PET (physiological equivalent temperature or heat stress) result type overlay (Wageningen)

The physiological equivalent temperature is a value which expresses the effective outdoor temperature of a (complex) outdoor situation as an equivalent (simple) indoor situation. The equivalence is determined as the point where the heat balance of the human body is balanced with the surrounding environment.[1] In other words, the PET of any given situation outdoors is equal to the temperature indoors at which the human body would gain or lose the same amount of heat.
