Leen,
Thanks for this tips, your PhD is helpful.
But now I would like what is TRNSYS code – which way does TRNSYS calculate operative temperature?
Does program take into account also heat gain in the zone or only surfaces and air temperature?

Karol,
that depends on the viewfactors. the operative temperature sensed by a person depends on his/her location in a room.
If you check the book of Ole Fanger, you will be able to find that explanation. A part of it, specifically applied to a radiator case is also in my PhD.
If the 'radiating object' is close to a person and the location of the person in the zone is thus clearly defined, his/her actual thermal sensation will be influenced by the radiating object in case it is large enough or the temperature is high enough.
However, the added value of a detailed calculation is limited in case the real life scenario would be one where furniture is blocking the viewfactors between radiating object and person.

Dear All,
Do you know which objects are taken into account in operative temperature calculation?
Air, walls, floor, ceiling for sure, but for example radiative heat gain that is modeled in zone?
I will be grateful for any comments!
Regards,
Karol
