 It has to be noted, that there are some unlogical assumptions and errors in the original set of equations. In the ENVI-met implementation, these errors have been corrected. As a consequence, PET values calculated by ENVI-met may differ from values calculated by other programs, but we see no sense in copying wrong code or unlogical assumptions. Fundamental changes from the original are marked in the description.  It has to be noted, that there are some unlogical assumptions and errors in the original set of equations.

   * For the indoor setting, the turbulent exchange coefficients for heat and vapour are calculated using the indoor air velocity instead of keeping them at the outdoor value   * For the indoor setting, the turbulent exchange coefficients for heat and vapour are calculated using the indoor air velocity instead of keeping them at the outdoor value
-  * The sweat rate and the amount of sweat on the skin is reseted when calculating the indoor environment+  * The sweat rate and the amount of sweat on the skin is set to zero when starting calculating the indoor environment
