抄録

The actual room air temperature distribution and air-movement have been researched in four office spaces together with an investigation of the views of the occupants with regard to this aspect of comfort. The results show that (1) To restrict complaints about the thermal environment to less than 20 %, room air temperature should be kept below 26℃ when cooling. (2) Vertical gradient of room air temperature increases during heating. To restrict complaints to less than 20 %, a consideration in room environmental design is to maintain the air temperature at floor level (0.1 m above the floor) higher than 21℃ and at head level (1.1 m above the floor) lower than 25℃. (3) To control the vertical gradient of room air temperature, it is important to avoid the excessive declease of floor surface temperature when heating is stopped. (4) Information has been given on the relationships between sensation of air-movement and discomfort, and between room air temperature and desirable air-movement.
