Hello group,

I?m unsure how to deal with interstitial spaces between floors (see sketch attached) that are only indirectly heated and cooled. This is for a LEED project, so I have to document how I account for the energy in eQuest. The spaces are not occupied, and should not count toward building area gross square feet. Simply treating the spaces as unconditioned on one side of a horizontal partition won?t be very accurate.

I have considered modeling the interstitial spaces separately, exporting the hourly loads and temperature profiles, and creating some sort of internal load to represent them ? but that sounds like a long way around to get where I?m going.

Does anyone have a hint for me?

Thanks!
