You are trying to run a Nonresidential Calculation for this project, but it appears you have no valid Zones/Rooms entered that are designated as valid Nonresidential occupancy types.
Begin by checking each Zone for a valid occupancy type. Below each Zone, verify that you have entered a square footage for each of the Rooms.
If you did not intend to run Nonresidential Calculations, you need to uncheck the option to run this calculation. Click on the Calculations button on the bottom left. Above this button a list of calculations will appear. Find the calculation in this list and uncheck the box that tells EnergyPro to run the calculation.
