Going Green – Governments are On-Board• As of August 1, 2008: LEED Initiatives (Legislation, Exec Orders,

Resolutions, Ordinances, Policies & Incentives) can be found in:

98 Cities, 29 counties, 25 towns, 31 states, 12 fed agencies or depts., 15 public school jurisdictions & 38 institutions of high education.

Most recent Examples (U.S. GBC LEED Initiatives in Govt. & Schools):

• June 28, 2008: State of Indiana: Executive Order 08-14; requires all new state buildings to earn LEED Silver certification, EPA’s Energy Star rating, two Globes under GBI (or similar green building rating system). Also impacts renovations of existing state buildings.

• June 25, 2008: State of Florida: HB 7135; requires all new construction and renovation of state buildings to follow LEED or similar guidelines. As of July 1, 2008, requires same from counties, municipalities, school districts, water mgt districts, state universities, community colleges, and Florida state courtS.

26

Considerations For Green Materials/Products

Some Potential Issues Some Recommended Controls

Green does not always = green (“green washing”)

Always evaluate a product’s greenness – avoid being “green washed”

Green does not always = safe Ensure evaluation of traditional product safety concerns and controls

New products & technologies - lack of standards, track record & certification

Confirm established track record and certifications for intended use

Durability & proper installation (construction defect)

Review lab & real-world testing data

Vendor/contractor experience with green products/materials

Contractor w/ track record for specific products of interest

Life cycle considerations Product disposal at end of life

27

Site Sustainability

• Site selection – mindful of location to be developed (environmentally sensitive; pre-existing infrastructure).

• Erosion control/management – quantity & quality (construction and non-construction)

• Brown field redevelopment – rehabilitating damaged sites

• Greenfield sites – habitat protection or restoration

• Proximity to mass transit – assists in reducing pollution

• Heat island effects – roof & non-roof design features

• Bicycle racks/changing rooms – low or no-emission transit

Leaving no footprint, or improving the footprints left by others, for future generations.

28

Considerations For Site Sustainability

Some Potential Issues Some Recommended Controls

Higher costs if not considered early in project

Pre-planning discussions and detailed design reviews

Brownfield redevelopment – lack of scope for remediation

Independent site assessment and detailed remediation plans

Erosion control mgt. – Failure to meet requirements

Master plan should consider both quantity and quality – approvals

Habitat restoration Ensure site survey and inclusion in master plan for building

Heat island effects Site survey plans for shade, vegetated roof and/or high reflectance covering, paving materials

29

Conservation – Focus On Water

• Low flush toilets/waterless urinals/occupant sensors

• Low or no irrigation landscaping

• Point of use hot water heating systems

• Hot water recirculation systems

• State of the art irrigation methods

• Rain water capture and re-use

• Greywater recovery/re-use systems

30

Considerations For Conservation – Focus On Water

Some Potential Issues Some Recommended Controls

Lack of routine inspection and maintenance

Establish both routine and PM inspection/maintenance for water efficiency systems

Plant species can affect indoor air quality

Proper planning and consultation for drought-resistant plants

Failure to properly treat greywater, or using greywater in non-approved applications

Ensure greywater system controls are established, and systems are routinely inspected/maintained

31

Indoor Environmental Quality

• Green air is clean air (or should be):

Operable windows

CO2 monitors

Moisture control techniques (minimizing mold growth)

Advanced air filtration systems (pleated, electrostatic, HEPA)

Reduction of “off-gassing” via low or little emission adhesives, paints, stains, or products

High insulation factors (tight building)

32

Considerations For Improved IndoorEnvironmental Quality (IAQ)

Some Potential Issues Some Recommended Controls

Lack of HVAC commissioning and calibration

Verify HVAC systems are installed, calibrated and commissioned

Full building air flush

Operable windows Appropriate rules concerning use, and follow-up with occupants

New “low or little off-gassing” (low VOC) products/materials

Evaluate new materials for potential issues prior to selection & installation
