Harry Schechter, founder of Temperature@lert (www.temperaturealert.com), says:

Should IT and data center managers be as concerned about humidity as some experts think?

If you’re sticking with the traditional cool temperatures in your datacenter, it’s not much of a worry any more. However, if you decide to outfit your staff with Bermuda shorts, it’s time to start watching humidity.

Humidity can also change dramatically if you have a large increase in the number of people in a smaller room. In addition to generating heat, a person expels moisture with each breath – think back to sitting in a parked car in high school. j/k. If you’re experiencing a particularly large number of staff members working in a smaller sized datacenter, this could affect the humidity level. Of course, a properly designed large scale center probably won’t need to ever worry about this.
