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

How to report High COP values for Chillers

Hi I am working on a Data Center in Chicago, and we have Chillers which have a high COP when the ambient temperature is low outside, so The energy modeling software that I am using can ony get as high as a COP of 50 but there are close to 2000hrs in a year in chicago where the temperature is below freezing and we are getting high COP of more than 50 how can I report thoise savings?

 

TIA

The chillers should be modeled with the rated efficiency. The increased performance at low outdoor temperatures would be accounted for within the modeled performance curves.
