Hi all,
I and my team are working on LEED v4 BD+C project, and we're looking to pursue the Integrative Process credit for Core and Shell certification.
We have an existing building where we will do complete renovation. To evaluate energy loads reduction strategies we will model the simple box of existing building and then we will implement the best strategies to improve the energy performances of the building. It is correct or do we model The Proposed Building also? Or it is enough the description of strategies?
In the simple box is it necessary to include the HVAC system? Or only the envelope must be modeled? As in this conceptual phase of the project, the real HVAC has not yet been defined, If HVAC system is necessary is it possible to model an ideal HVAC System?
Thank you so much

You can't run a model without an HVAC system so you have to enter one that is auto-sized with many defaults.
You need to evaluate two strategies within each category listed. You can't just evaluate the building envelop. How you evaluate them is up to you. If you are evaluating "savings" you can't do that without some sort of baseline model. There are other ways to do this that would likely qualify.
