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?

DESIGN AND CONSTRUCTION PRELIMINARY REVIEW

Excuse me, in the supply airflow rate part, it is required that the airflow should be approximately 1 cfm/square feet for the office buildings. Would you please tell us how it is calculated please?

Our project is a conference room and its height is 9.8 feet, so we wonder if the requirement is suitable for our project. 

Thank you.

1 cfm/square foot is a general rule of thumb, not a requirement. The supply airflow of the Proposed model must be modeled consistent with the actual design, and the Baseline supply airflow should be sized by the software using a 20 degree F supply-air-to-room-air temperature difference per G3.1.2.9.
