This study presents a demand modelling for landfill gas, which is used as alternative energy source for district cooling business. By analyzing the cost minimizing behavior of producer facing with three alternative energy sources such as electricity, cooling heat water, and gas, a demand function for landfill gas is derived from the optimal operating time of gas fired production facility, and estimated using unpublished data, which are associated with Seoul city's development plan for Sang-am area. The estimation results repeals that Seoul City could supply the land-fill gas of 13.76 million cubic meters each year at the price of about 16 won per cubic meters. However, if the investment costs associated with installation of gas collecting facilities are treated as sunk costs, annual amount of gas supplied is expected to increase to 14.22 million cubic meters at a lower unit price of 14.76 won.

This study is to solve a problem of elementary school facilities' insufficiency in the reconstruction area of Ichon 1-Dong in Seoul. Results of this study are as follows; 529 students will be increased to Shinyongsan elementery school in 2004; 1,206 students will be increased after the reconstruction projects is completed in Ichon 1-Dong. By accepting these students I suggest alternatives in three aspects; the application of the existing facility, the establishment of new school facilities and the constraint of student demand by reconstruction development. There are some limitations and more themes must be solved. First of all, the flexible standards corresponding to various community's characteristics such as a builtup area or a new development area are needed. Secondly, the community plan must be prepared for many urban developments in a community area. Thirdly, reconstruction development must have an alternative for establishing public facilities. Lastly, the decision making system reflecting the communities' goals must be required to choose the best alternative for the community's public facilities.

It is practically very important in multi-criteria long-tenn IRP process to develop the set of candidate resource plans that meet following two conditions. First, the number of resource plans should not be too large for computer job. Second, the unknown best plan should exist among the set of candidate plans. In this paper, several novel procedures are developed. The main idea of the procedures is the two-stage approach. The first stage is to find the set of feasible resource capacity mixes in given target year(s). And, the second stage is to find the set of alternative paths of resource options for each resource mix determined in the first stage.

The long-term electricity resource planning of electric utility has undergone significant change during the past decade. The current resource planning can be considered as multi-objective decision making procedure under the various uncertainties such as demand growth, construction cost, fuel price, environmental regulation, plant site, financial adequacy, new technology advent and so on. This paper presents a standardized electricity resource planning scheme using the strategic planning concept. EGEAS computer model was fully applied to indentify feasible alternative plans and simulate various attribute values corresponding each alternative plan and future. As a case study, a hypothetical long-ten capacity expansion planning problem is analyzed.

The purpose of this study is to suggest an environmentally friendly system of ecological village with the reference to amish village, and also to make a proposal for application skill of ecological village. Ecological village is environmentally friendly lifestyle and an alternative plan of environmental pollution. There is growing international scientific consensus that human activities are having a discernible effect on the global climate. Up to now, the development of ecological village has been actively initiated and still continues by some venture farmers with a vision and strong will. These study results are definitely very conducive to spread ecological village knowledge among the public.

The Seoul Housing Corporation pronounced an alternative design competition and a bidding for Eunpyeong New Town in December of 2004. At first many construction companies were interested in the first New Town Project. But at last a few companies had proposed the alternative design and construction cost. This project needed a conjunction of design ideas and technology know-hows. And the client wanted the brand power of construction company. Ultimately the Corporation hoped that the first New Town Project will end up with high quality successfully. This competition had started with the original construction drawings. Then it needed some alternative ideas and the lowest cost. There were two drawings of non changeable part and changeable part. Non changeable parts are structure like housing unit plan, underground parking lots. Changeable parts are outdoor layout, interior design and building facade. So we tried all ideas of landscape technology and design principles within limited guidelines. The author applied new technology like tilted rooftop greening and sustained container greening on high-rise apartment house. This green technology will be the first trial in Seoul and in the world as well. Daewoo Corporation have accumulated greening technology through the researches by national funding since 2002. Through this New Town Project the green technology will go forward step by step.

Bioenergy can be obtained from various forms of biomass such as agricultural, food processing, and municipal wastes. Recently, its importance is recognized more seriously because of its positive impacts on economic and stable energy supply and environmental sustainability. Despite its advantages, bioenergy has not been used as much as it was expected, nor has it been developed to the level of attractive commercialization in energy market. The main reasons for the sluggish progress have been analyzed by comparing the bioenergy policies in Korea and U.S.A. Both Korea and U.S. governments have recognized the importance of bioenergy and put in various efforts to promote the use of bioenergy. Both governments have legislated alternative energy promotion plans that support R&D, tax reduction, rewards, and low interest loans. However, it is suggested that the bioenergy policy and plan juxtapose the financial supports (R&D, tax exemption, low interest loan, education, etc.) with strong mandates and obligations. Although imposing strong mandates prerequisites the economically attractive and feasible technologies, it can motivate and speed up more effective technology development, in turn. In addition, the bioenergy R&D support must include studies on commercialization and marketing as well as process development. R&D on the socioeconomic effects of bioenergy should also be supported. Lastly, decision making processes for the bioenergy policy, and for alternative energy overall, must include environmental agencies for taking advantage of environmental benefits of bioenergy.

BTL사업 형태로 발주되는 교육시설의 공사에서는 소요 공기 최소화와 임시교사 설치로 인한 별도의 비용 소모, 그리고 학기 중에 학교 사용자들이 겪는 불편사항으로 주무관청, 민간사업자 그리고 학교사용자의 갈등이 깊어지는 문제가 발생하고 있다. 본 연구에서는 이러한 당면 과제를 공법적인 측면에서 해결하고자, 기존 학교 공사에 일반적으로 적용되는 RC공법과 최근 몇 년 사이에 교육시설의 대안공법으로 주목받고 있는 모듈러 공법을 포함한 몇 개의 대안을 설정하고 교육시설의 BTL사업에 적합한 건축공법을 제안하였으며 각 대안에 소요되는 공사비를 산출하고 공사기간을 분석하여 이를 평가하였다.
