  3. 3. Program Initiative: Strategic Plan• Long term Strategic Plan (PlaNYC) – Initiated Earth Day, 2007; Mayor Blumberg – Green Energy; reduce greenhouse gas emissions by 30% in full by 2030 (from 2005 baseline) – Improve the environment – Improve Quality of life© 2011, The Sanborn Map Company, Inc.

  4. 4. Program Initiative: Solar Energy• NYC Greener, Greater Buildings Plan – Electricity, heating and hot water consumed in buildings accounts for 75-80% of the greenhouse gas footprint – Energy Savings – US Green Building Council (LEED Guidelines) • Water Efficiency • Improve interior building environmental quality • Energy Savings • Future; Develop ‘passive survivability’ • Portion of the Plan implements Solar Energy© 2011, The Sanborn Map Company, Inc.

  5. 5. Stakeholders These are the four project partners that are  working on the SOLAR NYC Project.  These  partners have signed an MOU outlining  specific roles and responsibilities.  Mayor’s Office of Long-Term PlanningSustainable CUNY on behalf and Sustainabilityof the City University of NewYork Hunter College - CUNY NYC Solar America Cities Advisory Board • Eight industry representatives • Ten non-profit solar/energy advocacy organizations • Six additional government We work with these City agencies on  agencies various solar initiatives.  They provide Our utility and state partners.  These groups  expertise on how to integrate solar into provide financial and advisory support.   their processes and programs.  © 2011, The Sanborn Map Company, Inc.
