How can energy-efficient buildings potentially impact indoor air quality?

Energy-efficient buildings are designed to minimize energy consumption, often resulting in airtight structures that can significantly decrease energy loss. This approach can inadvertently result in poor indoor air quality if proper ventilation and indoor air quality management practices are not implemented. When buildings are sealed to improve energy efficiency, the natural exchange of indoor and outdoor air is restricted, which can trap pollutants such as volatile organic compounds (VOCs), particulate matter, and carbon dioxide indoors.

Without effective mechanical ventilation systems to balance energy efficiency with adequate air exchange, occupants may experience elevated levels of indoor contaminants. Therefore, while the intention behind energy efficiency is to create a sustainable environment, it emphasizes the need for careful planning and monitoring of air quality to prevent health-related issues.

Through the correct management of ventilation and regular maintenance, building occupants can enjoy the benefits of energy efficiency alongside a healthy indoor atmosphere. Hence, the statement highlighting the potential for poor air quality if not properly managed accurately reflects the complexities involved with energy-efficient building practices.
