  • Korean government has initiated integrated-energy business (IEB) in Mokdong for energy conservation in 1983. Since then, IEB has been steadily expanding. This paper attempts to apply input-output(I-O) analysis to examine the economic effects of IEB. A static I-O framework is employed, focusing on three topics in its application: the impact of the investment of IEB on the production of other sectors and the inter-industry linkage effect; supply shortage effects of the IEB ; and the impact of the rise in IEB rate on prices of other products. The paper pays closer attention to IEB sector by taking the sector as exogenous and then investigating its economic impacts. The results can be widely utilized in decision-making about IEB policy.

  • Necessity to install control towers has been studied to acquire overseas energy resources and to secure funds. At present, domestic energy companies do business independently. Institutions which support plant EPC companies as partners of package deal are separated. This causes the low records at package deal for overseas resources acquisition. Except UK and USA, nations which have major companies developed overseas energy resources early by promoting a large national company. Consequently, they currently have good records. This study suggests the necessities to install integrated control tower for overseas energy resources acquisition and securing funds and the following are the ways ; 1) promote a large national company by consolidation of separate energy companies, 2) install plant EPC promotion department which support private plant EPC companies, 3) make a integrated control tower in high level government office to connect between a large national company and plant EPC promotion department.

  • The domestic ESCO project was introduced in 1992 as one of the energy efficiency improvement programs. In recent energy market, the changes in the market conditions such as smart grid, renewable energy, and the importance of demand response became important issues. As the diversified business models are required, examples of overseas exercises are examined. Business areas in Europe or the US where the ESCO industry has been active include measures to improve the efficiency of energy facilities in all areas, ranging from energy supply facilities and energy services to end users. This type of ESCO overseas business model can be classified into various types such as project execution method, supplier demand management, financing method, climate change and emission rights, new and renewable energy, and other criteria. In this study, we propose to adopt IEC (Integrated Energy Contracting) contract method in domestic ESCO market for additional business models. Current convention of listing the specific individual business types being allowed by regulation turned out to be obstacles to the revitalization of the related market. In order to achieve the goal of energy conservation, it is recommended, instead, to revise the current funding guidelines to be a negative system.

  • We see an energy fucused smart city evolution of the UK along with the project of "Smart London Plan (SLP)." A theoretical logic of business model innovation has been discussed and a research framework of evolving energy focused smart city is formulated. The starting point is the silo system. In the second stage, the private investment in smart meters establishes a basement for next stages. As results, the UK's smart energy sector has evolved from smart meter installation through smart grid to new business models such as water-energy nexus and microgrid. Before smart meter installation of the government, the electricity system was centralized. However, after consumer engagement plan has been set to make them understand benefits that they can secure through smart meters, the customer behavior has been changed. The data analytics firm enables greater understanding of consumer behavior and it helps energy industry to be smart via controlling, securing and using that data to improve the energy system. In the third stage, distribution network operators (DNOs)' access to smart meter data has been allowed and the segmentation starts. In the fourth stage, with collaboration of Ofwat and Ofgem, it is possible to eliminate unnecessary duplication of works and reduce interest conflict between water and electricity. In the fifth stage, smart meter and grid has been integrated as an "adaptive" system and a transition from DNO to DSO is accomplished for the integrated operation. Microgrid is a prototype for an "adaptive" smart grid. Previous steps enable London to accomplish a platform leadership to support the increasing electrification of the heating and transport sector and smart home.

  • This study aims to investigate and analyze the overall recognition of the photovoltaic system for the application of BIPV(Building Integrated Photovoltaic) in Korea. For this purpose, a survey was carried on through questionnaires answered by 6 groups of experts such as construction engineers, registered architects, mechanical engineers, electrical engineers, university or college professors, and others who are ranked high in their companies or universities or colleges and who mostly seem to be eager to participate in the development of the PV system and to make a business of the system. The results of the survey are as follows: 1. About 95% of those experts who answered the questionnaire have known about renewable energy, and 93% of them are interested in solar energy as alternative energy 2. Host experts have a lot of information on the solar energy system, but have scanty information on the PV system. 3. The experts in the educational and research field have researched for the reasonable period of the participation in the development of the PV system and the period of making a business of the system. They judge that companies in the mechanical and electrical field will participate in the development of the PV system and will make a business of the system in 5 years. 4. The experts have thought that the PV system is designed not for economy but for the environment of the earth and that PV system technology in Korea is much lower than that in the advanced countries. 5. The experts hesitate to participate in the development of the PV system and to make a business of the system because they have little confidence in the economy of the PV system now and because they have thought that they will bear a great financial burden of construction cost 6. The experts judge that it is most desirable to apply the PV system to the rooftops of buildings. And they are greatly interested in the BIPV.

  • Power consumption in Southeast Asia is steadily increasing due to industrialization and the effects of hot and humid climates. However, there are not enough energy generation facilities and infrastructures to meet the growing demand because it is difficult to secure the construction and operation costs of the transmission and distribution systems. This study aims to develop a gas engine driven heat pump system that supplies heating, cooling and electric power to buildings. This system, besides its normal function to produce heat, has the capacity to generate electricity on a household level. This paper investigates similar cases overseas before developing the system. Through the investigation of commercialized similar systems, the level of technology and market trend of development system were identified. Features and specifications of commercial and industrial systems will be used for system development.

  • The driving force of the manufacturing field is members' mind-set and activity. However, there is no appropriate program of change management for workers who work in the manufacturing field. Most of the small group activities were focused on the fixed tools and processes to make improvement only, not the change itself. Therefore, it was difficult to have self generating energy without actually motivating people of change. Study of IFI(Integrated Field Innovation) means change of management. This study will introduces IFI which is a new methodology of change and innovation of workers, and will describe how workers participated in the activities voluntarily. The principle of IFI is that letting employees to find the problems of the sites -anything that makes employees considering as the problem while they are working- and solve those problems through any tools own their own. Workers do not have to waste their time on bounding by unnecessary tools and processes. There are several cases that company "D" has been actually applied the IFI methodology in 2008. Through these cases, IFI proved that it was a optimized methodology for workers who work in the manufacturing field.
