The AIA 2030 Commitment uses CBECS 2003 (Commercial Building Energy Consumption Survey) and RECS 2001 (Residential Energy Consumption Survey) as the baseline energy use intensity for whole building projects. Interiors projects are baselined against ASHRAE 90.1 2007 lighting power density (LPD) values. These baselines were set at the onset because they were the best available US data sets.
Experienced 2030 Commitment reporters recognize that there are different approaches to establishing baselines, which can cause confusion. The intent of this guide is to clearly define a recommended process for establishing baselines, and provide guidance for situations with particular challenges.
Step-by-step guide
To set up a project baseline:
- After completing the "Extended Project Data Section" click on "Configure Use Type"
- In the "Configure Your Use Type" section select use type, enter project area then click on "Define Project Baseline"
- In the "Baseline Energy Use" section, enter the baseline EUI and source if you have them. If you don't have the baseline and source, the system will calculate the baseline based on the CBECS 2003 data and rationality.
- Click "Save" or continue by clicking "set target energy use".
- At any point, you can click on the 'back:' button to go back to the previous section and make any changes.
