PET Body Parameters

PreviousMesh to HatchNextPassive Strategy Parameters

Last updated 2 years ago

-

Create a set of parameters that define the body characteristics for the PET model.

These parameters can be plugged into any of the components that compute PET thermal comfort.

Inputs

  • age

The age of the human subject in years. (Default: 36 years for middle age of the average worldwide life expectancy).

  • sex

A value between 0 and 1 to indicate the sex of the human subject, which influences the computation of basal metabolism. 0 indicates male. 1 indicates female and any number in between denotes a weighted average between the two. (Default: 0.5).

  • height

The height of the human subject in meters. Average male height is around 1.75m while average female height is 1.55m. (Default: 1.65m for a worldwide average between male and female height).

  • body_mass

The body mass of the human subject in kilograms. (Default: 62 kg for the worldwide average adult human body mass).

  • posture

A text string indicating the posture of the body. Letters must be lowercase. Default is "standing". Choose from the following:

* standing

* seated

* crouching
  • humid_acclim

A boolean to note whether the human subject is acclimated to a humid/tropical climate (True) or is acclimated to a temperate climate (False). When True, the categories developed by Lin and Matzarakis (2008) will be used to assess comfort instead of the original categories developed by Matzarakis and Mayer (1996).

Outputs

  • pet_par

A PET comfort parameter object that can be plugged into any of the components that compute PET thermal comfort.
