The table below indicates sensible and latent (vapor) heat from persons. The values can be used to estimate heat loads that must be handled by air conditioning systems.

Note that the values are based on older ISO and ASHRAE standards. Later ISO and ASHRAE standards should be checked for updated values.

Heat Generated from Human Body

The diagram below is for moderate activity- seated, very light work - computer working person.

Human body heat - metabolism

  • sensible heat = convection and radiation
  • latent heat = evaporation
