Arlington County Government

MWCOG Energy & Air Quality Conference, April 5, 2004

opportunities in three areas

Opportunities in three areas

Green buildings for County gov’t

Green building incentives for private developers

Energy-efficiency improvements in existing buildings

slide3

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

leed defines green 1

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

leed defines green 2

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

leed defines green 3 energy atmosphere credits are prominent

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

leadership in energy and environmental design leed

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.

langston brown school community center

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

green building programs for private development
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

leed scorecard for development projects
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

leed scorecard for development projects11
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

green building incentive program
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

green building incentive program13
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

  • 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

energy efficiency improvements to existing buildings 1

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%

energy efficiency improvements to existing buildings 4

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

importance of paying attention to both new construction and existing stock

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
