G3.1.2.8 Design airflow rates

I have a question regarding section G3.1.2.8 of Appendix G. This section says that "design supply airflow rates for the baseline building design shall be based on a supply-air-to-room-air temperature difference of 11C". If I understand it well, for cooling mode if the room temperature is 24C then the supply air in the AHU should be 13C. The max supply air temperature, based on section G3.1.3.12 Supply Air Temperature Reset in this case should be 15.3C (13C+2.3C) - is that correct? And what about the heating mode? If the room temperature for system 5 and 7 is 21C then according to section G3.1.2.8 supply air temperature in the AHU should be 32C (21C +11C)? If this is correct then in our case the reference building will be using much more energy for heating than the design case.
