The unmet hours can be seen in the BEPS report: “Hours any zone above the throttling range,” and you can see here that we have over 2,000 unmet heating hours, and 300 unmet cooling hours. The ASHRAE 90.1 rule is that we need to …

Apr 24, 2013 · Standard eQuest throttling range is 4F. Throttling hours are in 5F bands , 65, 75 and 80 being the critical bands for unmet hours. Typical buildings are controlled at 70F for heating and 75 for cooling aligning with the cut-off points …

The unmet load hours isn't crazy significant--around 450 hours--however, the simultaneous heating and cooling is what is bothering me the most. I want to make sure that I'm modeling the building as accurately as possible, as opposed to building it with questionable "workarounds" to get rid of unmet hours. Some background on the model:

eQuest auto-size the heating capacity to meet the load required? I have numerous systems with unmet load hours because of this type of warning and need some advice on how or where to start in my attempt to get rid of these unmet load hours for my EAc1 submittal. Thanks.

Unmet load hours are any hours of operation when conditioned spaces are outside the throttling range for heating or cooling controls. That is, they are the hours in a year that the HVAC system serving a space cannot maintain space setpoint. If unmet load hours for multiple spaces coincide (occur in the same hour), they are

I'm attempting to model a school in eQuest and I'm having some trouble with unmet hours. The building is located in a cold climate (Calgary, Alberta) and I've selected the "Pkgd Var Vol" system type. The problem seems to have something to do with with way that I've set up this system. In ATTN report I'm getting a warning like so: PREHEAT/HEATING-CAPACITY in SYSTEM AHU-1 is …

So, Unmet Load Hours are defined in trace as the hours when the building load is in excess of the design coil capacity by 1% or greater and one or more rooms are 1.5 degrees Fahrenheit beyond the room thermostat setpoint range for that hours, and the coil does not have the capacity to bring it to setpoint.

Check here for unmet load hours, defined as hours when one or more zones are out of the throttling range. The denominator used for this calculation is 8,760 unless the total run hours for the longest-operating air handler is reported (SS-R report). If this value is provided along with the SS-R DOE-2 output for that

Does anyone know if there is a report or means from eQuest 3.65 to generate the EFLH (equivalent full load hours) for each schedule? Colleague of mine believes VisualDOE was able to calculate & report. Hoping eQuest has a comparable tool/report.
