Comparison of Environmental Impact Analysis of Two Typical Construction Windows Production

摘要

The energy consumption of window accounts for nearly half of buildings. The purpose of this study is to compare the environmental impact of plastic windows and aluminum alloy windows production, including resource and energy consumption, waste emission. The result shows that energy consumption of plastic window production is only 0.24 times of aluminum alloy window production, and the overall environmental impact of the former is 30% of the later. This study is a quantitative description of energy consumption and environmental impact of two windows production pattern, which intends to fill the blank in LCA field of windows in China.
