With regard to the importance of these essential values, be it resolved that the U.S. Green Building Council adopts the following guiding principles:

1. PROMOTE THE TRIPLE BOTTOM LINE: USGBC will pursue robust triple bottom line solutions that clarify and strengthen a healthy and dynamic balance between environmental, social and economic prosperity.

2. ESTABLISH LEADERSHIP: USGBC will take responsibility for both revolutionary and evolutionary leadership by championing societal models that achieve a more robust triple bottom line.

3. RECONCILE HUMANITY WITH NATURE: USGBC will endeavor to create and restore harmony between human activities and natural systems.

4. MAINTAIN INTEGRITY: USGBC will be guided by the precautionary principle in utilizing technical and scientific data to protect, preserve, and restore the health of the global environment, ecosystems and species.

5. ENSURE INCLUSIVENESS: USGBC will ensure inclusive, interdisciplinary, democratic decision-making with the objective of building understanding and shared commitments toward a greater common good.

6. EXHIBIT TRANSPARENCY: USGBC shall strive for honesty, openness and transparency.

Sustainable - Triple Bottom Line

Ecology Equity

Regenerative

Only life, at all scales, has regenerative potential

Establishing a healthy relationship with nature instead of an adversarial relationship – to the mutual benefit of all life

Requires a major shift in our thinking (worldview)cooperation not competitionexperience not beliefcommunal not individualvalues not valueholistic not reductionist

Will life continue to degenerate?

Are we slowing down fast enough?

The Evolution of LEED

Market Transformationfacilitate positive results for the environment, occupant health and financial return

Define “green”provide a standard for measurement—common “brand” yardstick

Prevent “Greenwashing”flush out false or exaggerated claims

Integrate Disciplinespromote whole-building--integrated design processes

Promote Competitionreward leaders and promote good models

Why was LEED created?

The market has caught up.(faster than we thought)

Isn’t that what we wanted?(yes and no)

LEED still needs some work.(its intent is too often circumvented)

INTEGRATIVE PROCESS

Highlights the importance of iterative, inclusionary process in the design, construction, and operations of green projects

Applicable rating systems: BD&C ID&C EB:O&M ND

Intent

Develop an early understanding of the relationships between technical systems, natural systems and occupants within a building project, its site, its context, and its intended use. Engage all key project team members for the purpose of making cost-and environmentally-effective integrated decisions throughout the design and construction process.

PERFORMANCE

Highlights the importance of on-going operational performance in LEED Projects

Credits in this category deal with performance measurement and verification.

“Regenerative”

Product performance EPD basis; revised Impact categories & weightings (every cycle); incorporate Social Equity as an Impact category; introduce absolute performance metrics for Energy, Water, Waste, IEQ.

Dynamic (place-based) scorecard; LCA-based credits instead of single-attribute materials tools; product certification EPD must be 3rd party verified; incorporate Social Credits; require absolute performance metrics for Energy, Water, Waste, IEQ; revised Impact categories & weightings (every cycle).

Integrate buildings and ND ratings; true LCA for materials; Zero Net (Energy, Water, Waste) performance threshold for Platinum; revised Impact categories & weightings (every cycle).

Zero Net (Energy, Water, Waste) performance threshold for Gold; revised Impact categories & weightings (every cycle).

Zero Net (Energy, Water, Waste) performance threshold for Silver; revised Impact categories & weightings (every cycle).

Zero Net (Energy, Water, Waste) performance threshold for Certified.
