What is typically used to achieve high indoor air quality in a construction project?

Using low-VOC materials is a proven method to enhance indoor air quality in construction projects. VOCs, or volatile organic compounds, are chemicals that can be released into the air from various building materials and can contribute to poor air quality and health problems for occupants. By selecting materials that emit little to no VOCs, such as certain paints, adhesives, flooring, and finishes, the overall indoor air quality is significantly improved.

In contrast, high-density insulation, while important for thermal performance and energy efficiency, does not directly impact indoor air quality in the way that low-VOC materials do. Similarly, metal roofing and concrete foundations are structural elements primarily concerned with durability and weather resistance, rather than the air quality of indoor environments. Therefore, while all options are relevant to construction, only low-VOC materials specifically target the improvement of indoor air quality.
