CS v3 - Appendix 4 - Tenant Lease or Sales Agreement

Maya, I would interpret the information in Appendix 4 Case C to mean that your team would be required to ensure ETS separation according to Case 1 Option 2 via a legally binding agreement with the building tenants.

Appendix 4 is not clear on whether tenant spaces need to comply with ASHRAE 90.1. Please clarify.

Tenant spaces would only be required to comply with 90.1 in so far as their space was completed within the core & shell scope. Any tenant fit-out remaining after the core and shell was complete wouldn’t be required to meet 90.1.

I don't have direct experience with this, so I have to make that caveat.But according to my reading of CS Appendix 4 and my general understanding, it's not referring to a path for ID points or even a substitute, it's referring to a compliance method for regular credits. In cases where compliance with the credit would rest to significant degree on what the tenant does, binding language directing them to meet the LEED-CS requirements would be accepted as documentation for the LEED-CS credits.One exception to what I just said—at the end of the appendix, there is a note about how EP points can be earned through some specific credit paths.

Tristan, We are having some problems with a client that do not want to certify LEED-CI its interiors and leased a floor in a LEED-CS certified building. The owner is requiring that the projects comply with ASHRAE what is increasing a lot the project budget and our client do not have enough money. Does owner impose us to meet ASHRAE 90.1? As per your previuos comment we understand that he can not.

Fabiano, read CS Appendix 4 and tell me what you think. It appears that you must include tenant space in consideration for EAp2 for CS projects. This implies some control over what the tenant does in their space relative to ASHRAE 90.1, etc.
