CS-2009 EAp2: Minimum Energy Performance
We are pursuing Option 1 (Whole Building Simulation). In the Proposed Case we modelled the part load performance of the chiller based on the part load performance values (fraction of Full-Load Power values) at Fan Part-Load Ratio of the manufacturer datasheet.
It is unclear for me how to determine the part load performance for the Baseline Case as I could not find respective values (e.g. COP at 25/50/75%) or a graph as provided for the VAV system in G3.1.3.15.
Any ideas?

A portion of our building envelope is historic. Can we exclude it from our model?
For an existing building, do I need to rotate the model?
Our process load is higher than 25%. Do we have to justify that?
Our local code references ASHRAE 90.1-2010. Should I use that for my documentation, or 90.1-2007?

Use the default curve in the software for the type of equipment you are modeling in the baseline.
