  • The smart energy system is the integrated power system in which the power components including central station generation, distributed generation, renewable power generation, energy storage, and communications and controls are complexly connected with each other. In smart energy system, it is very important how to configure the diverse power generations and how to determine the operation mode of the chosen components with economic feasibility. In this study, we introduce the optimal planning method based on both economic feasibility and load profiles and its applications for the smart energy system in apartment. This method was considered very useful to determine the configuration and to decide the optimal operation mode of the smart energy system.

  • Currently energy use planning council system is mandatory especially for the urban development project planned on a specified scale or more. The goal of existing demand prediction was to calculate the maximum load by multiplying energy load per unit area by building size. The result of this method may be exaggerated and has a limit in the information of period load. The paper suggests a new forecasting process based on standard unit household in order to upgrade the limit in demand prediction method of multi-family housing complex. The new process was verified by comparing actual using amount of multi-family housing complex to forecasting value of energy use plan.

  • This study prepared the list of planning components required for constructing environment-friendly industrial complex and grasped major environment-friendly planning components by measuring the importance per each planning component via the survey for specialists. As a result of measuring the importance of planning component according to each field for constructing environment-friendly industrial complex, it is indicated that important planning components in natural environment field are establishing complex location plan considering its configuration and slope, excluding projects for steep slope-land, establishing countermeasures for reducing contaminants per its source, and separated location of contamination industry around living space. In living environment field, proposed planning components having relatively high importance are separated location of pollution causing industry, establishing energy saving land use plan, linking with green way, circulation network plan, lowering noise level at roadside, plan for separating between pedestrian and vehicle, securing parking space, extending green park and proper location, installing green buffer zone, conserving and forming landscapes, land use for raising energy efficiency, and expansion of energy source. In case of ecological environment, core planning components such as conserving upper class of ecological naturality degree, conserving main habitat, and biotope forming plan are suggested. This study is limited to find out planning components for constructing environment-friendly physical environment of industrial complex which is a part of non-production process. The approach to solve environmental problem by linking spatially production process and non-production process. There is a need to conduct follow-up study to constructing technique for environment-friendly industrial complex considering production & nonproduction process afterward.

  • New renewable energy information becomes one of the greatest issues all over the world because of serious environment problems and limited fossil resources. The new renewable energy source information system is treated seriously for efficient management and distribution as dealing with these energy problems. However, it is difficult to manage and utilize new renewable energy information because gathering and surveying information is progressed individually in each research field. Therefore this paper will establish ISP(Information Strategy Planning) and propose the basic management system based-on GIS to analyze new renewable energy such as solar energy, wind power, small hydro, biomass, geothermal etc. and build the integration management system. The proposed integration management system can provide spatial analysis using thematic map, data search, data import/export and interpolation about users' queries.

  • The photovoltaic (PV) industry, which occupies about 80% share of domestic new and renewable energy (NRE) sales, has played an important role in the development of the Korean NRE industry. This was made possible by the government's implementation of the 3rd Basic New and Renewable Energy Plan, which promoted strategic PV R&D, infrastructure building, and a variety of PV deployment programs. For instance, 'One Million Green Homes', 'Feed in Tariff', and 'Renewable Portfolio Standards' programs contributed greatly to the dissemination of PV systems in the country. Furthermore, these programs were supported with more than 380 billion Won over 6 year period (2007~2012). The strategic PV R&D contributed to the fast follow-up in commercial technologies. Because of the recent, sharp decline in PV prices caused by oversupply and economic crisis in European countries, both foreign and domestic PV companies are going through painful restructuring. Under these circumstances, the Korean PV industry needs to find a new strategy for making a breakthrough, and in this sense a proactive role of the Korean government is desperately needed.

Through these close relationships the ecological housing estate could get more sustainability. With this consideration, this study consists of following three parts. First, we review the key issues of sustainability in ecological housing which are focused on the energy-efficient planning. Second, we extract the planning elements, legal regulation and evaluation index using the qualitative system dynamics that is found out all phenomenons from viewpoint of closed loop thinking and circular feedback system. Third, we analyse the correlationship among them in terms of energy efficient planning in the ecological housing estate. Finally, we summarize the findings toward sustainability in ecological housing estate through these analysis.

  • The forecasted energy shortage tends to encourage to develop the next generation energy to countermove the energy problems and the climatic change all over the world. Korean government is pushing ahead with the policy for 'Low Carbon Green Growth' to deal with climate changes and to overcome energy problems. And many studies for low carbon green city or zero carbon city have been progressed. In this study, energy plants and energy scenarios are selected by energy supply suited features of city at city plan. The method to evaluate energy scenario can be proposed to apply various energy plants for energy demand on city planning step and evaluation method can be systematized to be used by users. Also the calculated values are changed into index for comparison according to each energy scenario.

  • This paper aims to analyze architectural planning factors that could contribute to reductions in electricity consumption in the household of apartments, to apply energy saving methods at the design phase. These six architectural planning factors were orientation, building type (flat, tower block), standard floor access type (corridor access type, stair case type, EV hall access type), household location (floor), household opening type (one side opening, right angle opening, two sides opening or three sides opening), and bay on the facade (one bay, two bays, three bays, four bays), and these were derived from literature review. Household electricity consumption data were gathered from 2168 households with a total area of 135~150$m^2$ of 6 apartment complexes over 1000 households in Seoul. The annual characteristics of electricity consumption according to architectural planning factors were analyzed. And, variances between groups with respect to the mean of summer, winter, and annual electricity consumption according to each architectural planning factors were analyzed using ANOVA and t-test. The results showed that an annual electric energy saving of over 1000kWh was facilitated by these planning factors. In addition, high energy efficiency architectural planning factors based on the analysis were as follows: southwest orientation, flat type, corridor access type and staircase type, household loation below the 20th floor, two sides opening and three sides opening, and 2 bays and 3 bays.
