Welcome to the Energy Twin (ET) extension for SkySpark. Energy Twin is a machine learning-based SkySpark extension for energy data analysis and prediction.

There are three ET libraries available on StackHub:

  • ET Analytics
    • advanced ML library using detailed models with up to 15min sampling
    • ideal for building electrical energy consumption analysis and prediction
    • anomaly detection - predefined Sparks
    • tailored KPIs
    • based on the TOWT model by LBNL
    • free to download, licensed by ET Core
  • ET Interactive
    • simple to use regression analysis using degree-days models and ASHRAE change point models
    • interactive model tuning and outlier removal
    • perfect for heat consumption analysis
    • free to download, licensed by ET Core
  • ET Core
    • core mathematical modeling algorithms referenced by both ET Analytics and ET Interactive
    • ET licensing mechanism for both ET Analytics and ET Interactive

See the ET website for case studies and more information: Energy Twin webpage.

ET Licensing

  • ET license is valid for both ET Analytics and ET Interactive
  • ET license is defined by two parameters:
    • expiration date
    • the maximum number of models that can be defined at one time (see the explanation of a model below)
      • the maximal number of models is calculated across all projects on the SkySpark server
      • the sum of the models that are defined in ET Analytics and ET Interactive is evaluated
  • What is a model?
    • ET counts models in a similar way to SkySpark license points
    • each model is linked to one point
      • typically a kW point of a meter
      • one model usually equals one meter
    • model can be re-linked to any other point and re-trained anytime
  • Ask ET sales (-----------------------------) for an individual offer or start with one of the two predefined starter licenses
    • Starter 6 x 12
      • use up to 6 models for 12 months
    • Starter 72 x 1
      • use up to 72 models for 1 month
