Americans spend approximately 90% of their time indoors, making it essential to ensure that the air they breathe in various indoor settings is safe. In a recent development, the U.S. Department of Energy’s (DOE) Building America program has highlighted the significance of whole-house ventilation systems in reducing indoor air pollutants, some of which can contribute to cancer risk.

The reports released by the DOE emphasize the importance of proper ventilation systems in lowering concentrations of harmful substances. According to the DOE, inadequate ventilation can lead to the inhalation of airborne pollutants that can have detrimental effects on health, such as radon, a radioactive gas that can increase the risk of lung diseases, including cancer.

Furthermore, everyday activities like cooking can also impact indoor air quality by releasing particles that could harm the lungs. The studies conducted through the Building America program focused on homes constructed between 2013 and 2020, assessing indoor air quality and the impact of ventilation systems in different climates.

The research revealed that many individuals lack the knowledge to operate their ventilation systems effectively, with a significant number of systems not being correctly labeled. However, when these systems were used correctly, the levels of pollutants, including radon, were significantly reduced.

As a result of these findings, the studies recommend the installation of whole-house ventilation systems in all new homes, stressing the importance of proper installation, verification of functionality, and continuous or intermittent operation to maintain desired ventilation rates. Additionally, the Lawrence Berkeley National Laboratory has been actively working on enhancing kitchen exhaust systems to further improve indoor air quality.

In line with efforts to enhance indoor air quality, the DOE has various programs underway, including the Efficient and Healthy Schools program and the Zero Energy Ready Home program. These initiatives aim to promote energy efficiency and indoor air quality in schools and new homes, respectively.

For individuals seeking more information on improving ventilation in both new and existing structures, the Building America Solution Center provides valuable resources and guidance on enhancing indoor air quality.
