Résumé

Thermal environments, indoor air quality, and the ventilation effectiveness of an underfloor air distribution system were measured and evaluated in an actual office building, and compared to an overhead system in the same building with the same floor plan. The main findings were as follows: the horizontal air temperature distribution for the two systems were identical; in both cases, the results suggested that there was probably no discomfort arising from thermal nonuniformity; the underfloor system indicated lower values in both concentration of mass and total number of airborne particles than the overhead system; the ventilation performance of the underfloor system was better than that of the overhead system.
