See the answer to this question about the DOE Prototype buildings.

The link you reference is for ASHRAE 90.1-2004, Post-1980, and Pre-1980, not ASHRAE 90.1-2013. Also, PNNL updated the models from the version you referenced: PNNL, Enhancements to ASHRAE Standard 90.1 Prototype Building Models, April 2014. Most importantly, the updated included adding a data center to the Large Office model which explains the much higher EUI. The lower medium office building EUI is explained by the new code version.

Both the PNNL reference buildings and theCreate DOE Prototype Building measure are under active development (e.g. recently switching to ASHRAE 169-2013 instead of ASHRAE 169-2006 for design days), but should be very close.
