Value
- Humidification at a building is important to maintain occupant comfort
- When the relative humidity at a building is too low, occupants will become uncomfortable This is often the case in cold climates during winter months when the air becomes dry
- If a building is located in a climate that experiences cold, dry winters, install humidification systems to maintain a comfortable RH level at their building
- Properly maintain humidification systems to ensure optimal indoor conditions are maintained
RELATED Question:
Description
Low indoor relative humidity is a common problem in cold climate buildings during winter months and a common source of indoor air quality complaints. The addition of a carefully maintained whole-building humidification system, that is focused on human comfort, can help maintain a more comfortable work environment.
Humidification systems should be cleaned and inspected annually. ASHRAE 180-2018 recommends annual inspection and cleaning of strainers, drain pans, distributors and semi-annual cleaning of steam traps, pumps and controls
