Heat island is caused by changes of land coverage structure of cities and use of energy in buildings. As a result energy use in buildings get to increase further followed by rising of GHG emission and deteriorating climate change. Eco-friendly housing complex is a kind of plan that applies environmental control elements like water and green spaces to housing complex. With these methods, it can be expected to create thermal environment of indoor and outdoor. In this paper quantitative examination is studied on using CFD to find out the effects of river, water permeable, parks and planting on thermal environment. And by comparing field measurements with CFD results which are aimed to development phase housing complex, feasibility and usability of the CFD analysis results are confirmed. And also, analysis on the ventilation performance followed by natural ventilation system is analyzed by selecting one building in housing complex. Based on the results, the possibilities of energy reduction through making thermal environment and applying natural ventilation are studied. With these outcomes, creating thermal conditions and using natural ventilation would be contributed to GHG reduction.

The environmental control systems used in educational facilities are diverse and obsolete. To provide safety for students and a pleasant learning environment, various systems are installed in learning spaces. In this study, on-site statistical surveys and energy consumption analyses were conducted in ten educational facilities in South Korea. Through awareness surveys of the persons in charge of education facilities, the energy conservation requirements were investigated. The system configuration was generalized according to the energy source, and through this, it was possible to determine the type of system used.

The predictive models have been proposed for managing building energy usage targets. In this study, we conducted an accuracy analysis of the energy consumption prediction model of educational facilities. We compared the primary energy consumption data of educational facilities with the results of the forecast model. The model based energy usage result showed 2~5 % forecast accuracy in the low level unit area of education facilities.
