Currently, the housing supply rate exceeds 100%, and the penetration rate continues to increase. This housing supply rate is changing from quantitative supply-oriented to improving the quality of the residential environment in housing service policies. Despite the increase in the housing supply rate, practical access to the vulnerable class is still difficult and there are many areas that are insufficient to use housing services when necessary. In addition, the demand for residential services is increasing due to the expansion of the scope of the vulnerable class. In order to compensate for these problems, facilities and joint occupancy that cannot guarantee independent living are mainly established, although a supply plan is established for the vulnerable by expanding policies and support projects. This paper proposes an IoT environment-based housing support system for vulnerable groups to support housing services for vulnerable groups. The proposal system improves the quality of the residential environment and provides service-oriented support services. Through the proposal system, appropriate social participation opportunities can be provided by improving the quality of life of the vulnerable and supporting a residential environment where independent living is possible.

In case of Korea, immovable property like location, land prise or investment value is more highly estimated than quality of life of residents for performance and value of apartment house, because of limited land area or high density of population. But the high level of life has recently caused the increasing demand in better life. As there is no cases to provide the house in bulk due to the housing market condition, it is necessary to evaluate performance and value of structure, disaster prevention safety, habitability, antiquated condition of building and equipment, maintenance condition and so on that has importantly influence on resident's life quality. So, this study aims to understand the actual condition of environmental performance for the present apartment by comparing the designated apartment, which is ready to have completed in Daegu, with the mixed use residential building, which gained the best grade for green building certification system. Also by analyzing and evaluating a right to enjoy sunshine, floor impact noise etc. and indoor air quality.

In case of residential fuel cell system, it is significant to stably supply heat and power to a house with high efficiency and low cost for the successful commercialization. In this paper, the control strategy analysis has been performed to minimize the total cost including capital and operating cost of the residential fuel cell system. The proposed analysis methodology is based on the simulator including the efficiency models as well as the cost data for fuel cell components. The load control strategy is the key factor to decide the system efficiency and thus the cost analysis is performed when the fuel cell system is operated for several different load control logics. Additionally, annual efficiency of the system based on the seasonal load data is calculated since system efficiency is changeable according to the electric and heat demand change. As a result, the hybrid load control combined electricity oriented control and heat oriented control has the most economical operation.

The purpose of this study was to develope a housing suitable for the Korean elderly by analyzing traditional minds on housing of the middle-aged. Data were collected by the questionnaire from 696 middle-aged in 40's and 50's living in Chinju area. Collected data were analyzed by using statistical methods of One-Way MANOVA, scheffe's test, and multiple regression analysis which were processed with SAS. Following are results. 1) Middle aged people had four main traditional factors in their minds: a propensity toward traditional indoor atmosphere, traditional housing space, traditional housing value and ceremony space & traditional life style. 2) Socio-demographically, a propensity toward traditional housing space and ceremony space & traditional life style were significantly different between sexes, but not by educational level and income. A propensity toward traditional indoor atmosphere and ceremony space & traditional life style were different between housing types. 3) However, there were a significant difference between variables such as sex, educational level, income and housing type in residential demands for the elderly life. 4) Sex, housing type, a propensity toward traditional housing space and traditional housing value influenced residential demands for the elderly life I indoor and outdoor environments, nearby facilities and available services all of which were minor items in the demand for the elderly life.

This study focuses on the regeneration of multi-dwelling residential estates located already in built-up areas. This study focuses on policy measures and surveys of remodeling and analyses the likelihood of remodeling and prospect of it. These major findings were diseased: First, people have changed their propensity about renewing their residences from reconstruction to remodeling. This would account for the likelihood of remodeling and its popularity. Second, unlike the stronger demand for remodeling, over half of people respond express that they are reluctant to pay the costs involved in renewing the public spaces of their apartment complexes. This argues that it would be necessary to review policy measures in other countries. Reducing financial burdens of those who are willing to remodel their residents and to trigger their participations. In addition, the costs should be saved from the outset of constructing new buildings. With the suggestions drawn in this study, the remodeling should be regarded as a considerable measure to renew the residential areas, especially where the area is already built-up and the development density is severely limited.

Energy efficiency and indoor air quality have become main issue to develop healthy and sustainable building in these days. As an effort to reduce the energy consumption in multi-residential building, many attempts as like passive design strategies and renewable energy as well as active control method are tried. However, underground parking lot in multi-residential building seldom adopt the sustainable strategies and only mechanical system is installed as usual. Moreover, the mechanical system installed in underground parking lot is rarely operated due to the electric demand for operation after completion. In this study, as an energy efficient measure, natural ventilation system using stack effect as a driving force for underground parking lot will be proposed and the performance of the suggested system will be analyzed by simulation method.

The government policies and initiatives to guarantee sustainable energy and clean environmental conditions contributed to the introduction of green technology electricity appliances in the market. This study sought to determine the physiological and socio-economics-demographic factors driving residential electricity consumers to use green technology electricity appliances, mainly solar PV, smart meter, electric vehicle, and battery storage technology. By understanding consumer intention, the investors of solar PV, battery storage, electric vehicle, and smart meter can estimate the demand and upscale the market for the corresponding products. For that purpose, the intention to use the solar PV, smart meter, electric vehicle, and battery storage function is developed by utilizing the combination of the theory of planned behavior, technology acceptance, and reasoning action. A reliable and valid structured online questionnaire and stepwise multiple regression are used to identify the possible factors that drive consumer behavior intention. The results show that the social influence, knowledge on RE, and perceived price significantly influence residential consumers' willingness to adopt the technologies offered. The findings of this study suggest that the involvement of NGOs, public figures, and citizens' cooperation are all necessary to spread information about the government's objectives and support Malaysia's present energy and environmental policies.

The aim of this study was to analyze differences in the perception of Gangwon-do residents using a satisfaction survey. The residents were found to be most satisfied with sectors such as parks/green spaces, landscape, and public order; however, they were least satisfied with transportation, culture, sports, medical services, and welfare facilities. Additionally, among all the items in the satisfaction survey, job satisfaction was the lowest. When comparing satisfaction trends observed in the city to those of the county, the overall satisfaction of the county was found to be slightly higher. This result could be attributed to young people being underrepresented in this survey in conjunction with the greater policy-level support for middle-aged people by from the government and Gangwon-do. Therefore, it would be worthwhile to create policies that primarily support young people and to also to create high-quality jobs with stable pay and employment prospects. This could minimize the outflow of youth and even encourage their inflow to similar small provincial cities. In Southern region and Seorak region of Gangwon-do, the satisfaction with gap between house price and region was low, which might be related to the increased demand for real estate throughout this area.

This paper analyzes Korean residential tenure choice for house which is the most important in Korean households' assets. Data used in the analysis is the data of Korean Labor and Income Panel Study for the period from 1998 to 2006 and with 2341 households. In this paper, a household chooses a housing tenure mode, either by renting or by owing house. We use a mixed-logit panel model as an estimation model to take into consideration household's heteroscedasticity of preference in tenure choice. It turns out that the heteroscedasticity is significant in households' tenure choice behavior, implying that Korean housing policy emphasizing supply side should consider the demand side.

As the properties of living space and objects change in the digital era, furniture is also expected to change. This study starts from the question of such inclination that the digital innovation drives territories among products into the ambiguous, then tries to trace the variation of meaning against the furniture. Based on this possibility these functions, this research aims, to find out the digital functions which is preferred to be integrated with the furniture for the users of the residential space and the interface design aspects, which are considered important. preliminary survey using university students was done to extract the possible digital functions for convergence. The respondents were married women in their 20s and 30s who filled out the surveys on the internet. As a result, the specific digital convergence functions for both living and kitchen space were Identified. As major important expects for them were found functionality and controllability. Thus furniture design will expand to a concept which designs a new way of life.
