Author(s) : SHINADA Y., KIMURA K. I., KATSURAGI H., et al.

Summary

The specific features of natural ventilation system combined with solar chimney and underground pit installed in a new school building and the measured results for four years are described. In summer and intermediate seasons, outside air is introduced into the building of four stories through underground pit from the intake provided in the north end, brought into the different occupied rooms from which the room air is discharged to outside through the solar chimneys of 8 meters high above the roof by chimney action or pulling out action by wind. The measured results for four years after opening the school showed that the energy performance has improved year after year owing to the natural ventilation system. Some consideration on the improvements in the system performance is given for future design of natural ventilation with solar chimney.
