This step involves analyzing the data collected during the LCI phase and assessing its significance in relation to the established impact categories. The LCIA provides valuable insights into the material’s overall environmental footprint.
4. Interpret and Report Results
The final step is to interpret and report the results of the material lifecycle analysis. This includes summarizing the findings, analyzing the implications of the data, and presenting recommendations for future decision-making. Clear and concise reporting ensures that the analysis is accessible and actionable for construction professionals.
By following these procedures, construction professionals can get a full grasp of the environmental implications connected with the materials utilized in their projects.
