Focus on our expertise.

Avans Hogeschool
In 2024, Unica Building Projects started work on the construction of Campus 300, in ‘s-Hertogenbosch. The project comprises a modern teaching location for the Avans University of Applied Sciences and student flats for the Brabant Wonen housing corporation. This specialist campus project, due to be handed over in the autumn of 2025, is a joint project between ourselves and building contractors Van Wijnen.
Our teams are already hard at work on the electrical engineering systems. Sub-floor electrical outlet boxes have been installed on the first three floors, so that future teachers and students will have access to power throughout the building. We are also responsible for the 230V wiring, wall sockets, lighting and cable ducts. Campus 300 will be a functional, futureproof building with underground carpark and green outdoor space. We are proud to be able to contribute our expertise in creating a pleasant and sustainable learning environment.

Jeroen Bosch Hospital
Since 2015, Unica Building Services has been responsible for the maintenance of the electrical engineering systems at the Jeroen Bosch Hospital, and will continue to provide this service at least through to 2027. With a permanent team of service engineers, we perform preventive and corrective maintenance at four locations.
In 2024, we upgraded the hybrid operating theatre which included modernising various systems and implementing temporary measures. Together with sister companies EAL and Regel Partners, we also replaced the entire security system for the Jeroen Bosch Hospital. The new integrated system includes control rooms, video management and detection systems for fire, burglary and access control. This work will help ensure a safe and efficient hospital environment focused on innovation and reliability.

Delftse Poort
Delftse Poort, an iconic office building in Rotterdam, recently underwent major renovation work to ensure continued future proofness. Unica Fire Safety played a key role in replacing the fire alarm systems and optimising the sprinkler systems. This also involved upgrading the office complex with more efficient systems.
And the greatest challenge? Delftse Poort had to remain fully operational during the renovation. The building, with a staggering 106,000 m² of office space, is home to leading multinationals including Shell and Nationale Nederlanden. Thanks to close collaboration with sister companies, the renovation work will be carried out without disturbing the operation of the building. Smart phasing and temporary solutions will ensure fire safety, underlining the ability of our specialists when it comes to complex renovation projects. The entire building must be certified fire safe by the end of 2025.
WTC Amsterdam
WTC Amsterdam, a dynamic commercial complex housing more than 330 companies, now has a completely renovated security lodge thanks to the efforts of Unica Access & Security. We supervised and worked alongside a group of partners to seamlessly integrate a new secure and efficient access control system, built around the essential requirements of open standards and custom solutions.
The new security lodge is equipped with the very latest technologies in a combined system in which cameras, intercom, burglar detection and access control are seamlessly integrated. In addition to the technical upgrade, the renovation includes ergonomic workstations with sit-stand desks, large monitor screens, a videowall and an audiovisual solution that enables users to operate all systems from a single mouse and keyboard. The lighting has been optimised to prevent reflection and improve focus. The lodge is the control centre for the public areas, where security staff inform, register and check visitors to the WTC 24/7.

University of Leiden
In 2024, on behalf of the University of Leiden, Unica Building Intelligence replaced the climate and control system in the Sylvius building, which houses the Institute of Biology Leiden (IBL), a university institute responsible among others for research into plants and plant behaviour.
The institute uses climate cells in which students can determine the individual interior climate and control the lighting according to a variety of scenes and colour spectrums. Using data, this enables students to conduct research into the impact of specific scenes on plants. This of course requires a reliable climate control system. One remarkable feature of this particular system is the block to prevent the time change from standard time to daylight savings time, since the time shift can have a major impact on the research. After all, there is no such thing as daylight savings time in nature!

De Scheg Maastricht
In Maastricht, the social heating company Warmtelevering Wonen Limburg (WWL) has recently completed a new-build housing complex, De Scheg. Over the next 15 years, Unica Energy Solutions will be supporting WWL in the design, implementation and maintenance of its power generation plant.
The technical challenge for this project lies in the fact that the heat and cold must be extracted from the air combined with the fact that grid congestion results in restricted connection capacity. Although no power may be returned to the electricity grid, we have still succeeded in installing the largest energy roof in the Netherlands, with a capacity of 500 PVT panels. We have integrated innovative heat pumps in the design to allow excess heat to be stored in buffers. This is one of the first ever collective power generation plants using heat pumps that works with natural coolants; propane and isobutane.

Aqualab Zuid
In 2024, Unica ICT Solutions was selected by Aqualab Zuid as the perfect partner for optimising its field service process. The laboratory, based in the Biesbosch area of Brabant, helps ensure safe drinking water for the Netherlands. Staff carry out both routine and ad hoc surveys of water quality and test a variety of samples.
This makes planning for the field service a challenging task. To optimise the operation, the planning process had to be automated. Using Dynamics 365 Field Service and a custom built application, Unica ICT Solutions helped simplify the application landscape so that Aqualab Zuid is now able to optimise the deployment of its field service staff.

Delicia
Thanks to the efforts of Unica Industry Solutions, chocolate manufacturer Delicia was able to achieve an energy saving of more than 30%. For the manufacturer from Tilburg, ending the use of natural gas has been an ambition since 2018.
A series of studies revealed that phasing out gas by introducing an industrial heat pump was the best solution. Our engineers translated those studies into a technical system which was implemented in 2023. This more than sustainable solution means that residual heat and residual cooling form the start of the new process. Thanks to this system, the production lines and buildings at Delicia are always maintained at the required temperature.

Over a period of two years, Unica Datacenters has designed and built a twin datacenter for the Ministry of Defence. The two datacenters have a combined gross floor area of 6,000 m2 and each has an IT capacity of 2.5 MW. We were responsible for the site preparation work, the entire structural scope, the mechanical and electrical engineering systems and the white space layout.
Ministry of Defence
The datacenter has been to be built fully redundant, thereby massively reducing the risk of operational failure. It was designed with a solid focus on sustainability, including solar panels that generate 10% of the energy requirement. The primary system for cooling the IT system is based on free cooling using outdoor air. If additional cooling is required, adiabatic cooling is provided using groundwater from an on-site source. This technology contributes to efficient thermal discharge and massively reduces energy consumption.
