`calcdTNZ`

calculates the distance from the thermoneutral zone, either skin temperature or room air related.

`ht` |
a numeric value presenting body height in [cm] |

`wt` |
a numeric value presenting body weight in [kg] |

`age` |
a numeric value presenting the age in [years] |

`gender` |
a numeric value presenting sex (female = 1, male = 2) |

`clo` |
a numeric value presenting clothing insulation level in [clo] |

`vel` |
a numeric value presenting air velocity in [m/s] |

`tskObs` |
a numeric value presenting actual mean skin temperature in [degree C] |

`taObs` |
a numeric value presenting air temperaturein [degree C] |

`met` |
a numeric value presenting metabolic rate (activity related) in [met] |

`rh` |
a numeric value presenting realtive humidity in [ |

`deltaT` |
a numeric value presenting the resolution of the matrix to be used |

`fBasMet` |
a string presenting the method of calculating basal metbolic rate. Needs to be one of "rosa", "harris", "miflin", or "fixed". Fixed will result in the value of 58.2 W/m2. |

`fSA` |
a string presenting the method of calculating the surface area. Needs to be one of "duBois" or "mosteller". |

`percCov` |
a numeric value between 0 and 1 presenting the percentage of the body covered by clothes in [ |

`TcMin` |
a numeric value presenting the minimum allowed core temperature in [degree C]. |

`TcMax` |
a numeric value presenting the maximum allowed core temperature in [degree C]. |

`plotZone` |
a boolean variable TRUE or FALSE stating, wether TNZ should be plotted or not. |

The percentage of the body covered by clothes can be estimated e.g. based on ISO 9920 Appendix H (Figure H.1). A typical winter case leads to a value of around .86, in the summer case this goes down to values around .68.

`calcdTNZ`

returns a dataframe with the columns dTNZ, dTNZTs, dTNZTa. Thereby

`dTNZ ` |
The absolute distance to the centroid of the thermoneutral zone |

`dTNZTs ` |
Relative value of distance assuming skin temperature to be dominant for sensation |

`dTNZTa ` |
Relative value of distance assuming ambient temperature to be dominant for sensation |

This function was used in earlier versions of TNZ calculation (see references above). The newest version is `calcTNZPDF`

.
In case one of the variables is not given, a standard value will be taken from a list (see `createCond`

for details.
