3. overview • DEQ Home LCA • review results, discuss implications • prepare for next week’s readings • Homework for next time

4. learning objectives • Get experience with looking at LCA results • Understand and summarize main points • Look at various ways of presenting information • Discuss implications for various types of decision making

5. home LCA • briefly summarize (cite charts to make the point) • main purpose? (particular angle (due to funder)?) • functional unit? • What is being studied here? What are the impact categories? • strategies called out in the report? • other points? • sensitivity analysis and pie charts: if you remove a big slice, it all changes (including high-priority actions) (this is a general observation) • comment on: • what to do with existing homes • implications for durability/longevity? • putting results in context of personal/HH consumption

6. home LCA • fair game • If life-cycle stages are in rows and impacts are in columns, what are the rows and columns of the LCA? • What are the highest-impact items? Name a few. • Does the answer to that depend on who the actor is? Give examples. • To what extent and in what actions are GHG reduction and waste reduction correlated? (carbon goggles) • What major resource impacts associated with a home purchase and use are missing? • where this material will/could resurface • your personal climate action plan • discussion of McKinsey’s Pathways • subsequent discussions of carbon goggles

7. initial study question and purpose Initial Study Question: Over the life of a home, how can you use fewer building materials or prevent waste? Purpose: Support decisions by DEQ to form programs, policies, and actions to prevent waste generation from the residential building sector in a way that maximizes overall environmental benefits.

8. the functional unit: standard home • 2262 square feet • 3 bedrooms • 2 baths • 2 car garage • 2.5 occupants • “move-in ready” • includes original and replacement materials • vinyl windows • asphalt roof • gas furnace, no A/C • designed to 2008 Oregon energy code • energy use modeled for Portland, OR climate ***Lifetime = 70 years***

9. I’ll give it to you blank next time and you can fill it in Note how hard it is to zero in on “before”, “during” and “after”

10. DEQ Home LCA: goal definition and scoping

11. activity 1: write out main lessons of study • use your knowledge of the portion you read • sum up primary lessons into a few bullets • imagine you are responsible for: • policy decisions • certification implications • a home buying decision

12. Major take-aways? (green & dotted bars only)

13. Major take-aways? (yellow bars)

14. Major take-aways?

15. applied thinking two views of US emissions • implication: transform our economy *

16. applied thinking two views of US emissions • implication: transform our economy *

17. applied thinking two views of US emissions • implication: transform our economy * “On a per-home basis, constructing smaller residences is among the most influential options for preventing waste and reducing a variety of environmental impacts, including Climate Change.”

18. applied thinking two views of US emissions • implication: transform our economy * What are possible policy implications? What are possible certification implications? What are possible home buying implications?

19. example: building life-cycle BEFORE DURING AFTER

20. Which stage determines all decisions? BEFORE DURING AFTER

21. Which stage lasts the longest? BEFORE DURING AFTER

22. Which stage costs the most? BEFORE DURING AFTER

23. life-cycle cost for MediumStandard Home

24. “before” “during” “after” Version 1: life of the materials

25. “before” “during” “after” Take-away: what can you do to extend the life of the materials?

26. “before” “during” “before” “during” “after” Version 2: life of the house

27. Which stage emits the most GHGs? BEFORE DURING AFTER

28. climate impacts from Medium Standard Home

29. “before”: materials “during”: energy consumption “after”

30. GHGs from production, landfill and recycling

31. Impacts from materials (over 70 years)

32. Why are energy and climate impacts different for some materials and the same for others?

33. life cycle GHG impacts ~15% ~80%

34. life cycle non-renewable energy impacts ~70% ~25%

35. apples, oranges, pineapples, sheep, toasters

36. activity 1 continued: New lessons to add? • use your knowledge of the portion you read • sum up primary lessons into a few bullets • imagine you are responsible for: • policy decisions • certification implications • a home buying decision

37. Major take-aways?

38. I’ll give you the list next time and ask you to draw it on a linear scale

39. homework • keep reading DEQ Home LCA • be prepared to discuss results • start your personal carbon footprint and climate action plan
