All tested (radiant) systems where able to provide
acceptable thermal environment even when (sized)
to 50% of the maximum cooling load.
Cooling load comparison: Air vs. Radiant (TABS)
TABS with nighttime pre-cooling reduced peak cooling load by more than 50% compared to air system in west perimeter zone of an office building
