Impact Profiles

Load Shapes Library & Tool

CEDARS now supports creating Impact Profiles derived from uploaded deemed load shapes.

This release introduces the first MVP version of the Load Shapes Tool, focused on supporting draft measure package development and Impact Profile generation for cost effectiveness analysis. Future enhancements will continue to improve performance, visibility, and usability.

The Load Shape Tool can be accessed via the Cost Effectives Tool (CET) module > Impact Profiles & Load Shapes.

What's New

For Program Administrator Users

  • Select draft measure packages synchronized from eTRM.

  • Upload 8760 deemed load shape data.

  • Validate load shape files against measure package metadata and permutations from the eTRM.

  • View upload history and QC summary of uploads.

  • Add load shapes to the Load Shape Library.

  • Generate Impact Profiles from uploaded load shapes.

For All Authenticated Users

  • Browse the Load Shape Library.

  • View load shape derived Impact Profiles.

  • Use published Impact Profiles derived from load shapes in CET runs.

How It Works

  1. Draft measure packages are synchronized from eTRM to CEDARS each evening.

  2. Users select a draft measure package and review the permitted permutation values.

  3. Users upload associated 8760 load shape files.

  4. CEDARS validates the uploaded data against the measure package configuration.

  5. Successful uploads are added to the Load Shape Library.

  6. Users generate Impact Profiles from successful load shape uploads.

  7. CEDARS automatically calculates avoided costs.

  8. Published Impact Profiles become available for use in CET the following day.

Select measure package and view allowed values for the 8760 upload.

8760 Load Shape Files

Load shapes files will be generated by EnergyPlus building simulation models in the correct format to be uploaded to CEDARS. A load shape provides normalized unit energy consumption for every hour of one year for a total of 8760 records per load shape.

New load shapes submit to CEDARS are identified by the fields:

  • BldgType

  • BldgVint

  • BldgHVAC

  • TechID

The buildings and technologies in the load shape file must match the draft measure data for the measure package selected for the upload. PAs may upload load shapes for subsets of the technologies in a measure package, or for all technologies.

CEDARS requires 8760 files to use explicit BldgType and climate-zone-specific BldgLoc integer values, even when the eTRM permutation contains "Any". Uploaded values will be matched back to the applicable "Any" permutation during processing. BldgHVAC may still use "Any" in uploaded 8760 files. View Example File

Users can generate impact profiles from uploads that pass all validation checks
Load Shapes are automatically added to the library, where you can view the daily consumption profiles.
Generated Impact Profiles are added to the library, to view you can filter by Load Shapes

Benefits

This feature streamlines the process of developing and testing draft measures by providing a direct workflow from eTRM measure package development through to Impact Profile generation and CET evaluation within CEDARS.

Documentation

User guides and supporting documentation for Load Shapes, including upload requirements, validation rules, and processing logic, are currently being finalized and will be published in CEDARS shortly.

ℹ️ Future enhancement: A dedicated Measure Developer user type is currently under development. This role will provide access to the Load Shapes workflow without requiring broader Program Administrator permissions.
