What is the main advantage of balanced ventilation systems?

Balanced ventilation systems are designed to supply and exhaust equal amounts of air, which is the key reason why they maintain equal air pressure indoors and outdoors. This balance is crucial for improving indoor air quality and comfort. When a ventilation system supplies as much air as it exhausts, it helps to prevent issues such as pressure differentials that can lead to drafts, backdrafting of combustion appliances, or ingress of unconditioned air.

Additionally, maintaining this balance contributes to temperature stability within the building, enhancing overall occupant comfort. The controlled exchange of air allows for the removal of stale air and the introduction of fresh outdoor air without compromising the internal environment.

While other options touch upon characteristics of ventilation systems, they do not directly address the primary benefit of balanced ventilation and the comprehensive comfort and efficiency it offers to building occupants.
