The characteristics of Japanese housing stock is as follows. 1. It is predicted that population from 2010 and general household from 2015 will decrease. The aging speed in Japan is faster than several advanced nations. 2. Housing shortage has resolved from 1973. In 1998, dwelling number per household is 1.13 houses and vacant dwelling rate is 11.5 percents. 3. Dwelling level of rented dwelling is lower than owner occupied houses; for instance, floor area of the former is one third of the latter. As for a household of thirties, family type household lived in rented houses reached 60 percents, it reveals that the demand exceeds the supply. 4. Houses constructed before the new earthquake resistant standard enforced from 1981 year is the half of the whole, housing improvement is needed in the future. Future housing market is changed to practical use of housing stock. Consequently, expansion of multi-habitation used a vacant housing of city dwellers, activation of the used houses distribution, growth of dwelling reform market, and activation of the rented houses are expected.

Although Feng-Shui has been widely used in architecture and urban design and planning for thousands of years, it has not been properly studied as a scientific and thus rational approach. Feng-Shui has been recognized as an environment-friendly design and planning method in recent years due to its thoughtful consideration on the harmonious relationship between architecture and the natural environment. This study investigates its major principles and techniques that have been widely used in the design of houses through previous relevant researches. Then, the principles and techniques that are relevant to the residential uses are indexed for the quantification of Feng-Shui. Ten Feng-Shui indices are formulated and each index is quantified to make five points for a perfect match. These indices are then tested on three different types of house in Korea, namely traditional Korean houses, contemporary Korean style houses and contemporary architects' houses. The result shows that the first type of house records the highest Feng-Shui points and then the second and third types in that order. This result convinces us that the Feng-Shui indices can very effectively represent the degree of environmentally friendly design.

Nagaya is one of the traditional Japanese housing types in which multiple houses are attached together. In Nagaya, walls are shared by several houses but entrances are privately owned by houses. Nagaya consists of many wooden houses for common people located in parallel with narrow alleys between them. Nagaya was one of the representative housing types in Japanese architectural history. This research is to study the background of the origination of Nagaya in Japan, the characteristics of space and land planning, the features and causes of the changes in the space and land planning. In this research, we observed and analyzed unit plans of a block of gate-type Nagayas in Hanan, Osaka. The results are as follows. First, as the inner alleys(Roji) are closed, the number of entrances to each housing lot decreased from two to one since one entrance that used to be open to inner alleys(Roji) are permanently closed. Second, walls between streets and housing lots which used to be one of the outstanding characteristics of gate-type Nagayas are disappearing. Third, as the bathrooms are added to houses, the front gardens are being degraded to empty spaces or sometimes totally removed. Fourth, the space in the first floor of houses become family spaces, and that in the second floor is divided into private rooms for individuals.

The purpose of this study is to analyze the state-of-the-art daylighting design among LEED(Leadership in Energy and Environmental Design) multi-family housing cases and to explore the feasibilities for their applications in domestic housing design. Occupants in multi-family houses are reported to consume more electricity power than those in single houses. That may imply the problems of daylighting design in domestic housing design for multi-family houses have better insulation system and less windows and outside walls than single houses. Therefore two systems, daylight delivery system and daylight control system, are scrutinized for daylighting design with LEED cases. The findings show when windows as a daylight delivery system are combined with overhangs, fins, louvers, fenestration materials, speciality fenestration, or interior controls as a daylight control system, the outcome goes with more energy savings and better facade design. Beside those, lightshelves as a daylight delivery system seem to have potentials in domestic multi-family houses with deep plans and less outside walls. Daylighting designs in domestic multi-family houses need to pursue available options more to achieve the integration of energy and aesthetics values.

This study aims to analyze exterior spatial characteristics of the detached houses in Korea which were designed by professional architects. For this, plans, pictures and data of 113 houses which appeared in architectural publications from July 1998 to June 2002 were collected and analyzed. The results of the study are like this. 1) For the shape of buildings, the number of the non-rectangular shaped buildings is higher than that of the rectangular shaped ones. ; 2) For the location of exterior gardens, the number of the houses with front gardens is higher than that of the houses with back gardens. The exterior gardens are mostly accessed from the living rooms. 3) For the interior gardens, 50% of the surveyed houses have this type of gardens. They are mostly located at the back of the living rooms. The interior gardens are mostly accessed from the living rooms, dining rooms and corridors respectively. 4) For the terraces which are located in the 1st floor, they are mostly accessed from the living rooms. : 5) For the balconies which are located in the 2nd floor, they are mostly accessed from the bedrooms.; 6) For the location of the entrances, they are mostly located in the front side of the buildings and mostly facing south.

Though they have advantages in terms of aesthetic in modern architecture, however, rectangular-shaped towers causes being short of natural light due to deep interior space. There are compromised attempts to take advantages of each building shape selectively. As a result, we now witness the advent of Y-shaped, T-shaped, V-shaped and ㅈ-shaped buildings on the market. The mutative type of apartment houses usually faces southwest or southeast, which has lot of daylighting availability but anyhow, the proportion of the apartment houses which have a full south aspect. The need to verify the potential of daylighting in new building-block shapes exists. At the same time, the expansion of balcony area was legalized and thus, a visual buffer area does not exist any more. All-glass window wall on apartment houses without a balcony produces pretty harmful area with direct sunbeam. Recently, the refurbished version of conventional windows has been developed for the purposed of minimizing energy loss occurred around windows. This research initialized a series of research to deal with almost all on window wall for apartment houses. First of all, huge amount of already-designed examples of apartment houses have been analyzed in terms of floor plan, elevation, orientation and glazing materials.

The purposes of this study were to make clear the present condition of the TVOC and HCHO concentration after renovation in apartment houses. The field measurements of TVOC and HCHO concentration according to the Korea Test Method Standard for Indoor Air Quality were carried out in 4 subject apartment houses. The results are as follows; the TVOC concentration after renovation in apartment houses ranged from mean 0.35ppm to mean 5.08ppm and increased of $0.35{\sim}5.08ppm$. The TVOC concentration of 3 subjects exceeded the Indoor Air Quality Management standard for the newly-built apartment houses (0.58ppm). The HCHO concentration after renovation ranged from mean 0.13ppm to mean 0.43ppm and increased of $0.06{\sim}0.26ppm$. The HCHO concentration of 2 subjects exceeded the Standard (0.17ppm). As results of analysis on the relation of concentrated ascension and renovation elements, the amount and the types of finishing materials and adhesives affected concentrated ascension. Also, production method for installed or purchased furniture had certain effect on the TVOC and HCHO concentration ascension.

This study examined and analyzed locational conditions of apartment houses in regional small cities to provide basic materials to set direction and index of view management of apartment house and thus the results of the study are as follows. 1. The number of story of apartment houses 'below five story' was 48% and area of apartment house was 'over 500m$^2$ and below 1000m$^2$' in 31% of the whole regions. 2. As a result of analyzing correlations with changes of floor of apartment house by construction year, apartment houses below 10 story were mainly built between 1991 and 1995 and high-storied apartment houses over 11 story were mainly built since 1995 and apartment houses over 21 story were built since 2000 and these high-storied apartment houses were main cause of hindering view of small cities. Accordingly, establishment of guideline of building high-storied apartment house which can be a primary obstacle of urban view and regulations of height are needed.

Analysis data of basics which are used for LCC(Life Cycle Cost) analysis of buildings and maintenance plan, are demanded to secure according as replacement cycle of repairs of apartment houses has come. However, investigation techniques and systems for investigating condition of deterioration of apartment houses, have not been made yet in Korea. For this reason, this study was wanted to make investigation techniques and systems, so the process for maintenance of apartment houses was researched and the required quality and deterioration factors of interior/exterior materials were investigated. As a result Check-List for investigating condition of deterioration, was made. if this is used during a nonscheduled, a routine, a regular and a urgency check, the methodical investigation will be achieved. Furthermore, if this is used for maintenance of apartment houses, it will be helped to select the repair cycle and the long-term repair plan.

In the middle of 1940s, Hassan Fathy, a great Islamic contemporary architect, built cheap multifamily houses, schools, mosques and public market in the village of Gourna, near Luxor, Egypt for the poor Egyptian. At that time the western style houses made of concrete materials were so expensive for the Egyptian people in the rural area, that Hassan Fathy, a young architect, challenged to build the houses for them. He considered seriously the expenses that the lower-class Egyptians in the rural area could pay for building houses. He built up gorges arch-style building and done-style building by using traditional materials, which consisted of reeds, roues and mud brick for adobe. He made the design of houses cool in summer and warm in winter. The houses in the Gourna village were, afterwards, highly evaluated, in the sense that they represented the Islamic uniqueness of architecture and its beauty. As a result, the Gourna village made him receive many of awards including the Aga Khan Award. This study tries to focus on the reviewing of modern Islamic architecture by analyzing Hassan Fathy's architectural art, on the investigation of traditional materials used for building the Gourna village, and finally on the contribution for the research of Islamic architecture
