IAQ vs. IEQ
Too Broad vs. Too Narrow
What is Good IEQ?
- Odor: Just because a building smells bad doesn’t mean it poses a hazard and vice-versa. A building that smells bad may or may not be healthy, but at a minimum it is distracting and uncomfortable. Likewise, an indoor environment that smells too good can be equally distracting.
- Temperature: Employees who are too cold, either locally (hands, nose, feet) or uniformly (core temperature), can suffer productivity and morale losses, plus their insufferable teeth chattering annoys the customers. Overheated employees risk suffering a fate of continuous complaints about discomfort.
- Relative Humidity: Relative humidity is a term R&R readers are likely quite familiar with, since many of you respond to water incursions. As masters of psychrometry, you skillfully convert wet buildings into dry buildings. But, in terms of IEQ comfort, a building that is too humid can be perceived as stuffy. High humidity, or a low dew point, can also be problematic. Keep in mind, condensation can lead to secondary environmental degradation, such as mold and bacterial growth. Conversely, if the relative humidity is too low, indoor air will be perceived as too dry and can result in itchy ashy skin, dry, irritated eyes, nose bleeds, chapped lips and the need to apply voluminous quantities of moisturizers.
