To support the ASHRAE Building Energy Quotient(bEQ) standard, the ASHRAE Research 1771 is trying toidentify baseline building energy models for majorcommercial buildings so that the modeled source EUI isclose to the median source EUI of the same type ofbuildings in the 2003 CBECS data. This paper introducesthe procedure of creating a baseline model for the autoservice and repair shops as they account for 2% quantity,0.3% total floor area, and 0.2% energy consumptionamong the commercial buildings. First, we introduced amethod to create the geometry model using the datacollected from the 2003 CBECS data, reports, andexisting building samples. Then a systematic approach isdeveloped to identify the model inputs unrelated togeometry. Ultimately, the baseline model of auto serviceand repair shop is validated by using the median sourceEUI from the 2003 CBECS data. The results indicate thatthe relative errors between the source EUI of the newmodel and the median EUI from the 2003 CBECS datais 12.33%.
