This webinar will focus on the software features known as calendarization and normalization: 

    • How EnergyCAP calendarizes utility bill data 
    • Identifying and adjusting for weather sensitivity 
    • How EnergyCAP normalizes utility bill data 
    • The difference between calendarization and normalization 
    • The normalized long-term Energy Use Index (BTU/Sq Ft trend) 
    • Is normalization a form of Measurement & Verification? Does it comply with IPMVP?

Cost Avoidance - Calendarization and Normalization Slide Deck

(recorded December 21, 2016)

Webinar Questions & Answers

  1. Could you please show again how you can get 5 years of data for one commodity using the cal28 report?
    1. The CAL28 report does not provide 5 years of data, it is limited to 24 months. The NORM05 report was the report used to display 5 years of history.

  2. Can you provide the presentation from session 1?
    1. Slide decks for each webinar are available at the documentation page for the corresponding webinar (e.g. Cost Avoidance #1: M&V Fundamentals)

  3. What would be the best way to determine the best balance point temperature to use for a national retail client? As many buildings have different energy efficiencies, how do you determine a standard to use for all the buildings that the client owns?
    1. In general, a 55F balance point will give better results than 65F and is a good national standard, assuming relatively new and efficient buildings.  If the building stock tends to be older, I’d recommend 60F.

  4. Why would you calendarize interval data? Aren't the data already in the right day/month?
    1. I do not and would not calendarize interval data. But interval data can be used to more precisely calendarize monthly utility bill data, although EnergyCAP does not have this functionality currently.

  5. It looks like we have to select a balance point temperature for an entire campus. Any guidance on selecting a whole-campus balance point? (Our campus is probably somewhere around 45F)
    1. We recommend 55F as a global normalization setting.  When using the much more precise cost avoidance module (see webinar 4Jan17), you can tune each meter’s balance point independently.

  6. What are those engineering analysis tools for multiple independent variables? Could you please name those?
    1. I have not used multiple regression tools other than Excel.  I am not aware of what may be available on the market.  Since it is such a specialized niche, I would not rely on packaged software but would use Excel.

  7. How would you weather normalized data for added 75,000 sq ft and increased number of occupants by 7% as well as increased operating hours by 9% in addition ti weather degree days?
    1. During the webinar, it was explained that the Normalization module does not handle variables other than weather (degree days).  The Cost Avoidance module (Jan 4 webinar) allows the user to enter adjustment factors, called Special Adjustments, for variables such as number of occupants, occupancy hours, new equipment, etc.  It also makes automatic adjustments for floor area changes.

  8. Can you show district wide normalization data?
    1. Yes, just click on any roll-up node in Buildings & Meters and use the Normalized Data tab, or run a NORM report.
