Impact of the Representation of Interior Loads on the Calibration of an eQuest Energy Model for a Case Study

Andreea Mihai, Radu Zmeureanu

Abstract: This paper explores two different approaches for the representation of hourly interior loads for the calibration of an eQuest energy analysis model. Approach A uses the profiles of internal gains from the ASHRAE 1093-RP. Approach B uses a simplified step-change profile calculated based on derived measured cooling load profile for each thermal zone. The results show that the model is calibrated for all zones in terms of indoor air temperature, regardless of what approach is used for defining the internal loads. In terms of air flow rate, the model is calibrated for nine zones out of fifteen by using the approach A and eleven zones by using the approach B, when statistical indices are used for comparison. Only five zones are considered calibrated using approach A and six zones using approach B, when the statistical hypothesis testing is employed.
