A premiere in Brussels: "The lungs in the city"

Parking ‘2 Portes’ in Brussels is the first representative of a new generation of car parks. It was recently equipped with a new system for neutralising fine particles that purifies the ambient air and makes it less harmful to health. Parking 2 Portes will thus become a real lung in the city.

Fine dust particles are harmful to the health of people exposed to them. They are invisible to the naked eye, but can be inhaled and eventually cause respiratory and cardiovascular diseases.

To remedy this situation and to ‘purify the air’ in its car parks, Interparking is introducing an innovative system that neutralises up to 70% of particles, up to 40% of fine particles and up to 20% of ultra-fine particles in Parking 2 Portes in Brussels. Developed by ENS Clean Air in cooperation with the University of Maastricht in the Netherlands, this technology uses the positive ionisation process to retain fine particles in the ambient air. The effectiveness of the system inside the parking has been validated by the independent air quality monitoring company Airscan.org. Interparking thus aims to reduce its ecological footprint and that of its customers while striving for an environmentally friendly mobility mix adapted to the mobility needs of the inhabitants of Brussels. Interparking is convinced that the solution to environmental problems has to be based on constructive cooperation between companies, local authorities and citizens. The principle is very simple. In a first phase, the polluted air is sucked into a system that gives the fine dust particles a positive electrical charge. The particles then bind together to form larger particles. These larger particles then move towards a collector plate which immobilises them and converts them into coarse dust. Stripped of the polluting particles, the purified air is finally blown out of the system.

Once converted to coarse dust, the particles can no longer be transported into the air or inhaled and are collected for destruction in a specialized centre.

“Interparking meets the challenges of social and environmental responsibility in many ways,” Roland Cracco, CEO of Interparking underscores. “We believe that a positive impact on society and the environment is part of our mission”.

In 2018, Interparking also signed the first “Green Loan” in Belgium with BNP Paribas Fortis, a loan whose interest rate is linked to performance and the achievement of sustainability objectives such as the reduction of the carbon footprint per full-time equivalent and the reduction of energy consumption.

About Airscan

Airscan.org is an independent air quality measurement, monitoring and warning company. Its expertise and technology (developed by CNRS) enables companies and government agencies to measure indoor and outdoor pollution for better air quality decisions. The most commonly measured pollutants are PM10, PM2.5, VOC, NO2, CO2, formaldehyde, trichloramine, radon, O3… Airscan.org is a sister company of CO2logic.

Technical data provided by ENS Clean Air. The measurements of PM 2.5 particles carried out by Airscan.org in Parking 2 Portes are between 44% and 50% lower.

Example of the positive effects of the ENS Clean Air system on PM2.5 particles. The ENS Clean Air system can improve the air quality in a car park significantly. After treatment, the air inside Parking 2 Portes (green bar) is not only healthier than the air inside the car park before treatment (orange bar), but also better than the outside air (blue bar).

Airscan Launches Air Quality Campaign in Brussels

From the 1st to the 14th of February, Airscan launched an air quality campaign in Brussels. For two weeks, air quality was measured at 8 different locations in the same number of municipalities of the capital. With this campaign, Airscan wants to shed light on the importance of clean air, especially in a busy city such as Brussels.


Airscan Obtains ISO 17025 Accreditation

Airscan celebrates a successful 2023 with international expansion and achieving BELAC accreditation for ISO/IEC 17025:2017, recognizing their commitment to high-quality services. The accreditation enhances credibility and positions Airscan as a trusted partner for Real Estate clients pursuing Green Building certifications.


Back To School: “Clean Air for our Kids” project by Airscan and Belfius

Today we celebrate the restart of the academic year. Already as a tradition, this year our team will continue helping schools all around Belgium with Indoor Air Quality monitoring and improvement. Discover more about “Clean Air for Our Kids” project in our last video, recorded in the Open Air School in Schilde at the end of the last academic year.
