So at the risk of being shown to be wholly ignorant, can anyone point me towards any design documentation regarding radiant heating capacity and how to meet heating loads calculated using "air system" methods? ASHRAE guidance, perhaps?

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.
