Description

This study examined the illuminance, temperature, and humidity in patient rooms facing south and north to elucidate the effect of patient room orientation and open or closed partition curtains on patient room environment. The average levels of illuminance at the window side of patient rooms facing south were 3964 lx at 7:00 a.m., 4304 lx at 11:30 a.m., and 1652 lx at 4:00 p.m., showing that the illuminance in the patient rooms facing south was high in the early morning and became low in the afternoon. Meanwhile, the levels of illuminance in the patient rooms facing north were 1914 lx at 7:00 a.m., 3746 lx at 11:30 a.m., and 4052 lx at 4:00 p.m., indicating that sunlight resulted in high levels of illuminance in the afternoon, making the room environment at night favorable. In addition, the recommended level of illuminance in patient rooms could be achieved more easily by fully opening partition curtains in early morning. There was no significant difference in the mean temperature between the rooms facing north and the rooms facing south. The mean humidity in the patient rooms facing south and north were 48.1±10.4% and 50.7±9.9%, respectively, showing significant difference at p=0.006.
