2 Learning Objectives FAQ s Care in At the end of this program, participants will be able to: 1. Describe life cycle assessment, its use in the marketplace and how it is influencing the design of buildings. 2. Learn how LCA has been integrated into building codes, standards,, and the Living Building Challenge 3. Explain how Environmental Product Declarations are making the results of life cycle assessments more widely available to design professionals. 4. Compare the LCA tools available for use by designers. care about Embodied Impacts? replace what is in? What are the Benefits of LCA? use LCA?
