a. Full calculation of mean radiant temperature tr as follows:
- Step 1: Determine long-wave mean radiant temperature trlw .
- Step 2: Determine short-wave mean radiant temperature trsw using Normative Appendix C.
- Step 3: Mean radiant temperature tr is equal to trlw +
trsw as determined in Steps 1 and 2. b. Use a mean radiant temperature tr that is 2.8°C (5°F) higher than average air temperature ta if all of the following conditions are met:
tr
trlw
trsw
tr is equal to trlw + t rsw
