GH1: Outdoor & Parking
Assessment Instructions
Participants must report this metric at the asset level.
GRESB automatically populates this indicator in the assessment response once participants have aggregated asset-level data from the Asset Portal.
When using the Asset Spreadsheet to upload asset-level data, GRESB recommends reviewing the instructions below in conjunction with the corresponding spreadsheet tab. The Cell Code column in the Input section indicates where to report each metric in the spreadsheet.

Complete these fields if GHG emissions include Outdoor/Exterior Areas/Parking and are measured separately. Otherwise, the GHG emissions from outdoor/exterior areas/parking can be included in the Scope 1-3 Whole Building section(s).
Example
An office building has underground parking. If energy is sub-metered for the parking area, report the associated emissions values separately in the corresponding fields. If not, include the total outdoor emissions under the Whole Building section(s).
Note: This section should not be used for stand-alone parking assets (e.g., stand-alone multiple-story parking buildings). In those cases, select "Parking (indoors)" as the Property Type in the Asset Characteristics section.
Validation: What evidence is required?
This indicator is subject to automatic validation. No evidence is required. Refer to the page below for guidance on how to resolve automatic validation errors and warnings. Validation Basics
Scoring
Outdoor emissions contribute to the GH1 like-for-like performance improvement (2 points total) score.
If an asset's Scope 1+2 or Scope 3 spaces are eligible for like-for-like scoring, the corresponding outdoor consumption will contribute to the total like-for-like-eligible consumption of each space.
Frequently Asked Questions
How do I report GHG data coverage for an asset with varying levels of data coverage across multiple energy types?
You may assume that each energy type contributes equally to the total energy consumption. In such cases, the reported data coverage may be calculated as the average data availability across all relevant energy types.
Example 1:
An asset uses two energy types that fall under Scope 2:
Electricity with 100% data coverage
District Heating and Cooling with 0% data coverage.
Participants are allowed to assume equal contribution from each, i.e. that 50% of the energy consumed comes from each energy type i.e. dh&c and electricity, so that the resulting GHG Scope 2 data coverage equals 50%.
Example 2:
An asset uses three energy types that fall under Scope 3:
Electricity with 100% data coverage
District Heating & Cooling with 20% data coverage
Fuel with 50% data coverage
Participants are allowed to assume equal contribution from each. The Scope 3 data coverage would therefore be calculated as : (100% + 20% + 50%) / 3 = 57%
What data does GRESB explicitly require from participants to report in the GHG tab?
Participants are required to report emissions calculated with the Location-Based method. It is optional to report emissions calculated using the Market-Based approach though this will not be factored into the final score. Entities are responsible for determining the most appropriate emission factors to use when converting energy consumption into GHG emissions:
For Location-Based emissions, select the most relevant grid average emission factor for the specific geographic location of the asset.
For Market-Based emissions, select the most relevant market-based emission factor, taking into account the specific energy supply of the asset.
For further guidance, refer to the GHG Protocol.
