We have several high rise residential projects that use a several conditioning and ventilation system.

I would like some clarification on how to calculate recycled content as the v4 Reference Guide is ambiguous, in my opinion. For example, on p.274 of the ID+C ref.

I'm working on an appeal and the reviewer is asking me why our baseline heating went up significantly between the initial submission and our review response model.

After two rounds of review our model was denied because according to the reviewer’s comment it still “it remains unclear whether the energy savings modeled for space heating are justified”.

Does anyone know if the Exemplary Performance option for BD+C given for sharing energy data via a Third-party template is available for ID+C? I haven't seen anything about it either way.

Can natural ventilated stairs and lift shaft excluded from requirements of this credit? If not, how can these spaces comply with this credit?

Hi, we have development where the Chiller Plant is serving three buildings.

Dear all, We are assessing a renovation project according to LEED v4.

Does anyone know if non-potable systems are included in the scope of this credit? I am referring to gray water, stormwater, water treatment plant and irrigation systems. Thanks

It's unclear where GRI-checked reports fall under the credit requirements - would they be considered self-declared for 1/2 value or third-party verified for full value?
