Clothing Surface Temperature #23

Closed nllong closed 4 years ago

It appears that the initial value for the clothing surface temperature may be incorrect. Since this iterates, then I'm not sure it matters. It would be nice to have it be the same as ASHRAE Std 55 2017 Normative Appendix B (screenshot below).

thank you very much for picking up this, however, the equation was later changed in the ASHRAE 55 2017 addendum B and now reads: tcla = taa + (35.5 - ta) / (3.5 * icl + 0.1)

Thanks for clarifying! Closing.
