  • The main idea of this study is to propose a BIM-based automation system drawing up a report of energy conservation plan in the architecture division. In order to obtain a building permit, an energy conservation plan must be prepared for buildings with a total floor area of 500m2 or more under the current law. Currently, it is adopted as a general method to complete a report by obtaining data and drawings necessary for an energy conservation plan through manual work and input them directly into the verification system. This method takes a lot of effort and time in the design phase which ultimately increases the initial cost of the business, including the services of companies specialized in the environmental field. However, in preparation for mandatory BIM work process in the future, it is necessary to introduce BIM-based automatic creation system that has an advantage for shortening the whole process to enable rapid permission of energy-saving designs for buildings. There may be many methods of automation, but this study introduces how to build an application using Dynamo of Revit, in terms of utilizing BIM, and write an energy conservation plan by automatic completion of report through Dynamo and Excel's VBA algorithm, which can save time and cost in preparing the report of energy conservation plan compared with the manual process. Also we have insisted that the digital transformation of architectural process is a necessary for an efficient use of our automation system in the current energy conservation plan workflow.

  • The research examines individual environmental characteristics, the consciousness energy conservation and behavior level of college students that relate to the experience of taking courses on residential energy use held in college, as well as the influence of experiencing school education in the past. This is to ultimately evaluate the effect of school education on the consciousness of the energy conservation and behavior level of college students at present time, in order to assist in proposing a direction for the school education on residential energy use. The results of the research can be summarized as follows: First, there appeared a gap between the group that has attended courses on residential energy use and the group that has not in terms of their major, school year and the level of consciousness of the need for energy conservation. Second, students that have attended courses on residential energy use in college were reported to have received more training in high school through textbooks and guidance of teachers and have more experience in special education. And third, it appeared that taking courses in residential energy use by college students are influenced by personal factors such as their school year and gender, major, contents of their high school textbooks and the level of consciousness of the need for energy conservation.

  • Many papers have recently been presented to develop energy functions for power systems. However, earlier studies adopted case-by-case approaches, which failed to give a general approach to deal with various kinds of generator models. In this paper, two useful theorems are developed regarding the integral relationships of the generator power versus its phasor current and voltage. By using the proposed theorems, an exact energy conservation law can be derived from the complex integral. The proposed energy conservation law, which is free of the generator model, can be utilized to develop energy functions for various kinds of generator models including the speed governors and exciters. An illustrative example is given for a multimachine system with the Eq' model of generator. This thesis also shows a possibility of more accurate and fast stability analysis by using the proposed Energy Conservation Law.

  • In order to analyze the effect of environmental protection on wind energy dissemination quantitatively, the onshore wind resource potential is estimated using Environmental Conservation Value Assessment Map and Korea Wind Resource Map. The onshore wind resource potential of 11 GW is calculated if wind farm development is prohibited within Class 1 area of Environmental Conservation Value Assessment plus 500 m buffer area. Therefore it is worried that environmental protection would be a practical barrier of accomplishing 4,155 thousand TOE target of wind energy dissemination until 2030.

  • The objectives of the study were to determine 1) if energy consumption and conservation vary in clothing, food, and housing with independent variables-size of household, homemaker's age, employment, and level of education, level of living, type of house, electricity use, and all energy use, and 2) if there is a correlation among energy conservation practices in clothing, food, and housing. Questionnaires wee given to the randomly selected homemakers in Seoul in July, 1980. Data from 620 responses were analyzed by F-test (Analysis of Variance) and Correlation. The results are as follows: 1. Clothing (1) the scores of the conservation practices I clothing were generally high. /However, it was found that a) they did not practice in wearing heavy under clothes and behavior outer clothing to cope with cool room temperature in the winter, b) they did not use bleach for laundry, but they used boiling method, and c) they did not have enough knowledge on Permanent Press finish. (2) energy conservation practices in clothing were significantly related to level of living and homemakrer's level of education. a) The higher the level of living, the higher scores in the knowledge were found. b) the higher the homeakcer's level of education, the higher scores in the knowledge and ironing were obtained. 2. Food (1) The scores of the conservation practices in food were generally high. However, it was found that scientific cooking methods were not performed such as a) to use measuring spoons, cups, and timers, b) to practice a simple method in using solor energy for warming water, c) to use thermos for the hot water tea or coffee, but they boiled water whenever necessary, and b) to use the pressure cooker whenever possible. (2) Energy conservation practices in food were significantly related to homemaker's employment and type of dwellings. a) The scores of full-time homemakers (not gainfully employed) were higher than gainfully employed homemakers. b) Families in traditional Korean dwellings revealed higher scores than those in apartment or western style dwellings. 3. Housing (1) The scores of the conservation practices in housing were generally high. However, it was found that a) they did not install fans in the kitchen, bathroom, and attic in the summer, b) they did not install a humidifier for tolerating a lower room temperature in the winer, c) they did not practice to make plans for the door of the refrigerator remained open for the shortest time, d) they did not install or use a local lighting with a general lighting for reading and cooking, and e) they usedaluminum foil without the knowledge of the heat reaction of its shiny and dull sides. (2) energy conservation practices in housing were significantly related to homemaker's employment and level of education, economic status, types of dwelling, and all energy use, a) Full-time homeakers had higher scores than gainfully employed homeakers. b) the higher the homemaker's level of education and economics status, the higher scores were obtained. c) Homeakers with their own house scored higher points than those with rented houses. And families in apartment or row houses scored higher points than those in traditional korean or western style dwellings. d) The higher the consumption rate of electricity and all energy, the higher scores were revealed. 4. correlation there was a significant correlation among energy conservation practices I clothing, food, and housing.

  • It is a global consent that we should conserve our energy consumption, due to our awareness to the environmental problems and the limitedness of the natural resource. In the country, the level of energy consumption is more than it is needed, according to its living standard and the proportion of resources imported from other countries. Educational program focused on energy conservation is essential to overcome these problems. This paper outlines a basic study on the development of an energy conservation education program for children. This program makes students aware of the importance and difficulties in energy conservation. The students can then make their own contribution and besides circulation of resources and improvement of health problems.
