Yes you can use the fan power calculator if using Appendix G.It appears to be the same in Section 11 but I am not certain of that. For a Section 11 model I think you are a System #9 but I have not applied that section in a very long time. See Figure 11.3.2. For Appendix G you are a system 4. There are no VRF baselines.
