Humidity and Buildings. Technical Paper No. 188.

Modified and controlled relative humidity in buildings for certain occupancies is discussed. New criteria are used in determining the needs, desirability and problems associated with humidities in a building. Severe winter climate requires that special attention be given to the problems associated with increased indoor humidities during cold weather. Building enclosures should be designed to avoid accelerated degradation and increased maintenance due to the humidities contained in the building. (TC)
