Performances on Indoor Air Quality and Energy Consumption in the Working Spaces using Under-floor Air Distribution (UFAD) System.

Arthur Rosenfeld cited a study showing that the huge link between IAQ and productivity in anoffice building and the serious initiative to improve indoor air quality will have a tremendous return. This study attempts to analyze the working spaces with different variances. The chamber measurements in the laboratory constructed in Shu-Te University will be taken, and the numerical simulation using CFD techniques will also be applied. The results from both should be compared. The different inlet layout of HVAC system, especially the UFAD system, and the boundary conditions will be discussed. The magnitude of PMV-PPD values and temperature profiles will be obtained by BK 1221 Thermal-comfort data-logger and 12-channels thermal-couples data-logger respectively. The k-e turbulence model of RANS was adopted to in all cases of numerical simulations. It is aimed to analyze the details on the energy consumption of VAC equipments and thermal properties under the hot-and-humid subtropical climate, included the summertime and wintertime.
