A proposed model was created in DesignBuilder and thereafter a baseline model was created with the help of DesignBuilder in-built baseline creation tool. Accordingly, a baseline HVAC model was also created. However, when the interface for baseline creation was being clicked, it shows "Calculate baseline building without rotation" under ASHRAE 90.1 Baseline Simulation. This optioned is ticked and is greyed out. However, in other models, as user choice is given whether to perform rotated baseline simulation or fixed orientation simulation. Kindly anyone help in this regard
