How does LEED address indoor air quality through material use?

LEED addresses indoor air quality primarily by incentivizing the use of low volatile organic compound (VOC) materials. VOCs are organic chemicals that can evaporate into the air and contribute to indoor air pollution, leading to health issues and discomfort for building occupants. By encouraging the selection of materials that emit fewer VOCs, LEED helps to create healthier indoor environments. This is vital for enhancing the well-being of occupants and reducing the risk of long-term health effects.

The focus on low-VOC materials aligns with LEED's overarching goal of promoting sustainability while ensuring the safety and comfort of building users. As buildings are often sealed to improve energy efficiency, the quality of the indoor air becomes even more crucial, making the selection of appropriate materials an essential part of a comprehensive indoor air quality strategy.

In contrast, the other choices do not directly contribute to the improvement of indoor air quality in the same way that low-VOC materials do. High-traffic flooring materials, natural lighting, and locally sourced products may have their own benefits, but they do not specifically address air quality concerns related to the materials used in construction and finishes.
