I'm doing a simulation for LEED and I already read the Appendix G of ASHRAE 90.1. It did not seem necessary to perform an energy cost analysis in the simulation, only an energy consumption analysis. However, reading the regulation of LEED, I see that it requests this cost analysis in the simulation.
Then I ask:
1) Is it really necessary a cost analysis between the baseline and the proposed model in a simulation to be submitted to the USGBC?
2) Is it possible enter the full energy cost data in OpenStudio? If so, how?
