Performance Metrics
The following section outlines the way monthly and annual performance metrics are calculated. The diagram below shows how data is rolled up from meters associated to a specific space type to provide higher-level performance insights.
Methodology
1
All water meters associated with a space type are collected
- For whole building performance metrics all in-metric meters are used.
2
Meter consumption is normalized into common units & calendar months
Consumption entries between meter activation & deactivation dates and property buy and sell dates are broken down and reconstituted into monthly values for each meter. Data outside of these boundaries is ignored.
3
Monthly consumption values are aggregated by meter type & subtype
Meters are grouped by subtype to enable performance metrics at multiple resolutions.
Water Meter Subtypes
Water Meter Subtypes
- Potable - Mixed
- Potable - Indoor
- Potable - Outdoor
- Reclaimed - Mixed
- Reclaimed - Indoor
- Reclaimed - Outdoor
- Well - Mixed
- Well - Indoor
- Well - Outdoor
4
Monthly consumption data is aggregated over rolling 12-month periods
For every subtype, monthly normalized values are rolled up to provide monthly & annual metrics for every possible 12-month reporting period.
5
Values are further rolled up into portfolio-level insights.
Monthly and annual consumption values are aggregated across all properties to enable portfolio-level views.
