Purpose of this article
The Certifications module captures all building labels, ratings, awards, and renewable energy contracts associated with your assets — energy performance certificates, operational certifications, design and construction awards, and the procurement instruments used in market-based emissions accounting.
This article covers how to view certifications at the portfolio level, how to add or edit certifications on a specific asset, and how each field on the Certifications form is used.
Where to find Certifications
Certifications live in two places in the Data Collection Portal:
Portfolio level — overview across all assets:
Data Collection Portal → Portfolio → Certifications
This view shows a matrix of every asset and its certification status across each category — Active (with a count of active certifications) or Missing — plus the nearest expiry date across the portfolio. Use this view to quickly identify assets without certifications or with expiring certifications.

Asset level — detailed editing:
Data Collection Portal → Asset → Certifications
This is where you add, edit, or remove individual certifications on a single asset.
Certification categories
The Certifications module is organized into four tabs, each covering a different type of building certification:
Energy Rating— Energy performance certificates and labels. Examples: EU EPC, Energy Star, BBC, NABERS Energy.
Operational— Certifications based on the asset's actual operational performance. Examples: BREEAM In-Use, LEED O+M, NABERS Water/Waste/Indoor Environment, WELL Existing Building.
Design and/or Construction— Certifications obtained at the design or construction stage. Examples: BREEAM New Construction, LEED BD+C, DGNB, Passivhaus.
Renewable energy contracts— Renewable energy procurement instruments (PPAs, RECs, GOs, EACs) used for market-based scope 2 emissions accounting and GRESB reporting. This tab has a different structure from the other three — see the dedicated section below.
Note: The full list of supported certification types is aligned with GRESB's accepted scheme list. If a scheme you need isn't available, contact your Scaler account manager.
Adding a certification
To add a new certification on an asset:
- Navigate to Data Collection Portal → Asset → Certifications
- Select the relevant tab —
Energy Rating,Operational, orDesign and/or Construction
- Click Create new in the Certifications section
- Fill in the fields — see Field reference below
- Upload supporting evidence (the certificate file or PDF)
- Click Save
The certification appears in the table on the relevant tab and contributes to the asset's certification status at the portfolio level.

Field reference
The fields on the Certifications form, grouped by purpose.
Required fields
Group— Top-level category (Energy Rating,Operational,Design and/or Construction). Pre-filled based on the tab you're on.
Type— The specific certification scheme (e.g.EU EPC,BREEAM/In Use,Energy Star). Selecting a Group filters the available Types.
Level— The rating or grade achieved. Format depends on the Type — letter grades (A,B+,C), descriptive levels (Excellent,Outstanding), or pass/fail (Certified,Obtained). Always required, even for pass/fail certifications.
Date obtained— The date the certification was awarded. Required whenObtainment statusisObtainedor left blank.
Common fields
Score/index — The numerical score behind the rating, where the scheme provides one. Examples: an EU EPC kWh/m²/yr value, a BREEAM percentage score, an Energy Star score from 1–100. Optional for most certifications.
Note: For assets located in the United States or Canada, the Energy Star Score/index auto-populates from the latest ESPM 12-month period after you connect the asset to ENERGY STAR Portfolio Manager. Date obtained is set to the start date of that 12-month period (a tooltip on the field explains this convention).
Covered area + Unit — The floor area covered by the certification. Leave blank to auto-link the certification to the asset's full GFA. Only enter a value when the certification covers a sub-area (e.g. a single floor or wing). The unit (m² or ft²) follows the asset's unit system.
Obtainment status — The current state of the certification:
Obtained— the certification has been awarded.
Planning to obtain— the asset is registered for certification but not yet rated. LeaveDate obtainedblank in this case. Don't enter a registration or target date inDate obtained.
Expiration date — The date the certification expires. Used in the portfolio-level Nearest Expiry column.
Comment — Free-text notes about the certification.
Evidence — The certificate file or supporting documentation. Upload as PDF or image.
EU Taxonomy / SFDR fields
Used only when reporting against EU Taxonomy or SFDR. Leave blank if not applicable.
Primary energy demand— Primary energy demand of the asset in kWh/m²/yr.
Primary energy demand meets NZEB criteria— Yes/No against the country's Nearly Zero Energy Building threshold.
Percentage lower than NZEB criteria— How far below the NZEB threshold the asset performs, as a percentage.
Top percentage of the national stock in terms of PED— Whether the asset is in the top X% of national building stock for primary energy demand.
Note: NZEB thresholds are country-specific. Source the relevant threshold from the national energy regulation authority before completing these fields.
Legacy field — ignore
Date evidence submitted for review — A legacy field from a one-off GRESB scoring change. No longer used. Leave blank.
Renewable energy contracts (GRESB scoring only)
The Renewable energy contracts tab tracks the renewable energy procurement instruments (PPAs, RECs, GOs, Energy Attribute Certificates) used in market-based scope 2 emissions accounting. This tab is only relevant if you are reporting to GRESB — these contracts do not feed the certification status indicators in the portfolio Certifications overview.
The Renewable Energy Contract record does not classify your energy as renewable in Scaler — it only populates the matching columns in the GRESB Asset Spreadsheet export. Whether off-site electricity is treated as renewable in the export is driven by the Percentage green and Source fields on the meter itself, not by this record. The absence of a Renewable Energy Contract record does not remove the renewable classification from the energy consumption figures.
The Renewable Energy Contract record captures the GRESB-required attributes — Procurement type, Market-based claim, Proximity, and Vintage of generation — that populate the matching columns in the GRESB Asset Spreadsheet. All four fields must be populated for GRESB to award market-based claim and procurement quality points.
If a field is genuinely unknown, selecting Unknown clears the blocking alert in Scaler. This avoids the missing-data alert but may negatively impact your GRESB score, since valid procurement attributes are required to earn those points. Where possible, populate the actual values rather than relying on Unknown.
The form structure differs from the other three tabs:
Name— An internal identifier for the contract (e.g. "REC Contract — Energy Provider X").
Procurement type— The procurement instrument used for this contract. Options follow GRESB 2026 categories:Self-generation from facilities owned by the company,PPA (Power Purchase Agreement),Project-specific supply contract with electricity supplier,Retail supply contract with electricity supplier,Default delivered renewable electricity from the grid,Australian-Accredited GreenPower,RE100 Passive Procurement type 5.2, andMixed. UseAustralian-Accredited GreenPowerfor Australian assets sourcing electricity through the GreenPower program, including those reporting via NABERS Energy.
Market-based claim—Bundled(energy + attributes together) orUnbundled(attributes only).
Proximity— Geographic relationship between generator and asset:Same market,Different market, etc.
Vintage of generation— Reporting-year alignment of the certificates:Performance year,Prior year, etc.
Start date— Required.
End date— Optional.
Purchased amount+Unit— Volume covered (e.g. MWh). WhenPurchased amountis populated,Unitbecomes required.
Evidence— The contract or certificate file.

Asset level vs building unit level
Certifications can be entered at both the asset level and the building unit level, but they behave differently.
- Asset-level certifications appear in portfolio-level analytics, dashboards, and report exports (GRESB, GRI, etc.). This is the right level for almost all certifications, even those that only cover part of a building — set
Covered areato the partial area instead of moving the entry to a unit.
- Building-unit-level certifications are for internal tenant relationship tracking only. They do not appear in portfolio-level analytics, dashboards, or report exports.
For details on building unit setup, see Building units: Setting up & entering data.
Editing or removing a certification
Click the pencil icon on any row in the Certifications table to edit. To remove a certification, open the row and use the delete option in the edit drawer. Removed certifications no longer count toward the asset's certification status.
Troubleshooting & common mistakes
Type dropdown shows no options → Select a Group first. The available Type values are filtered by the Group you choose.
Pasted Level value fails validation → Always pick from the dropdown rather than typing or pasting. Even visually identical text can fail validation. Re-pick Group → Type → Level in that order.
Energy Star score not appearing for a US/Canada asset → Confirm the ENERGY STAR Portfolio Manager integration is active for that asset. See ENERGY STAR connection set-up. ESPM sync runs monthly, so a new score may take up to 30 days to appear after the integration goes live.
In-progress certification won't save → Set Obtainment status to Planning to obtain and leave Date obtained blank. Don't enter a registration or target date.
Certification missing from portfolio reports → Check whether it was entered at the building unit level. Building-unit certifications are excluded from portfolio analytics — move them to the asset level if they should appear in reports.
