Hi everyone, sorry if this is a bit obvious, it is my first time working with this type of LEED certification. I am working on a refurbishment project for an office space, I have made my energy model with the specifications given by the design team and created a baseline model, but what I would want to know is which aspects of this baseline model remain as the proposed one and which change to the ones specified in the ASHRAE Standard. As an example, as you know when working on a BD+C model the baseline uses the ASHRAE requirements for all the elements of the envelope, the HVAC system, lighting etc as well as simulating energy loads for four different orientations. It makes sense to me that in this case there is no need for the simulation in different orientations as the existing building could not hypothetically be rearranged in a different way anymore, and if the envelope is not being modified from its original form, it would have the exact same characteristics in the two models, and we would have to assess how much energy we can save with the new HVAC system, new lighting and new internal partitions we are proposing. I just want to know if our logic is sound here. Thank you very much for your help.
