Abstract

This was a secondary, retrospective analysis of 2001-02 Lawrence Berkeley National Laboratory (LBNL) nested, crossover-design study data. LBNL evaluated and compared operating profiles of two mechanical ventilation (HVAC) systems alternated over nine weeks using pairs of relocatable classrooms (RCs) sited adjacently and equipped with standard or alternate (lower chemical emissions) interior finish materials. There were two California school districts (SD): SD-A in a coastal, temperate climate and SD-B in warmer Central Valley. Mixed models demonstrated IDEC use (100% outdoor air intake) at SDB-A, yielded significantly greater indoor particle number counts PNC (PM0.3-0.5/PM0.5-0.7) than in other RC. SDA RC Bard use (50% outdoor air intake) yielded comparatively greater PNC than IDEC use.
