5 Understanding ZNE Owners Ideological Motivation Institutional Mandates Green Market Competition

6 Convene Leadership and Set Goals Use appropriate metrics to communicate goals and measure success Energy, Cost, GHG emissions Percent improvement versus absolute goal Consider non-energy benefits as articulated by the $3 (utilities), $30 (rent), $300 (payroll) rule newbuildings.org/code_policy/zepi/

7 OVERCOMING THE COST BARRIER The prevailing industry perception is that zero energy is cost prohibitive and suitable only for showcase projects with atypical, large budgets; however, there is mounting evidence that zero energy can, in many cases, be achieved within typical construction budgets.

8 Life Cycle Cost Analysis - LCCA What is the full price of a building? Life Cycle Cost = Net Present Value of: - First Costs (hard and soft) - Utility Costs - Ongoing Maintenance -Repair/Replacement - Residual Value New Buildings Institute, 2015

9 Fundraising & Financing Strategies 1. 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

10 Fundraising & Financing Strategies 9. 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

11 Different Markets Commercial Real Estate Municipal University School Hospital

12 Matching the Market Commercial Real Estate Characteristics: Generally Tenant-Occupied Split Incentives Higher Tenant Turnover Investment funding

13 Matching the Market Commercial Real Estate Considerations: More building life-cycle opportunities Staged projects are more likely Market factors are more likely to dominate

14 Matching the Market Municipal University School Characteristics: Generally Owner-Occupied Institutional Funding Institutional Decision Making Hospital

15 Matching the Market Municipal University School Hospital Considerations: One-shot projects are more likely Operating expenses are more likely to motivate More likely to have sustainability mandates

16 Interventions Low intervention: Remote Audit Retro-commissioning Most Luminaire Upgrades Controls Tuning / Upgrade Plug Load Savings/Policy Operator and Occupant Training Some Infiltration Reduction Measures Medium intervention: Lighting System Replacement/Reconfi gure HVAC Equipment Upgrades Controls: System Upgrade Opportunistic Envelope Insulation High intervention: HVAC System Switching Envelope Upgrade Window Replacement Renewable Energy System
