The Importance of Ventilation in Controlling Humidity

Proper ventilation can remove indoor air pollutants, contribute to temperature control, and regulate indoor humidity. Improper ventilation, on the other hand, can sweep in harmful pollutants, increase indoor humidity, and invite in allergens like pollen and dust. But what is ventilation and how does it relate to humidity control?  

The Importance of Proper Ventilation  

If your commercial building is equipped with HVAC, ventilation is likely already a part of your climate control system. However, HVAC is rarely optimized for controlling the humidity or air quality of your specific indoor climate. Before we explore how ventilation affects humidity, what is it and why is it important? 

What is Ventilation?

Ventilation is the introduction of outdoor air into an indoor space to facilitate improved air quality, humidity levels, air pressure, and temperature regulation.  

Effects of Poor Ventilation

Some of the effects of improper ventilation include the following:

  • Higher frequency of airborne infectious diseases. 
  • High levels of CO2.
  • Higher frequency of respiratory problems including asthma and allergy attacks. 
  • Higher prevalence of mold and mildew growth. 
  • Increased levels of indoor air pathogens. 
  • Increased odors, perception of “stale air”.

The Importance of Ventilation for Humidity Control

Proper ventilation plays a significant role in humidity control efforts; in addition to bringing outdoor air into an indoor space, ventilation is also used to move indoor air outside of the building. This process improves indoor air quality and can contribute to lowered humidity levels if done properly.

Here’s how it works:

Based on the moisture generated in a building from its particular use and moisture infiltrating the space from the exterior, experts can determine the humidity load using a formula. In this way, they can determine the necessary rate at which humidity must be removed from the indoor climate to maintain a steady humidity level.

The optimal indoor relative humidity is between 40 and 60 percent.  If we were to bring in outside air without conditioning it first, we could increase the humidity load depending on the geographic location or time of year so make-up air needs to be conditioned prior to being released into the facility. One option is to use the fresh air intake capability of the Quest Dehumidifiers to ensure the incoming fresh air is dehumidified and filtered prior to entering the space.  Ensuring that each area is ventilated properly will help to regulate the overall humidity levels in your building.

Is your building suffering from the effects of high humidity levels? Mold growth, a mildew odor, damaged books or paper materials, and damaged electronic equipment are all symptoms of a much larger problem. Regulating the humidity levels in your space is the most efficient and effective way to solve these issues.
