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?

Exception c requires that lab spaces use a system 5 or 7 in the same way that exception d does, but exception c does not prescribe any specific turn down during unoccupied periods. Does this mean i can force the baseline to be constant volume at the design air change rate assuming my air change rate is higher than the required airflow to handle the load?

No. That particular requirement was moved to the exception under G3.1.3.13 for lab spaces.
