Definition
Precisely what quantity this is. Precisely enough that two people measuring independently would produce the same number.
| Field | Value |
|---|---|
| Quantity | |
| Unit | |
| Symbol / short code | |
| Normalisation | <per m², per occupant, per degree-day, per m³ of pool …> |
Why we measure it
What decision does this number inform? A metric that changes no decision should not be collected.
Instrument and method
| Field | Value |
|---|---|
| Instrument | <make/model or class> |
| Installation point | |
| Reading method | <manual, logged, derived from another metric> |
| Frequency | |
| Expected accuracy | |
| Known error sources | |
| Approximate cost |
Conditions to record alongside
The context without which the value is uninterpretable: weather, occupancy, season, system settings, operating mode.
Confounders
What else moves this number that is not the thing we are trying to observe, and how we normalise for it.
Baseline requirements
| Field | Value |
|---|---|
| Minimum baseline duration | |
| Seasonality | <does this require a full annual cycle?> |
| Acceptable fallback | <retrospective from bills, reference site, physics estimate> |
Benchmarks
Reference values to compare a site against, with source and tier.
| Benchmark | Value | Geography | Tier | Source |
|---|---|---|---|---|
Data handling
Where readings are stored, format, retention, privacy considerations if the site belongs to a client.
