Strategies and HVAC systems & technologies under the ‘new normal’ post-pandemic

The COVID-19 pandemic has irrevocably altered our lives, including how we approach spaces and their air quality. The “New Normal” demands innovative strategies and advanced HVAC systems and technologies to prioritize health, safety, and well-being in buildings. Key strategies for the new normal:

Enhancing Indoor Air Quality (IAQ):

• Increased Ventilation: Introduce more outdoor air, potentially doubling ventilation rates, to dilute and remove airborne contaminants.
• Filtration Upgrades: Employ High-Efficiency Particulate Air (HEPA) filters to capture even minute particles like viruses.
• UV-C Disinfection: Utilize ultraviolet C light to inactivate airborne pathogens in occupied spaces.
• CO₂ Monitoring and Control: Monitor and maintain CO₂ levels below 1,000 ppm to mitigate the risk of viral transmission.

Touchless Controls and Automation:

• Implement touchless sensors and voice-activated controls for thermostats, lighting, and other building systems to minimize surface contact.
• Automate air handling and filtration systems for continuous air quality management.

Occupancy-Based Control:

• Utilize sensors and smart systems to adjust HVAC operation based on real-time occupancy levels, optimizing energy use and preventing unnecessary air circulation in empty spaces.

Building Management Systems (BMS):

• Integrate HVAC systems with comprehensive BMS for centralized monitoring, control, and data analysis to optimize performance and identify potential issues.

Innovative HVAC systems and technologies

• Bi-polar Ionization: Generates negative and positive ions that attach to airborne particles, causing them to clump and fall out of the air, improving IAQ.
• Displacement Ventilation: Introduces cool air at low velocity near the floor, pushing out warm, contaminated air towards the ceiling for removal, enhancing ventilation effectiveness.
• Heat Recovery Ventilators (HRVs): Transfer heat from exhaust air to incoming fresh air, reducing energy consumption while maintaining comfortable temperatures.
• Demand-Controlled Ventilation (DCV): Adjusts ventilation rates based on real-time CO₂ or occupancy sensor data, optimizing energy use and IAQ.
• Air Purification Systems: Advanced air purifiers with HEPA filters, UV-C light, and activated carbon filters remove a wide range of pollutants from indoor air.

Additional considerations

• Regular Maintenance and Cleaning: Frequent maintenance of HVAC systems and thorough cleaning of building surfaces are crucial to maintain optimal IAQ and prevent the spread of pathogens.
• Communication and Transparency: Building owners and managers should openly communicate implemented strategies and adopted technologies to occupants, fostering trust and confidence.

By embracing these strategies and adopting innovative HVAC systems and technologies, we can create safer, healthier, and more energy-efficient buildings for the ‘New Normal’ post-pandemic world.
