6. Big Problems Hidden in Plain View
Looking at buildings through
codes has been like looking
through a microscope, with
individual building-related risks
filling the field of view.
Beyond this limited scope of
concern are much greater
generalized risks for everyone
and future generations that
can't be seen through that lens.

9. Risk - We Need to Balance them All
10. Huge Risks are
Falling Through the Cracks
Development Center for Appropriate Technology - 2009
11. The Current Situation
Typically we have a maze of regulations & agencies, with jurisdictional levels, and differing goals and standards.
The gaps externalize risks to the future and to the commons. The overlaps complicate enforcement, and often allow each agency to avoid full responsibility.
Development Center for Appropriate Technology - 2009
12. The Current Situation
Regulations are reactions to serious, persistent
problems requiring official action. We don't get them
when problems are small, manageable or avoidable.
We haven't designed in a forward-looking capability
to address emergent risks or new kinds of risk...
so the main navigational
tool in the regulatory arena
is the rear view mirror
Development Center for Appropriate Technology - 2009
13. These are Questions to Be Addressed
What Risk?
Where?
To Whom?
When?
How Long?
How?
How Much?
Is It Reversible?
Is It Necessary?
At What Cost
and to Whom?
(not just monetary)

14. Appropriate Technology
The lowest or simplest level of technology that can do the job well
And that doesn't make people or their communities dependent on systems over which they have no control.
Development Center for Appropriate Technology - 2009
15. Responsibility for Unintended Consequences
Doing things as locally as possible, as simply as possible, and doing as little as possible of those things that we know are harmful or about which our knowledge and understanding is limited.
Development Center for Appropriate Technology - 2009
16. Rethinking Long-Standing Assumptions
Traditional, non-industrial materials & building systems were rejected because of labor-intensity not because they're inferior or dangerous.
Lack of support for research, testing, and the development of standards makes it hard to gain approval for their use.

17. Life Cycle Assessment
18. California Green Building Code
Chapter 1
101.2 Purpose establishes the CA GBC as a means to improve public health, safety and general welfare by .building concepts having a positive environmental impact and encouraging sustainable construction practices.
19. CA GBC
Section 101.7
.view these standards as minimal Green Building Standards and that local government entities retain their discretion to exceed the standards established by this code.
20. How does the CA GBC work?
The CA GBC is a collection of green building
best practices.
It does NOT determine if a building is green.
It is NOT a rating system.
21. Green building Rating Systems
