Table 6.17 shows recommended operative temperatures and maximum mean air velocities for different types of spaces. The table is based on ISO EN 7730 and CR 17.52.
Table 6.18 shows the effect of adding or removing garments on the preferred operative temperature. By individual adaption of clothing it is possible to compensate for individual differences in preferred temperature or for differences in activity level. The table is based on ISO EN 7730 and ISO EN 9920,
