Can radiant system saves energy?

1 post / 0 new

I use E+ to calculate radiant system compared to traditional VAV system. The results showed that radiant system uses more heating energy and 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 for heating?
