What describes balanced ventilation?

Balanced ventilation is characterized by the use of an equal amount of incoming fresh air and outgoing stale air, thereby creating a neutral effect on indoor air pressure. By employing one fan to bring in fresh air from the outside and another fan to exhaust stale air from the inside, balanced ventilation systems effectively manage indoor air quality without creating significant pressure differences that could lead to issues such as drafts or mold growth.

This approach is essential in maintaining a healthy indoor environment, as it ensures proper air exchange, dilutes indoor pollutants, and helps to control humidity levels. The design is centered around the principle of equilibrium, making it an effective strategy for enhancing air quality while minimizing energy loss.

Other options present different ventilation strategies that do not focus on maintaining balance between incoming and outgoing air, which is the key characteristic of balanced ventilation.
