High humidity in a home can not only be extremely uncomfortable, it can contribute to allergies and respiratory diseases and even foster the growth of dust mites, molds and bugs. To gain a clearer understanding of where high levels of indoor humidity occur, as well as the contributing factors, the U.S. Department of Housing and Urban Development (HUD) funded Steven Winter Associates, Inc. (SWA) to collect a full year of interior humidity and temperature data from 60 homes within three different regions of the United States: the warm, humid Southeast, the cold Northeast and the Pacific Northwest.
The study was aimed at aiding efforts already underway by the ASHRAE Standard Committee 160P and others to develop moisture modeling tools and related technical standards. SWA researchers used Onset® HOBO® U12 Data Loggers to record temperature and humidity levels around-the clock and then used HOBOware® Pro software to convert the data to time-stamped graphs for analysis.
