Ralph DiNola gave a presentation on zero net energy buildings and constructive innovation at a conference in Fort Collins, Colorado. He defined zero net energy buildings as those that produce as much renewable energy as they consume annually. DiNola discussed the concept of disruptive innovation and how zero net energy goals in places like California are aiming to disrupt existing energy and building practices. The presentation provided examples of early zero net energy projects and discussed challenges and trends in the field, such as improving data collection and operational performance. DiNola closed by assigning attendees the task of advancing constructive innovation and zero net energy through new partnerships and policies.

- 16. Governor Brown’s Zero Net Energy Goals California has a set a bold course to achieve statewide Zero Net Energy (ZNE) in the next two decades: • All new residential construction will be ZNE by 2020 in California. • All new commercial construction will be ZNE by 2030. • 50% of existing commercial buildings in California will be retrofitted to ZNE by 2030.

- 21. Closing Session Feedback • ZNE buildings do not have to cost more • Shift the cost discussion to value • Stretch codes are the opportunity to ratchet up the built environment and compliance and O & M is critical • Prototypes are critical • Individuals influence NBI © 2013
- 22. Closing Session Feedback • The cache of ZNE is real, it is a tipping point • The value of aspirational goal, such as the 2030 which inspired CA. • The Grid is our friend, let’s not alienate the partner in the utility that we need to bring along on this pathway. • EcoDistricts are very inspiring and scale jumping. • Government needs to engage and demonstrate but also get out of the way and let innovation thrive. NBI © 2013
- 23. Closing Session Feedback • Setting the aspirational goal has led to a large range of policy efforts and ideas • Strategy we need next is the next level of how to monitor these buildings • The State and local government is where it is going to happen • So exciting to get together with so many experts, next we can build collaboratives. • Gary Christianson: small scale developer, was beginning to scale back efforts, now feels ZNE effort can continue and so very achievable.

- 34. Insights • ZNE offers a clear and aspirational target • It is hard - a process not a static outcome • High performance first – lower energy use lowers PV cost • Growth and opportunities in repeatable buildings (schools, banks, small offices) • District, community, campus level offer cost and scaling efficiencies • Actual ZNE happens downstream of design operational focus, tenant behavior focus NBI © 2013
- 35. Trends • Bigger buildings, more types, more firms, diverse climates, lower EUIs, • Buildings use readily available technologies and integrated design • Net Positive • Designers and owners want measurement and feedback • Design teams going beyond the project to policy • Low-rise Multifamily growing • Ultra-low energy accomplishments are accelerating Ramona Apartments, Portland, OR NBI © 2013
