With the continuous development of the construction industry, the increasing pressure by the attention it brings to the environment. Throughout the life of the building process, the consumption of a variety of building materials and energy consumption will have a lot of environmental pollution, such as air pollution, water pollution, solid waste, pollution and so on. In order to analyze the impact of construction on the environment, we can use the building as a special treat, the introduction of life cycle assessment methods to evaluate the impact of buildings on the environment. Life cycle assessment (Life cycle assessment, LCA) is an effective environmental management tool, it is mainly to evaluate the environmental impact over the entire product life cycle (including raw material extraction, production, use and disposal stages). We must first identify the substances, energy consumption and pollutant emissions, environmental impact assessment and consumption and emissions, and ways to reduce and eliminate these effects of improvement measures. ISO14040 the LCA implementation steps are divided into objectives and determine the scope, inventory analysis, impact assessment and interpretation of the results of four parts. Inventory analysis and impact assessment is one of the more important part. In this paper, a life cycle assessment Suzhou Moon Bay International Center building (100m2 floor area). In the evaluation process, the life cycle of the building is divided into five stages, namely building materials preparation stage, construction stage of construction, construction and operation phase (running for 50 years), building demolition phase of construction waste disposal stage. LCA Research Center of the National Institute of Advanced Industrial Science and Technology, Japan developed evaluation system AIST-LCA Ver.2 the building to carry out environmental impact assessment, evaluation results for the operational phase of the construction and building materials preparation stage a larger impact on the environment, followed by for the construction of waste disposal stage and dismantle the stage, construction stage of construction with minimal impact on the environment. Impact of a larger type of impact on the environment, urban air pollution, eutrophication and global warming. Suzhou another multi-story building impact on the environment, the the comparative LCA evaluation results obtained ecological currency of the high-rise building eco-currency, multi-storey buildings greater than that of the multi-storey buildings have less impact on the environment and the software evaluation . Finally, analysis of the high-rise buildings and multi-storey building in energy use, land-use differences. The main purpose of this paper is to evaluate architectural impact on the environment throughout the life cycle. Realistic basis to seek changes in the starting point of the production process and the implementation of eco-design, to promote the development of green building materials, recycling of construction waste utilization, thereby improving the overall environmental performance of building products.
