Life-Cycle Assessment (LCA)
“A Life Cycle Assessment is defined as the systematic analysis of the environmental impact of products during their entire life cycle.” –Thinkstep
SLIDE 4
Whole-Building Life-Cycle Assessment (WBLCA)
- A life-cycle assessment performed on a
whole building
- Incentivized in LEED v4 and v4.1
- Different requirements between these two
rating systems
SLIDE 5
Impact Categories for LEED
- Global warming potential (embodied
carbon)
- Ozone depletion
- Acidification
- Eutrophication
- Smog formation
- Depletion of non-renewable energy
sources
SLIDE 6
Points for LEED v4
- Compare design building with a baseline
building
- Show 10% improvement in at least three
categories
- Don’t slip more that 5% in any of the other
three categories
- Get three points
SLIDE 7
Points for LEED v4.1
- 1. Conduct a WBLCA: one point
- 2. Show 5% improvement in three
categories, including GWP: two points
- 3. Same as LEED v4
- 4. Include reused materials; show 20%
improvement in GWP; show 10% improvement in two other categories: four points
SLIDE 8

- Use a whole-building LCA software tool
- Select from several common tools
