16
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.

Energy – Considerations
Some Potential Issues Some Recommended Controls
Type and size Determine demand & resource availability
Environmental exposures Confirm established track record within anticipated environment
Proposed location of installation Possible need for structural analysis; safe access for service/maintenance
System certification & vendor track record
Product/system certifications, as well as vendor experience/past work
Physical & health hazards Implement safety and industrial hygiene controls (maintenance)
Warranty – life cycle considerations Product disposed of at end of life
23
Green Materials/Products – Benefits (Wants)
• Low toxicity• Minimal emissions• Low-VOC assembly• Recycled content• Recyclable-reusable• Improved indoor air quality (IAQ)• Sustainable - Renewable• Durable• Healthfully maintained
24
Green Materials/Products - Examples
• Fungi based insulation• Structurally insulated panels (SIP)• Hemp trim boards/insulation• Recycled concrete floors• Petroleum-based vs. Natural Fiber (e.g., wool) carpet.• Cork/bamboo

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 commissionedFull 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
