Building Envelope Upgrades

Our experience has shown a shift away from large scale solar projects to energy efficiency projects. We are flexible enough to change with market factors compared to solar only companies.

Our Secret Sauce – Case Study

• Option 1 – Solar Only Approach• Energy Savings: $10,000 per year

• Total Project Cost: $74,000

• Project Components: 16kW Solar System

• Option 2 – Whole Building Approach• Energy Savings: $10,000 per year

• Total Project Cost: $60,000

• Project Components: 10kw Solar System, Full Building LED Lighting Retrofit, Central Building Monitoring and Controls.

PAST

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

PRESENT

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

How are we different 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)

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

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

KEYS GARAGE BI-LEVEL LED

Modernizing FacilitiesDublin 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.

FUTURE

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

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

The Big Players UnderstandClay 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.”
