Defining consistent and relevant baselines is important to establishing meaningful benchmarks to track progress and compare performance. The 2030 Commitment uses CBECS 2003 (Commercial Building Energy Consumption Survey) and RECS 2001 (Residential Energy Consumption Survey) as the baseline energy use intensity (EUI) for whole building projects, measured in IP units of kBtu/ft2/yr and SI units of kWh/m2/yr. (See Set a Project Baseline (Interiors only) for more on LPD). These baselines were set at the onset of the 2030 Commitment because they were the best available US data sets.
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 area 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.
