A new app to showcase each local authority’s built heritage

To complement Building360, its property management application, LSC360 is developing the BEN platform, which will be unveiled at the upcoming World Smart City Congress in Barcelona this November. An acronym for Building Embedded Network, this IoT (Internet of Things) and artificial intelligence solution aggregates energy consumption data from local authority buildings in real time to detect anomalies,
issue alerts and make recommendations for optimisation.

Luxembourg’s local authorities, like all public bodies, manage a substantial built environment. What challenges do they face today?

Sarah Weidert: Luxembourg’s local authorities have a significant property portfolio, with numerous buildings to manage. Today, one of the main challenges relates to managing the information concerning these buildings. The data generally exists, but it is often scattered across different departments, stakeholders or storage media. The idea is therefore to centralise all this information in one place to make it easier to access. This would enable essential documents such as plans, planning permission or energy performance certificates to be found quickly, whilst providing a comprehensive and more efficient overview of the municipality’s entire property portfolio.

In what context was this platform conceived?

Saël Gramdi: This platform forms part of the framework of new regulatory obligations. Circular 2025-035 on the transposition of EU Directive 2023/1791 of 13 September 2023 on energy efficiency requires public bodies to reduce energy consumption by 1.9 per cent per year and to renovate 3 per cent of their energy reference area each year. Without a suitable tool to centralise data and monitor indicators, these obligations become unmanageable for teams already juggling numerous tasks. Until now, there has been no solution designed specifically for the Luxembourg context, incorporating both the geographical dimension and local regulatory obligations: ministerial authorisations (ITM, the Environment Administration and the Water Management Administration), Climate Pact, Klimabonus, Lëtz Prepare… It is precisely this gap that our Building360 app fills.
To complement Building360, we are developing the BEN (Building Embedded Network) platform, in partnership with MABU Concepts – a finalist at the 2025 World Smart City Awards in Barcelona – which brings expertise in IoT and artificial intelligence.

What is LSC360’s role in the development of this solution?

SG: LSC360 is the driving force behind the project and is responsible for its overall management. Our position is unique in Luxembourg, and this is what gives this solution its strength: we are both a recognised player in geographic information systems, present in around two-thirds of local authorities via SIGcom, and a leader in environmental and energy expertise, as one of Luxembourg’s largest engineering consultancies in these fields. This dual expertise – GIS and energy and the environment – lies at the heart of LSC360’s DNA and is a valuable asset that enables us to offer a comprehensive solution.
In practical terms, we are developing a specific application integrated into SIGcom which we call the Building360 App – our municipal asset management platform – which communicates with BEN, the Building Embedded Network.
LSC360 handles GIS integration, knowledge of the municipal area and deployment; MABU Concepts provides the sensor and predictive layer.

Together, Building360 and BEN form the two pillars of a single vision: to turn every building into a living digital twin – a building that can be monitored, understood and controlled in real time. Before eventually extending this approach to the entire municipal area.
And this is not a theoretical research project: LSC360 was selected as the sole project in the Energy category during the first round of the Ministry of the Economy’s Smart City call for projects. This is concrete validation
by the public authorities of the relevance of our approach.
Our participation in the World Smart City Expo 2026 in Barcelona forms part of Luxembourg’s representation at this global event, in coordination with the Luxembourg authorities.

What does the Building360 App offer that is new? What do public bodies stand to gain from it?

SW: The fundamental difference compared with existing tools can be summed up in one word: integration. The solutions available on the market – whether facility management tools or sector-specific energy platforms – are either too general to adapt to the Luxembourg regulatory framework, or focused on a single area without covering the other aspects of asset management.
Building360 offers five business modules within a single interface: Energy, Accessibility (for people with reduced mobility), Maintenance, Authorisation and Security. And because it is native to SIGcom, each building is geolocated, can be viewed on a map and is linked to local authority data. But we go even further: our services include 3D scans of buildings, allowing users to move virtually around the interior of each building from their workstation, as if they were physically there. The entire built environment becomes accessible, viewable and manageable from a single screen.
And if an organisation already has a BIM model, we can integrate it directly into SIGcom, with no loss of data and no need for double entry. As for buildings that do not yet have one, our 3D point cloud scan
enables us to measure the entire building to centimetre accuracy and generate a BIM model directly from this point cloud. LSC360 therefore offers a complete continuum: from the physical capture of the building to its intelligent, connected digital twin.

SG: It is this combination of GIS, 3D scanning, IoT and AI that constitutes the building’s true digital twin: Building360 provides the geographical and documentary framework, the 3D scan gives it a physical, navigable body,
and BEN breathes real-time intelligence into it. It is this geographical layer that lays the foundations for the building’s digital twin: every piece of equipment, every consumption figure, every regulatory deadline
is linked to a real, localised, living object. It is then BEN that brings this digital twin to life by feeding it real-time IoT data and applying artificial intelligence to move from simple observation to action.
For a public sector organisation, this translates in practical terms into a profound transformation in the way it manages its assets: it moves from reactive management – intervening only once a problem has already arisen – to proactive management,
thanks to the automatic detection of anomalies. IoT sensors constantly monitor energy consumption, temperatures and equipment, and issue alerts as soon as abnormal behaviour is detected,
well before it turns into a breakdown or additional costs. This is one of the fundamental differences compared with the passive reporting tools available on the market, which lack predictive alert capabilities.
Added to this is a feature we consider to be one of the most tangible benefits: a personalised energy adviser, powered by AI. By analysing all of a building’s data—
historical consumption figures, sensor data, technical specifications and occupancy levels—artificial intelligence is able to formulate bespoke optimisation recommendations: which equipment should be prioritised?
Which time slots should be adjusted? Which renovation works will deliver the best return on investment? It is no longer just a dashboard to consult; it is an assistant that suggests, alerts and guides.
At the building level, the digital twin is therefore already a reality, providing a comprehensive, dynamic and intelligent representation of every building. But this is only the first step towards a much broader ambition.

How is the Building360 App set to evolve?

SW: We designed the Building360 App with a modular and scalable architecture, so as not to lock users into a static solution. In the short term, the focus is on consolidating the five modules and rolling them out to pilot local authorities. In the medium term, two major areas of innovation are currently under development: an AI module for the automatic recognition of facilities in 3D scans, and a document analysis engine based on an LLM (Large Language Model) specialising in Luxembourgish regulations, to automate the extraction of information from technical reports and planning permission documents.

SG: But our long-term vision is even more ambitious. What we want to build is a sort of real-life SimCity, to use the video game metaphor that everyone is familiar with. Imagine an interface
where you can visualise an entire municipality in real time: its buildings, its energy consumption, its traffic flows, its environmental data – all superimposed on a living Geo Digital Twin of the area. What we’re
building, building by building, with Building360 and BEN, we want to assemble on a regional scale: a living municipal Geo Digital Twin, where data from every building is integrated into an overall view of the municipality. And above all, the ability to simulate: if we redevelop this neighbourhood, if we renovate these buildings, if we modify this infrastructure, what will be the impacts on residents, on energy consumption and on mobility? That is the promise of the digital twin at the local authority level, and that is what we are working towards.
