Scaler offers a range of normalization options to improve the comparability, consistency, and accuracy of reported consumption data. These are used across Scaler’s platform in dashboards, reports, and exports to ensure that results reflect underlying performance, not gaps or distortions in the data. This document outlines the types of normalization available, where they are applied in the platform, and how they are calculated.
Overview of Normalization Types
Default View (Unnormalized Data)
- Definition: Metrics shown based on all consumption data entered at the meter level.
- Includes: Data marked as “Estimation” under Monitoring method.
- Excludes: Meters marked as Excluded from calculations in the Data Collection Portal.
- Note: Data is not normalized for time, area, occupancy, or weather.
1. Time-Based Normalization
- Purpose: Extrapolates consumption to represent a full calendar year.
- Where used: Portfolio-level Energy Use Intensity and Total Consumption graphs.
- Method:
- For Total Consumption:
Normalized Value = Reported Consumption / % of Year with Data- For EUI:
Normalized EUI = Reported Consumption / % of Year with Data / Active Area
- Alignment: GRESB outlier methodology (resource-level coverage).
2. Occupancy-Based Normalization
- Purpose: Adjusts consumption to reflect 100% occupancy.
- Where used: Portfolio-level Energy Use Intensity and Total Consumption graphs.
- Method:
- For Total Consumption:
Normalized Value = Reported Consumption / Average Occupancy Rate- For EUI:
Normalized EUI = Reported Consumption / Average Occupancy Rate / Active Area
- Alignment: GRESB outlier methodology.
3. Time + Occupancy-Based Normalization
- Purpose: Adjusts for both time and occupancy.
- Where used: Portfolio-level energy graphs.
- Method:
- For Total Consumption:
Reported Consumption / % of Year with Data / Average Occupancy Rate- For EUI:
Reported Consumption / % of Year with Data / Average Occupancy Rate / Active Area
- Alignment: GRESB outlier methodology.
4. Weather-Based Normalization
- Purpose: Adjusts energy use to account for weather anomalies.
- Where used:
- Portfolio-level energy graphs (View > Weather-based normalization)
- When Weather Normalization is enabled in Portfolio Settings
- Method: Uses Heating Degree Days (HDD) and Cooling Degree Days (CDD) to normalize usage against long-term averages of the assigned weather station.
- Application: Applied at the asset level when
allocated weather stationis set under Asset Details.
- Use case: Helps isolate the impact of operational efficiency measures by filtering out weather-driven variability.
Normalization in Reports & Exports
Normalization is also applied in generated reports and downloadable exports to ensure alignment with the timeframe of the report or reporting framework.
Examples:
Monthly Meter Consumption Export
- File: Found in Data Collection Portal > Asset > Meter List > Download
- Column:
actual_monthly_consumption
- Method:
- When consumption spans multiple months (e.g., quarterly or annual meter readings), Scaler:
- Calculates average daily consumption over the interval.
- Allocates this to each month proportionally based on number of days.
Report Generation Normalization
- Scenario: You’ve entered annual consumption but generate a quarterly report.
- Scaler’s Approach:
- Scaler uses the daily average from the interval and applies it proportionally to each sub-period in the report (e.g., quarters, months).
Ownership-Adjusted Normalization
- Use case: An asset’s data overlaps with the reporting year but is only owned for part of it.
- Scaler’s Approach:
- Consumption values are prorated to reflect only the days during the ownership window.
- This ensures only in-scope data is included for frameworks like GRESB.
- For like-for-like comparisons, clients may override ownership settings to retain values.
How to Enable Normalizations
Weather-Based Normalization Setup
- Enable in Data Collection Portal > Portfolio Settings.
- Assign weather stations to each asset in Asset Details.
- Populate average HDD and CDD values.
Viewing Normalized Data
- Go to Analytics Portal > Portfolio View.
- On energy graphs (EUI or Total Consumption), select normalization method from the View dropdown.
- A green "Normalized Data" badge will indicate that a normalization method is active.
Why Normalization Matters
Normalization enables apples-to-apples comparison across:
- Assets with partial-year data
- Assets with variable occupancy
- Assets in different climates
- Periods impacted by abnormal weather
By controlling for these variables, Scaler provides clearer insights into operational efficiency and performance trends.
