system. And some residential blocks were selected as case sites and analyzed into typical block types, to support the proposal of pertinent development types. Each type was investigated and discussed in terms of development feasibility and proper development strategies. Finally, three development schemes are proposed as prototypical models for the best application in residential blocks.

  • Energy consumption in Korea and Japan has already progressed to high level. Especially, it will be important to take up the effort to achieve further energy savings in residential sector that has significant increase both nations. For this reason, research for energy consumption and saving method in residential sector compare Korea with Japan that of similar data to grasps the direction for energy savings. In addition for introduction of distributed energy system to residential sector, such as apartment house, the electricity and gas demand was simulated. To be more specific, several key characteristics were studied, such as housing type housing scale and width of common space.

  • The impacts of electric service interruption to customers depend on customer and interruption characteristics. Customer characteristics include demographic aspects(residential type, and number of household members) and power supply types whereas interruption characteristics include frequency, duration, time, and day of interruption. Accordingly evaluation of these customer interruption costs is very complicated and subjective. For residential customers, customer survey method seems most appropriate because interruption impact to residential customers is intangible. In other words, the value of housework or lost leisure due to interruption is individual. Accordingly, this paper selected the customer survey method to assess the interruption costs for residential customers.
