  In addition to Mario's comment, you might also look at your 
assumptions for the amount of infiltration in your greenhouse and the 
ground temperature underneath your greenhouse. Depending on how you 
created the Studio project (either using the import wizard or manually) 
you may not be accounting for any infiltration. Greenhouses typically 
have fairly high infiltration rates.

kind regards,
