One dataspace for every participant in the chain.

What is your role in the chain?

Control over portfolio data without new lock-in.

For institutional owners and owner-occupiers, building data sits scattered across BMS portals, FM providers, meters, tenants and reporting chains. buildinglinks makes that data usable in a controlled way for ESG, maintenance, comfort and optimisation without the owner losing control.

Today

01 Manual consolidation from dozens of portals and exports.
02 No portfolio-wide comparison without normalising measurement points, units and floor area.
03 CSRD, GRESB and EU Taxonomy substantiation demands auditable data series, not loose spreadsheets.

With buildinglinks

01 Automated data collection for ESG and CSRD reporting.
02 Portfolio-wide energy benchmarking with validated metering data.
03 Green lease monitoring with revocable tenant authorisation.

Set up once, serve multiple owners.

Property managers and FM providers sit between owner, tenant and supplier. They have to deliver the same kind of data over and over in different formats, deadlines and portals. buildinglinks makes management on behalf of the entitled party explicit and revocable.

Today

01 One manager, dozens of owners and just as many export formats.
02 Service charges, maintenance and energy are traced manually from different systems.
03 When management changes hands, history, context and access rights vanish into export projects.

With buildinglinks

01 A standardised connector between manager and multiple owners.
02 Delegated, purpose-bound access on behalf of the owner.
03 An auditable CSRD and ISAE 3402 data flow from the same source.

Data from leased buildings, with verifiable provenance.

Corporate tenants have climate targets, comfort requirements and CSRD obligations, but the metering data often sits with the landlord, property manager or BMS vendor. buildinglinks makes data access from leased buildings technically feasible and auditable.

Today

01 Scope 3 data from leased buildings arrives late, manually and in varying formats.
02 Service charges are hard to verify without the underlying consumption series.
03 Comfort complaints stay subjective while temperature, CO₂ and air-quality data sits in the landlord's BMS.

With buildinglinks

01 Automated Scope 3 data collection from leased buildings.
02 Making green lease arrangements technically enforceable via authorisation, delegation and purpose binding.
03 Linking comfort monitoring to lease and SLA arrangements.

Faster access to reliable building data for optimisation and performance evidence.

EMS vendors, analytics platforms and ESCos deliver value on top of data, but lose time on BMS integrations, point mapping and unclear authority. buildinglinks makes access repeatable under the conditions of the entitled party.

Today

01 Every new customer is another integration project with different protocols and point names.
02 Unclear data ownership blocks onboarding: who is allowed to grant access?
03 Data quality, units, time zones and metadata have to be cleaned up per building.

With buildinglinks

01 A standardised BMS data connection with semantic point mapping.
02 A formal data request on behalf of the building owner via trust and delegation.
03 Publishing derived optimisation, M&V and flexibility signals as your own data service.

Delivering data as a repeatable service instead of project-specific exports.

Installers, FM providers and BMS vendors hold the operational data that owners and service providers need. buildinglinks makes delivery, handover and evidencing repeatable without every request becoming a new export project.

Today

01 Point-mapping and commissioning knowledge lives in heads, project files and proprietary systems.
02 SLA, maintenance and fault evidence is reconstructed after the fact from CAFM, CMMS and BMS.
03 Data Act and BACS questions lead to ad-hoc exports and legal uncertainty without a standard route.

With buildinglinks

01 Handing over commissioning, as-built and point-mapping data via a connector.
02 Making maintenance logs and work orders available to owner and FM.
03 Auditable SLA and BACS evidencing with a transaction log.

Decentralised dataspace

Buildinglinks coordinates trust and agreements. The data stays at the source.

Connectors exchange metadata, digital evidence and contract agreements via the control plane. The actual building data only flows afterwards via the data plane: directly between consumer and provider, or via a route controlled by the entitled party.

Every participant runs a connector. buildinglinks supplies one: buildingconnector — open source, managed or self-hosted. Or any conformant connector.

Buildinglinks unlocks data but never stores it.

Interoperability: data standards and mapping

Every participant maps once. From then on all connectors speak the same language.

Translation happens in the connector, via a mapper plug-in. A data provider maps its own model once to the canonical model — SAREF + Brick — and a data consumer maps once back to its own model. In between, all connectors speak canonical only. For common systems buildinglinks supplies ready-made mappers.

Why now

European legislation makes controlled sharing of building data no longer optional.

Building data will soon have to be generated, made accessible and accounted for by law — and the owner gains the right to share it. The law prescribes that it happens, not how it happens securely and demonstrably between parties. That gap is what buildinglinks fills.

Data Act

A right to your own installation data.

The user of connected building installations is entitled to the data generated by their use and may have it shared with a third party of their choice. That touches BMS, EMS, meters and other smart installations as soon as they generate data as a connected product or related service.

Regulation (EU) 2023/2854 · applicable since Sept 2025

EPBD · BACS

Building automation becomes mandatory.

Utility buildings above 290 kW must have a building automation and control system; from the end of 2029 the threshold drops to 70 kW. The installed base is being made data-generating by law — but that data is stuck in closed systems.

Directive (EU) 2024/1275 · Dutch Bbl, from 1 Jan 2026

EPBD · building data

Building information goes digital.

The EPBD pushes towards digital energy performance certificates, national building performance databases, renovation passports and data exchange. Building data must not only exist, but also become findable, explainable and shareable.

Directive (EU) 2024/1275 · transposition by 29 May 2026

CSRD · ESRS E1

Accountability per building, chain-wide.

Large and listed companies report under ESRS on climate, energy use and emissions in their own operations and value chain. For real estate that means substantiation per building and traceable data from management, meters and installations.

CSRD / ESRS E1 · Directive (EU) 2022/2464 + Regulation (EU) 2023/2772

And the solution is in the law as well

The Data Governance Act explicitly provides for the neutral data intermediary.

The same European legislation regulates the neutral intermediary that facilitates data sharing between provider and consumer without using the data itself — independent of both, as part of a Common European Data Space. That is exactly what buildinglinks is.
