[EnergyPlus_Support] Can Radiant system save energy?



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? I could understand the heating energy 
increases because we have more envelope loss. But why then the cooling 
energy decrease? This looks like a little inconsistant to me.
