Performance Indicator Data Sources - Water
This page explains the logic behind how data is assigned to GRESB fields in the GRESB Asset Summary for Water fields. This information is also available as a column in the GRESB Asset Summary dashboard.
All activity data is populated to align with the selected reporting period and floor area unit of measures defined in the GRESB Group Settings page. It’s recommended that you review your settings before assessing data quality, requesting validations or submitting data to GRESB to make sure GRESB and Envizi settings are aligned.
For all activity data (kWh of energy, tonnes of CO2e, m3 of water and tonnes of waste) see Tags and Location Settings to learn about how Envizi summarizes data for reporting.
Data requirements for the Water performance indicator is similar in structure to Energy. The only difference is that Water does not have a breakdown by data type as energy does (eg. fuel, DH&C, electricity).
The water table below has 4 main sections.
First is data availability which is based solely on the the months of data captured or accrued in Envizi.
Second is whole building reporting which will populate floor area coverage and max floor area based on recorded asset size.
Third is sub-building space reporting which uses location settings captured in the Floor Area Coverage pages if available.
Finally water consumption that occur outside of the sub-building space are reported if relevant accounts or meters are explicitly tagged.
Floor areas for water use the same location settings configured in the Reporting Characteristics tab that are used for Energy sub-building max floor areas.
Other Performance Indicators
GRESB Field | Envizi Data Source |
|---|---|
Data Availability - From - (yyyy-mm-dd) | 1st of the Month from the earliest available data |
Data Availability - To - (yyyy-mm-dd) | Last day of the month from the latest available data |
Whole Building - - Consumption (m3) | All water consumption in the related building space, within the related data type category of ‘water’ |
Whole Building - - Floor Area Covered | If activity data exists, floor area coverage location setting, asset size (AC), tagged whole building floor area account |
Whole Building - - Maximum Floor Area | Special condition: If there is no data available for Water, then GRESB requires at least the maximum floor area field is populated. Therefore if no data available for Water, populate with asset size (AC), tagged floor area account. If activity data exists, asset size (AC), tagged floor area account. |
Base Building - Shared Services - Consumption (m3) | All water consumption in the related building space, within the related data type category of 'water |
Base Building - Shared Services - Floor Area Covered | If activity data exists, floor area coverage location setting, max coverage (assumes full coverage) |
Base Building - Shared Services - Maximum Floor Area | If activity data exists, floor area location setting (RC), if blank then tagged floor area account. |
