Hello Angela!
My name is Beth, and I am serving as the C2C monitor this period. Thanks for your question. You've done prior research, and the Conserve-O-Gram was one of the resources I would have shared with you. If possible, I would try to inquire about the specific materials being used. The period of off-gassing may vary for different adhesives and carpet materials. However, if you want to present a plan, generally, I do think allowing for a longer time frame before installation and resourcing a HEPA unit would be good ideas. Anecdotally, at my own institution, we allowed a few months after a renovation in an exhibit area before installing. As you don't know what specific materials are in the carpet, I would err on the conservative side and follow the "at least four weeks" suggestion. I assume there may be painting, case installation, and other work that will need to be done in that area as well during which you'd want an empty gallery. Since you've looked around, I will share a few resources but know you may have already found them. Most indicate avoiding carpet, and so do not give off-gassing parameters, unfortunately.

https://www.canada.ca/en/conservation-institute/services/preventive-conservation/design-considerations.html -- This indicates at least four weeks four weeks within airtight spaces, which your room may be considered, depending on your HVAC. You might be able to discuss the turnover of the air within the room with your building manager, and see if that can be adjusted during the time the space is waiting for installation. In the resource, the recommendation is for painting and sealants, not carpet and related adhesives.
As for the question regarding raising the temperature to help evacuate VOCs, I do not see this information readily, though the sources above state to control humidity during off-gassing.
I wanted to respond to you quickly, but I also will check a few other resources tomorrow.
Best,
Beth
