Autumn Allergens Impact IAQ

While spring allergies cause discomfort for millions of Americans across the country, fall is no slouch when it comes to triggering symptoms. Rotting leaves produce mold and ragweed release pollen during the autumn months with a peak in September. Indoors, the same culprits of dust and dander trigger symptoms. Read on to learn more about Autumn allergen's impact on IAQ as well as solutions to lessen their effect. What Are Indoor Allergens? What are the autumn allergens impacting IAQ? For the most part, they’re the same things that affect IAQ all year round. We track dirt, pollen, leaves, and other organic matter inside buildings when we enter. Of course, the main indoor allergens of dust mites, pet dander, and cockroaches are already there. Airborne allergens travel through the building and can trigger asthma and allergy symptoms in building occupants. These tiny particles also settle on furniture, carpeting, and other surfaces. Once disturbed, they get sent airborne once more. Thorough cleaning reduces the number of allergens both at home and in the office. The Impact of Autumn Allergens ...

HVAC Affects IAQ in 3 Ways

The pandemic stressed the need for creating and maintaining healthy indoor conditions to keep building occupants safe. How HVAC affects IAQ, however, is something facilities managers always need to stay on top of. What follows are three ways HVAC affects IAQ as well as solutions for keeping the indoor environment safe for all. Three Ways HVAC Affects IAQ HVAC affects IAQ in preventable ways. Avoiding the negative consequence of poor indoor air quality is affordable and saves money over the long term. Here are three common issues of HVAC that affects IAQ in buildings.  The Problem #1: Clogged Coils One way HVAC affects IAQ is through clogged coils. Over time, evaporator coils become fouled. Dust, dirt, soot, and other debris clog the coil and prevent it from operating as it should. Due to the moisture collecting in the AHU, this dirt sticks to the coil fins and builds up fast. The more debris lodged in the coils, the harder the system must work to provide clean air to the building. This affects indoor air quality, of course, ...

HVAC Insulation and Building IAQ

Building occupants are concerned with their health as it relates to the indoor environment. The ongoing pandemic only highlights the need for addressing IAQ issues. While anxiety about the spread of airborne viruses is high, other aerosols pose a threat to our health indoors as well. For example, how HVAC insulation affects IAQ is a question many facilities managers need to address in their buildings. What is Fiberglass HVAC Insulation? Fiberglass is in the insulation of most residential homes. It keeps buildings cool in the summer and warm in the winter. It’s placed behind walls and above ceilings. It insulates ventilation ducts as well as the air handling units (AHU) of HVAC systems. The fine glass fibers used to make insulation degrade over time. Fibers come loose and travel through the air where oftentimes they get taken into the lungs. Of particular concern is the exposed fiberglass insulation found inside air handling units (AHU). When this material gets damp it sags and breaks down. The result is the distribution of fiberglass particles into the air stream. Not ...

School Mold Testing, What You Need to Know

With students heading back to the classroom, concerns about safety return as well. While the threat of COVID eases, other indoor air quality risks remain. For example, periods of high humidity in closed buildings over the summer allowed mold a chance to spread. This makes school mold testing a top priority for administrators. In much of the country, temperatures remain high well into the fall season. With building occupancy low over the summer break, ventilation systems ran less. This allowed mold to flourish as current conditions provide an ideal environment for the fungus to spread. As students and staff return the increase in traffic disperses mold spores throughout the building. That creates a health risk. While school mold testing is a way to determine the presence of mold, a complete HVAC health check protects against future growth. School Mold Testing While mold performs a valuable service breaking down organic matter in nature, indoors it poses a health risk. Even so, detection is not easy. Mold grows inside building materials in the walls, ceiling, and floors. Changes in ...

Commercial Roof Leaks Affect IAQ

That leak in the roof of your building seems like a small problem right now. Letting it go unrepaired, however, leads to bigger problems down the line. One major reason for concern is that roof leaks affect IAQ. Taking care of commercial roof leaks early prevents them from developing into health risks for employees. It also improves the overall efficiency of the ventilation system. Commercial Roof Leaks With the many challenges facing facilities managers in this age of pandemics and tight budgets, commercial leaks often get moved to the back burner. However, addressing issues that affect the building envelope prevents health hazards from developing. It also lowers energy costs. Since roof leaks affect IAQ in buildings, this adds a sense of urgency to the situation. A leak management program is the best way to protect buildings from damage. It allows building owners to prevent roof issues from developing into major problems. It extends the lifecycle of roofs too. Commercial Roof Leaks Affect IAQ Of course, commercial roof leaks cause property damage. Even a small amount of water ...
