About the Ventilation Rate Calculator

The Ventilation Rate Calculator is a valuable tool designed to help you estimate the optimal air exchange rate needed to maintain indoor air quality in various spaces. Proper ventilation is crucial for creating a healthy and comfortable environment by ensuring a sufficient supply of fresh outdoor air and reducing the concentration of pollutants indoors.

This calculator takes into account essential factors such as occupancy, room volume, desired air exchange rate, and pollutant sources. By inputting these parameters, you can obtain an estimate of the recommended ventilation rate in cubic feet per minute (CFM), which helps you make informed decisions for a well-ventilated space.

How to Use:

1. Enter the number of people occupying the room.
2. Input the room's volume in cubic feet.
3. Specify the desired air exchange rate (ACH) to meet your ventilation needs.
4. Provide the pollutant sources in CFM per person if applicable.
5. Click the "Calculate" button to obtain the estimated ventilation rate in CFM.

Achieving an appropriate ventilation rate is essential for maintaining a healthy indoor environment, especially in spaces such as homes, offices, classrooms, and commercial establishments. Use this calculator to make informed decisions about ventilation adjustments and create a comfortable and safe indoor space for occupants.
