Recently, OA, TC systems have been applied to intelligent office buildings and an access floor system is needed to manage wires for these systems. The floor-based air-conditioning system was introduced to use access floor and aim to economical motive such as reducing floor to height level. The purpose of this paper is to evaluate comprehensively the indoor environmental performance of office buildings with floor-based air-conditioning system in cooling period. The physical measurements were carried out. Measurements 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 indoor air quality and the illuminance of working plane, etc. The indoor air quality was evaluated by measuring the concentration of suspended particles, carbon monoxide, and carbon dioxide in the room. This paper appraises the various indoor environmental factors of the room in office building with floor-based air-conditioning system, and thus, it suggests the basic data for assessing the indoor comfort based on field measurements.
