Covers all building types: offices, warehouses, factories, co-working spaces, data centres, and more

Supports both manual entry (single building form) and bulk imports (Excel or Google Sheets templates)

Automatically estimates missing data based on surface area, employee count, and country-specific benchmarks

Tracks data completeness per building with a progress indicator

Offers Location-based and Market-based emission views for Scope 2 reporting

Provides built-in quality controls to flag inconsistencies before finalizing your data

Proportional occupancy: If your company occupies only part of a building, report only your portion. For example, if a building is 20, 000 sqft and you occupy 10%, enter 2, 000 sqft and 10% of total energy consumption.

Remote workers: Employees working from home are handled in the Employee Survey module. Do not include their home offices here.

Co-working spaces: Enter the average surface area your team uses. Only count employees who actually work on-site when filling in the employee count for that building.

Prepare your data: check the templates for required fields and start gathering information

Invite your building manager: you can send an invitation directly from this screen to a colleague who manages your building data

Download templates: the building template and consumption template are available in both Excel and Google Sheets formats
You can also click "Watch demo" for a guided walkthrough of the module.
Once ready, click Continue to move to Data collection.

Country-Building surface area(indoor area only; if shared, enter only your team's portion)

Number of employees (on-site only — include full-time, part-time, hybrid, and interns; exclude fully remote employees)

Note: Surface area and number of employees are "at least one required" fields. You must fill in at least one of the two to allow emission estimation.

Building occupancy: Was the building occupied for the entire assessment year?

Yes (full year)

No(provide a move-in date and/or move-out date to cover only the relevant period) Additional building details-Construction year — used for building construction emission calculations

Full address / Building location-*City size*— used to identify the electricity grid

Parking — does the building have a parking area? If yes, enter the parking surface area

Air conditioning — is the building equipped with an AC system using refrigerant gas?

Heating — do you use heating in this building? If yes, select the heating type (Gas, Fuel, Heating network, or Electric)

Note: If you indicate that you use electricity,heating or air conditioning, you will need to provide a consumption figure—either using your own data, or by selecting “No, estimate my consumption” in the Consumption template.Operational control (advanced)
By default, the checkbox "My company has the operational control over this building" is checked. Keep it checked unless you are certain your organisation does not have operational control.
If you uncheck it, you must select a precise ownership type:

Our organisation rents and uses the building (lessee)

Our organisation owns and rents out the building (lessor)

Our organisation is investing in the building (investor)

Our organisation has financed the building (lender)

Note: Changing the operational control impact the scope of corresponding emissions. If you have the operational control of te building, the emissions will lend on scope 1 & 2. If you do not have the operational control, emissions will be in scope 3.
​Scope adjustments (advanced)
You can choose which emission sources to include in the calculation. By default, all are included:

Building waste

Building construction

Parking construction
Uncheck an item if it doesn't apply or is already covered elsewhere in your assessment.
**Entity information (optional) **
Used to match buildings with the corresponding company entity in your GHG inventory:

Entity name

Business unit

Analytic tags

Edit or Delete a single building (click the action menu on the row)

Bulk delete — select multiple buildings and delete them all at once. Note: all associated consumption data will also be deleted.

Filter by quality control — apply a filter to show only buildings flagging a specific quality control issue

Building: select the building this consumption belongs to

Consumption type: Electricity, Heating, or Air conditioning

Consumption name: auto-generated (e.g., "Electricity consumption 1"), feel free to edit

*Do you have the exact consumption value?*-Yes: enter value and unit (kWh, kg, m², etc.)

No, estimate my consumption: Greenly will estimate based on surface area, employee count, and country benchmarks

Which period does this data cover?-Full assessment year (based on your occupancy period)

Specific period: select a custom date range (e.g., monthly or quarterly data)
Note: When you are using estimations instead of exact value, the estimations will mandatorily cover the entire year.
Additional fields depending on consumption type:

Heating: select the heating type; if "Heating network" is selected, identify the connected network

Air conditioning: optionally select the refrigerant gas type (e.g., R410A) and provide either the gas reload amount or the air-conditioned surface area

If your building was not occupied for the full assessment year, the consumption period will automatically be adjusted to match your occupancy dates.

Edit or Delete a single consumption entry

Bulk edit: select multiple consumption entries and apply changes to all at once

Bulk delete: select multiple consumption entries and delete them together

Collection progress (%): based on the number of data points filled in. Each building can earn up to 3 data points: 1 for electricity, 1 for heating, 1 for air conditioning.

Completed buildings: Count of buildings with least some consumptions imported. Consumption can be set to 0 to complete the building if this type of consumption is not relevant for the build (eg. no AC on the building)
You can only complete the module if each importing building is completed.

Files: number of imported template files
You can also switch between the Location-based and Market-based view at the top of the screen.

Building name consistency — flags buildings whose names appear inconsistent across entries

Activity duplicate — detects consumption entries that may be duplicates

Surface area consistency — flags buildings whose surface area has changed significantly compared to previous years, which may signal a data entry error
For each control, you can:

Review the affected buildings in the filtered table

Go to building to edit the data directly

Dismiss warning(s) and provide a written justification if the change is intentional (e.g., a building expansion)

Location-based — emissions calculated using the average carbon intensity of the local electricity grid. This is the default "where you are" approach and ignores any special energy contracts.

Market-based — emissions calculated based on the specific electricity you purchased, accounting for Renewable Energy Certificates (RECs), Guarantees of Origin (GOs), and Power Purchase Agreements (PPAs). Only available if you are using the GHG Protocol methodology.
Emission results are displayed as interactive graphs (Luzmo) and broken down by:

Electricity (Scope 2)

Heating (Scope 1 or 2 depending on energy type)

Air conditioning (Scope 1)

Building construction, waste, and parking (Scope 3)
For more detail on Location-based vs Market-based, refer to:

Mark the task as Done-Lock your data to prevent accidental changes
You can still reopen the module at any time by clicking "Reopen module for editing". This will move the status back to In progress. Note: updating data after completion may delay report generation, as it can trigger additional quality controls.
After completing, you will be invited to rate your experience and share feedback to help improve the module.

Create a single entry and select the predominant building type (e.g., "Office" if most of the space is offices). This is simpler but slightly less precise.

Split the building into two separate entries — one per use type — and divide the surface area, employee count, and energy consumption proportionally. This provides more granular emission factors for building construction, though it does not affect energy consumption estimates.

Scope 1: Direct emissions from on-site energy use — gas boilers, fuel heating, refrigerant leaks from air conditioning systems.

Scope 2: Indirect emissions from purchased electricity or district heat used to power the building.
Greenly calculates these based on reported or estimated consumption and applies country- or region-specific emission factors from national databases (ADEME for France, DEFRA for the UK, EPA/eGRID for the USA, IEA or ElectricityMaps for other countries).

Location-based: Uses the average carbon intensity of the local power grid. It is the default approach and does not account for any green energy contracts.

Market-based: Uses the carbon intensity of the specific electricity you purchased. It accounts for Renewable Energy Certificates (RECs), Guarantees of Origin (GOs), and Power Purchase Agreements (PPAs). This view is only available if your organisation uses the GHG Protocol methodology.
See the dedicated article for more details: Location-based vs Market-based for Scope 2

Surface area: enter only the floor space your team occupies (not the total building area)

Energy consumption: enter only your share of the total energy consumption

Employee count: include only employees working on-site for your organisation
