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

Energy Twin 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
• ET Evaluation
  • additional tool for ET models’ prediction evaluation
  • free to download, operates only with models from ET Analytics and ET Interactive
• ET Common Tools
  • necessary package containing common functions used by all extensions

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
