Policy leaders are setting resolute goals and plans to cut energy and reduce carbon emissions. In response business investments are accelerating around a new clean energy economy. But what is the risk for disadvantaged communities that are not able to actively participate? This plenary session examines the need to advance investment that supports economic growth through research and development as well as provide healthy community development.  Our keynote speakers will showcase the importance of financial standards that deliver on economic growth with reducing climate impacts and also spotlight the systems-level thinking that can provide equitable solutions that are beneficial to all.

Policy and Legislative Drivers for Decarbonization in California (1.5 AIA LU|HSW CEUs)
Room: Junior Ballroom 1
Building decarbonization is an emerging solution to address statewide greenhouse gas reduction goals.  This session looks at key legislative, regulatory, and gubernatorial initiatives driving decarbonization in California, including the roles of the state agencies involved.  What role will the state’s energy code for buildings have driving energy efficiency and decarbonization, including the important prospective roles for local governments around local “reach” codes?  Multiple scenarios involving varying rates of decarbonization, and how those scenarios impact emissions footprints over time will be discussed.

Busting the Cost Barrier of Zero through Smart Finance and Collaboration (1.5 AIA LU|HSW CEUs)
Room: OCC 210/211
Cost is the number one perceived barrier to zero energy projects even though many have been able to achieve success at no additional cost. Learn how ultra-low energy buildings combined with on-site renewables, and energy storage impacts energy savings, long-term project value, and financing decisions. Experts will show how they evaluate various financial instruments for zero energy buildings and associated solar and storage installations. Understand the crucial issues when gauging financing options, including tax-exempt leases, sale-leaseback, partnership-flip, and cash purchase scenarios.

Policies on Embodied Carbon (1.5 AIA LU|HSW CEUs)
Room: OCC 208
Government policies to limit carbon emissions from the building sector have historically focused on energy use. However, energy-related operational carbon is only part of the total carbon emitted over a building’s lifecycle. Increasingly, governments are recognizing that they also have policy options to limit embodied carbon related to building materials and construction. These can take different forms, such as limiting emissions from specific high-impact materials, requiring whole building lifecycle analysis, or zero carbon certification that includes embodied carbon. A range of policy case studies will be presented, along with a discussion about the pros and cons of each approach.

GridOptimal: Connecting Electric Grid Needs with Building Opportunities to Stabilize and Decarbonize the Grid (1.5 AIA LU|HSW CEUs)
Room: Uptown
The modern electric grid working to evolve as the historic grid infrastructure strains to handle the growing number of distributed energy resources and smart systems. Experts looking at ways to design buildings for grid-optimal performance are using modeling analysis that layers ever-shifting carbon intensity and grid demand over the hourly annual energy model in order to understand the actual time-based carbon emissions of a building. Learn about a new metric for GridOptimal Buildings that offers energy flexibility in buildings, which can be leveraged as a carbon reduction strategy. Presenters will show how GridOptimal was applied at Sonoma Clean Power (SCP) Headquarters to demonstrate both decarbonization and grid harmonization strategies into the building design.

Decarbonization and the Grid: Impacts and Issues (1.5 AIA LU|HSW CEUs)
Room: Junior Ballroom 1
California’s decarbonization goals impact electric and gas infrastructure by increasing electric demand and reducing gas use, potentially increasing costs for utilities.  As more all electric buildings emerge and the electric demand grows, utility operators are seeking to incentivize building load flexibility in order to support healthy grid operations, including aligning energy generation and building energy demand. This session will review the high-level needs of the energy transmission and distribution systems and probe the impact of building energy load demands on grid investment requirements.  Presenters will also discuss how issues around gas infrastructure costs and cost recovery under various scenarios  including greater and lesser amounts of natural gas and renewable gas throughput.

Driving Innovation to Reduce Costs in Affordable Housing (1.5 AIA LU|HSW CEUs)
Room: Uptown
Affordable housing developers are a natural fit to get buildings to zero because of their long view on investment, mission, and history of progressive leadership. However, affordable housing faces intense financial and public pressures to “maximize unit count,” which sometimes limits benefits to occupants. Scaling low-energy, affordable housing requires collaboration between foundations, utilities, local jurisdictions, banks, and impact investors to provide the necessary funding that catalyzes action. Speakers will share strategies for maximize housing units while reducing energy use and carbon emissions, as well as the tools and scalable solutions that are transforming affordable housing development.
