B07 - Kicking Carbon for Credits: LEED v4 Whole-Building LCA

Wednesday, November 8 from 4:00 PM to 6:00 PM | 257AB « Back

Abstract Text:

Even before a new building powers up, its materials have already taken a heavy toll on the environment. New credits in LEED v4 focus on reducing building life-cycle impacts, yet many professionals are intimidated by the unfamiliar practice of Life Cycle Assessment (LCA). Focusing on practical implementation, attendees will gain an understanding of the strategies required to reduce environmental impacts and achieve points for the LEED v4 whole-building LCA option in the Building Life-cycle Impact reduction credit. Using a diverse set of case studies that achieved significant LCA impact reductions, the opportunities and challenges of meeting the credit criteria from the perspective of architect, consultant and engineer will be demonstrated. Projects highlighted will include a tall mass timber building, multi-unit housing complex, high-rise concrete tower and an airport terminal. After providing a technical foundation for LCA, the panel will engage in a probing and frank discussion of key topics the design teams faced when performing LCAs, including: selecting the right LCA tools, the process of defining a reference building; determining the greatest opportunities to achieve the credit; what time, effort, and compromises were required; and how the entire team, including the client, was engaged in the process.

Learning Objectives:

Compare and contrast current research and leading design practices for whole-building Life Cycle Assessment (LCA) with the LEED v4 BD+C Whole Building LCA option in the Life Cycle Impact Reducation Credit.

Understand and outline the critical steps and key methods to meet the requirements of the LEED v4 BD+C Whole Building LCA option in the Life Cycle Impact Reduction credit.

Estimate the effort and opportunities of pursuing this credit in early design.

Communicate and implement strategies for reducing the ‘embodied’ environmental impact of a building and achieve the points via the LEED v4 BD+C Whole Building LCA option
