Overview
For each month of energy data, PropScore records how the figure was obtained as 「データ取得方法」. When emissions are calculated, it shows, per property-year, the share produced by estimation as 「推計割合」. 「GRESBエクスポート」 uses these two to check whether any property-year breaks GRESB's rules.
Data provenance values
| Label | Meaning |
|---|---|
| 「実測」 | A meter reading or invoice covering that month only. |
| 「請求期間按分」 | An estimate that spreads an invoice covering several months across those months. |
| 「前期実績流用」 | An estimate carried over from an earlier month or the same month of the previous year. |
| 「床面積按分」 | An estimate that divides a measured whole-building figure by floor area. |
| 「不明」 | The provenance was not stated. |
Every month that is not 「実測」 counts as an estimated month, and so does a 「不明」 month.
How data provenance is recorded
Data provenance is written per month in the データ取得方法 column of the energy data CSV file.
For a file without a データ取得方法 column, and for rows where that column is blank, the choice made in 「このファイルのデータ源」 at import time — 「不明 — 申告しない」 or 「すべて実測 — 検針票・請求書に基づく」 — is used.
「このファイルのデータ源」 starts at 「不明 — 申告しない」.
Importing the same month of the same property again also replaces its data provenance and estimation note with the new file's contents.
The 「データ取得方法」 and 「推計理由」 columns on a property's 「エネルギーデータ」 tab are display-only and cannot be changed on screen.
Editing a value in the table on the same tab does not change that month's 「データ取得方法」.
Estimation note
A month that is not 「実測」 needs an estimation note.
When the estimation note is blank in the CSV file, PropScore records 「推計理由が記載されていません（データ取得方法: {値}）」 or 「行ごとのデータ取得方法が未記載のため、インポート時の一括申告（{値}）を適用。」 as the note.
{値} holds an English value such as unknown.
A month with no data shows 「不明」 under 「データ取得方法」 and 「理由の記載なし」 under 「推計理由」 in the table.
For a 「実測」 month, 「推計理由」 shows 「—」.
Estimated ratio and estimation method
The estimated ratio is the number of months left after subtracting the 「実測」 months from 12, as a share of 12 months. Months with no data also count as estimated months. The 「推計割合」 column on the 「排出量」 screen shows the ratio to 1 decimal place, with the estimation method below it.
| Estimation method shown | When it is shown |
|---|---|
| 「推計なし（全月実測）」 | All 12 months have data and all are 「実測」. |
| 「入力値が推計」 | All 12 months have data and at least one month is not 「実測」. |
| 「期間按分（GRESB禁止）」 | Fewer than 12 months have data and they were scaled up to a full year. |
| 「用途別原単位（GRESB禁止）」 | No month has data and the figure was estimated from per-use-type benchmarks. |
How this relates to GRESB's rules
「GRESBエクスポート」 checks each property-year against the following four rules, and if any property-year matches even one of them, it does not export the workbook.
- R1: the estimation method is 「期間按分（GRESB禁止）」 or 「用途別原単位（GRESB禁止）」.
- R2: the estimated ratio is above 20%.
- R3: the estimated months of the chosen fiscal year and the previous one (the estimated ratio times 12, rounded) add up to more than 3.
- R4: emissions have not been calculated for that fiscal year.
A property-year without all 12 months of data matches R1. Even with all 12 months, a property-year with 3 or more months that are not 「実測」 matches R2.
「この確認で保証されないこと」
Next to the check result, the 「GRESBエクスポート」 screen shows the following four points under 「この確認で保証されないこと」.
- A month entered as 「実測」 is not counted as estimated even if its figure was really an estimate, so the estimated ratio can come out lower than it really is.
- Passing the check means that no violation was detected; it is not proof of compliance.
- Months imported from a CSV file without a
データ取得方法column cannot be told apart as measured or estimated. - The two-year cap is evaluated only on the previous fiscal year's data held in PropScore, so it can be undercounted.
