What is the formula to calculate ventilation based on volume?

The formula for calculating ventilation based on volume is derived to ensure adequate indoor air quality and to meet the necessary standards for ventilation in building design. In the context of the choices provided, the correct calculation involves considering the volume of the space and a specific factor that aids in converting this volume into an appropriate airflow rate.

To elaborate, the formula indicating ventilation as 0.35 times the volume, divided by 60, accounts for the need to convert cubic feet per minute (CFM) when assessing the amount of fresh air needed in a space over an hour. This factor is typically used to establish the air exchange rate, which is essential for maintaining air quality in buildings, especially in residential settings.

Given that ventilation is fundamentally tied to ensuring sufficient airflow regardless of the physical dimensions of the space, it is critical to have a consistent method of calculation that accurately reflects real-world conditions. Thus, using the factor of 0.35 in the established formula provides a meaningful approach to quantifying air requirements based on volume.

In analyzing the other choices, it is evident that they either do not take into consideration the proper factor for ventilation or focus on different aspects, such as square footage or total airflow calculations, which do not align with the standard method for calculating ventilation
