Calculation of the insulation requirement in cold environments
In the international standard (ISO 11079) a method is described for calculation of the clothing insulation requirements for given climate conditions. The required insulation value (or index IREQ) is expressed in clo units or in m2°C/W (1 clo=0.155 m2°C/W).
The link above is a version that ISO 11079 refers to. Here is a link to alternative version: IREQ.
Calculation of the Wind Chill Temperature
Also described in ISO 11079 is a new method for calculation of the combined cooling effect of wind and temperature - the Wind Chill Temperature. It is similar to the old Wind Chill Index.
Calculation of the PMV and PPD indices
ISO 7730 describes a method for evaluation of moderate thermal environments and conditions for thermal comfort. The PMV index indicate the thermal sensation vote of people exposed to the actual conditions. PPD gives the percentage of the exposed people that would feel dissatisfied with the conditions.
Calculate PMV and PPD
Calculation of the PHS heat strain index
ISO 7933 describes a method for evaluation of hot environments and the associated physiological strain. The program calculates the time for body core temperature and body water deficit to reach critical levels.

To run separate PHS simulations: http://www.eat.lth.se/fileadmin/eat/Termisk_miljoe/PHS/PHS.html
The same as above but as a separate file that fits for download locally on a computer in order to be run without internet connection: http://www.eat.lth.se/fileadmin/eat/Termisk_miljoe/PHS/PHS_sa.html
Allows to run several PHS simulations. It is possible to change parameters between the timesteps in each simulation. It allows to check the sensitivity in the results by making changes in indata: http://www.eat.lth.se/fileadmin/eat/Termisk_miljoe/PHS/PHS_agenda.html
This sub-section is for looking at variations in the results of PHS simulations when in-parameters are varied around the fixed ones: http://www.eat.lth.se/fileadmin/eat/Termisk_miljoe/PHS/PHS_explorer.html
