Tas Systems Project Wizard and 90.1 Baseline Systems

This guide explains the Baseline systems which are created by the Tas Systems Project Wizard (TPDx). The user will also need a copy of the 90.1 document (ASHRAE standard 90.1, “Energy Standard for Buildings Except Low-Rise Residential Buildings”). The 90.1 document is the basis of the systems described below and is an essential reference for the user. This guide makes very frequent reference to the 90.1 document, and the user will need the 90.1 document in order to determine system inputs, check exceptions, and look up values.

Note: Tas baseline systems are based on the I-P units version of the 90.1 document (i.e., US units).
