thermofeel 2.0.0

A library to calculate human thermal comfort indexes

thermofeel (pronounced thermo-feel)

A library to calculate human thermal comfort indexes.

Currently calculates the thermal indexes:

• Universal Thermal Climate Index

• Apparent Temperature

• Heat Index Adjusted

• Heat Index Simplified

• Humidex

• Normal Effective Temperature

• Wet Bulb Globe Temperature

• Wet Bulb Globe Temperature Simple

• Wind Chill

In support of the above indexes, it also calculates:

• Globe Temperature

• Mean Radiant Temperature

• Mean Radiant Temperature from Globe Temperature

• Relative Humidity Percentage

• Saturation vapour pressure

• Wet Bulb Temperature

PyPi

Install with:

$ pip install thermofeel

Testing

System dependencies

thermofeel core functions depend on:

• numpy

• earthkit-meteo > 0.0.1 - for solar zenith angle calculation

Optionally, thermofeel depends on:

• pytest - for unit testing

Release notes

Thermofeel 2.0 brings a number of changes to the underlying code but most importantly to the API.

Consequently, downstream packages using thermofeel 1.* will require code changes to migrate to version 2.0 and beyond.

The main changes are:

• standardisation of input and output variables

• standardisation of variable names

• removal of dependency on numba for code acceleration

• removal of solar zenith angle calculation (now provided by earthkit-meteo)

• several bug fixes and improvements

Please consult ChangeLog for more details.
