The Solar Energy R&D Department of KIER under the auspice of the Korean government is pushing hard on the development of the passive solar technology with high priority for the expeditious widespread use of solar energy in Korea, since the past few years of experiences told us that the active solar technology is not yet ready for massive commercialization in Korea. KIER has completed the construction of the Solar Energy Research & Test Center in Seoul, which houses the major facilities for its all solar test programs. The Center was designed as a passive solar building with great emphasis on the energy conserving ideas. The Center is not only the largest passive building in Korea, but also the exhibit center for the effective demonstration of the passive heating and cooling technology to the Korean public. The Center was designed to satisfy the requirements based on the technical and economical criteria set by the KIER. Careful considerations, therefore, were given in depth in the following areas to meet the requirements. 1) Passive Heating Concepts The Center employed the combination of direct and indirect gain system. The shape of the Center is Balcomb House style, and it included a large built-in sunspace in front. A partition, consists of transparent and translucent glazings, separates the sunspace and the living space. Since most activities in the Center occur during the day time, direct utilization of the solar energy by the living spaces was emphasized with the limited energy storage capacity. 2) Passive Cooling Concepts(for Summer) Natural ventilation concept was utilized throughout the building. In the direct gain portion of the system, the front glazing can be openable during the cooling season. Natural convection scheme was also applied to the front sunspace for the Summer cooling. Reflective surfaces and curtains were utilized wherever needed. 3) Auxiliary Heat ing and Cooling System As an auxiliary cooling system, mechanical means(forced convection system) were adopted. Therefore forced air heating system was also used to match the duct work requirements of the auxiliary cool ing system. 4) Effect ive Insulation & Others These included the double glazed windows, the double entry doors, the night glazing insulation, the front glazing-frame insulation as well as the building skin insulation. All locally available construction materials were used, and natural lightings were provided as much as possible. The expected annual energy savings (compared to the non-insulated conventional building)of the Center was estimated to be about 80%, which accounts for both the energy conservation and the solar energy source. The Center is being instumented for the actual performance tests. The experimental results of the simplified tests are discussed in this paper.

Considering that rural village had evolved through a long-sustained effort of harmnization with nature, there should be the wisdom not only to reflect the level of rural resident's housing demand, but also to conserve the traditional characteristics of high-valuation in the modern rural housing. In Korea , standard design proposals of rural houses had been made public three times ; in 1972 , 1984 and 1995. so , firstly, this study analysed the inner-space layouts of design proposals mentioned above, from which changes and problems in the past housing design were derived. And also, through, the positive acceptance of residents' opinion living inthe houses built by standard design proposals in 1970 ~1980's, improved design principles and an alternative model were proposed , finally. The inner-space structed of standard design proposals in 1970s was originated from small-scaled and low-priced one, basically under the " open system". In 1980s, the basic design principle changed to the 'closed system' in which the living room being the focus of indoor family life, and , in 1990s, progressively, therural housing developed to the high qualified type by the spatial enlargement and with increased equipements. However, this structural change of rural house brought about the problem of functional separatioon between farming and daily living activities. In details, limited spaces of multipurpose spaces and sanitary facility would be mentioned as problems for improvement. conclusively in this study, newoly arranged "open system" was recommended , as a basic design principle for theinner space structure formation of rural house, which easily links the constituent inner-house spaces to outer one. Based on this principle, the detailed design criterial was proposed as follows ; 1. The living room be directly linked to the front-yard and centrally placed, the addtional space of which could be secured for the special family events by the flexibleuse of its adjacent room or by the housing of male quarters(separated from main building quarter). 2. The kitchen also be directly linked to side-yard and to livng room , for the convenience of farming activities and the shortening of path flow housewife. 3. The expanded toilet-and-bathroom be placed in the directly connected left-hand side to the living room and also be allowed access through multipurpose spaces to out door. 4. The multipurpose spaces be directly connected to the kitchen and the toilet and-bathroom , of which function would be for undressing of working clothes, quickwashing and ordinary working.nd ordinary working.

The objective of this study is to find out the recent trends of hanok design based on 58 hanoks appeared in architecture magazines in the last 10 years. The cases are analyzed in terms of location, size, building form, spatial organization, material, roof form, and the ceiling form of living room. The consequences of this study is as follows; Most of the recent hanoks are built in rural area (91.4%), which shows the hanok is not accepted as an urban house type. Hanoks tend to be built in 2 stories whose 2nd floor is smaller than the 1st floor. (34.5%) The preferred size is total floor area of $99.2{\sim}165.2m^2$ (62.0%), 3 rooms (46.6%) with a traditional ondol room (60.3%). The buildings with ㄱ-shape (43.1%) and linear-shape (27.6%) are preferred, and the compact plan type similar with apartment house appears (13.8%). In the roof design that greatly influences the appearance of building, the traditional design factors such as half-hipped roof (55.2%), double eaves (27.6%), and eaves curve tend to be sustained. In terms of spatial organization, most of recent hanoks have double-layed plan (74.2%). The living room mostly has separately defined space. (82.8%) The indoor and outdoor tend to be connected by a narrow wooden veranda (39.7%), while some cases don't have any wooden floor space (48.3%). The entrance is adopted as an important spatial element in front part of building (75.9%), and it influences the appearance of building. The living room, the counterpart of the wooden floor hall in traditional hanok, and kitchen tend to be interiorized. In terms of material, the cement roof tile and red clay brick are preferred. Consequently, the walls of recent hanoks have the image of brick structure rather than the wooden frame structure of traditonal hanok.

This study is intended to derive the adaptive reuse techniques through the history and aspects of new construction, extension, repair, and other works, limited to the deep and narrow lots facing Seongan-gil and Nammun-gil in Nammun-ro 2 ga of Cheongju, the historic urban area. The results are as follows. 1) In the case of newly built reinforced concrete buildings, the central part of the top floor of the residence or all floors are opened to the open space(void) to facilitate lighting and ventilation. This is developed as a convection phenomenon due to the temperature difference from the slits between buildings, which affects the entire air flow of the block. 2) The buildings of extension and repair are composed of two-story masonry or steel frame, both the front store facing the road and the house on the back, but it looks like one because it is in contact with each other. If only a small gap between the front and rear buildings is restored to an external space or a space equipped with sun light, a small breath can be provided in lighting and ventilation. 3) The existing two-story wooden stores and houses have lost their external space due to repairs. With minimal intervention to restore the small courtyard, slits, and space under the eaves, it will not only improve lighting and ventilation, but also create a unique appearance as a segment of the elongated store.

The recent trends of high-density and high-rise in apartment housing have caused the problems of decrease in ventilation rates and increase of indoor pollutant contaminants. SHS(Sick House Syndrome) has now become a major issue and threats the health of residents. To solve these indoor air problems, increase in ventilation rate is considered as one of the most efficient approach. Thus, the recent housing development is pursuing improvement in the site design and the layout of apartment building blocks to promote natural ventilation is now investigated as one of the fundamental solutions. This study was focused on the air flow characteristics of outdoor environment in an apartment complex to keep the pollutants out of the site. Age of air and pressure difference have been used as indices of the outdoor air quality. Four different types of apartment building layouts have been analyzed by CFD simulation. This study again selected a real apartment housing complex as a case study model. By analyzing the pressure differences between the front and rear of an apartment building block, the ventilation performance in each individual unit was evaluated, and its impact on ventilation performance is investigated by analyzing the stagnant air around the apartment building blocks. During this process, existing patterns of apartment housing layout have been evaluated, and the most appropriate site layout has been chosen to analyze the outdoor airflow patterns. Based on the analysis of airflow patterns of site layout, the possibilities of improving ventilation performance of an individual apartment housing is proposed.

Prevention of exhaust gas back flow becomes a great interest to shipyards and shipowners in large container carriers because exhaust gas pollutes cargoes, flows back into the deck house and the engine room area through fresh air intakes and fan rooms, gives harmful damages to the crew's health and also gives thermal damages to electric equipments on the navigation deck. The phenomena of exhaust gas back flow has been studied with the analysis of sea trial records and wind tunnel tests and the height of the exhaust gas pipe, the front area of the deck house, the inflow speed and the position of the radar mast platform has been confirmed as the principal factors of exhaust gas back flow phenomena. The simple empirical formula to estimate exhaust gas back flow phenomena and the design guidances of exhaust gas related structures on deck has been introduced. In future, parametric studies for the exhaust gas back flow factors will be carried out with the CFD analysis. The results of this study will be the guide for development of the prevention method of exhaust gas back flow phenomena for large container carriers.

Basic concept of this study is that architectural form as a material at present has meaning for the dweller's life on the past historical plane. Main method to recover history is ethnographic interview to dwellers. Secondary method is to analyze ancestors' writings, buildings in the background of the family photos, and past drawings and then to relate them with architectural form at present. Taxonomy is a starting point: general name of the building by outside researcher is quite different from it by inside dwellers. 'Haengrang-chae', servant quarter, has never been used for servants. Function of the haengrang went outside thatched houses at the front village. Firsthand observation or simple analyses as results of several precedent research are reexamined and criticized through this study. The mansion has moaning when we synthesize with the site location based on farming land and tenant farmer, and decline of the Kyongpo Lake. Territoriality of the mansion is reinterpreted to 'In-Out Structure' by Yin-Yang thinking, Dwellers extend buildings gradually to outside village, surrounding rear hills, the lake, DongHae Sea, and finally goes to imaginative Taoist heaven beyond real nature through the literary life. Confucius principle, known to govern upper class house at Yi Dynasty also affect general composition of the buildings: perpetuation of the family by ancestor worship, elder dominance and male dominance, fraternity love in the extended family, charity display by reception of guests, Taoist scholarly life harmonized with nature. However, the study of the particular life and usage of the dwellers reinforces or corrects general supposition of precedent researches. Unique shape of the house has been formed by convenience of the dwellers' life style, early modernized free thought over the rigid Confucius design principle, and female power in male dominant society.

This study is proposed to research the rural clothing, dietary and housing style of living in order to adapt a basis which is supposed to improve the quality of rural life. The sample in this research comes from Daehang 1 Li, Bubuk Myun, Miryang Gun, Kyungnam, and the results are as following; Generally rural housewives are unconcerned with fashion or its information, instead, they care for the casual wear which represents economic and active life style. Because of their financial problems, inpurchasing, they spend only a small money without plan. When they launder Clothes, they use washing bat and pannel which is easy to break fabrics, and they ineffectively use to dry it by hands twisting. The total food intake per person in a day is 1170.6gram, and all nutrients intakes except fat and calcium exceed the recommended dietary allowances. But 90.3% of the food intakes are plant food, and the average food items taken per day per househod is 11.9items which are not so various, which represents the shortage of the nutrient quality. Both the nutrition knowledge score and the food habit score are very low. Therefore, in order to enhance the quality of clothing and diet in rural life, they need to learn clothing and nutrition management for their enlightment. The most comprehensive type of farmhouse site plan take the shape of ㄱ and ㄴ, and for the most part main building is the floor plan which includes 3-4 spans in front of the change from the type of traditional house, throught the revised one, to the type of newly built house. In main building of the farmhouse, kitchen, Kunbang and Chakunbang are extended to their real space, and both utility and the bathroom are added to build, and Malu is transformed into the living space.

In an apartment house that is generally air-tight and well insulated, the combustion gas from cooking devices is the major source of air pollution in the kitchen. It spreads throughout the house affecting the overall Indoor all quality. In this study, the performance of the kitchen range hood which employs air induction and air curtain was investigated by numerical simulation. The results are compared with that of two other kitchen range hoods which are in general use. The two general types of range hoods considered in the present calculations are box and plate type range hoods. The former has a large capture space between the filter and suction duct, while the latter has little. It was found that the capture efficiency of the kitchen range hood with air induction and air curtain Is higher than that of the general types of range hoods by 20% approximately The reason may be because the air induction and the air curtain block the air stream escaping from the front and the side part of range hoods effectively and because an additional fan for air induction and air curtain increases suction flow rates.

Ikseon-Dong 166 is one of the traditional urban resident area developed during 1930's. The purpose of this research is to analyze the structural relationship between a conventional housing unit plans and modern block plans based on orthogonal geometry. To fully explore the selling point of the new urban development, the planner or real estate developer in private sector did not abandon or compromise the conventional house layouts, consists of single layer of rooms keeping the main room facing south. This study concludes the following factors connecting the urban and architectural plans. Oblong block plans following east-west direction did not allow the southern exposure of courtyard and main room, which was the absolute requirement for traditional house units, the longer side of block plan followed north-south direction as a result. Considering the possibility of rent, having entrance at the east or west side of individual site enables two separate household maintain their spatial privacy. In addition to the factors mentioned above, when the blocks are to be divided into individual addresses, north-south oblong block plans maintained the length to face the front road minimum while the southern exposure maximized. These factors explains why the private developers maintained their blocks elongated to north-south direction when the block plans laied out by public sectors which did not care that much of southern exposure show random orientation in the view point of solar exposure.
