    This is the time of the year when cool, damp, and rainy weather causes mold growth in schools without any major water leaks. By monitoring the indoor relative humidity continuously and taking action when the relative humidity exceeds 60% for 48 hours, mold growth is avoided. The action required is to reduce the relative humidity to <50% for a minimum of 12 hours per day. Reducing the relative humidity requires dehumidification without cooling the space temperature. To control relative humidity, we recommend 100 pints of dehumidification per 3,000 FT^2 of space. Because schools are not occupied through the summer, high humidity goes unnotice until next fall. When class activities begin in fall, odors are noticed, complaints filed, and the investigation commences. Experts are called in, testing begins, and money flows. Most of the time, the cause is not pinpointed or at best a dripping a/c, small water leak is blamed. Phantom humidity strikes again. Its a simple task to monitor relative humidity and less expensive to control the relative humidity than investigate the complaint later.
