| Abstract |
During the last decade, an increasing interest in Underfloor Air-Conditioning(UFAC) systems has emerged. The purpose of this paper is to evaluate comprehensively the indoor environmental performance of office buildings with UFAC system in order to develope the design prototype of this system. In this paper, the physical measurements and the interviewing survey of occupant's sensation responses to the environment were carried out. Measurements and survey were made of the thermal environmental factors such as air temperature, relative humidity, air velocity, globe temperature, and the other several environmental factors such as the sound level and the illuminance of working plane, etc. And, the air quality was evaluated by measuring the concentration of suspended particles, carbon monoxide, and carbon dioxide in the room.Furthermore, the paper appraises the various indoor environmental factors of the room by using post-occupancy evaluation(POE) method in office building with UFAC system, and thus, it suggests the basic data for assessing the indoor comfort based on field measurements and survey. |
