How HVAC Impacts COVID-19 Transmission

HVAC impacts COVID-19 transmission in a few different ways. Pathogens, like the coronavirus that causes COVID-19, spread by inhaling infected airborne droplets. This transmission also results through contact with high-touch surfaces such as door handles, railings, and countertops. Scientists also believe that the coronavirus spreads through aerosol transmission. This occurs when the virus gets dispersed in tiny droplets of water. When the infected person coughs, sneezes, or talks loudly, these droplets travel at great speeds through the air. For example, as many as 30,000 of these particles get released in a single sneeze. Once released, these droplets attach to airborne particles such as dust. As a result, the risk of indoor infection increases. If the coronavirus gets spread through aerosol transmission, the question becomes, do HVAC systems circulate this airborne pathogen throughout the indoor environment? If it does, then how HVAC impacts COVID-19 becomes even more important to understand. Indoor Coronavirus Transmission In the early stages of the pandemic, the World Health Organization (WHO) declined to recognize the aerosol transmission of the virus. This prompted a response ...

The Future of Healthy Buildings IAQ

Increased emphasis on health and wellness is an ongoing trend in the corporate world. Because of this, the commercial real estate market must change to meet new demands as the focus on healthy buildings IAQ impacts employers and staff as well. Healthy buildings keep occupants healthy. For employers, healthy workers have higher morale and are more productive. Maintaining good indoor air quality is key to creating healthy indoor environments. One way to increase building health is by repairing and replacing outdated HVAC systems. Smart building engineers also take advantage of solutions like IAQ guard remote monitoring to detect high CO2 levels and to protect against the spread of viruses, such as the coronavirus that causes COVID-19. Healthy building IAQ is not only important for the health of workers, but also for students at universities, patients in healthcare facilities, and anyone who spends time indoors. Above all, it’s important for the health of the entire US economy because it limits the risk of infectious outbreaks that shut businesses down. The Dangers of Unhealthy Buildings Many dangers exist in ...

How Coronavirus Impacts Schools Reopening

School administrators, faculty, and parents all want the same things for their students. They want to get them back in school learning. Even so, safety concerns during the ongoing COVID-19 pandemic remain a top concern for schools across the country. While children have a lower risk of getting COVID-19 than adults, they can bring the virus home with them. This poses a risk to elderly family members and those with underlying health conditions. Teachers and staff remain vulnerable in schools as well. As a result, building engineers, maintenance staff, and other stakeholders face challenges in the ways coronavirus impacts schools this fall. Outdated Mechanical Systems Outdated or underperforming mechanical systems is a big problem facing school reopening plans. A recent study by The Government Accountability Office (GOA) found that more than half of the nation's school districts have outdated building systems. Forty percent of these 13,000 school districts need new or updated HVAC systems in at least half of the schools in their systems. As a result, almost 40,0000 schools across the U.S. face issues of poor ...

Large Volume HEPA Fights Coronavirus

Indoor air quality has always been a concern for building and facilities managers. The ongoing COVID-19 pandemic only highlights the need for safety in the indoor environment. This includes choosing the correct filters and maintaining them. For example, it's recommended that HEPA fights coronavirus the best of all filter products. However, removing contaminated filters is a messy job that exposes building engineers and maintenance staff to potential contamination. Large volume HEPA air filters are an effective way to rid the air of mold, dust, bacteria, and pathogens without requiring staff to change out dirty filters. A variety of facility types use large volume HEPA filtration. This not only includes in hospitals and aircraft cabins, but retail environments, auditoriums, and office settings as well. They are key in preventing the spread of airborne viruses as large volume HEPA fights coronavirus which causes COVID-19. HEPA Fights Coronavirus Air that is free from contamination is important for the health and safety of building occupants. So, large-volume HEPA filtration machines alleviate concerns about indoor air quality. These devices are used in ...

How Bipolar Ionization Improves IAQ

As facilities and building managers confront the realities of the COVID19 pandemic, better methods and tools become available to keep buildings safe. For instance, increased cleaning and disinfecting schedules limit the risk of infection. Regular maintenance and repairs to HVAC systems keep systems running at top performance. But, real-time, persistent air purification gives building engineers an edge in maintaining good indoor air quality. Therefore, bipolar ionization improves IAQ by attacking and killing airborne viruses within shared spaces. Aerosol Transmission of Coronavirus Understanding how airborne viruses travel is important in limiting their spread. For example, we know coronavirus spreads through the mouth when coughing, sneezing, and talking. Up to 30,000 droplets, invisible to the naked eye, get produced from a single sneeze. These droplets travel at speeds up to 60 miles per hour. Researchers are now beginning to understand how these droplets attach themselves to aerosols already in the air to create even more risk for staff and building visitors. One study published in the New England Journal of Medicine found that coronavirus can live in an aerosol ...
