Recently, Indoor air quality (IAQ) is one of the most important problem in our daily life of modern societies. Mechanical ventilation system is being recommended as an effective method to improve IAQ in apartment houses. And then, in Korea, building industry should install ventilation system in apartment house by the building construction code. In this study, to improve IAQ caused by microbial and chemical contaminant such as bacteria and TVOC, three types of mechanical ventilation system of apartment house including HRV were simulated by multizone modeling. Simulation results suggest an appropriate and economical renovation method of apartment house ventilation system for reducing indoor air contamination.

The renewable energy system and the real-time pricing can provide the significant economic advantage for end-user of residential house. However, according to recent studies, high initial cost of renewable energy system such as photovoltaic (PV) system and lack of suitable load control methods adjusting electric power consumption in response to time-varying price are regarded as the major obstruction for introduction of renewable energy system and real-time pricing in residental household. In this paper, we propose automated optimal load control strategy which aim to achieve not only minimizing the electricity cost but also the increase in the utilization rates of PV generation power of residential PV house in real-time pricing environment. Simulation results show that our proposed optimal load control strategy leads to significant reduction in the electricity costs and increase in the utilization rates of power generated by PV system in comparison with the conventional PV house. Therefore, the proposed optimal load control strategy can provide more economic benefit to end-user.

The number of share houses has increased in Korea, and social recognition of this type of housing is also growing. In order to review current conditions and housing systems for share houses, an analysis of rooming house, a type of share house that is built overseas, was carried out. This study focused on studying rooming houses of Canada. Residents occupy in rooms and share common spaces with other tenants in rooming houses. The purpose of this research is to study planning guidelines, systems, operation management of rooming houses and the process and role of public and citizen participation. Based on characteristics of planning guidelines and operation management for rooming houses, implications which can be used for setting institutional and planning foundations for share houses in Korea have been presented through this research.

본 논문은 태양광을 이용하여 에너지를 발전하여 생성되는 전력으로 각종 센서 및 환경 모니터링이 가능하도록 계통 독립형 전력을 공급한다. 생산된 잉여 전력은 리튬 배터리에 저장시켜 태양광이 없는 환경에서도 컨테이너 하우스가 원활한 구동이 가능하도록 설계하였다. 긴 장마나 폭설로 인하여 태양광 생성이 어려우면 디젤발전으로 시스템이 멈추지 않고 구동할 수 있도록 하였다. 태양광 및 전력 관리를 위해 BMS(Battery Management System)를 구축하여 태양광 방/충전 및 사용량을 모니터링한다. 각종 센싱 데이터를 자동으로 기록하고 전송되며, 컴퓨터 및 스마트폰 앱을 통해 무선 모니터링이 가능하도록 설계하였다. 본 연구에서 제안하는 컨테이너 하우스는 계통 전원이 없는 오지, 공원, 행사장, 공사현장 등에서 최적의 에너지 운영을 수행함으로써 효율적인 에너지 관리가 가능하다.

There are approximately 1.06 million vacant homes in Korea, accounting for 6% of all housing, and approximately 98 thousand vacant homes are in Gyeongsangnam-do, taking up 8.7% of the housing in the province. In particular, the number of abandoned house in Gyeongsangnam-do is rapidly increasing from 6.7% in 2010 to 8.7% in 2015. This study examined the current state of abandoned house in Gyeongsangnam-do according to the characteristics of cities and rural areas, causes for vacancies, and demand for use of such abandoned house. The study areas were selected based on case studies in Korea and overseas, and a survey was conducted among residents in the selected areas. The survey was on awareness of abandoned house in the neighborhood, causes for vacancies, awareness of owners, the influence of the abandoned house, plans to deal with abandoned house, and plans to utilize abandoned house. The results showed that most residents were aware of abandoned house, especially the ones in rural areas, who had detailed perceptions about abandoned house nearby such as when the homes became empty and whether there are owners of the homes. As for the influence of abandoned house on the surrounding environment, both rural areas and cities responded that abandoned house mostly spoil the beauty of the neighborhood, followed by psychological anxiety such as fear of crimes. Regarding plans to utilize abandoned house nearby, at least half of the residents wanted to use them as rental housing after repairing them. A survey on the actual condition must be conducted at the provincial level in order to establish an integrated system to manage abandoned house in Gyeongsangnam-do. Moreover, it is necessary to come up with application measures according to categories and standards to classify the state of abandoned house in order to use them as resources for community regeneration.

Cause of struggling to escape from dependency of fossil fuels, the fuel cell and the Plug-in Hybrid Electric Vehicle (PHEV) draw attention in the all of the world. Especially, the Polymer Electrolyte Membrane Fuel Cell (PEMFC) systems have been anticipated for next generation's energy supplying system, and we can predict the PHEV will enlarge the market share in the next few years to reduce not only the air pollution in the metropolis but the fuel-expenses of commuters. This paper presents simulation results about the strategy of smart charging system for PHEV in the residential house which has 1 kW PEMFC cogeneration system. The smart charging system has a function of recommending the best time to charge the battery of PHEV by the lowest energy cost. The simulated energy cost for charging the battery based on the electricity demand data pattern in the house. The house which floor area is $132\;m^2$ (40 pyeong.). In these conditions, the annual gasoline, electricity, and total energy cost to fuel the PHEV versus Conventional Vehicle (CV) have been simulated in terms of cars' average life span in Korea.

This paper is a part of "The Study of the Traditionla Korean Ethnic Farmhousing in Yanbian, China" The purpose of this study is to investigate the facilities and equipments of the traditional farmhouse in the villages of Lungching China. The data is collected from 124 households in the villages based on the survey conducted using questionnaire and photograph. The major findings are: 1) The people in farmhouse use wood as a fuel for cooking and the method of cooking is traditional style using their iron pots. 2) Heating system of the house is ondol type of heating using. wood which is also traditional type. This means that the floor heating of the house and cooking food can be carried out simultaneously. 3) Even though pump system and running water system are the two kinds of water supply that are available in the villages, majority of people use pump system. Many houses have no drainage facilities but few houses have got bad drainage system. 4) From the planning stage of the farm house facilities and equipments for ventilation is not considered and hence it is not provided in most of the houses. 5) Farmhouses are oriented to the south and the windows and the doors are covered either with viny1 or cloth during winter time effecting the lighting system of the house. 6)Many of the houses use incandescent lights. But the switchs and the electric Outlets are short in number. 7) Sanitation facilities are worst equipped compared to other facilities present in Lungching villages of China. of China.

This study attempts to present a new interpretation of the Jeju province Waga, authorized as Jeju province Folklore, in the context of lifestyles of residents distinctive in the Jungji, Chatbang, and Gopang system. Study results uncovered that (1) only one Jungji, a traditional house kitchen, exists in one house boundary, in the form of detached building in the 4 units of Gaok (K-2 Gaok, K-3 Gaok, C-1 Gaok, and C-2 Gaok) (2) Chatbang had multifaced-functions; as a place for diet for mistress and children, a place for preparing meals for a mister who diet in the room, and as an auxiliary meal-preparation facility in time of domestic celebration day. (3) Gopang was mostly a place for grain storage, and K-3 Gaok has one unit, K-1 Gaok, C-1 Gaok, and C-2 Gaok had 2 units, and K-2 Gaok and H Gaok had 3 untis of Gopang. (4) Jungji and Chatbang were correlated for meal preparation and diet while activity-line of flow was divided each other. (5) Jungji and Gopang were located at the opposite edges of of each house, revealing no consideration of indoor activities. (6) The ratios of space of Jungji, Chatbang and Gopang out of the whole house space were, average 23% in the case of Jungji located in the inner house, and average 37% in the case of Jingji located in the detached building, average 14% larger in the case of detached Jungji system.
