Which action contributes to improving indoor air quality?

Using low-VOC (volatile organic compounds) finishes and materials significantly contributes to improving indoor air quality. VOCs are chemicals that can easily become vapors or gases and are commonly found in paints, varnishes, and cleaning products. When these materials are used, they can off-gas and lead to poor air quality, causing discomfort or health issues for occupants, such as headaches, respiratory problems, or allergic reactions.

By selecting materials that are low in VOCs, buildings can reduce the concentration of harmful pollutants in the indoor environment. This not only helps in maintaining cleaner air but also supports the well-being and productivity of occupants. This action aligns with sustainability goals, as better indoor air quality contributes to overall health and comfort.

In contrast, reducing the number of windows can limit natural ventilation and decrease the amount of fresh air entering the building, potentially trapping pollutants inside. Increasing building density might lead to overcrowding and higher levels of indoor air contaminants if ventilation is not adequately addressed. Designing without ventilation systems can severely compromise air quality, as proper air exchange is essential to remove pollutants and bring in fresh air. Thus, the choice of using low-VOC finishes and materials stands out as a proactive measure for enhancing indoor air quality.
