The Top 5 projects of Marquis Intelligence in 2025

The Top 5 projects of Marquis Intelligence in 2025 reflect a year marked by extensive experience and technical diversity.
As can be seen, the past year was defined by a wide range of projects. There were projects ranging from luxury hospitality and prestigious corporate facilities to critical aviation infrastructure to technically demanding yet smaller-scale implementations.

“Complex technical challenges are not obstacles, but incentives for precise engineering problem-solving in real-world conditions.” – Vladimir Janaćković, CEO, Marquis Intelligence

Selection Criteria

The selection of the Top 5 projects of Marquis Intelligence in 2025 was based on multiple factors. Consistent with previous years, the following criteria were taken into account:

• Technical complexity of the solution
• Degree of system integration
• Environmental sensitivity
• Continuity of cooperation
• Long-term operational reliability

Top 5 Projects of Marquis Intelligence in 2025

Based on the above criteria, the following projects were selected:

1. Mövenpick Teuta Kotor Bay, Risan, Montenegro

Marquis Intelligence implemented an upgraded PHOENIX solution for kitchen exhaust air extraction and purification within a UNESCO-protected zone.
As part of a globally recognized eco-conscious hotel brand, the project required strict environmental standards. Therefore, the system ensures efficient removal of grease, particles, and odors before exhaust air leaves the building.

2. Microsoft, Ušće Tower 2, New Belgrade, Serbia

Marquis Intelligence completed a new phase of indoor air purification system installation.
The team integrated bipolar ionization into the HVAC system and connected it to an automatic control loop with sensor-based regulation. This phase supports the continued expansion of Microsoft’s workspace.

3. Hilton Hotel, Belgrade, Serbia

Marquis Intelligence extended its seven-year collaboration on indoor air quality with Hilton Belgrade.
In 2025, the team upgraded the IAQ system in the hotel’s staff dining area, maintaining consistent air quality standards across the property.

4. London City Airport, London, UK

Marquis Intelligence delivered and installed replacement air purification units in the digital air traffic control tower.
In addition, the team performed structured system maintenance to ensure operational stability and reliability.

5. Kafeterija, New Belgrade, Serbia

Marquis Intelligence implemented a complex, multi-layered engineering solution to improve air quality in a café where smoking is permitted.
The solution combines advanced purification technologies with continuous monitoring to effectively address tobacco smoke.

Other Active Projects in 2025

Throughout 2025, Marquis Intelligence also executed several smaller-scale yet technically significant projects.

Notably, projects in approximately 10 residential apartments were completed under a turnkey model, including the delivery, installation, and commissioning of ventilation systems with high-efficiency heat-recovery units and integrated air-purification systems.
Projects were also implemented in commercial facilities, including CISCO offices in Belgrade, as well as gym facilities in private homes and corporate buildings.

Some of these projects have been presented through detailed case studies.

Projects Are Not Only About New Installations

Although project lists most often highlight new installations and retrofit solutions, it would be incorrect to overlook the maintenance segment.

Without regular and professionally conducted maintenance, technical systems gradually lose efficiency, stability, and reliability. Service activities are not an add-on, but a prerequisite for safe and long-term system operation.

In addition to the Top 5 projects in 2025, the maintenance segment included facilities such as the Emergency Center of Vojvodina in Novi Sad, Radio Television of Serbia in Belgrade, the Skyline business tower, and numerous other commercial and public facilities.

Maintenance confirms continuity of cooperation and long-term responsibility toward installed systems.

Conclusion

The Top 5 projects of Marquis Intelligence in 2025 demonstrate that air purification is no longer an optional upgrade, but an integral component of modern building technical infrastructure.
From luxury hotels and corporate headquarters to aviation infrastructure and complex real-world environments, each project required a tailored engineering approach.

The year 2025 was not defined by a single monumental facility, but by technical diversity, continuity of cooperation, and measurable operational stability.
This is precisely what defines long-term expertise in the field of air quality.
