  1. Meet the DBI Pros SummitOctober 11 & 12, 2007 Isam Hasenin,P.E., C.B.O., DIRECTOR Green Buildings Solar Systems

  2. Moderators David Green, Senior Electrical Inspector Department of Building Inspection • Richard Chien, Residential Green Building Coordinator, Department of the Environment

  3. Green Buildings and Solar Systems Overview • Why Green Buildings? • Federal Programs • State Programs • City Green Building Initiatives • Steps residents can take to reduce energy used in their home • Photovoltaic system permit process

  4. Why Green? • The level of Carbon Dioxide in the atmosphere is increasing and causing global warming • Global warming is causing environmental effects including an increase in sea level • Too rapid an increase in sea level can cause tremendous damage to infrastructure in coastal areas

  5. We can make a difference • Reduction in CO2 production can delay sea level rise and give us more time to respond and relocate as needed • Use of renewable and sustainable resources protects the environment

  6. U S Department of Energy • http://www.energy.gov/index.htmhttp://www.energysavers.gov/ • ENERGY STAR • The government-backed symbol for energy efficiency • Energy Savers: Tips • Energy-saving tips, ideas and solutions • Energy Calculators & Software • Calculate your energy costs

  7. California Solar Initiative A California Public Utilities Commission 10-year, $2.9-billion program The goal is to increase the amount of installed solar capacity on rooftops in the state by 3,000 megawatts by 2017.

  8. San Francisco Initiatives • 1997 Sustainability Plan • 2002 Climate Action Plan • 2004 Municipal Buildings LEED Silver • 2004 Zero Waste Goals set • 2005 Mayor Newsom signed Urban Environmental Accords • 2006 DBI Solar PV permit processing • 2006 DBI Green Building Priority Processing

  9. DBI Programs • PRIORITY PERMIT PROCESSING FOR GREEN BUILDINGS, Contact Laurence Kornfield, Technical Services Division 558-6244 • OVER-THE COUNTER, LOW-COST PERMITS FOR SOLAR PHOTOVOLTAIC ELECTRICAL SYSTEMS.Contact David Green, Electrical Inspection Division 558-6654

  10. CaliforniaEnergy Code DBI is required to enforce • DBI enforces this code through plan review by the Mechanical Plan Review Section, and by the field inspection process • New construction and renovations are required to be highly energy-efficient

  11. California Energy Code Requirements • Electric resistance space heating and electric resistance water heating are prohibited

  12. California Energy Code Requirements • Furnaces, heat pumps and air conditioners are required to be energy efficient types

  13. California Energy Code Requirements • Window area is regulated and residential windows are required to be energy efficient

  14. California Energy Code Requirements • All new replaced or modified residential light fixtures shall be “high efficacy” type with exceptions.
