3. Hire the right team!
4. Set goals with the WHOLE team
5. Establish measurable goals and track through design into
operation
6. Earn 1 LEED point vs. Revolutionary Results
Credit Intent
To support high-performance, cost-effective project
outcomes through an early analysis of the
interrelationships among systems.
Credit Requirements
The credit requires both early-stage “discovery” analysis
and later-stage “implementation” steps for both
energy- and water-related systems.

WATER-RELATED COMPONENTS
240 Stockton—
San Francisco
Two-story TI
o worked with the facility manager
o “discovered” a large roof area available for rainwater
catchment
o large existing water tanks in the basement that were
slated for demo that could function as cisterns
Willow School—
New Jersey
New Construction
o Onsite storm water treatment, originally refused and
later embraced
Garden Village Apartments—Berkeley
Rooftop farm
o Seed production requires significantly less water and provides a product of higher dollar value
UC Santa Cruz
Haybarn—
Santa Cruz
Historic Renovation
o Cost of new water line versus rainwater and existing
cistern that had been slated for demo
SITE SELECTION
Garden Village Apartments—Berkeley
Switching from net zero to Rooftop farm
o Deeper discovery uncovered passion for and value of locally grown food
o Entitlement assistance - Parking requirement elimination to Car Share
UC Santa Cruz
Haybarn—
Santa Cruz
Deeper Green
o Identified additional funding for enhanced vision
from LEED to LBC
Zero Net Energy Center—San Leandro
Existing educational facility renovation
o Computerized modeling revealed synergies of roof penetrations with improved indoor learning
environment + drastic energy reductions
• Express your passion, discovering human assets
• Cross-disciplinary and horizontal working
• Invite creativity and cross-disciplinary thinking
• Focus on thriving rather than risk avoidance
• “What can we not do?” Install utilities?
• “The unasked question never gets answered”
• Sticky board – collective agreement - not allowing
it to creep
• Our impact on the land should leave it in better shape than we
found it for all stake holders. This project serves as part of a
larger ecosystem upon which it also depends.
• Leave our egos at the door
• Elicit, establish and embed commonly held key project concepts
while also avoiding Group Think
• Look beyond the property lines (Site, Existing buildings, facilities
& infrastructure, Neighbors, Partnerships, Climate, Indigenous
materials, Subsidies)
• Blue sky session – only positive responses
