Is it a must to start a simple box energy model for a new project to extract HVAC requirements to acheive a certain level of energy savings?
Oe is there a guide that can be used to extract preliminary requirements at this early stage?

It is not a must. A simple box model actually is required under the Integrative Process credit. The modeling required for this credit would typically happen after you do a simple box model very, very early in the design process.
The best guide to design phase energy simulation is contained in ASHRAE Standard 209.
