Environmental analysis: creating negative or positive pressure zones for safer hospitals
Protecting the health of hospital occupants requires rigorous environmental management. Discover how Assek Technologies implements innovative solutions, such as negative or positive pressure zones, to limit the spread of pathogenic particles and ensure healthy and safe environments.
When it comes to protecting the health of occupants in sensitive environments like hospitals, rigorous management of air and contaminants is essential.
Assek Technologies, with its expertise in indoor environment management, applies its knowledge to create negative or positive pressure zones. These solutions limit the spread of viruses and nosocomial infections in hospital settings, ensuring the safety of both patients and medical staff.
An environmental challenge in hospitals: protection against airborne viruses
Controlling pathogenic particles has become a top priority in hospitals, especially during pandemics. Viruses can spread through respiratory droplets, contaminated surfaces, or even via the air, increasing the risk of nosocomial infections in high-risk zones.
Hospitals have turned to Assek Technologies to transform certain areas into spaces with either positive or negative pressure, isolating viruses and protecting occupants.
These environments are designed to:
- Prevent virus dispersion into adjacent areas.
- Significantly reduce contaminant concentrations through HEPA air filtration systems.
- Managing hazardous fibers : The presence of asbestos in healthcare facilities in Quebec is significant. According to the Quebec Asbestos Victims Association (AVAQ – 2024), more than 3,700 public buildings, including numerous hospitals and clinics, contain asbestos.
A technical solution: analysis and implementation of negative pressure zones
Assek Technologies deployed a comprehensive and innovative solution in several steps:
1.Environmental analysis and preventive measures:
- Sensors were installed to monitor in real-time, via the Assek IoT application, the effectiveness of pressure zones, air quality, and airborne particle levels.
- Mapping of zones helped identify areas requiring the implementation of positive or negative pressure.
2.Creation of pressure zones:
- Use of airtight barriers to confine air in specific spaces.
- Installation of HEPA filtration systems, renowned for their efficiency in capturing fine particles, including infectious aerosols.
3.Monitoring and system automation:
- Real-time monitoring tools ensured precise control of differential pressures.
- Automatic alerts were issued in the event of imbalances, enabling swift intervention.
- Automated operation of filtration, pressurization, or depressurization equipment allowed real-time adjustments.
4.Documentation and adjustments:
- All data, including pressure changes and air exchange rates, was documented and made accessible through Secur™ software.
- Systems were fine-tuned to maximize safety and efficiency.
Results: improved air quality and secure environments

Results and benefits
Assek Technologies’ intervention successfully transformed critical hospital areas into secure spaces:
- Significant reduction of airborne viruses: Achieved through HEPA filtration and strict airflow control.
- Real-time alerts: To prevent any imbalances.
- Comprehensive documentation: For continuous adjustments and accurate reporting.
These measures ensured not only the protection of patients and staff but also improved air quality in designated hospital areas.
Expertise beyond hospitals
While this intervention focused on the hospital environment, the solutions offered by Assek Technologies are also ideal for other sensitive settings, such as pharmacies, laboratories, schools, or construction sites. Challenges like dust reduction and airflow control during construction are similar and require automatic, tailored solutions for effective environmental management during projects.
For instance, protecting students’ health by minimizing dust in schools during renovations ensures a safe and healthy environment.
