FAQs about EAc2 :

The energy cost offset from onsite renewable energy cannot be used to demonstrate compliance with the prerequisite. Can this cost offset still be credited to the proposed energy cost savings for this credit?

Preparing concept HVAC requirements

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.
