6. PAST

7. Past Approach
• Going Green is “Too Expensive”
• No Budget for It.
• Single Trade Focus
• Limited Rebates by California and DOE
• Little to No Regulation on Energy
Standards

9. PRESENT

10. Filling the Void Today
Combining Simple Energy Efficiency
Measures with Solar Power
Leasing Alternatives
Local & State Rebate
Energy Engineering (Peak Demand)
Balancing Modernization with Going Green
Partnering with CM’s, Architects, Engineers,
Consultants

11. How are wedifferent from Solar City?
Solar City:
• No HOA’s or Non-Profits
• No Energy Efficiency Focus
• Aggressive Sales Rep Based
• All About the Lease
• Most Solar Companies
ESCO Approach:
• Make the building more efficient before doing any solar
• Develop a project plan that integrates rebates and lifecycle
maintenance costs
• Partner with CM’s, Architects and PM’s to develop win win projects
• SHOW CLIENT THE MONEY (Finance driven projects)

12. Pay with Savings Approach
Annual Energy Savings: ~$40,000
Annual Loan Payment: $36,000
Cash Flow Year 1 to HOA: +$4000
40kW Solar Project and Energy Retrofit for a 75 Unit Community
Project Cost: $225,000
Typical Terms: 6 -10 Years
4.5%-5.5% Interest Rate

13. REBATES
• Rebates and Tax Credits are industry specific
• Multi-Family
• Commercial
• Residential
• Rebates are geographic specific
• SF/SAN MATEO/EAST BAY Energy Watch
• Marin Clean Energy
• Silicon Valley Power
• Rebates need detailed Energy Modeling
• HERS/BUILD I T GREEN/RESNET/ MORE!
• Test in Test Out

16. Modernizing Facilities
Dublin Ranch Golf Community – Dublin,Ca 1400+ SFH
• Size: 400 units – Single Family Community
• Electrical Costs Current: $24,000+ (Pool Meter)
• Electrical Savings: $20,000 per year
• Challenges: Pool deck too hot in summer, electrical costs
increased 6% because of peak demand pricing, pro-active
board
• Solutions: Custom designed steel trellis system with
integrated solar pv, LED bollards.
• Result: Allowed for huge increase in the amount of residents
using the pool.

25. FUTURE

26. Future Focus
• “Greening of the Construction Industry” – everything is going
green. The best companies will be the ones who figure out
how to sell green products to their existing customers.
• Positive Cash Flow Projects or “Pay with Savings” Projects will
be the preferred method of delivery for energy efficiency
projects.
• EROEI = Energy Returned on Energy Invested

27. PARKWOODS HOA
• OAKLAND,CA – 300+ UNITS
• 3 FOCUSES
• MODERNIZE AND UPGRADE BUILDINGS TO TODAYS STANDARDS
• IMPROVE SAFETY FOR COMMUNITY
• REDUCE MAINTENANCE AND LIFECYCLE COSTS
• PROJECT CONCEPT
• PHASE APPROACH
• FIRE SPRINKLER UPGRADE (COMPLETED)
• INTEGRATE SOLAR STANCHIONS WITH NEW ROOF (2015)
• COMPLETE BI-LEVEL LED LIGHTING RETROFIT FOR SAFETY (2015)
• LEED CERTIFICATION FOR BUILDING VALUE (2016) & WATER SAVING
MEASURES (2016)
• PAY WITH SAVINGS APPROACH

29. The Big Players Understand
Clay Nesler, VP of global energy and sustainability, Johnson Controls:
“In our 2013 global survey of 3,000 facility and energy management
executives, we found that 73 percent of organizations had made
internal or public goals to reduce energy consumption. We also found
that organizations that made public goals implemented 50 percent
more efficiency measures last year and were 2.7 times more likely to
increase investments next year than organizations without goals.”
