We just started to make greenhouse models using TRNSYS17. Probably we will select Type 56 building and have two zones, one for upper air space and the other zone with plant canopy. Combination with CONTAM would be the next step. Any suggestions and comments which can be given by forerunners would be very much appreciated.
