KEY TECHNOLOGY OF GREEN ECOLOGICAL AND ENVIRONMENTAL PROTECTION CIVIL BUILDING DESIGN

Human over development and construction behavior lead to environmental degradation, resource shortage and global warming, and architecture is one of the main reasons. Since 2008, green building has become the development direction of energy saving, carbon reduction and environmental pollution reduction in the construction industry, and has achieved great development. Based on the above background, this paper quantifies Life cycle carbon dioxide emissions (LCCO2) and Life cycle carbon emissions (LCC) of green technology. Taking green residential building as an example, this paper studies the effective selection of green technology in the planning stage of green residential building. The results show that based on the evaluation of LCCO2 and LCC, the weight values of energy saving, material saving, water saving, land saving, outdoor environment and indoor environment calculated by Analytic hierarchy process (AHP) are 0.4592, 0.2498, 0.0024, 0.0948 and 0.0838, respectively. Through this research and analysis, this paper can guide designers to select green technology in the planning stage, so as to reduce carbon emissions and protect the environment.
