All,

I am getting unusually high heating energy savings, ~50%, when I apply chilled beams (induction units) to patient rooms in a hospital.

I just stumbled across another energy report written by another firm for a laboratory project of ours that shows the same results, ~50% heating energy savings when applying chilled beams.

The cooling and electricity savings are in line with what would be considered reasonable and I realize there should be some heating savings due to a reduced reheat load, but 50% seems excessive.

Both buildings have approximately 40% of the floor area using chilled beams.

The lab is in a cold climate, the hospital is in a more temperate climate.

Has anyone else come across this issue?

Thanks,
