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?

How to Model Units that are sized for Dehumidification in Labs

Hi, 

So I am working on a Lab LEED project and majority of the units are sized for lower SA temp in the range of 48-50 F, because of the dehumidification required by the lab. But when I am modeling the baseline we need to supply 55F with 5 F reset. How should I model those units in baseline?

The Baseline lab systems should be modeled as System 5 or 7 (assuming G3.1.1 exception c applies) with a supply air temperature difference of 17 F based on the exception to G3.1.2.9.1. The humidity control setpoint should be modeled identically to the Proposed design.
