To calculate Air Changes per Hour (ACH), determine the airflow rate in cubic feet per minute (CFM) using an anemometer or flow meter. Divide the CFM by the volume of the room in cubic feet to obtain the ACH. A higher ACH indicates greater ventilation and better indoor air quality. ACH is crucial for maintaining healthy indoor environments by diluting contaminants, reducing odor, and promoting thermal comfort. Proper ventilation ensures adequate fresh air intake and exhaust of stale air, creating a conducive and energy-efficient indoor space.
Understanding Airflow and Ventilation: The Key to Healthy Indoor Spaces
Hey there, building enthusiasts! Ever wondered how to gauge the air you breathe inside your cozy abode? It’s all about airflow and ventilation, and we’re here to break it down for you in a way that’s as clear as a summer’s day.
Air Changes per Hour (ACH) Measurement: Calculating the Airflow Rate
Imagine your room as a giant bottle of air. To calculate how often the air is being replaced, we use something called Air Changes per Hour (ACH). It’s like refreshing your bottle of soda—the more ACH, the quicker the old air gets replaced with new, fresh stuff.
To figure out ACH, we take the airflow rate (how much air is moving through your room) and divide it by the room volume (the size of your room). It’s a simple math equation:
ACH = Airflow Rate (CFM) / Room Volume (ft³)
Why ACH matters? Because it’s crucial for indoor air quality (IAQ)—the freshness of the air you breathe. High ACH means pollutants like dust, allergens, and unpleasant odors get flushed out faster, keeping your space healthy and comfortable.
So, there you have it! Air Changes per Hour—a simple but powerful tool to understand how your air is flowing. In our next adventure, we’ll explore Ventilation Rate, another key metric for assessing the air quality in your building. Stay tuned, ventilation enthusiasts!

Evaluating Air Quality: The Role of ACH Score
When it comes to measuring indoor air quality (IAQ), the Air Changes per Hour (ACH) score is a crucial parameter. It tells us how many times the air in a room is replaced with fresh air per hour. A higher ACH score indicates a greater exchange of air, which is generally better for IAQ.
But how do we calculate the ACH score? It’s actually quite simple. We need to know the airflow rate, which is the volume of air flowing in and out of the room per unit time. We also need to know the room volume. Once we have these values, we can use the following formula:
ACH = (Airflow Rate / Room Volume) x 60
By multiplying by 60, we convert the units from minutes to hours.
Interpreting ACH Scores and IAQ Factors
So, we’ve calculated the ACH score. What does it tell us?
- Low ACH (below 4): This indicates poor ventilation, which can lead to a buildup of pollutants and allergens, affecting IAQ.
- Moderate ACH (4-8): This range is generally considered acceptable for most indoor spaces.
- High ACH (above 8): While higher ACH scores mean more fresh air, they can also lead to drafts and excessive energy consumption.
It’s important to note that IAQ is influenced by a variety of factors besides ACH, such as the presence of pollutants, allergens, and the efficiency of your HVAC system.
