Seoul has been watched at its symbolic image which is the capital of one nation. since then Joseon was established. So, most of study about Seoul placed too much emphasis on like next; urban organization, palace, government office and public establishment. On the other hand, it is lacking in study of the individual building, the residential district, the change of building-lot. This study is to make up a deficiency from study of Gaokdohyung(家屋圖形site and floor plan). Gaokdohyung(家屋圖形) is drawings of building lots & houses existed in Hanseongbu漢城府(modem Seoul). It is possessed in Jangseogak and all 24 sheets. It is merely 24sheets but has many urban information in that. Housing of number 116 expressed in Gaokdohyung are consist on the house of Sadaebu士天王(noble class) Joongin中人(middle class) Sangmin常民(commoner), Villa(Byeolseo別墅) and connecting stores etc. Houses in Gaokdohyung has characteristic that most building lot is very specious and owners are variety of social position. The study of Gaokdohyung will progress through analyzing diachronic change of individual building lot & house. In the event, results of this study will help to find out change of urban tissue & architecture. So, i intend to seek for entity of urban tissue and urban house in Joseon Period differ from now, and to study out those have been changed continuously forward now.

Increased evidences reveal that the global climate change adversely affect on the environment. Smart grid system is one of the ways to reduce greenhouse gas emissions in the electricity generation sector. Since 2013, Korea Electric Power Corporation (KEPCO) has installed smart grid station in KEPCO office buildings. The goal of this paper is two folds. One is to quantify the reduction in greenhouse gas emissions through smart grid stations installed in KEPCO office buildings as a part of pilot project. Among components of smart grid stations, this research focused on the photovoltaic power system (PV) and energy storage system (ESS). The other is to estimate the reduction in greenhouse gas emissions when PV is applied on individual houses. Results show that greenhouse gas emissions reduce 5.8~11.3% of the emissions generated through the electricity usage after PV is applied in KEPCO office buildings. The greenhouse gas emissions reduction from ESS is not apparent. When PV of 200~500 W is installed in individual houses, annual greenhouse gas emission reduction in 2016 is expected to be approximately $2.2{\sim}5.4million\;tCO_2-eq$, equivalent to 6~15% of greenhouse gas emissions through the electricity usage in the house hold sector. The saving of annual electricity cost in the individual house through PV of 200 W and 500 W is expected to be 47~179 thous and KRW and 123~451 thousand KRW, respectively. Results analyzed in this study show the environmental effect of the smart grid station. In addition, the results can be further used as guidance in implementing similar projects.

The number of modernized green houses have been increased to produce high quality and high-payoff farm products. The unit investment costs per pyeong($3.3058m^2$) for building a glass house was estimated at 449 thousand won. On the other hand, the unit prices for the PC house with iron frame and the vynil house with automatic control system were revealed 365 thousand won and 93 thousand won respectively. The main objective of the study was to identify the financial feasibility of the green house investment prevailed in rural area. At present, some farmers have selected the green house without any consideration of profitability of crops and accessiblity of their fanning practices and technology. For the soundness of green house cultivation and management, the indices of finacial efficiency for the modernized green houses were necessary. The decesion making criteria such as NPV(Net Present Value), IRR(Internal Rate of Return), B/C Ratio and Payback Period were analyzed for the individual high investment facilities considering the present farmer's technology and on-farm benefits and costs. The results of the feasibility analysis of green houses were as follows: 1. In case of 100% private burden of the investment costs, NPV revealed only positive value for the vinyl house with automatic system and IRR for the house was also estimated at more than 10% and B/C Ratio was amounted to more than 1.0. On the other hand, the other glass and PC houses showed negative NPV and unacceptable B/C ratio and IRR. 2. In case of the following terms and conditions as 50% Government subsidy, 20% loans and 30% farmers burden of the total investment cost, all the green houses showed acceptable IRR, B/C Ratio and NPV. 3. The financial feasibility of the glass house was acceptable in tomato cultivation rather than in cucumber cultivation. The payback periods of cucumber were represented as 8.9 years for glass house, 8.5 years for PC house and 4.1 years for vinyl house with automatic system respectively. In conclution, the glass and PC house cultivation of high value vegetables were only acceptable under the Goverment subsidy and loan systems from the view point of farmer's financial situations. On account of the unacceptable economic rate of return, the government subsidy and loan policy for glass house cultivation should be transfered to the vinyl and pc houses in the future.

This study was intended to suggest that new small-sized apartment houses should be designed and provided on the base of the concept of universal design. This is based on the diversity of each resident, that is, resident of not as a family, but as an individual. On the background of this, this study evaluated the small-sized apartment house in aspects of universal design. The walk-through and the residents' evaluation were carried out by using 60 items related to the principles of universal design. The 18 pyung apartment complex and housing unit in Jangyou new town area was evaluated. Also, 100 residents living in that apartment housing unit were asked to evaluate these 60 items by using 5 point Likert scale. The walk-through with measuring and taking pictures was carried out by researchers. In general, the apartment house was not met the fundamental elements of universal design. Thus, it was not appropriate for the disabled or the elderly to live in. Specially, the door width of bathroom and kitchen balcony was too narrow to pass through. Also, the floor of entrance and bathroom was not flat, so that the wheelchair user cannot enter by alone. The residents evaluated negatively many items related to design, such as shape, color, and material. Therefore, in order to provide the living environments for diverse residents such as the elderly, or the disabled to live together, the new small-sized apartment houses should be designed on the base of the principles of universal design.

The purpose of this study was to identify the influence of living factors on TVOC(Total Volatile Organic Compounds) concentrations and personal factors to reduce the Sick House Syndrome for newly-built apartments. The field measurements of TVOC concentrations were made totally 30 times(5 times per one subject house) in six apartment units in which residents recently moved. Those apartments authorized its business approval before May 2004, the Act of Indoor Air Quality Management for multi-use facilities. The Questionnaire surveys of residents' subjective responses on the Sick House Syndrome were carried out in 2nd measurement of each house. Respondents consisted of 20 residents living in the measured houses. The findings were as follows: The TVOC concentrations of the measured subject apartments ranged from about 1/10 of the recommended standard for multi-use facilities($400{\mu}g/m^3$) to up to 90 times as high as the standard. Since then, the Recommended Standard of Indoor Air Quality Management for newly-built apartment house was announced in December 2005. In accordance with this standard($2390{\mu}g/m^3$) it ranged from about 1/100 to up to 15 times as high as the standard. The subject house whose TVOC concentrations reduced below the recommendation standard in the shortest period had the largest amount of ventilation (all the windows were open for ventilation in the past three months) among all measured houses. The reason of another house whose TVOC concentrations were much higher than the rest was fronted with new furniture in the room. There turned out to be no apparent relations between the TVOC concentrations and the residents' individual responses of Sick House Syndrome. The responses were serious in those who stayed in their new houses for a long period or had disease like allergy. It's recommended that they should open all the windows for at least three months for ventilation in newly-built houses, and it would be better to avoid remodeling than needs be.

This study is about finding out characteristic of recognition individual housing in seaside of Donghae. To accomplish this purpose, we survey the 150 houses related to the landscape. Thus the major analysis is to take basic data, such as image(modern, western, traditional, etc) about exterior form of housing corresponding to the landscape. The result summarized as follows First, the elements for the characteristic of recognition were exterior material finish, exterior color, roof type, roof material finish, window size, roof slope, area of wall vs roof. Second, the image of traditional housing was very insufficient to plan landscape of housing with design elements. This research suggests that landscape housing of future is to be environmental landscape design and the proper design is to be various considering not only user's preference but also control of landscape.

The maintenance and improvement of housing become more important than quantitative supply. So this paper suggests the directions to solve the current issues of housing improvement policies. In 2015, the housing improvement for the low-income has been expanded with the revision of housing benefit policy. And each related government departments are steadily carrying out various housing improvement programs. Under the current improvement policies, individual houses are being repaired according to the criteria of the target selection. And the repair allowance of the housing benefit is limited to the ownership households except the rented. Hereafter, it has to considered the review of the detailed goal setting and application problems in housing improvement policy and to consider the extension to the rented households and the raise of the income criteria of targets. Also, it needs to carry out the improvement of several neighboring houses at the same time for synergy effect other than individual house, to change the selection way of repair contractors and to secure the quality and advancement of the improvement.

The use of district heating is expanding very rapidly in Korea. High population densities and the relatively cold winters make district heating an economically attractive option. About 8 percent of Korean houses are already using district heating and the government is seeking to aggressively expand this number. It has set a target of 15 percent of the residential heat market to be met by district heating in the year 2001. The main purpose of this paper is to analyze the consumption behavior of households using district heating. By pooling time-series and cross-sectional data for 12 apartment complexes in Seoul area, a single demand function is estimated and used to forecast the amounts of heat demanded by the individual households. The results shows that the level of consumption varies among households, depending on the non-economic factors such as the installation of individual metering equipment and the volume of apartment building. When individual metering equipment is installed, the level of annual heat consumption per household declines, on average, about 22.1 Mcal per square meters, which is equivalent to 834 won per square meter in terms of heating expenditures. In case that the apartment building was built in more than 6 stories, annual consumption level reduces additionally about 17.3 Mcal per square meters and, thus, save the expenditures by 649 Won per square meters, compared to the opposite case.

The weaving of Mosi(fine ramie) in the Hansan region was inscribed on the representative list of the UNESCO intangible cultural heritage in 2011. Unlike other fabric, as the Mosi is very sensitive towards humidity it needs different conditions for its workspace. The Hansan region is near the sea with many mountains around where it is easy for the Mosi to grow and is an appropriate place to weave Mosi. Recently the manpower for weaving of Mosi in the Hansan area is decreasing with the decrease of workspace drastically. After the investigation of workspace for the weaving of Mosi in the Hansan area, most of the places were done in individual houses and it could be classified in 1. Mosi storeroom, 2. Shed(Gwang che), 3. Dugout hut, 4. Under the toenmaru The depth of the dugout hut and under the toenmaru is around 80~60cm which is similar with the depth of the prehistoric dugout hut houses. The towns for weaving of Hansan Mosi are formed mostly in the Seochungun district, but the Hoamri Hansan-myeon and Gayangri Masan-myeon has the most traditional workspaces and they are still forming and maintaining the traditional town composition. However the numbers are too small and maintaining the traditional town is getting more difficult, so a plan for the maintenance should be made to continue to keep it as UNESCO intangible cultural heritage.
