Full Heat Recovery and low-e ceiling in an Ice Rink

Happy Friday,

I have an energy model of a community center constructed in EQUEST. The
community center has an ice rink incorporated into it which contains a low-e
ceiling as

well as full heat recovery. We were playing around with some combinations of
having a low-e ceiling in our model and as it turns out, there is not much
savings

between having a low-e ceiling and not having one (about $1,000 a year in
savings with the low-e) in our model.

Has anyone else played around with this and noticed it as well? We are
suspecting that you cannot gain much savings through the use of low-e when
full heat

recovery is present. Can anyone confirm this or give any comments?

Thank you,

Hi Justin, The effectiveness of the low-e ceiling depends on the length of your ice-making season (low-e is, of course, more effective in the summer) and on the insulation level in the roof. Adding a low-e ceiling reduces the load on the plant, so you get the same savings regardless of whether there is heat recovery. If you add heat recovery in a building with a low-e ceiling it stretches out the heat recovery payback. Shaun
