Relative Humidity Comfort

Humidity is a factor in thermal comfort.

Relative humidity comfort. The influence of relative humidity on thermal comfort was studied in an environment chamber. According to the environmental protection agency indoor relative humidity should be kept below 60. Ideally between 30 and 50.

Warmer air can hold more moisture. Relative humidity has a small effect on thermal comfort outdoors when air temperatures are low a slightly more pronounced effect at moderate air temperatures and a much stronger influence at higher air temperatures. Typically with higher winds and relative humidity lower than 25 percent you are nearing critical fire danger.

Radiant heat hot surfaces or radiant heat loss cold surfaces are also important factors for thermal comfort. Below 30 can result in unpleasantly dry conditions leading to skin and eye irritation. High relative humidity reduces people s ability.

Given that air at low relative humidity has a much better capacity to absorb water vapour it makes sense a person exposed to 35 degree celsius temperatures and 25 per cent relative humidity as in a melbourne summer will feel more comfortable than someone exposed to 35 degree temperatures and 60 per cent relative humidity a darwin summer. What s the ideal relative humidity level for comfort. Relative humidity rh is a measure of the moisture in the air compared to the potential saturation level.

Although relative humidity is an important factor for thermal comfort humans are more sensitive to variations in temperature than they are to changes in relative humidity. Above 60 and the air will start to turn swampy. What happens if humidity levels are high.

Relative humidity is an important environmental factor that could affect thermal comfort in a building. This is an easy data point to access for forecasting fire danger regardless of the.
