RealEstateCore Consortium Introduces Lighting Domain Extension to Advance Smart Building Standardization

[Stockholm, Sweden – October 21, 2025]

The RealEstateCore (REC) consortium is proud to announce the release of a new domain-specific extension to the RealEstateCore ontology: Lighting. Developed in close collaboration with experts from Fagerhult Group (via its Organic Response platform) and Zumtobel Group (via its technology company Tridonic), this extension represents a significant step forward in the standardization and semantic modeling of lighting systems within the building environment.

Built on RealEstateCore’s deep integration with Brick Schema, the Lighting extension empowers building owners, operators, and solution providers with a shared, interoperable vocabulary for describing lighting systems, devices, and behaviors in real estate contexts.

The lighting extension has been developed and tested in the live environment at KTH Dig-IT Lab, an interdisciplinary collaborative competence center focused on reducing buildings’ environmental impact through digitalization. This real-world testbed platform has enabled the consortium to validate the extension’s functionality across diverse building systems and use cases.

This development accelerates the adoption of truly interoperable smart buildings, saving time and costs in integration projects.

Enabling Domain-Specific Semantics for Smarter Operations

Domain-specific extensions are now a key feature of the RealEstateCore ontology, designed to provide targeted, detailed models for specific areas of building systems such as HVAC, energy, access control, and now, lighting. By extending the core ontology with deeper semantics, RealEstateCore ensures that complex subsystems can be modeled, understood, and optimized within a unified digital ecosystem.

With the introduction of the Lighting domain, RealEstateCore delivers an extensible framework that mirrors real-world lighting infrastructure and supports dynamic interaction with IoT devices, control platforms, and data analytics tools.

“Lighting plays a pivotal role in occupant comfort, energy consumption, and overall building intelligence,” said Erik Wallin, chairman of the RealEstateCore Consortium. “This new extension is a practical response to industry demand, enabling property owners and operators to implement lighting solutions with standardized semantics that support integration, automation, and long-term maintainability.”

“At Fagerhult Group, we believe lighting is no longer just about illumination; it’s about intelligence, adaptability, and sustainability,” said Johan Lembre, CTO of Fagerhult Group. “By initiating and driving the RealEstateCore Lighting extension with Zumtobel Group, we’re enabling smart lighting to become an integrated part of the smart building, reflecting the realities of modern lighting. This collaboration supports our mission to deliver future-ready solutions that improve energy efficiency, user comfort, and building intelligence.”

Interoperability, Efficiency, and Insight

The new Lighting domain provides concrete benefits to end users across the real estate and smart building value chain. Property owners and facility managers can now:

  • Integrate lighting systems from different vendors under a standard semantic model.
  • Enhance operational efficiency through improved asset monitoring and control.
  • Accelerate maintenance and troubleshooting by enabling context-rich data for every lighting asset.
  • Drive sustainability goals by supporting advanced energy-saving strategies and daylight-responsive lighting.

Because the extension is built on RealEstateCore’s alignment with Brick Schema and other open standards, it promotes vendor-neutral integration and ensures compatibility with global proptech ecosystems.

A Collaborative Effort Rooted in Industry Expertise

The development of the Lighting extension reflects close collaboration between RealEstateCore and two global leaders in smart lighting: Fagerhult Group (via Organic Response) and Tridonic. Their deep domain expertise ensured that the new ontology components are grounded in the realities of modern lighting systems, covering key elements such as luminaires, sensors, drivers, control groups, occupancy behavior, and more.

By bridging cutting-edge ontology engineering with practical lighting solutions, the Lighting extension supports the evolution of real estate into smarter, more connected, and more sustainable environments.

The Lighting domain is now publicly available as part of the open-source RealEstateCore ontology.
