You are modeling a Highrise Residential project and have failed to input the correct number of stories for this occupancy type. Highrise residential projects are considered four stories or more.
At the Zone level of the tree, review each entry for the Floor Number input. You must ensure that this is set to four or more. If your project is in fact less than four floors, you need to change the Zone Occupancy input to Multi-Family and run the Res T24 Performance calculation instead.
