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?

It appears as if there is some explanation in Section 6.4.1.2.1. There might be more in the User's Manual.

The main difference is that Path A has slightly flatter kW/ton efficiencies for full load and part load, whereas Path B has criteria for a worse full load kW/ton but a much lower than Path A part load kW/ton efficiency.
