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

VRF Performance Curve Set

Hi Everyone,

This may not be the right place to post software-related questions. But, I wanted to know whether LEED has anything to say about selecting the Performance Curve Set if that data is not available from the supplier, or if that does not match the Performance Curves available in the software?

I'm modelling an air-source VRF system on IES-VE which has limited options for selecting a performance curve. The data of those curves is not editable, nor viewable. Has anyone achieved compliance using IES-VE for modelling a VRF system?

Any thoughts are appreciated!

Hi Junaid, did you figure out anything on the performance curve sets? Its a question I guess every energy analyst has while performing energy modelling. Since it is next to impossible to get the manufacturer performance curve sets or coefficients.
