I wrote a short ems to do this for freeze protection trace heating on piping... you can adjust it for pitch heating.

Dear all,

I have a project for a football stadium which has underground heating for the playing pitch area. The stadium is open to the outdoors. The question is: Can such stadium pitch heating be modeled in EnergyPlus? if yes, how? and also how to account for the impact on outdoor environment factors effects (like wind or rain) caused by seating and exterior walls (which are shaped as displaced high columns around seating with open spaces between them), also there is the open structure above
