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..png?fit=max&auto=format&n=W9COhIzjFYd7p3yh&q=85&s=d8b8f53728396816fa90af708f786cf6)
Methodology
1
All energy 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.
For bulk delivery energy meters (e.g. Fuel Oil), all energy associated with the entry is attributed to the month in which the fuel was delivered.
3
Monthly consumption values are aggregated by meter type & subtype
Meters are grouped by subtype and higher-level types, to enable performance metrics at multiple resolutions.
Energy meter types and subtypes
Energy meter types and subtypes
| Subtype | Type |
|---|---|
| Electric | Electric |
| Electric on Site Solar | Electric |
| Electric on Site Wind | Electric |
| Natural Gas | Fuel |
| Diesel | Fuel |
| Fuel Oil No 1,2,4,5,6 | Fuel |
| District Steam | DHC |
| District Hot Water | DHC |
| District Chilled Water | DHC |
4
Monthly consumption data is aggregated over rolling 12-month periods
For the whole building and every meter type and 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.
