Hourly Methods Approach & Testing Considerations

Week Eleven CalTRACK Update

Week eleven was the first week of hourly methods discussion. Developing hourly methods will require discussion and empirical testing of topics unique to hourly methods before we can make final specifications.
Topics that must be addressed include:

• Data sufficiency requirements
  
• Modeling approach
  
• Model selection criteria
  
• The effect of aggregating hourly models on portfolio uncertainty
  

Time Of Week Temperature Models (TOWT):
A proposed model for hourly methods is the TOWT model from Lawrence Berkeley National Labs (LBNL) is shown below.

Notes:

1. The number of temperature ranges and the balance points will need to be defined. The LBNL model had 5 ranges ( < 55F, 55-65 F, 65-75 F, 75-90 F,  90 F <).
   
2. The methods for defining if a building is occupied or not is explained in detail in Phil Price’s  Everything I Know About Building Energy Modeling, But Never Told Anyone Before (18:30-30:00).
   

Homework:

1. Use Hourly Method Tools on test data
   
2. Report findings on Github
   
3. Offer test criteria for hourly models
