the lack of good quality of indoor air may adversely impact these children - and the adults who teach them. "we know that fresh air, proper circulation and managing humidity are important in our homes," said dr. mary lasley, pediatric allergist. "Why shouldn't this be true in a school?"
part of the air quality problem can be traced to energy conservation. Since the energy crisis in the 1970s, buildings have been tightened up to conserve energy, leading to fresh air circulation problems. And school systems tend to close down heat and air systems at night to further conserve energy. This can easily expand problems of poor air circulation and create excess relative humidity in the school, contributing to mold and dust mite growth.
