When the HVAC System Minimum Timestep was set to the most detailed setting (1 minute), the change in unmet hours for this specific scenario was dramatic, with only 36 unmet hours occuring. Using 1 minute is extreme and may not be suitable for your situation. Using 1 minute could adversely impact the performance and calculation time of your model.

Unmet load hours are triggered in TRACE when space conditions are outside of the thermostat setpoints. Unmet hours can occur for a very wide variety of reasons and are restricted to hours when the excess load on a coil is at least 1% greater than the design coil capacity, and at least one room attached to that coil is in excess of +/- 1.5°F of the thermostat setpoint for that hour.

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 …

Hi. I am working on energy modeling with Trane Trace 700, so I have proposed model and baseline model. Based on the code, I am using the minimum OA for thermal zones in both models with same amount. However, the result from Trane Trace shows me different outdoor air amount in hourly. The total amount of OA is same in Airflow report however, in hour Ventilation chart shows me dramatic ...
