1. Resource Efficiency
Utilizing materials that meet the following criteria can accomplish Resource Efficiency

• Recycled Content
  Products with identifiable recycled content, including postindustrial content with a preference for post consumer content.
  
  
• Natural, plentiful or renewable
  Materials harvested from sustainably managed sources and preferably have an independent certification (e.g., certified wood) and are certified by an independent third party.
  
  
• Resource efficient manufacturing process
  Products manufactured with resource-efficient processes including reducing energy consumption, minimizing waste (recycled, recyclable and or source reduced product packaging), and reducing greenhouse gases.
  
  
• Locally available
  Building materials, components, and systems found locally or regionally saving energy and resources in transportation to the project site.
  
  
• Salvaged, refurbished, or remanufactured
  Includes saving a material from disposal and renovating, repairing, restoring, or generally improving the appearance, performance, quality, functionality, or value of a product.
  
  
• Reusable or recyclable
  Select materials that can be easily dismantled and reused or recycled at the end of their useful life.
  
  
• Recycled or recyclable product packaging
  Products that are enclosed in recycled content or recyclable packaging.
  
  
• Durable
  Materials that are long lasting or are comparable to conventional products with long life expectancies.

2. Indoor Air Quality (IAQ)
Indoor Air Quality (IAQ) is enhanced by utilizing materials that meet the following criteria:

• Low or non-toxic
  Materials that emit few or no carcinogens, reproductive toxicants, or irritants as demonstrated by the manufacturer through appropriate testing.
  
  
• Minimal chemical emissions
  Products that have minimal emissions of Volatile Organic Compounds (VOCs).  Products that also maximize resource and energy efficiency while reducing chemical emissions.
  
  
• Low-VOC assembly
  Materials installed with minimal VOC-producing compounds, or no-VOC mechanical attachment methods and minimal hazards.
  
  
• Moisture resistant
  Products and systems that resist moisture or inhibit the growth of biological contaminants in buildings. 
  
  
• Healthfully maintained
  Materials, components, and systems that require only simple, non-toxic, or low-VOC methods of cleaning.
  
  
• Systems or equipment
  Products that promote healthy IAQ by identifying indoor air pollutants or enhancing the air quality.

3. Energy Efficiency
Utilizing materials and systems that meet the following criteria can maximize Energy Efficiency:

• Materials, components, and systems that help reduce energy consumption in buildings and facilities

4. Water Conservation
Water Conservation can be obtained by utilizing materials and systems that meet the following criteria:

• Products and systems that help reduce water consumption in buildings and conserve water in landscaped areas.

5. Affordability
Affordability can be considered when building product life-cycle costs are comparable to conventional materials or as a whole, are within a project-defined percentage of the overall budget.
