  1. New Green Buildings and Energy-Efficient Retrofits John Morrill & Joan Kelsch Arlington County Government MWCOG Energy & Air Quality Conference, April 5, 2004

  2. Opportunities in three areas Green buildings for County gov’t Green building incentives for private developers Energy-efficiency improvements in existing buildings

  3. Voluntary certification program by the U.S. Green Building Council A leading-edge system for designing, constructing, and certifying the world’s greenest buildings. Arlington, Morrill & Kelsch, MWCOG, April 5, 2004

  4. LEED defines ‘green’ (1) Minimum standards (prerequisites) plus points awarded for smart choices in: site selection  materials & resources water efficiency  energy/atmosphere indoor environmental quality  innovation

  5. LEED defines ‘green’ (2) Points (credits) required for certification: Certified: 26-32 credits Silver: 33-38 credits Gold: 39-51 credits Platinum: 52-69 credits

  6. LEED defines ‘green’ (3)Energy & atmosphere credits are prominent Significant prerequisites (commissioning, CFC reduction, energy performance) plus 17 additional credits available for: further improvements in energy efficiency, use of renewable energy and green power, ozone protection, add’l commissioning, on-going measurement & verification

  7. Leadership in Energy and Environmental Design (LEED) Arlington built Virginia’s first LEED certified building, the Langston-Brown High School and Community Center. This is a LEED Silver project.

  8. Langston-Brown School & Community Center 50,000 sf replacement of 23,500 sf bldg Demolition waste diverted for recycling, rather than landfill Stormwater management including cisterns, porous pavement, bioretention, and stormceptor Extensive daylighting, light shelves, solar shading for energy benefits

  9. Green Building Programs for Private Development • Require LEED Scorecard submission • Require LEED professional and specific number of LEED credits • Green building density incentive • Green Building Fund contribution Arlington, Morrill & Kelsch, MWCOG, April 5, 2004

  10. LEED Scorecard for Development Projects • For projects not seeking USGBC certification: • Each project team must include a LEED- accredited professional • Each project must include the LEED Scorecard listing specific “green” components of the project, with explanation of each credit • County negotiates final LEED credits with applicant Arlington, Morrill & Kelsch, MWCOG, April 5, 2004

  11. LEED Scorecard for Development Projects • Specific number of LEED credits req’d (usually 15-20) • LEED Reports due at specific permit applications • If LEED requirements not met, County withholds permits Arlington, Morrill & Kelsch, MWCOG, April 5, 2004

  12. Green Building Incentive Program • Developer can apply for bonus density if project meets LEED requirements • Includes all types of building (not just commercial office) • FAR bonus offered ranges from .15 for Certified to .35 for Gold/Platinum Arlington, Morrill & Kelsch, MWCOG, April 5, 2004

  13. Green Building Incentive Program • Enforcement • Developer posts a bond that is released when the USGBC issues certification • If the project does not meet the certification, bond is forfeited to the County Arlington, Morrill & Kelsch, MWCOG, April 5, 2004

  14. Green Building Incentive Program Participants • Navy League Building is now under construction at 2300 Wilson Blvd 10,000 additional square feet • National Rural Electric Cooperative Association (NRECA) building recently approved in Ballston 16,000 additional square feet Arlington, Morrill & Kelsch, MWCOG, April 5, 2004

  15. Green Building Fund • If developer does not apply for LEED certification from USGBC, the project contributes to Arlington’s Green Building Fund • Contribution equals 3 cents/square foot 200,000 sq ft building contributes $6,000 • Fund to be used for green building education and outreach Arlington, Morrill & Kelsch, MWCOG, April 5, 2004

  16. Energy efficiency improvements to existing buildings (1) Changes in energy use from 1999 to 2003 - Central Library: electricity  30% Argus House: electricity  32% Solid waste/Traffic admin: electricity  14% Madison Comm. Ctr: gas  13% electric  17% Lubber Run Comm. Ctr: gas  26% elec.  19% Residential Program Ctr: gas  9% elec.  11%

  17. Energy efficiency improvements to existing buildings (2)

  18. Energy efficiency improvements to existing buildings (3)

  19. Energy efficiency improvements to existing buildings (4) Improved operation & maintenance Lighting retrofits Energy Star equipment Employee education (modest amt so far) In-house staff and contractors so far Large potential savings remain

  20. Importance of paying attention to both new construction and existing stock 1999 - Arlington government had 50 occupied buildings totaling 1.49 million sf, using 25.4 million kWh per year 2003 - those same 50 buildings used 9.6% less electricity (saving 2.4 million kWh) During 1997 and 2003, Arlington built, bought, or leased 11 buildings totaling 265,000 sf, using over 6 million kWh/yr
