Investigation of Implementation Stages and Boundaries of Life Cycle Assessment Method

With the massive growth in the population of the world, the rapid consumption of natural resources and unorganized urbanization causes an impact of air pollution, water pollution, environmental destruction, and global warming to increase. With these factors threatening human health, the term sustainability gained popularity for restoring the deteriorating ecological balance. This awareness is called green buildings in the construction sector. The purpose of sustainable green buildings is the restoration of corrupted order and utilization of energy effectively. The Life Cycle Assessment method is one of the assessment systems developed for reducing the environmental impacts of products/services in evolving green buildings. Life Cycle Assessment determines the environmental impacts of the process that studies the extraction, use and disposal of the material by taking the life long evaluation of any product. As a result of this study and the in depth review of the literature portrayed the pros and cons, and the applications of the terms sustainability, green buildings and life cycle. The application stages of Life Cycle Assessment are defining the purpose and concept, stock analysis, analysis of effectiveness, evaluation of subfields with a determination of the boundaries as initial, intermediate and final. With the final analysis, the aim is to produce environmentally friendly products/services.
