[EnergyPlus_Support] Re: Trees
Thank you.
This is a great but very complicated concept.
I guess There are too many assumption in here and I realize the I am trying to use a tool that meant to do one thing to do another.
I just need to find a better tool to that job, and maybe after that to play with the weather file back here.
thank you for all the time and explaining

Introduce the outside air in the zone "tree" using infiltrations or ideally by air flow network achieving the connection between the building and tree zone. The exterior heat gains gathered in step 1 are introduced in the space as scheduled internal loads.
