Abstract

In a Lawrence Berkeley National Laboratory (LBNL) study, researchers compared the operating profiles of two mechanical ventilation (HVAC) systems alternated over nine weeks during Fall 2001. This was done using pairs of classrooms sited adjacent to one another and equipped with either standard or low emission interior finish materials. In the present study, statistical analysis indicated school-classroom B-A containing carpet (with polypropylene/polyolefin backing) and teaching materials (with bare surfaces) had higher fine particle number count (PNC; PM0.3-0.5/PM0.5-0.7) than its counterpart. Also, elevated humidity coupled with elevated inferred ozone at school-classroom A-B yielded comparatively elevated PNC.
