Purpose: The purpose of this study is to analyze the energy saving and cost benefit analysis of the Low-income Energy Efficiency Treatment Program supported by KOREF(Korea Energy Foundation). This program was launched in 2007 and performs building energy retrofit for the low-income and energy poverty houses. Method: Energy simulation and cost benefit analysis were accomplished for the low-income detached houses. The structure of detached house was a lot og block structure, wood frame (single glass) and concrete roof. Baseline model of the low-income detached houses was proposed. Result: Annual heating energy consumptions were decreased by about 3.2% with the window system replacement(Case 1), 9.3% with reinforcement of insulation(Case2), and 12.5% with both(Case 3) compared to those of baseline model. The construction cost will be recouped within 5 years for the Case 1, 3 years for the Case 2, and 3 years for the Case 3. Case 3 was the most cost beneficient construction method in the analyzed cases in this study.

With the government's support using new and renewable energy, photovoltaic equipment has been rapidly supplied. However, compared to supply rate, maintenance has not supported enough and relevant research has not much conducted. Even though large power plant facilities have been maintained well, small equipment for detached houses has been rarely maintained. Therefore, the purpose of this study is to analyze maintenance effectiveness of photovoltaic equipment for detached houses. It was analyzed that photovoltaic equipments were merely maintained. What is the most important in maintenance effectiveness is increase of power generation. It was estimated that if photovoltaic equipment for detached houses is maintained well, power generation increases by 6.5% at least. That produces the same effect as the additional supply of photovoltaic equipment to 9,700 households. As a result, it is necessary to maximize the effectiveness of the government's budget investment through well maintenance of photovoltaic equipments.

By 2019, Korea is expected to be an aged society, age group of 65 and older being over $14\%$ of the total population, considering their rapid increase today. Also the phenomenon of population structure are accelerated by a low birth rate and long life span. This study was intended to find out the inconvenient details in houses pointed out by the elderly. This survey was taken by trained interviewers from the people of ages 65 and older living in Daejeon city. Statistical analysis was implemented from 583 appropriate data out of 624 questionnaires using (SPSS PC+ 10.0). The results were as follows. The elderly were put to inconvenience noises in room, old facility in living room and outmoded facility in kitchen and bathroom in detached house. And they were put to inconvenience the size of room, living room and bathroom and old-fashioned facility in kitchen in apartment. The stairway and bathroom in detached house and balcony, elevator and bathroom in apartment were pointed out dangerous spaces in house.

There are many research Papers and experiments indicating that the geomagnetic field affects the people and living organism. People grow up and build up most of their character through living in dwelling space and have relax and refresh at home. Creating healthy dwelling space is being considered very important in architectural planning and design for providing comfortable living environment and improving quality of life. Therefore. it is necessary to investigate the geomagnetic field and people's response in living space. In this study the vertical component(Z value) of geomagnetic field in detached houses was measured, evaluated by related evaluation criteria, compared with interview survey.

The purpose of this study is to investigate the characteristics of the floor plan of single detached houses in Canada. A quantitative & qualitative analysis method of th 260 house plan was used in this study. The followings were found out from this analysis : 1) There were the differences of the lay-out and the number of public spaces between a small type and a big type. 2) There were the differences of the equipment and the number of bathroom between a small type and a big type. 3) The most work center type of kitchen was 'ㄴ+ㅁ' type(33%). 4) The most type of floor plan was that one with attached garage(87%) and center entry(99%). 5) Almost floor plans having 3 or 4 bed rooms even though medium II and large size plans which is to show that the basic needs of family life rely on the omnifarious public spaces.

The purpose of this study was to analyze the changes of floor plans in the entry and transfer spaces of single detached houses. The sample size was 185 households in Chungju, Jechon and Wonju Which are small cities in the central region of Korea. The results of the study are as follows: Firstly, the approach and transfer spaces show various changes and those are important factors which symbolize the housing plane typology transformations of the research areas. Secondly, the approach direction to the indoor space was more adopted a front approach in 1960's and 1970's, it is a side approach in 1980's, and a back side approach in 1990's. Thirdly, as the stage of the transfer space increased, the detached house planes have been changing to the direction, the depth of space comes to be deep, spatial function to be fixed, and privacy of bed rooms to be increased.

The spaces have a variety of sizes dependent upon their function and significance as well as their geometric shape. An architect Adolf Loos (1870-1933) had incorporated a correlation between the unconstrained formation of space into design. He had noticeably revealed the features of space that are unconstrained and mutually related with each other, for the space compositions among modern architects. This study is about to analyze the feature of space structure for houses of Adolf Loos through Space syntax which is the quantitative space analyzing method for the subject of his detached houses. These houses were emphasized for functional aspects of space without unnecessary decorations. Le Corbusier's Villa Savoye was analysed along with it to review a comparative point of view of his house's characteristic. Based on this, the features of the spatial structure of Loos' house were examined in conjunction with his views space as essence. A J-Graph and VGA for Adolf Loos' detached house revealed the structure's spatial characteristics in which the interior space is located deeply removed from exterior yet it is integrated as a whole. Also, it revealed that the experiments of the various spatial structures shown in Adolf Loos' detached house and European rationalist architects like Le Corbusier affected each other at the same time.

This paper examines the changes in housing characteristics occupied by two or more households from 1995-2005, as a replicated follow-up study done by the previous decade of 1985-1995. The data analyzed were based on the Population and Housing Census in 1995, 2000, and 2005 by the Korean National Statistical Office. Results showed decreasing trends in the percentages of housing units occupied by multi-households and of households sharing a housing unit, while the average number of households for a shared housing unit was increasing. Detached dwellings in dongs (neighborhood) including ordinarily single-family detached ones, mainly multi-family houses, were the most often shared with other households even in the trend of the decreasing number of the detached housing. Further research is suggested to focus on housing circumstances of households sharing a detached dwelling in Dongs by the type of detached dwellings.

Energy poverty has been defined as low-income households who paid energy cost more than 10% of their ordinary income. Therefore, there are various subsidy programs focused on house remodeling for low-income households and one of them is the Home Energy Efficiency Assistance Program which have done by Korea Energy Foundation since 2007. The aim of the program is to improve the thermal performance of dilapidated dwellings and analyzed the detached house for the low-income households to develop the building typology. The database contained approximately 3,061 households which was obtained from the program in 2013 and the results of the study were like this; 1) For the shape of residential houses, the number of rectangular shaped building was higher than non-rectangular shaped ones. 2) For the orientation of buildings, the south layout of the detached housing was dominant to gain heating energy into buildings. 3) For the floor area, the average floor area was $44.2m^2$, although its size varied wide variations, which range from $6.3m^2$ to $107.1m^2$. 4) For the windows and doors, the south-facing window was larger than the other side. Finally it would be possible to determine the characteristics of residential houses for low-income families. A future study could establish typology of low-income housing that it would estimate the performance of each model building before and after the retrofit to improve the energy performance.

The numbers of the elderly who suffer Empty Nest Syndrome have been accelerated as an aging population has increased vastly and nuclear families have been a dominating family type in modern Korean society. To make the elderly get out of this phenomenon and live actively, the scheme of converting their existing houses into shared houses was set as a hypothetical solution in this study, and finding out the responses of the elderly who owns their own houses is the purpose of the study. A small workshop panel method was used and the elderly aged 55 years upwards took part and they own a detached house that is relatively large for the elderly or the elderly couple to live alone. The workshop was consisted of 3 stages: 1. a survey 2. an interview 3. a site visit. Through this, problems that the elderly have been experiencing within their houses were looked into and the responses of the elderly on converting their houses to shared houses by introducing developed schematic plans. As a result, positive responses from the house owners were carried out based on the fact that subsidies from the government on house renovation and tenants matching programs are supported. Shared houses could provide home owners economical support with rents and help them to feel less lonely. This is one way of supporting the elderly to live and age actively in their later lives. Therefore, this idea should be established in connection with preparing aging, aged, and super-aged society.
