Thread-topic: MRT under solar radiation

Hello,

I want to assess the thermal comfort under solar radiation in a building. The ASHRAE-55 standards proposes a method to calculate the Mean Radiant Temperature including the solar radiation.

I haven’t seen so far an add-on or a Type that performs this calculation. Given that all the information required (view factor, radiation heat flux, surface temperatures) are available in the building type, it should be easier to calculate it within the simulation instead of exporting all the data for a post-treatment.

Is it in mind to develop such an add-on or if no, could it be if the need is growing ?

Best regards
