FAQs about EAp2 :

Do the required savings for this prerequisite (and credit) need to come only from building energy, or also process loads?

Our project doesn't have enough energy savings to earn the prerequisite. Can we get there by incorporating onsite renewables?

Our proposed design has insulation R-values that are below those prescribed by ASHRAE 90.1-2010. Can we still meet the prerequisite?

NC-v4 EAp2:Minimum energy performance

Towers as part of a single building

A building is composed by three towers that have the basement, the ground floor, and the first floor in common. The system for the baseline model shall be System 8. According to G3.1.1 “each floor shall be modeled with a separate HVAC system”. Anyway, since the second floor (and the third one, the firth one…) of a tower has nothing in common with the second floor of another tower, I would consider modeling separate HVAC systems for the 2nd floors of every tower a reasonable solution. Do you agree?

I think it would probably be acceptable as it makes some logical sense. The only reason to not do so it that it is not the conservative approach. The fan power in the baseline will be higher with a series of small systems than it would with a single larger system.
