Zero Tool for Portfolios is a bulk upload and export feature that generates baselines for an entire portfolio of buildings in a few simple steps. To use the Zero Tool for Portfolios, gather basic information about your buildings (locations, primary use types, and floor areas) then follow these steps:
- Download the Zero Tool for Portfolios Template CSV file.
- Copy & paste or enter building stock data into the proper columns, following the format of the examples included in the template and shown below (delete the example rows when no longer needed for reference, but be sure not to delete the first row with column headings.)
- Column A, Building ID, can be any unique identifier for the building (e.g. address or parcel ID number).
- The text in Column D, Primary Building Use, cannot contain spaces. For a list of supported and properly formatted building use names, download the Zero Tool Building Use Names Excel file.
- Note that only CSV files are supported, so when saving do not change the file format. Changing the file name will not affect the output.
- Once properly formatted, click the Upload CSV button. Navigate to and select the completed CSV, then click Submit.
- Upon successful submission the Submit button will show a processing wheel graphic. Once processing is complete a Results folder will be downloaded automatically. The Results folder will contain the uploaded CSV, a Results CSV of all of the successfully processed entries with their corresponding baselines (baseline Site EUI, baseline Source EUI, and Zero Score of 100), and an Errors CSV logging unprocessed entries, if any.
- If errors occur, reformat the necessary entries and re-upload the spreadsheet.
The Zero Tool – an Architecture 2030 project – was developed for building sector professionals to establish energy reduction baselines and targets, compare a building’s energy performance with similar buildings and to codes, and understand how a building achieved its current energy performance.
Architecture 2030, in offering the Zero Tool, accepts no responsibility or liability for the accuracy of the baseline and target data estimated by the Zero Tool, or for the design of buildings utilizing Zero Tool baselines and targets. The underlying assumptions and methodologies of the Zero Tool are based on those developed by EPA’s ENERGY STAR program, and are intended to serve as guidelines when setting performance targets and understanding (relative) building performance.
