[EnergyPlus_Support] Will radiant ceiling use more heating energy?



Hi all,

I use E+ to calculate radiant system compared to traditional VAV system. 
The results showed that radiant system uses more heating energy but less 
cooling and energy. (of course less fan energy and more pump energy). In 
total I could see some energy saving but I would assume this will 
diminish in a heating dominate climate. I wonder what is the energy 
benefits of a radiant system? Is this because we have more envelope loss 
and we heated up some thermal mass in the envelope? Also, what 
percentage of increase do you guys think is reasonable?

Thanks

HJ
