IAQ is a hot topic today in school environments. Many schools rely on dehumidification units to facilitate proper IAQ and comply with ASHRAE standards. Parkhill Junior High in Dallas, TX, was no exception. Officials were fielding complaints from the approximately 650 students and faculty members about the "musty smell" and high humidity in the 40 classrooms. There was also the problem of uneven climate control throughout the single-story, 111,000-sq-ft building.
"We were getting a lot of complaints about air quality in the school," says Scott Porter, Richardson Independent School District (RISD) hvac maintenance manager. "We were not meeting ASHRAE standards. Some classrooms were freezing cold and others were hot and humid. There were a lot of problems."
