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

@DC_88 According to DesignBuildr's LEED and ASHRAE 90.1 Appendix G User Guide available at: https://designbuilder.co.uk/downloads...

"Note: For ASHRAE 90.1 2010 and later, there is an exemption that allows the baseline simulations to be run without rotation if certain criteria for window-to-wall ratios are met. This exemption is handled automatically by DesignBuilder (see Figure 80)..."

@DC_88 If this does not clarify the issue, please send the model with a description to the DesignBuilder's support desk at https://support.designbuilder.co.uk/s...
