Purpose: In this study, we evaluate the annual energy performance of the detached house which was designed with the aim of zero energy. Method: The experimental house which was constructed in Gonju Chungnam in 2013, is the single family detached house of light weight wood frame with $100m^2$ of heating area. Thermal transmittance of roof (by ISO 10211) and building external walls are designed as $0.10W/m^2K$ and $0.14W/m^2$ respectively and low-e coating vacuum window glazing with PVC frame was installed. Also grid connected PV system and natural-circulation solar water heater was applied and 6kWp capacity of photovoltaic module was installed in pitched roof and $5m^2$ of solar collector in vertical wall facing the south. We analyzed the 2014 annual data of the detached house in which residents were actually living, measured though web-based remote monitoring system. Result: First, as a result, total annual energy consumption and energy production (PV generation and solar hot water) are 7,919kWh and 7,689kWh respectively and the rate of energy independence is 97.1% which is almost close to the zero energy. Second, plug load and hot water of energy consumption by category showed the highest numbers each with 33% and 31%, with following space heating 24%, electric cooker 8%, lighting 3% in order. Hot water supply is relatively higher than space heating because high insulation makes it decreased.

In this study, we made a survey of the degree of satisfaction and performance of daily life activities on independent elderly households in the detached house. The purpose of this study is to suggest basic data for elderly housing design to be considered elder's characteristics. A survey carried out for 110 respondents with face to face interview visiting each house between May and June, 1999 with modified and drawn questionnaire from analysis of preparatory investigation data. The questionnaire was composed of the general characteristics of respondents, general characteristics of housing, residents' satisfaction with the use of housing space, performance degree of the elder's daily activities. To analyze the data of 106 cases, frequency, percentage, mean, standard deviations, one-way ANOVA, reliability analysis and Scheffe test were used by running SPSSWIN program. The results on the housing satisfaction and performance of activities in daily life of elderly in the detached house were as follows.: In this survey, the elderly had high value in satisfaction with the size of current house as the mean 3.14 points, but they were dissatisfied with the rising of house as the mean 2.82 points. The satisfaction with living room space was the highest but the satisfaction with toilet space was lower than others. Among the activities of daily life in housing space, housing related activity was the hardest to perform as the mean of 3.15 points. In consequence, consideration on and interest in the planning of residential spaces are needed so that the elderly can perform the action of housing life effectively and efficiently.

Ground-coupled heat pump(GCHP) systems have been shown to be an environmentally-friendly, efficient alternative to traditional cooling and heating systems in both residential and commercial applications. Although some work related to performance evaluation of GCHP systems for commercial buildings has been done, relatively little has been reported on the residential applications. The aim of this study is to evaluate the cooling and heating performances of a vertical GCHP system applied to an artificial detached house($117\;m^2$) in Seoul. For this purpose, a typical design procedure was involved with a combination of design parameters such as building loads, heat pump capacity, borehole diameter, and ground thermal properties, etc. The cooling and heating performance simulation of the system was conducted with different prediction times of 8760 hours and 240 months. The performance characteristics including seasonal system COP, average annual power consumption, and temperature variations related to ground heat exchanger were calculated and compared.

This study explored ways of changing a detached house which has older residents to a universal design home. This study investigated the residential conditions based on the universal design features and the need of universal design for aging in place. For this study, 153 residents who were living in single detached houses in Columbia, MO, were surveyed using written questionnaires and interviews. Primary findings of residential conditions were showed according to each spaces such as entrance, interior hallway, master bedroom, bathroom and kitchen. The major results are as follows: 1)It was confirmed that major spaces for daily living such as a bedroom, bathroom, kitchen and laundry facilities needed to be on the ground floor. 2)The most dangerous spaces in house were stairs to the upper or lower floors and the bathroom, 3)The need for modification based on universal design were high in order to facilitate aging in place. 4) Finally, elderly people in their seventies had especially strong needs through modification compared to the elderly people in their sixties who had plans to relocate.

The purpose of this study was to analyze land use plans of 61 residential complexes and identify the factors that caused the variation of urban parks and green space ratio depending on the land ownership processing method. The ratio of urban parks and green space of expropriation districts was higher than that of replotting districts. Within the same city and country as well as other regions, the parks and green space ratio of land expropriation districts increased higher than 7% compared to that of replotting districts. The variation of urban parks and green space ratio was mainly related to the ratio of road. Small housing complexes such as detached house and quasi-residential sites resulted to expand space for road construction, thus, the areas of urban parks or green space came to reduce. The average urban parks and green space ratio in the urban development by the expropriation method and replotting method are 24.5% and 16.8% respectively. In order to prevent the reduction of urban parks and green space ratio according to the preference of detached house sites or quasi-residential sites in development zones, it is necessary to make systematic adjustment such as adjusting the urban parks and green space ratio securing standard.

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.

Recently, the field of construction is putting a variety of effort into reducing CO2, since global warming is being accelerated due to climate changes and the increase of greenhouse gas. For reduction of CO2 in the field of construction, it is required to make plans to cut down heating energy of buildings and especially, it is urgently needed to cut down energy of residential buildings in rural area where occupies the majority of consumption of petroleum-based energy sources. Therefore, this research compared and analyzed the actual energy consumption, by evaluating energy performance of a detached house applying passive house design components for reduction of energy. As the result, energy consumption showed remarkable differences, according to the operation of a heat recovery ventilation unit which is one of passive house design components, and building energy consumption displayed remarkable differences, too, depending on the difference of airtightness performance during building energy simulation conducted in process of design. Based on these results, the importance of airtightness performance of passive house was verified. The result of the actual measurement of energy consumption demonstrated that LNG was most economical amongst several heat resources yielded, on the basis of LPG source energy consumption measured within a certain period of time, and it was followed by kerosene. LPG was analyzed to have a low economic efficiency, when used for heating.

Modernization of cities and housing in Malaysia is a reflection of the history of the establishment of colonial trading ports for worldwide maritime trade and exchange. In cosmopolitan cities, new housing typology appeared from the influence of various ethnic immigrants and with the fusion of traditional Malay housing characteristics. This study is to focus on classifying the housing typologies of Malaysia which were formed through the modernization process of cities. The typologies of modern housing in Malaysia can be classified into two categories. The first category is the 'transformation of traditional housing'. The representative typology of this group is the ubiquitous shophouse. The shophouse was originally brought in by the Chinese immigrants from the south coast of China and transformed into the Malaysian urbanscape. The other typology is a detached-house known as the bungalo, which was the housing style combining the Malay traditional timber house and European palazzo. The second category is the 'modern urban housing typology'. Modern urbanization after the independence from the British in 1957 required the maximum utilization of land. To accommodate new social and economic needs, the new typologies were developed in the form of medium-density terrace houses (row houses) and high-density apartment. In the suburban areas, the British terrace house was adopted and developed into unique Malaysian terrace house and semi-detached house based on the British system of land sub division. In premium area of the city, luxurious housing type in the form of high-end condominium is one of the popular housing for upper middle-class and high-class society.

Through the industrialization since 1960, Korean housing has been developed in a uniform way which is to demolish first and then construct from the scratch. In this process, detached houses and multi-family living detached houses have disappeared without being paid much attention. The detached houses with blood or non-blood related multi-family living situations are typically popular, and worthy enough to explore for professionals right and creative solutions to enhance their values. But many of the people suffered for the expenses and the absence of the idea to enhance their housing themselves. The purpose of this research is to clarify user's demands of developing an adaptable lifespan house and to try to find the solution about the expenses of self improvement. This study used a Small group workshop Panel Method. The workshop consisted of three stage, such as the awareness of their existing residence and lease status, the needs of the housing improvements and the demands of the adaptable house. This study is expected to serve as a fundamental data to promote discussion on reuse of existing residence building and to promote rental detached houses.
