Hi, I am modelling a 6 storey office building which also has a basement car park. The basement car park is is naturally ventilated and also consists of a few small storage rooms, IT rooms and a security room. Under this current LEED effort we will be construction some showers in the basement. My question is should I also assign the ASHRAE Baseline system to this basement level of the building in the ASHRAE 90.1 energy model ?
