20161020_ASA Beyond The Panel (1)

  1. 1. Beyond the Panel Looking at PV in a Different Light What Could the Future Look Like? Christopher Klinga, PE Technical Director October 21, 2016
  2. 2. Our Mission Architectural Solar Association (ASA) is an industry advocate for standards development, education, legislative regulations, building & energy codes and solar architecture design specification as they relate to integrating solar into the architectural envelope. We represent a growing industry with a common goal of transforming building facades and other architectural surfaces into generating assets. •
  3. 3. Objectives Standard Development UL 1703 is a major barrier to integrating solar with the building envelope. Changes in codes and standards are the first step in widespread adoption. Demand Creation There is currently far too much uncertainty in the tax code and how to establish effective financing mechanisms for architectural solar installations. ASA looks to develop ways to break down this uncertainty through various mechanisms. Building Industry Adoption The US building industry and the solar industry have yet to fully integrate. Solar needs to be a ubiquitous resource to all building professionals. ASA looks to make that possible. •
  4. 4. Overview • Definition of BIPV • Architectural Integration Opportunities • Benefits and Trends of Architectural Solar • Commercially Available Solutions • The Future of PV in Architecture
  5. 5. BIPV PV with Architectural Significance BIPV shall be defined as a photovoltaic generating component which forms an integral and essential part of a permanent building structure without which a non-BIPV building material or component would be required to replace it. The performance of power generation by a BIPV component is deemed to be secondary to the role of being a building material or structural component. BIPV occupies a space in the building design such that, if removed from that space, its absence will be distinct and noticeable.
  6. 6. Why is the Market Ready for BIPV? • Technology Advancements • Steep $/W cost reductions • Higher efficiency per unit area • PV solar has reached grid parity Compelling BIPV Economics • Competitive IGU COGS • Compelling payback • ITC credits & MACRS • Higher lease rates and velocity Trending Tail Winds • Government BIPV Regulations • Net Zero Buildings • Green Building Incentives • Strong Desire for Sustainability

  8. 8. BIPV Benefits • Increases distributed energy generation potential. • Capable of serving multiple design intents. • Visually & Functionally • Capable of reducing cooling load through shading. • Manufacturing and installation costs can be analyzed on an incremental level.
  9. 9. Compelling Economics • Ballpark Curtain Wall Construction “Price” • $80-$120 per sq ft • IGUs Price – $10-$15 per sqft • PV Threshold for Tax Credit Parity • $2.45 per watt PV @ 15% Efficiency = ~$34 per sq ft • BIPV Curtain Wall System @ 15% Efficiency • $104 – $154 per sq ft • Post 30% Federal Tax Credit Price • $80-$108 per sq ft

  11. 11. Benefits • Solaria Cell Processing • PVIGUs – Photovoltaic Insulated Glass Units • Reduced Solar Heat Gain Coefficient • Options to tailor transmittance • Spandrel and Façade Area Integration • Large surface area potential • Louvers & Sun Shade Integration • Increase the useable building footprint while reducing cooling load Trends in Architectural Solar

  14. 14. So what could the future look like? Architectural Solar holds the promise of being highly suitable for the built environment. The variation in products and integration possibilities could result in aesthetically superior buildings with greater functionality. From a technical perspective, the production process is reduced in comparison to commodity solar solutions. The savings in construction time and material together with the improved aesthetics will contribute to the success of BIPV. The final and most important step will be to effectively integrate solar solutions into the complete value chain of the building industry.
