  • Recently, biomass application for energy is getting more interests from many countries since biomass is widely available over the nation wide, whereas fossil fuels are produced in several limited regions. Recognizing the importance, government is promoting renewable energy use in Korea. The locational characteristics of the existing biomass potential directly can be used to decide scale of power plant for local agricultural facility. Although there are a few studies on feasible biomass potential in local areas, it is expected that both government and commercial sectors recognize the potential of biomass energy and the importance of reducing greenhouse gases. When planning biomass energy systems, biomass price is determined by the costs of collection, transportation, chipping, drying if required. In this paper investigates the economic and spatial characteristic of biomass location by land use map. However typical area of each categories in local region is not correct to agricultural census data. Therefore we concerned about how to calculate feasible biomass potential which it can be describing total amount of plant scale, and to match both of data. Even though its spatial distribution, in rural area in Korea, to expand biomass energy programs in the area, government serve to find areas of higher biomass production with suitable locations for plants to convert to bio-energy in order to increase the usage of renewable energy.

  • The purpose of this study is to present an integrated analysis for energy use and its patterns as vertical locations of the dwelling units in apartment buildings which are located in an urban area and constructed by a renowned contractor. In order to enhance the effectiveness of the method, the original data of electricity, water, and gas bills which directly reflect the energy use are sorted and analyzed into several groups as vertical locations in each building. And also, by use of comparing and contrasting the data on a monthly and yearly basis, the accuracy of analyses for seasonal energy use and its patterns is strengthened. Comparative analyses used in this study describe the results that vertical locations of dwelling units do not have much influence on electricity and water usage, but are closely related with gas usage for a heating season. According to the analysis of gas usage, the units on the ground and right above pilotis need enhancement in the insulations for heating to mitigate energy loss. Also, the analysis for the middle floor units in each group describe the fact that the gas usage of the units on the ground is consumes 1.5 times greater than that of the typical floors. Therefore, enhanced insulation strategies need to be considered against the adverse condition that the heat loss increases as the wall facing the outside air increases or as the wind velocity increases through the pilotis.

  • Load Management, is originated from efficiency improvement of energy use, or energy conservaion. Traditionally, electric utilities have constructed new power plants to meet the steadily increasing electricity demand. Power development planning, however, is becoming more difficult in the countries like Korea, Japan, and the United States, and increasing concerns about global environmental problems necessitate changes from existing supply-side options based on fossil-fuel to environmentally agreeable supply strategies. This paper discusses the demand side management strategy with emphasis on the concept, implementation scheme, and current practices employed in utilities.

  • Rural villages have many problems such as the collapse of rural village communities with continued over-depopulation and aging, reduced functions of towns and villages, deteriorated services with changes in the structure of settlement class and decreased use of the facilities. they also have difficulties in maintenance in spite of the increase of the roles of rural village community facilities. Various plans for the utilization of community facilities to promote the vitality of rural villages and the revitalization of communities have been needed. Thus, this study aimed to offer basic data to seek for future plans to utilize community facilities and reconstruct communities through an analysis of the current uses of energy and community facilities in rural villages. The results indicated that the consumption of petroleum was highest in mountain villages at an average of 187,475 won/month($137{\ell}$), followed by fishing villages at an average of 144,142 won/month($104{\ell}$) and rural villages at an average of 126,070 won/month($93{\ell}$). The rate of utilization of community facilities was reversely highest in rural villages at 84.3%, followed by fishing villages at 61.1% and mountain villages at 40.7%. This research also found that households saved energy when they used community facilities and areas with a high rate of utilization of community facilities at a lower average temperature in winter. It saved approximately 33% energy compared to other areas. Finally, efficient and economical methods for community facilities in villages to be newly developed and the remodeling of existing facilities should been needed in the future to contribute to reconstructing rural village communities that face a crisis of maintenance or abolition.

  • It has been a serious problem to consume the energy of apartment while increasing to use of heating & cooling System because of residence environmental upgrades. Great attention has been shown to the problem of the rental apartment, so there are few reports of energy consumption about the rental apartment in korea. To solve the lack of housing, our country has supplied an enormous volume of apartments, and these days it occupies 75% of our buildings. As apartments occupy most of our housings, the rate of energy usage from them are also high. On this, setting apartment energy reduction as a target, by researching the actual conditions of energy consumption and drawing a basis data, we can apply this as a way of saving energy, rationalization of the scale of energy supply facilities and a standard when planning facilities. To grasp the present condition of energy usage of the urban rental apartment, this research analysed the use of electricity, gas and water monthly and annually of a rental apartment that is located in Daegu. The results showed that in 2003 the electricity usage was 1,198MWh but 1,315MWh in 2007, which means 9% of electricity usage increases every year. The average of water usage was $85,072\;m^2$ per year and typical energy consumption unit was $604.2\;MJ/m^2$ on $74.4\;m^2$ of area and $448.8\;MJ/m^2$ on $105.8\;M^2$. By showing the usage of energy and water of the urban rental apartment, understanding the tendency and preparing an typical energy consumption unit standard through this research, apartments should use energy more efficiently.

  • Korean agriculture experienced rapid changes in its production structure to respond fluctuations on external conditions, and these changes have increased the dependence between agricultural resources and negative environmental externalities from agricultural production. As a tool for managing agricultural resources and reducing negative environmental effects from agricultural production, this study employs water-energy-food nexus for integrated resource management. To show the necessity of an integrated approach, this study evaluated three policy scenarios including changes in capital interest, water capacity, and energy cost. The results show that three scenarios have unintended consequences for farmers' incomes and their use of resources. Also the unintended consequences of government policies also affected farms' vulnerability to environmental changes. In particular, the expansion of financing for the establishment of non-circulating water curtain facilities did not have a significant effect on the crop switching of farms. In addition, increasing the amount of available water through the aquifer recharge project leads to the installation of non-circulating water curtain facilities in zucchini farm. It raises dependence on groundwater in agricultural production, thereby increasing farmers' vulnerability to groundwater shortages. These results imply that the agricultural sector needs to consider the interrelationship between agricultural resources when designing or evaluating policies.

  • The aim of this study was to present the direction of sustainable urban regeneration through the study of planning characteristics of urban regeneration reflected upon 'SymbioCity' concepts. This study was carried out through theoretical review and case study. In the theoretical review, the theory of 'SymbioCity', one of Sweden's representative urban development models linked to the concept of sustainable development, was reviewed and the framework was derived based on this theory. The framework of this study was finally derived from 'energy', 'ecology and environment', and 'historical and cultural resources'. The case study was conducted by selecting three urban regeneration projects($V{\ddot{a}}strahamnen$ BO01, Royal seaport and HafenCity Hamburg) in Sweden and Germany. Based on the results of case analysis, the direction of sustainable urban regeneration is as follows. First, in terms of energy, we should pay attention to synergy between energy and waste and energy production. Second, in terms of ecology and environment, plans should be made to maximize the use of existing resources in order to conserve natural resources and reduce energy consumption and economic costs. Third, in terms of historical and cultural resources, it is necessary to consider ways to preserve and recycle existing buildings with historical and cultural values. Finally, for the successful application of the planning elements, it is necessary to find the most appropriate application method through steady R&D in the country or project unit.
