2016 ZNE For Local Governments Workshop | Santa Monica, CA
Why ZNE?• Innovation & Leadership - Zero
energy buildings present importantleadership and commitment to thepublic, as well as responsibility inwise use of energy resources, andinnovation of what can be done in thebuilt environment.
• Resiliency – Government facilitiesoften serve as community centers forrefuge in times of emergency;
• Long Term Savings in efficiency,cost, operations, climate
• Alignment with Policy Goals –Local Climate Action Plans, StateEnergy Efficiency Strategic Plangoals
ZNE for Local Governments
When government leads,the people will follow…

2016 ZNE For Local Governments Workshop | Santa Monica, CA
Motivations to Pursue ZNE• State Policy/Executive Order• Stabilize energy costs and lower GHG• Renewable Energy Goals• Leadership & demonstration• Help promote ZNE to professional
design community and owners• Building project in progress with high
performance goals• Increasing uncertainty about cost and
availability of energy, risk managementfor financing operations and long termsustainability
“There is increasinguncertainty about thecost and availability ofpurchased energy tooperate existing andnew facilities. Theseuncertainties pose risksto institutional finances,operations and long-term sustainability.”

2016 ZNE For Local Governments Workshop | Santa Monica, CA
Strategies:• Engage leadership to set ZNE
Goals & Targets• Adopt a formal policy for ZNE• Establish a ZNE Task Force• Solicit Feasibility Studies for
Capital Projects• Initiate one or more ZNE Pilots• Amend contract RFP/RFQ
Requirements for ZNEperformance goals and priorities:for contractors, performancetargets, required specifications,documentation and persistence
ZNE for Local Governments

2016 ZNE For Local Governments Workshop | Santa Monica, CA
Strategies:• Piloting ZNE projects• Community building renewal (assessing existing local building
stock to find opportunities).• Look at what is coming up for capital improvement projects and
pilot or upgrade systems and structures to get to ZNE.• Consider DMV’s approach to pursue ZNE on all new projects
now and skip the pilots.• Resiliency Planning - Identify “critical facilities” as priority
projects; pair up with FEMA or other hazard mitigation funding• Demonstration of leadership in building technologies
How are Local Gov doing ZNE?

What Buildings Make Sense for ZNE?Most Building Types are feasible• Low-Mid-Rise Office Buildings• Service Buildings• Warehouses• City Halls• Recreation & Environmental Centers• Libraries• Low Occupancy Buildings/Facilities
Priority Buildings• New buildings/campuses• Buildings needing major replacement,
big energy hogs, buildings wheresystems are needing major retrofits

Strategies:1. Explore creative funding opportunities for ZNE: EPIC,
Savings by Design, technology demonstration, bonds,establish efficiency reserve funds.
2. Establish Incentives for ZNE buildings: permitting fasttrack, fee waivers, low cost loans, public recognition byleadership, etc.
3. Use the Tools to Engage and Educate internal staff,leadership and public facing staff, communication and mediare: goals, targets, and important roll in operations andbehavior
4. Educate facilities and operations staff – much of ZNEhappens downstream

OVERCOMINGTHE COSTBARRIER“The prevailing industryperception is that zero energy iscost prohibitive and suitable onlyfor showcase projects withatypical, large budgets; however,there is mounting evidence thatzero energy can, in many cases,be achieved within typicalconstruction budgets.”

2016 ZNE For Local Governments Workshop | Santa Monica, CA
Fundraising & Financing Strategies1. Utility Program Support - Savings By
Design
2. Pilot Research Program
3. Technology Demonstrations
4. Use an Upgradable Design Strategy
(e.g. Redding School for the Arts)
5. External Grant Funding
6. District Approach to Energy (FortZED)
7. Solar Financing District (e.g PACE)
8. Prop 39 funding for schools

2016 ZNE For Local Governments Workshop | Santa Monica, CA
Fundraising & Financing Strategies9. Prototypical Design for replication of standard
buildings (Campbell School District’s 8 new
schools)
10. Reduction of operation costs = increased
capital project budgets
11. Power purchase agreements (PPAs)
12. Energy Service Companies (ESCo)
13. Emerging Tech programs through utilities
14. Urban development tools (if they are in local
government redevelopment area)
15. FEMA or hazard mitigation financing for
resiliency planning and critical building upgrades
