[EnergyPlus_Support] Tolerance and Unmet Hours



This is a multi-part message in MIME format.
Dear All,

I'm confused about the way energyplus count the unmet cooling/heating
hours. The default tolerance for temperature is set to be 0.2C, and we
increase it to 2C to reduce the unmet hours. I thought the unmet hours
is calculated by using space temperature and setpoint temperature, so
I report the zone mean air temperature to represent the space
temperature and pot it with unmet hours.The cooling setpoint is 25
during occupied, and 35 during unoccupied.2C tolerance for cooling
should give us the up limited temperature of 27C during occupied time.
