tools/process for modeling roof deck surface temperature

Hi Chris,  We have used Honeybee to approximate outdoor surface temperatures. It may not be as accurate as what you are looking for, but it is a starting point. We have started with this basecode from Hydra, you can then add additional EP Material properties, and add a panel to read the surface temperatures or a "Color Surfaces By EP result" component.

Not sure what is the end goal.  We use Radtherm for surface temperature, emissivity, CFD to do UTCI for comfort outdoor etc.  

Hi all, Adding onto this thread because I have a similar question... We are interested in pursuing the WELL Credit T09.1 - "Manage outdoor heat" Part 2 - Temperature Modeling. Does anyone have experience pursuing this? It is asking for modeling thermal perception using things such as Physiologically Equivalent Temperature (PET) or Universal Thermal Climate Index (UTCI). We started to make our own grasshopper tool to visual thermal comfort around our building, but it is mostly looking at air temperature and not including things like humidity and wind. Does anyone have a tool or method they use to calculate this?   This is the language for reference: For pedestrian pathways and building entrances, parking spaces, and plazas, seating areas and other outdoor areas of congregation, project provides the following:

1. Highest expected measure of thermal perception for each month (e.g., highest Physiologically Equivalent Temperature, highest Universal Thermal Climate Index).
2. If the highest measure of thermal perception is associated with “moderate” (or more severe) heat stress, a list of countermeasures within at least two of the following categories and the expected reduction in heat stress that they provide:
   1. Landscaping and greenery.
   2. Manufactured shading systems (e.g., canopies).
   3. Reflectance of manufactured surfaces (e.g., sidewalks, rooftops).
   4. Water features (e.g., ponds, fountains). 

I believe Chris Mackey made a Ladybug tool that uses UTCI.  Check out this video.https://www.youtube.com/watch?v=5nK-rGfPEBk

Thanks Cory. That link was very helpful!
