IAQ Tax Credits May Come Sooner Than You Think

Business owners and facilities managers have concerns about maintaining and upgrading their HVAC systems. They recognize the many benefits proper IAQ provides to employees such as improved health and limiting the spread of viruses. That said, they also worry about the impact these upgrades and repairs have on operating costs. However, the truth is that improving the efficiency of ventilation systems lowers operating costs as it improves IAQ. This alone should give stakeholders a reason to make changes, but another way to ease the financial pain is through federal tax incentives. This is what Representative Don Beyer (D-Virginia) proposed to Congress in June. Rep. Beyer’s Airborne Act legislation offers IAQ tax credits to any commercial building owner who addresses IAQ through assessments and upgrades to their HVAC systems.   IAQ Tax Credits As an IAQ firm in business since 1984, Pure Air Control understands the many cost benefits related to improving indoor air quality. For starters, a more efficient system provides cleaner air to building occupants. A clean system also costs less to operate. Repair and replacement costs ...

Healthy Green Buildings: What It Takes to Get There

As more people return to the workplace post-pandemic, this means more time is spent in buildings with potentially unhealthy indoor air. It’s a health concern when working in the modern workplace. Open floor plans, conference rooms, and shared office spaces create a level of risk. However, if facilities managers work to create sustainable indoor conditions this leads to healthier employees. So the thinking goes anyway, but when companies devote millions of dollars to sustainability concepts in design and construction, in the end, are green buildings healthy? It depends on a few factors and LEED certification is one of them. What is a Healthy Green Building? A green building reduces the negative impacts on the environment. This includes the use of sustainable materials in construction, reducing energy costs, using fewer natural resources, and generating less pollution as a result. If the goal of a green building is to create a positive impact on the environment, that should include the people that inhabit that environment. This makes the health and safety of building occupants key considerations in any green ...

Ventilation System Cleaning Critical for Building Health

The science is clear. Healthy indoor air means healthier building occupants. The COVID pandemic puts this into sharp focus for building managers. When ventilation systems don’t do their job of providing clean, healthy air building staff and visitors suffer as a result. This is why a ventilation system cleaning system is critical to maintaining healthy buildings. The Health Impact of a Ventilation System Cleaning Stale, unclean air impacts the health of building occupants. This includes patients and staff at medical facilities, visitors to retail businesses, and workers in office buildings. It is also true in residential buildings and homes. Air that is filled with particulate matter, such as dust particles and volatile organic compounds, enters the lungs and causes inflammation. This also triggers asthma and allergy symptoms. Long-term exposure to particulates leads to more serious health issues such as respiratory and cardiovascular diseases. Studies also show that students exposed to poor IAQ have more difficulty with cognitive functioning. Conversely, better IAQ leads to higher test scores. In office buildings, poor IAQ leads to more missed work days, ...

How Water Intrusion Affects IAQ

You may not think water intrusion affects indoor air quality, but it does. When water enters the building undetected it creates an ideal environment for mold to grow and thrive. It also allows outside contaminants into the building. This impacts the health of building occupants both at home and in the workplace. Therefore, building managers and homeowners must guard against excess moisture indoors.  Water Intrusion Affects IAQ The threat of water intrusion keeps facilities managers up at night. Sometimes the problem is difficult to detect and an issue isn’t discovered until a problem arises. When water intrusion affects IAQ in the form of mold, this triggers allergy symptoms in building occupants. Long-term mold exposure leads to serious health problems such as asthma and respiratory infections, allergic rhinitis, bronchitis, and eczema. Dampness also attracts insects and rodents and could release VOCs in building materials. Causes of Water Intrusion Water intrusion occurs for several reasons. For example, leaks around windows and doors create problems. Roof leaks and cracks in the building’s foundation also allow moisture into the building. Pooling ...

Static Pressure Affects Airflow

It’s important to keep HVAC equipment clean and free of built-up dirt and debris. Hygienic duct cleaning and the disinfection of system components are also key to achieving proper indoor air quality. While this step assists facilities managers in their efforts to maintain healthy IAQ for occupants, static pressure is another consideration. Static pressure is used in the area of fluid mechanics. Put simply, it’s the resistance to airflow that occurs in HVAC ductwork and within the system itself. When static pressure is too high or low, this reveals a problem within the system. Identifying a problem allows managers to schedule repairs before a more serious problem occurs. It keeps the system running at peak performance which lowers operating costs. It also lengthens the lifespans of equipment. Static Pressure and How It Affects HVAC Systems From heating and cooling systems in the home to large HVAC units in commercial buildings, these systems all transport air. The ductwork also is the path for airflow in the system. The correct installation of these systems ensures proper operation. However, resistance ...
