[EnergyPlus_Support] Re: Football Stadium Modeling

["hisham.rashrash" <hisham.rashrash@xxxxxxxxx>]

Many thanks for your help, but please, can you make the EMS input a little more clearer, I haven't used EMS before. This would be very kind of you.
Thank you very much.

Best regards,
Hisham

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 that resembles the roof.
