Poor air quality has been proven to increase the risk of respiratory illnesses and even cancer. According to the World Health Organization (WHO), around 4.2 million deaths worldwide are linked to poor air quality and pollution.
In order to help improve air quality, it’s important to note the pollution and ozone levels in your city and take all possible measures to maintain healthy air quality, both inside and outdoors. If you live in the southernmost continental state, here’s what you need to know about Florida air quality.
Overall, air quality in Florida is a mixed bag. According to the Florida Department of Environmental Protection, there has been a steady decrease in levels of pollutants in the air for the past two decades. And currently, air pollution statewide is at an all-time low.
However, this doesn’t paint the full picture.
While pollutants are decreasing overall, Florida is a large state with many metropolitan centers. In general, large cities are much more polluted than low-population areas. So, just because the state’s overall air quality is getting better, doesn’t mean every city is improving.
Many major metropolitan areas in Florida have experienced a decline in air quality over the past year:
Although it’s still ranked as one of the most polluted cities in the country (153rd), Jacksonville saw a decrease in both particle pollution and ozone levels over the last year, which is a step in the right direction.
Ozone and particle pollution levels both increased over the last year, harming the city’s air quality considerably.
In the past year, Orlando saw the sharpest rise in both particle pollution and ozone levels than any other major city in Florida.
While particle pollution was down from 2019, ozone levels increased, leading to more unhealthy air days than in the past. Additionally, there has been a 55% increase in vehicle emissions since 1990.
Although air quality is improving in Florida overall, it depends where you live. Many populated cities (such as Orlando) are struggling to boost their air quality levels year after year.
What Affects Air Quality?
To determine the quality of the air in cities, researchers use air quality monitors to detect dangerous substances that are present in the air. These substances can be broken down into two categories:
- Particle pollution
Most particulate matter (tiny airborne particles that lodge in your respiratory system) are caused by vehicle and factory exhaust.
An invisible pollutant that chemically reacts with tissue in your lungs. It’s more commonly known as “smog.” Ozone is created when exhaust gasses like nitrogen oxide or other volatile organic compounds react with sunlight to form a molecule of three oxygen atoms (O3).
Both of these pollutants can cause lasting health effects, even in small doses.
The main source of both types of pollutants is exhaust from vehicles and factory emissions. Given that major cities such as Miami, Tampa, St. Petersburg, and Orlando are home to Florida’s manufacturing industry, these regions may be at particular risk for air quality issues.
How Does Air Quality Affect Florida Residents?
Poor air quality is known to cause serious respiratory issues such as asthma and lung disease for both older adults and children, particularly in those who are unusually sensitive to respiratory-related issues. This includes:
- Asthma attacks
- Coughing and wheezing
- Shortness of breath
- Swelling of lung tissue
- Cardiovascular damage
- Lung cancer
For sensitive groups like children and the elderly or immunocompromised, air quality can also cause developmental harm and even premature death. That’s why it’s essential to reduce pollutants like vehicle and factory exhaust to boost air quality in Florida. It’s rapidly becoming a matter of public health.
The Problem With Indoor Air Quality
Just because you go inside doesn’t mean you escape harmful outdoor air pollutants.
In many cases, indoor air quality is even worse. According to the Environmental Protection Agency (EPA), indoor environments may contain concentrations of pollutants 2 to 5 times higher than those found outdoors.
Your building’s HVAC system is your first line of defense against air quality issues, especially in a hot state like Florida where people rely on air conditioning all year round.
Traditional HVAC systems pull in air from outdoor intakes and circulate it throughout each room. This helps ventilate the building and removes pollutants that may be lingering in the air, particularly for buildings with indoor sources of contamination.
However, this poses a problem for balancing ventilation and energy efficiency. Why?
- Your building’s HVAC system pulls in outdoor air pollutants and constantly recirculates them throughout your building.
- To allow HVAC systems to work efficiently, many buildings are practically airtight to prevent cool air from escaping.
- While it might help reduce energy costs, it also doesn’t allow much ventilation.
Over time, pollutant levels can increase well beyond outdoor levels, leading to poor indoor air quality even in cleaner cities. This is called sick building syndrome, and it affects many buildings throughout the world.
Resolve Indoor Air Quality Issues with UFAD
The best way to boost indoor air quality is to increase ventilation. Unfortunately, traditional HVAC systems are designed for efficiency, not ventilation. If you want better indoor air quality, you need an underfloor air distribution system (UFAD).
UFAD systems are designed with air quality in mind. Instead of one large duct in the ceiling emitting fresh air and one more in the ceiling removing stale air, UFAD systems introduce air at the floor level and remove it at the ceiling. Overhead supply systems push clean air into dirty contaminated air at the ceiling. UFAD systems deliver clean air directly to the breathing zone at multiple places in the floor plan.
Not only does this work with the laws of physics (hot air rises), but it also means new and old air never meets. This separation of input and output means pollutants are removed from the space instead of continuously recirculated with the fresh air, leading to significantly improved indoor air quality.
This is just one advantage of UFAD systems over traditional HVAC, but it’s by no means the only benefit. Here are some more:
- Lower initial and lifecycle costs
- Up to 30% lower energy usage
- Improved air quality & circulation
- More environmentally-friendly
- Enhanced office productivity
- Easier access for maintenance/repair services
- Less intrusive to workspaces
- Greater aesthetic appeal
UFAD represents a new type of HVAC system that’s more effective, more efficient, and easier to manage than the outdated systems you might be used to.
