1. Built Environment Sustainability: Perspective J. A. Vanegas School of Civil and Environmental Engineering College of Engineering Georgia Institute of Technology Atlanta, Georgia, USA

2. The point of departure: people want/need to sustain what we all do...

4. …And within this world, we want/need to sustain...

5. Individuals Communities Organizations Families BodyMind HeartSoul …People…

6. AirWater SoilBiota (Plant and Animal Species) Global Local …And the Natural Environment…

7. …But, this is not enough; we also want/need to sustain...

8. Production Systems for Products Production Systems for Services …The Industrial Base… Production Systems for Goods

9. Residential Facilities Civil Infrastructure Systems Non- Residential Facilities Industrial Facilities …And the Built Environment…

10. Stated in another way, we want/need to sustain the resource base that provides the foundation upon which any society exists, develops, and survives…

11. The Resource Base… The Resource Base People The Natural Environment The Built Environment The Industrial Base

12. …Which tends to be seen primarily as Economic Capital… Economic Capital The Built Environment Social Capital The Industrial Base Natural Capital

13. Specifically for the Built Environment, the A/E/C Industry is:

14. First, the interrelationships and interdependencies among its dimensions have unique characteristics…

15. Second, the multiple levels of perspectives on, complexity of, and scales of sustainability also have unique characteristics… Perspectives

16. INDIVIDUAL PROFESSIONAL ENTERPRISE INDUSTRY SOCIETY WORLD

17. Second, the multiple levels of perspectives on, complexity of, and scales of sustainability also have unique characteristics… Perspectives Complexity

18. TODAY 1 YEAR 1 – 5 YEARS 5 – 10 YEARS 10 – 25 YEARS 25 – 50 YEARS +

19. Third, the multiple influences on sustainability also have unique characteristics… Social, Cultural, Political, and Regulatory Systems Economic and Financial Systems Environmental and Ecological Systems

20. Which of these forms of Sustainability must/should/could/would we use in Latin America? Fourth, the lack of a unified theory of sustainability… Sustainability is currently expressed in multiple forms: –Frameworks –Models –Principles –Concepts –Heuristics –Strategies –Guidelines –Specifications –Standards –Processes/Tools –Best Practices –Lessons Learned…

Vorster)

23. Internal External SOURCE OF CHANGE ProactiveReactive ATTITUDE TOWARD CHANGE (Inspired by A. Pearce)...create triggers of change... Triggers are changes in: Values Mission Perceptions FLASH Triggers are changes of: Functional Requirements Physical Integrity /Function CRASH Triggers are changes caused by: Market Benchmarks Competition SPLASH Triggers are changes in: Codes Regulations Standards CLASH Regardless of the trigger, sustainability will inevitably force change, and how organizations respond will make them end… either with a Pile of CASH…or as a Pile of ASH…

24. ...stated in another way... “...You really- oughta-wanna...” “...You really- shoulda...” “...You really- gonna-hafta...” “...You really- gonna-wanna...” (Inspired by P. Melhus)
