What process is used to maintain temperature and supply fresh air in occupied areas?

The process of maintaining temperature and supplying fresh air in occupied areas is known as ventilation. Ventilation is essential for removing stale air, excess humidity, and pollutants, while bringing in fresh air to ensure a healthy indoor environment. It plays a critical role not only in temperature control but also in maintaining air quality, thereby contributing to the comfort and well-being of the occupants.

Ventilation can take many forms, including natural ventilation (which uses windows and vents) and mechanical ventilation (which involves fans and HVAC systems). Proper ventilation helps to regulate indoor temperatures, making spaces comfortable regardless of outdoor climate variations.

While filtration, circulation, and insulation are related concepts in the context of indoor climate control and energy efficiency, they do not directly address the need for fresh air supply. Filtration is primarily concerned with removing particles from the air, circulation involves the movement of air within a space but does not necessarily mean fresh air is being brought in, and insulation relates to preventing heat transfer, thereby contributing to temperature stability but not to air exchange itself.
