Real estate data in Flanders was fragmented across multiple agencies, making it hard to access and manage.
We applied an agile development process combining Scrum and Kanban for a flexible, collaborative build.
We built the Gebouwenpas. A scalable, modular digital platform that centralises all real estate information using Liferay DXP, Spring Boot, and Angular.
A user-friendly, award-winning platform that provides comprehensive, accessible property data for both citizens and government stakeholders.

The information was scattered across different agencies and authorities. This made it difficult to quickly find the documents you need. It was up to us to bring all that data together and make it easy for owners, estate agents, notaries and policymakers to find their way.
We have developed a digital platform that brings all that fragmented information together. One digital passport that contains all important data. First for residential buildings only: the Woningpas. In a next step, for all other types of buildings, such as offices and business premises: the Gebouwenpas.
We opted for Liferay DXP as the foundation of the platform. As a Liferay Gold Partner in Belgium, VEKA can be sure we get the most out of the platform for them. Thanks to us, they are now on the front row for new, interesting functionalities.
On top of Liferay DXP, we have added specific functionalities with Spring Boot and Angular. The result is a modular and scalable solution.

Key functionalities:
Overview of all certificates and reports linked to a building
Integration with data sources of the Flemish government
Single Sign-on (SSO) for seamless access
Intuitive dashboards and widgets for users
Strict security with JSON Web Tokens (JWT)
Thanks to feature flags, we can roll out new functions smoothly. Without making the platform temporarily inaccessible.

Together with the government, we continue to further develop the platform. An overview of some of the most important optimisations and new features:

To work flexibly and efficiently, we used an agile methodology with a combination of Scrum and Kanban:
Sprints of 3 weeks with interim demos.
User stories to serve customised content.
Continuous feedback loops and adaptability during development.
Transparent monitoring via JIRA and dashboards.
The agile methodology is very dynamic, structured and comprehensible. Thanks to the dashboards in the planning software Jira, we know perfectly how far along our project is and whether everything is going according to plan.

A better overview for citizens and government bodies.
A platform that is future ready: thanks to feature flags, we can roll out new functionalities quickly and efficiently. Without affecting users or rendering the platform inaccessible.
Comprehensible data: we transform the raw numbers into relevant insights about the building.
Our work was awarded the Henry van de Velde Design Award 2020 in the Digital Product category. These awards honour
Companies and governments that use design intelligently.
Products, services and systems with a positive impact on society, the environment and the economy.

A tremor in the Force. The last time I felt it was in the presence of my old master. Don't act so surprised, Your Highness. A tremor in the Force. A tremor in the Force. A tremor in the Force.
Renson, a manufacturer in the outdoor living and climate control sector, needed a centralized solution to manage patio covers, shading, lighting, heating, and air quality systems across diverse hardware and networks. ACA Group developed integrated control applications that ensured reliable connectivity and unified system management. During COVID-19, a CO₂ monitoring feature was delivered within two weeks, resulting in faster product innovation and improved indoor and outdoor environmental control.


Stad Hasselt, a local government organization in the public sector, wanted to improve digital access to municipal services through a mobile application but faced low usability and user adoption. ACA Group conducted UX audits and real-world user testing to optimize the app’s design and functionality. This resulted in a user-friendly mobile app with higher user satisfaction and improved accessibility to city services for residents.


Attentia, a provider in the HR and wellbeing services sector, needed to improve its customer journey and online presence but faced challenges with fragmented digital platforms. ACA Group developed a unified, future-proof website by consolidating multiple systems into one platform. This integrated web solution enhances the #OneAttentia experience, enabling customers to easily access services while improving operational efficiency, brand consistency, and digital engagement.


Duvel Moortgat, a brewery in the food and beverage industry, needed a reliable way to detect damaged pallets to ensure safe and efficient beer transport. ACA Group implemented an AI-powered computer vision solution that automatically identifies pallet defects during logistics processes. This automated quality control system reduces manual inspection, lowers operational costs, and improves supply chain efficiency and product quality.


Aqtor!, a provider of orthopedic and mobility aids in the healthcare sector, faced inefficiencies in appointment management that impacted operational productivity and patient experience. ACA Group implemented Planit, a digital planning and scheduling system, to streamline appointment workflows and optimize resource allocation. This solution reduces administrative workload, improves care quality, and increases customer satisfaction by enabling faster, more efficient patient service.


MobilityPlus, a provider in the electric vehicle (EV) charging and sustainable mobility sector, needed to evolve from a standalone mobile app to a scalable digital platform but lacked a unified data and application architecture. ACA Group built an integrated digital ecosystem with a mobile app, web portal, Azure data platform, and AI-driven solutions. This enables data-driven operations, improves scalability, and supports business growth while strengthening MobilityPlus’ market position.
