This LCA looks at the cradle to grave operations of a building, quantifying the environmental impacts of the materials, production process, transportation, operating use, deconstruction, and disposal. There are several environmental categories that can be identified for evaluating global impacts including global warming, ozone depletion, eutrophication, acidification, smog formation, particulates, and fossil fuels. According to the International Organization for Standardization, there are four phases for performing LCA of a building: goal and scope definition, life cycle inventory (LCI), impact assessment and analysis of results. The goal and scope defines the intent of the LCA (cradle to gate, cradle to grave) and the limitations. The LCI is a data collection process that quantifies the materials being used and their energy inputs and outputs. The impact assessment looks at the LCI damage it may have on the environment.
