What are ventilation requirements designed to specify?

Ventilation requirements are primarily designed to specify the amount of outdoor ventilation air needed for a building. These requirements ensure that the indoor air quality is maintained at acceptable levels, providing sufficient fresh air to dilute indoor pollutants and manage carbon dioxide levels generated by occupants and activities within the space. Proper ventilation contributes to a healthy indoor environment, which is essential for occupant comfort and productivity.

While factors like temperature and humidity can influence overall indoor air quality, they are not the primary focus of ventilation requirements. Additionally, the type of heating system is more related to thermal comfort and energy efficiency rather than the ventilation standards intended to ensure a safe and breathable atmosphere. Thus, specifying the necessary quantity of outdoor air is the key function of ventilation requirements.
