ASHRAE 90.1-2013 addendum cd adds tables 6.8.1-14 and -15 which include an ISMRE requirement for "electrically operated DX-DOAS units, single package and remote condenser."
ISMRE stands for "Integrated Seasonal Moisture Removal Efficiency" and is measured in pounds of water removed per kWh of electrical energy consumed (lb/kWh).
TRANE has a great article on ISMRE and why it's now included in ASHRAE 90.1.
Currently, I'm working on an energy model with a parametric run for a DOAS unit with an ISMRE that is better than baseline, and an EER that is worse than the baseline.
How can I accurately model this improvement in ISMRE, and the resulting reduction in energy usage for the DOAS units?
Googling "eQuest ISMRE" returns only four hits, none of which are relevant.
