automatic daylighting controls and occupancy sensor are adapted into the project, and many other energy saving measures included,i do not simulate daylighting control and occupancy sensor in the energy model for the first submittal, because my project requirement is just 10% cost saving and i achieved 14.3% cost saving by other energy efficiency strategies.
the reviewer comments require that i provide a narrative describing the controls and how they are implemented in the Proposed energy
model. can i answer " i did not model automatic daylighting controls and occupancy sensor in the energy model based on my project certification goal?

You are required by Appendix G to model the project as designed which includes all of the strategies in the design (Table G3.1-1). Your percent savings goal really has nothing to do with the issue so I would not even bring it up.
Even though you are required to model the project as designed/constructed, you are permitted to exclude certain design features if you can demonstrate that not modeling them results in a conservative estimate of savings. In other words you are just hurting your savings so that is typically allowed.
So I would just explain the the reviewer the lighting controls and how they were modeled. Make sure you have properly addressed any control issues which are also mandatory provisions (like 9.4.1.2) as these are required no matter your percent savings.
