  • USGBC started in 1992. Now is the fastest growing non profit in the world- over 25,000 organizational members.100,000 LEED APs.LEED is the accepted premiere standard of Green Building in the world today.
  • New Construction 2.2 is now being offered in a new version.Neighborhood Development is in the preliminary stages of design.
  • By using efficient technology in combination with the best ofproven passive solar features, the zerocarbon home outperforms without getting complicated.Typical features include ground-source heat pumps, ultra efficient lighting and appliances, super insulated walls, floors and roofs, solarhot water pre-heat systems and solar photovoltaic power integrated into the roof design.
  • Green building codes, programs & rating systems

    1. 1. GREEN BUILDING CODES, PROGRAMS & RATING SYSTEMS<br />
    2. 2. California Climate Policy<br />AB32 “California Global Warming Solutions Act”<br />Reduce CA Greenhouse Gas Emissions to 1990 Levels by 2020<br />CEC, CPUC to require (Title 24):<br />All new residential construction zero net energy by 2020<br />All new commercial construction zero net energy by 2030<br />

Lifecycle of Buildings - Think in Terms of Flow<br />Development Center for Appropriate Technology - 2009<br />Materials<br />Energy<br />Water<br />Money<br />Air<br />Site<br />Waste<br />Heat &<br />Light<br />Waste <br />Water<br />Wasted<br />Money<br />Material<br />Waste<br />Pollution<br />
    6. 6. Big Problems Hidden in Plain View<br />Looking at buildings through <br />codes has been like looking <br />through a microscope, with <br />individual building-related risks <br />filling the field of view. <br />Beyond this limited scope of <br />concern are much greater<br />generalized risks for everyone <br />and future generations that <br />can't be seen through that lens. <br />Development Center for Appropriate Technology - 2009<br />
    7. 7. Development Center for Appropriate Technology - 2008<br />Risk - The Bigger Picture…<br />Risk - Through the Microscope of Codes…<br />Risks to Future Generations<br />Climate Impact<br />Resource Depletion<br />Fire Safety<br />Structural Integrity<br />Means of Egress<br />Light<br />Ventilation<br />Heat<br />Water & Wastewater<br />Electrical & Gas<br />Energy Efficiency<br />Fire Safety<br />Structural Integrity<br />Means of Egress<br />Light<br />Ventilation<br />Heat<br />Water & Wastewater<br />Electrical & Gas<br />Energy Efficiency<br />Dependence on Non-Renewable Energy<br />Embodied Energy<br />Pollution<br />Loss of Habitat<br />Loss of Biodiversity<br />Toxicity of Materials<br />Nutrification of Water<br />Loss of Agricultural Land<br />Increased Transportation<br />Heat Island Effect<br />Externalized Costs to Society<br />
    8. 8. Risk - The Bigger Picture…<br />Development Center for Appropriate Technology - 2009<br />
    9. 9. Risk - We Need to Balance them All…<br />
    10. 10. Huge Risks are <br />Falling Through the Cracks…<br />Development Center for Appropriate Technology - 2009<br />
    11. 11. The Current Situation…<br />Typically we have a maze of regulations & agencies, with jurisdictional levels, and differing goals and standards. <br />The gaps externalize risks to the future and to the commons. The overlaps complicate enforcement, and often allow each agency to avoid full responsibility.<br />Development Center for Appropriate Technology - 2009<br />
    12. 12. The Current Situation…<br />Regulations are reactions to serious, persistent<br />problems requiring official action. We don't get them<br />when problems are small, manageable or avoidable. <br />We haven't designed in a forward-looking capability<br />to address emergent risks or new kinds of risk...<br />so the main navigational <br />tool in the regulatory arena <br />is the rear view mirror…<br />Development Center for Appropriate Technology - 2009<br />
    13. 13. These are Questions to Be Addressed<br />What Risk?<br />Where?<br />To Whom?<br />When? <br />How Long?<br />How?<br />How Much? <br />Is It Reversible? <br />Is It Necessary?<br />At What Cost<br />and to Whom? <br />(not just monetary)<br />Development Center for Appropriate Technology - 2009<br />
    14. 14. Appropriate Technology<br />The lowest or simplest level of technology that can do the job well…<br />And that doesn't make people or their communities dependent on systems over which they have no control. <br />Development Center for Appropriate Technology - 2009<br />
    15. 15. Responsibility for Unintended Consequences<br />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.<br />Development Center for Appropriate Technology - 2009<br />
    16. 16. Rethinking Long-Standing Assumptions<br /> Traditional, non-industrial materials & building systems were rejected because of labor-intensity not because they're inferior or dangerous.<br />Lack of support for research, testing, and the development of standards makes it hard to gain approval for their use.<br />Development Center for Appropriate Technology - 2009<br />
    17. 17. Life Cycle Assessment<br />
    18. 18. California Green Building Code<br />Chapter 1 – <br />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.<br />
    19. 19. CA GBC<br />Section 101.7<br />….view these standards as minimal Green Building Standards and that local government entities retain their discretion to exceed the standards established by this code.<br />
    20. 20. How does the CA GBC work?<br />The CA GBC is a collection of green building <br />“best practices.” <br />It does NOT determine if a building is green.<br />It is NOT a rating system. <br />
    21. 21. Green building Rating Systems<br />LEED<br />Green Point Rated<br />One Planet<br />2030 Architecture Challenge<br />
