1. The Concept of Embodied Carbon A Life-Cycle Approach

2. Technology Racing Ahead

3. Machines have replaced manual labor

4. 200 years of carbon emissions

5. CO2 – Where does it come from anyway?

6. Lifecycle Embodied Carbon Embodied Carbon

7. Embodied vs. Operational Embodied Carbon –Life Cycle Assessment –Construction Waste Management –End of Life Assessment –Materials Reuse –Recycled Content –Local Content Operational Carbon –Transportation to/from site –Energy Performance –Energy Metering –Commissioning –Renewable Energy, Green Power and Carbon Offsets

8. OFFICE WAREHOUSE Life cycle carbon – Not one size fits all 75% operation 75% manufacture

9. Life cycle carbon- improving operational energy performance

10. RICS Standard Methodology – UK to Int’l

11. Embodied carbon is about material use: Average % of materials in different building types (AUT case studies) 11 Source: Nick Deeks (2011) «Understanding the measurement of Carbon» at RICS Oceania Annual Sustainability Seminar 2011 Concrete and Steel represent major share of materials used in all building types = Carbon Hotspots

12. Focus on what we know

13. Life cycle stages of a building based on BS EN 15978:2011 SCOPE OF THE RICS PAPER

14. Concept design - embodied carbon benchmarks

15. Detailed design - embodied carbon calculation methodology

16. Analysing the results

17. Motivation To Measure? Call to Action?

18. Rating Systems Surveyed New Building Rating Systems (Office) –LEED for New Construction v4 (4 th reading) –BREEAM Europe Commercial 2009 –DGNB New Office and Administrative Buildings –Green Star Office Rating v3

19. The Importance of Carbon in Rating Systems

20. Embodied Carbon as a proportion of Total Carbon

21. Best Practice – DGNB Ecological Footprint The ecological footprint of the building is calculated over the life cycle of 50 years. Within the life cycle, all stages are taken into account: Product stage, construction stage, in-use stage and operation of the building as well as end of life stages

22. Best Practice – BREEAM Green Guide

23. Best Practice – Green Star Individual Materials Mat 6/7 Aim – To encourage and recognize the reduction of embodied energy and resource depletion occurring through the use of concrete/virgin steel Mat 9 Aim – To encourage and recognize designs that minimize the embodied energy and resources associated with demolition. Mat 10 Aim- To encourage and recognize designs that produce a net reduction in the total amount of material used.

24. Best Practice – LEED Waste Diversion Construction and Demolition Waste Management –Divert at least 75% of the total construction and demolition material; diverted materials must include at least 4 material streams; OR –Do not generate more than 12,2 kg of waste per square meter of the building’s floor area.

25. We will not reduce energy use in construction!

26. Two solutions to the problem

27. We can (probably) tough it out HumansHomo Genus

28. But maybe not…

29. The Apollo Missions – 11 years, 17 flights Apollo Guidance Computer –.00004 GHz clock speed –4 KB RAM 5x IBM 365/75 –.01 GHz clock speed –8 MB RAM Apple iPhone 5 –1.3 GHz clock speed –1 GB RAM

30. The Apollo Missions – 11 years, 17 flights iPhone is 32,500 times faster and has 250,000 times more memory than the Apollo guidance computer iPhone is 26 times faster and has 25 times more memory than all 5 IBM 360/75 computers combined When will we spend 170 billion USD again?

31. Do we need 170 billion USD to change this graph?

32. Commercial solar cell efficiency today 14-19%

33. We’ll need to store energy
