Indoor Air Quality (IAQ)
The average American spends over 90% of their time indoors, so creating a healthy and comfortable indoor environment is an important issue for any resident, especially those who are sensitive to poor air quality. Children, seniors, and individuals with respiratory problems and compromised immune systems may suffer more from indoor air quality problems. EarthCraft Builders can improve the health of a home by installing materials with fewer pollutants, flushing any pollutants out through proper ventilation, and controlling moisture to eliminate mold growth. The Indoor Air Quality section consists of items that aim to reduce the presence of pollutants and contaminant in the air inside a home. Reducing or eliminating the presence of manmade pollutants such as volatile organic compounds or natural occurring carcinogens such as radon leads to a healthier environment for occupants.
- IAQ1: Provide whole building and local exhaust ventilation based on ASHRAE 62.2-2016 Ventilation and Acceptable Indoor Air Quality in Residential Buildings:
- IAQ2: : Carbon monoxide detector (one per sleeping area, hard wired with battery back-up
- IAQ3: No unvented combustion appliances, fireplaces or space heaters within or adjacent to the living space. Separate atmospherically vented and/or fan assisted vented appliances from conditioned space.
- IAQ4: If installed, fireplace has ducted outdoor air supply with damper
- IAQ5: If in EPA Radon Zone 1, install a passive radon/soil gas vent system to exterior and label it clearly
- IAQ6: Low- or no-formaldehyde content for finishes
- IAQ7: Low- or no-VOC content paints, stains, or sealants
