This study examined whether the Fair Housing Amendments Act of 1988 (FHAA) in the US provides more home accessibility features and reduces the home accessibility problems of senior residents with physical disability. The 2011 American Housing Survey data with a sample of 2,326 senior residents age 55 and over with physical disability and living in multifamily housing built between 1970 and 2011 were analyzed. We compared senior residents living in multifamily before (1970-1990) and after (1991-2011) the FHAA. The results show that senior residents living in multifamily housing before the FHAA were at a greater disadvantage because they were more likely to live in older buildings located in urban areas, yet paid lower rent and received government subsidies. This study confirmed that the FHAA enabled residents of multifamily housing to have more home accessibility features. However, there was no significant difference in perceived home accessibility problems between the two groups, indicating that senior residents in multifamily housing have experienced home accessibility problems both before and after the FHAA. This study has important implications for housing policy makers to consider home accessibility features for multifamily housing buildings before the FHAA, and to revisit if the FHAA sufficiently compensates physical disability of senior resident living in multifamily housing after the FHAA.

This study proposed how to identify window defects by using photos uploaded by occupants during the pre-handover inspection of mulch-family housing. A total of 1168 door images were acquired to generate training data and validation data. Subsequently, through the proposed algorithms, every pixel in images labeled a door was binarized using the OTSU threshold, and then dark pixels were identified as defects. Experimental results demonstrated that our computer vision-based defects identification method detects the door with a recall of 57.9%, and door defects with 63.6%. Although it is still a challenge to automatically identify building defects because of the distortion and brightness of photos, this study has the potential to support better defects management. Ultimately, the improved pre-handover inspection may lead to increased customer satisfaction.

A traditional Korean housing is a typical type which is contained life style, spatial organization and scape element of people who lived in Korea. In the hanok, people want to be live not only in human environment and traditional culture, but also modem urban housing as a high density. This article deals as follows: First, Hanok as urban housing would be composed in a housing lot, linear type layout, devide building, and cluster type. Second, Housing unit and configuration of Multi family housing can be used single story, second story, second story + single story, multi story and Hanok roofing. Thirds, structure of the building are traditional wooden, combined one of steel and wood or concrete and wood, and the building system in exterior and interior can be seperated into another system. Forth, Image of multi story Hanok A last, consistency of Hanok is not a repeat of an origin but application and creative aptitude of the origin, and multi family housing application of Hanok can be a trial creative.

In line with the recent public concern on the environmental issues in building industry, there has been a rise in demand for a healthy, sustainable housing environment in South Korea. In order to achieve a healthy environment in residential buildings, considerable efforts have been made in a wide range of sectors. Among others, the development of the certification schemes to promote environment-friendly planning and building construction is remarkable. In urban South Korea, recently built houses tend to be significantly high-rise, high-density buildings. Global warming has brought about drastic climate change and continued to increase the average annual temperature year by year. These changes should be well reflected on the government's implementation of the building environmental assessment system. For guidance, therefore, this study looks to the case of Hong Kong which is well known for high-density housing development and subtropical climate conditions. It compares the features of the green building certification schemes for newly developed multifamily housing in two regions, namely HK-BEAM in Hong Kong and G-SEED in South Korea. Based on the findings, it argues that the G-SEED implementor should have expanded roles in providing training programs and follow-up services in collaboration with the certification authorities. It is also argued that G-SEED professionals should be involved in the early stages of design processes, and training programs and licence systems to produce green building professionals should be developed. Finally, it points out that the assessment indicators should be more detailed and diversified.

The purpose of this study is to examine the changes of housing characteristics between dwellings occupied by two and more households and one household occupying dwellings over 10 years using the Population and Housing Censuses in 1985, 1990, and 1995. One dwelling for each household, referred to the ratio of the number of dwellings to the number of households, has been one of the most important housing goals in Korea. The results indicated that the ratio of dwellings occupied by one household as well as that of households occupying one dwelling by oneself have been increased since 1985. However, the number of dwellings occupied by two and more households have been decreased but the number of households who share one dwelling with other households have never been decreased. One dwelling for each household has been mainly increased by the multifamily attached dwellers in urban residences. Single-family dettached dwellings in the urban area are the most often shared with other households. Housing policymakers should consider not only the rapidly increasing single households but also renters shared one dwelling with others mostly homeowners of single-family dettached dwellings.

Purpose: Urban heat island and Heat wave raise urban temperature and create damage of human life. Growing up as quantitative supply to solve shortage of housing, Urban residential area in Korea have a low rate of nature surface and heavily population makes temperature rise. Most houses in the declined residential area are multi-family rental housing and have many factors congesting housing environment such as narrow in-between space, outdoor staircases, walls and semi-basement floor, which make thermal environment getting worse. Most of the residents in this area are small tenants vulnerable to climate change adaptation, This damage is expected to be even greater. This study focus on multiple dwelling in urban residential area prone to temperature rise and draw temperature adaption method that can apply to multiple dwelling.

Pilotis are support columns that lift a building above the ground. Thus, they can elevate the lowest floor to the secondfloor level and, in Korea, are used to leav a parking area below multifamily housing. However, if there is a fire in the piloti area, the cars and main entrance door are wrapped in flames. Due to the inflammability of the materials, the combustion of the cars and insulation at the ceiling of the pilotis, having a high heat release rate, can quickly destroy the front entrance of the building and spread heat, flames and a poisonous gas to the stairs and elevator pit. Therefore, the fire can quickly spread to the whole building, putting the lives of the residents in danger. This study was an in-depth accidental case study of the "Uijeongbu Fire Accident" that killed 5 residents and injured 139 others. The study identified the relationships between the fire at the piloti structure of multifamily housing and the vulnerability of this structure and its inherent weaknesses.

In Korea, most of the historic city became a deteriorated area with low-rise settlement. It is revaluated as a s great potential in spite of slum clearance and redevelopment for a long while after 1970s. A great achievement for low rise multi family housing, in spite of these social change, is not easy to find the cases and social commonness. In the view points, this article deals a ideal model in historic areas, and the model should be get the understanding from the people, because acceptance from people is the beginning for making historic housing areas. The facade model for evaluation prepared as three types, and responses for the models processed by AHP(Analysis Hierarchy Process).

The purpose of this study was to explore housing characteristics of young single- or two-person households in the U.S. metropolitan urban areas and determinants of their housing cost burden. Total 764 single-person households, 744 two-person households and 424 households with three or more persons were selected from the 2011 American Housing Survey public-use microdata for the study based on specific sampling criteria. The major findings are as follows: (1) In comparisons with larger households, single- or two-person households were characterized to be headed by younger householders, to have less income, and to have a greater proportion of households living in central cities of metropolitan areas, renting housing units, living in smaller size units or multifamily structures; (3) housing cost of single- or two-person households were significantly less than a larger households while housing costs per unit square footage (SQFT) of single- or two-person households was significantly greater; (4) regardless of the household size, there are many household headed by young college graduates paying too much of their income for housing, and single-person households were found to have the greatest housing cost burden; and (5) a linear combination of low-income status, monthly housing costs per unit SQFT, annual household income, and unit SQFT per person was found to be most efficient to predict single- or two-person households with housing cost burden.

This study is to derive a project model based on potential demand for Korean-style houses, focusing on new town detached housing sites that LH supplies and to test validity of the derived model and to present the direction and supply methods of the projects. The existing high-class new town Korean-style housing developments that have been considered were found to have little business value due to problems in choice of location and discordance of demand, so 6 types of projects were established through the methods of changes in planned scale, combined use, and subdivision of plot of land based on the results of survey. The type that has the highest business value among the project models was block-type multifamily houses, and this can be interpreted as the increase in total construction area leading to increase inrevenues of allotment sales due to economies of scale. The feasibility of mass housing model in which small-scale Korean-style houses are combined with amenities was found to be high, and if the same project conditions as those of the block-type multifamily houses are applied, the business value of the Korean-style tenement houses was found to be high. Besides, the high-class housing models within block-type detached housing areas are typical projects that the private sector generally promotes, and the construction cost was found to be most expensive with 910 million won per house. In order to enhance the business value of the Korean-style housing development, collectivization such as choice of location, diversification of demand classes, optimization of house sizes, and combination of uses is needed. And in order to adopt Korean-style houses in the detached housing sites, the adjustments and division of the existing planned plots are needed, and the strategies to cope with new demand through supplying Korean-style housing types of sites can be suggested. Also breaking away from the existing uniform residential development methods, the development method through supplying original land that is natural land not yet developed besides basic infrastructures (main roads and water and sewage) can be considered, and as the construction of more than 1~2 stories building is impossible due to the structure of Korean-style house roof and furniture. So it can be suggested that original land in the form of hilly land is considered to be most suitable to large-scale development projects.
