The Covid-19 Pandemic has brought a renewed focus on indoor air quality and its impact on health.

More than half of all commercial buildings rely on RTU (Rooftop Unit) systems that recycle air in indoor environments – and potentially place occupants at risk for increased spread of disease. No amount of social distancing can combat the impact of poor ventilation and recycled air that carries and disperses particulates.

What can building owners and managers do to ensure air quality and occupant health as workers return to office environments?

Guidance issued by the CDC recommends maintaining a healthy work environment by increasing air exchange. Use building ventilation systems to make changes such as:
  • The most important recommendation is to supply as much outdoor air as possible
  • Increase the ventilation rate in buildings
  • Increase the percentage of outdoor air that circulates into the system
  • Verifying ventilation performance with real-time CO2 monitoring
  • Ensure optimal performance of the air-handling system with demand control ventilation
  • Turn the system off while changing the filter(s) and dispose of used filters in a sealed bag
  • Increase ventilation schedules and volumes even in vacated buildings:
    • Run ventilation systems at nominal speed at least 2 hours ahead of building occupation time
    • Lower the speed 2 hours after normal occupancy ends
    • Keep the ventilation systems running at low during unoccupied hours such as nights/weekends
  • Replacing RTU systems with high-efficiency heat recovery ventilators (Net-zero or Passive House certified ERVs or HRVs). These dedicated outdoor air systems (DOAS) optimize healthy indoor air quality while minimizing building energy usage.

When safety comes first – 
experience the Ventacity difference.

Ventacity offers a complete portfolio of ultra-efficient ventilation systems that support superior air quality with true counterflow heat exchange that takes the bad air out and brings in the maximum amount of fresh air to each room while also providing energy recovery. Our best-in-class heat and energy recovery ventilation systems are designed with stringent quality assurance and quality controls, which is why Ventacity has the only Passive House certified ERV and one of a few certified HRVs available in North America. Our products have been engineered to provide easy installation, energy efficiency and durability. Our solution is ideal for high performance green buildings and those that seek to switch to 100% electrification. With a complete line of rooftop units, ceiling mount units and whisper-quiet ductless units that come in both heat recovery and energy recovery models, Ventacity enhances building health, comfort and efficiency while reducing HVAC by as much as 85%, along with operations and maintenance costs.

In addition to helping to prevent the spread of illness, healthier indoor environments also enhance cognitive performance by increasing rates of ventilation and decreasing concentrations of CO2 and other noxious compounds.

Clean Air in Buildings Challenge

Facts such as “taking actions to improve IAQ can reduce the risk of exposure to particles, aerosols, and other contaminants, and improve the health of building occupants” get everyday mention at Ventacity—so it was exciting when the White House hosted a whole webinar emphasizing IAQ for health.  Download this Clean Air in Buildings Challenge brief HERE.
