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.
