In the Extended Project Data section, the baseline for US and Canadian projects will be automatically calculated based on the Zero Tool, but custom baselines may be input instead. After use type(s) and associated square footage are entered, the DDx will automatically calculate a baseline based on the Zero Tool, along with a target. You may then either choose the default baseline, or enter your own pEUI baseline and and source information before saving.
Zero Tool
Architecture 2030 developed the Zero Tool so that regional average Baseline EUIs for projects could continue to be calculated using CBECS 2003 once EPA’s Target Finder calculator switched to the 2012 CBECS. For consistency of reporting for the AIA 2030 Commitment program, and to reduce potential “baseline confusion”, the AIA 2030 Commitment has incorporated the Zero Tool with the DDx as the recommended approach to define project baselines. The Zero Tool replicates, as well as streamlines, the calculation procedures that were used by ENERGY STAR Target Finder.
