Multiplying Capacities? when using Multipliers

My question : I am working on a midrise residential tower. I added multipliers on the thermal tab. I also multiplied the capacities for my Heating, Cooling, and Airflow rates. When I check my proposed model outputs compared to the baseline outputs, I can see that the energy consumption (on cooling) for proposed is several times higher than what is shown on the baseline model. I am thinking it has to do with the capacities being multiplied. I multiplied the capacities due to what I read on the "tips and tricks for energy plus document" [page19-20]. I thought that is what it said to do, but I might have misinterpreted what it said. Any insight on this would be much appreciated.

Thank you for responding. I just switched all my inputs to auto size. I now see that my cooling output is higher. so that makes me think that its not the increased capacity inputs. I did not include the height variations. I modeled them on top of each other with adiabatic surface adjacencies. I did add the multiplier count on the thermal tab. But now I am thinking the increased capacity might not be the issue. So I am thinking I am supposed to multiply the capacity inputs for Cooling, Heating, and airflow as well as add the multiplier count. Thanks
