Study on Environmental Impact through Analysis of Materials Used for Apartment Complex

This study has analyzed the LCA of apartment complex to quantitatively evaluate the environmental impact of materials used for material production stage in the entire cycle. This study has also presented methods to simplify environmental impact evaluation on apartment complex by selecting major materials. The research findings on the environmental impact of 27 units of apartment complex are as follows. Sales facilities of per unit area (/), which constitutes the complex had the biggest impact of , followed by other facilities (), welfare facilities (), underground parking lot (), apartment buildings (), and common areas (). Meanwhile, major materials were selected as follows: 15 types of apartment buildings; 5 types of underground parking lots, welfare facilities, and sales facilities; 5 types of other facilities; 26 types of common areas.

Variation of Energy Consumption in Barracks through Simulation by Year of Completion

Purpose: The purpose of this study is to analyze & suggest the variation of energy consumption consequent on thermal insulation performance strengthening from early 2000s when modernization of barracks began until the present targeting a large barracks. Method: To carry out this research, this study surveyed the standard of thermal insulation by year, which is being applied to a barracks by conducting literature search, and selected the standard model for a barracks. Also, this study analyzed energy consumption by year & region by performing simulation(ECO2)of the selected standard model. Result: As a result, it was analyzed that in case of a building which was completed in 2015, the energy consumption for air-conditioning & heating, lighting, and hot water supply over the year 2000 reduced by 11% on the average in central district, 10% on the average in southern district, and 17% on the average in Jeju, respectively.
