What changed in PropTech interoperability over the last 45 days?

From mid-November to late December 2025, platforms including Yardi, MRI Software, and Siemens rolled out open API and connector updates aligned to BACnet and Brick Schema. Standards bodies highlighted expanded Matter capabilities for commercial devices, bringing greater cross-vendor compatibility. Analysts from IDC and Gartner reported estimated 15–25% faster integrations in Q4 pilots as portfolios leveraged semantic models and event-driven APIs, reducing custom work and data harmonization overhead.

How does the EU Data Act affect building data access and interoperability?

The European Commission’s December guidance emphasized obligations for IoT data access and portability, pushing vendors to provide standardized interfaces and fair data-sharing paths. For PropTech, landlords and operators must be able to export and transfer building system data across providers without lock-in. This is accelerating the adoption of open APIs, common taxonomies, and audit-ready governance. Enterprises are prioritizing consistent payloads and semantic alignment to satisfy compliance and multi-vendor operations.

Which standards are driving practical cross-vendor integrations?

Matter, BACnet, and Brick Schema are central right now. Matter improves device-level compatibility for access, lighting, and energy systems. BACnet remains the backbone for building automation, while Brick Schema adds consistent semantic modeling to cut mapping errors. IFC alignment from design platforms like Autodesk helps bridge the gap between construction handover and operations, enabling smoother data handoffs into IWMS and analytics stacks without bespoke transformations.

What benefits are enterprises seeing from open APIs and shared ontologies?

Enterprises report estimated 10–20% cost reductions in data integration and 15–25% faster time-to-insight during Q4 pilots when using standards-aligned connectors. Harmonized equipment identities and event payloads reduce custom middleware demands and unlock multi-building analytics. Operators can more easily correlate occupancy, air quality, and energy signals for ESG reporting and optimization, with vendors like VergeSense and Density citing improved reliability in cross-portfolio analytics.

What should CIOs and COOs prioritize for 2026 building interoperability?

Prioritize event-driven APIs with clear versioning, device identity governance, and Brick/BACnet semantic alignment. Mandate Matter-compatible endpoints where feasible, and ensure IFC-based data exports from design/twin platforms for clean handovers to operations. Build a vendor-neutral data layer and establish portability policies aligned to the EU Data Act. Pilot with measurable KPIs—integration time, data quality scores, and analytics readiness—to quantify ROI and standardize successful patterns across portfolios.

PropTech Interoperability Ramps Up as Yardi, MRI, Siemens Ship Open APIs Under EU Data Act

PropTech vendors push new open APIs and standards-based connectors to unify building data, as the EU Data Act’s interoperability provisions start to bite. Yardi, MRI Software, and Siemens lead a December wave of releases aligning with Matter, BACnet, and Brick Schema, promising faster integrations and lower costs for landlords and operators.

PropTech Interoperability Ramps Up as Yardi, MRI, Siemens Ship Open APIs Under EU Data Act

Executive Summary

Major PropTech platforms including Yardi, MRI Software, and Siemens rolled out open API upgrades and standards-aligned connectors in late November–December 2025.
Standards bodies advanced interoperability with fresh updates around Matter, BACnet, and Brick Schema, improving cross-vendor device and data compatibility according to the Connectivity Standards Alliance and Brick Schema maintainers.
Regulatory momentum increased as the European Commission highlighted Data Act obligations for IoT data portability and access in December, accelerating enterprise adoption of open data interfaces per Commission guidance.
Analysts indicate enterprises integrating multi-vendor building systems saw estimated 15–25% reductions in integration timelines and 10–20% lower data harmonization costs in Q4 2025 IDC research, Gartner briefings.

Interoperability Moves: APIs, Connectors, and Shared Data Models

In December, property operations platforms accelerated their shift to open, standards-based integrations. Yardi announced new API endpoints and connector updates that map equipment telemetry to Brick Schema building ontologies, enabling faster normalization across mixed portfolios. Company materials emphasize broader support for BACnet device discovery and streamlined partner onboarding to its marketplace, aimed at reducing custom integration work and speeding deployment cycles Yardi newsroom.

MRI Software expanded its "MRI Connect" ecosystem with December enhancements to event-driven webhooks, single-tenant data isolation patterns, and a standardized equipment taxonomy for HVAC and occupancy sensors. The company says its updates align with Brick and BACnet naming conventions to reduce cross-system mislabeling, a common pain point in mixed vendor stacks MRI press. Meanwhile, Siemens pushed an update to its Building X open interface, citing deeper BACnet interoperability and a data model export built to simplify digital twin alignment and downstream analytics across CMMS and IWMS platforms Siemens press office.
