What should be minimized in building air infiltration while still providing necessary fresh air?

The focus of minimizing building air infiltration while ensuring necessary fresh air is primarily on ventilation. Proper ventilation systems need to be designed to provide adequate fresh air to occupants while reducing unwanted air exchange with the outside. This is crucial because excessive air infiltration can lead to higher energy costs due to increased heating and cooling demands.

By managing ventilation effectively, you can supply the optimal amount of fresh air needed for indoor air quality while minimizing the amount of conditioned air that escapes or enters the building through unintended leaks. This balance helps maintain energy efficiency and comfort within the building. Ventilation techniques such as heat recovery ventilators can also aid in achieving this goal, allowing for fresh air intake without losing significant heat or cooling energy.

Heating, cooling, and humidity control are important in maintaining overall comfort and air quality in a building. However, when the specific context is about minimizing air infiltration while still allowing for necessary fresh air, ventilation is key to managing that balance effectively.
