TL;DR:
- Sick Building Syndrome (SBS) causes health issues for people inside a building.
- Symptoms like headaches, fatigue, and respiratory problems are common.
- Poor indoor air quality from pollutants is the usual culprit.
- Diagnosis involves symptom tracking and environmental testing.
- Improving ventilation and removing pollution sources are key solutions.
What Is Sick Building Syndrome and How Is It Diagnosed?
Have you ever felt unusually unwell when you’re at work or home, only to feel better when you leave? This could be a sign of Sick Building Syndrome (SBS). It’s a recognized issue. Many people experience it without knowing the cause. We’re here to help you understand what SBS is and how it’s diagnosed.
Understanding Sick Building Syndrome
Sick Building Syndrome is a term used when building occupants experience symptoms of illness or discomfort. These symptoms are directly related to the time they spend inside a particular building. The effects seem to improve or disappear when they leave the building. It’s not a specific disease. It’s more of a collection of symptoms tied to a place.
Common Symptoms of SBS
Symptoms can vary widely among individuals. However, some common complaints include:
- Headaches
- Fatigue and dizziness
- Nausea
- Difficulty concentrating
- Irritation of the eyes, nose, and throat
- Dry or itchy skin
- Respiratory problems like coughing or shortness of breath
These symptoms can feel like a cold or flu. But they persist as long as you’re in the building. This can be incredibly frustrating and impact your daily life. It’s important to note that not everyone in the building will be affected. Some individuals may be more sensitive to the environmental factors.
What Causes Sick Building Syndrome?
The root cause of SBS is generally linked to poor indoor air quality. Several factors can contribute to this. These can include pollutants from inside and outside the building. Identifying the specific source is key to finding a solution. Sometimes, the problem is not immediately obvious. You might be dealing with interstitial condensation inside walls without even knowing it.
Indoor Air Pollutants
Many common building materials and activities release volatile organic compounds (VOCs). These can come from paints, cleaning supplies, furniture, and carpets. Biological contaminants like mold and bacteria can also be present. These thrive in damp environments.
Inadequate Ventilation
Modern buildings are often designed for energy efficiency. This can mean tighter construction. While good for saving energy, it can trap pollutants inside. If ventilation systems aren’t properly maintained or designed, fresh air doesn’t circulate effectively. This allows pollutants to build up.
HVAC System Issues
Heating, ventilation, and air conditioning (HVAC) systems play a big role. Dirty filters, ductwork, or poor system design can spread contaminants. Mold can grow in damp areas of the HVAC system. This then circulates throughout the building.
Other Contributing Factors
Sometimes, factors like poor lighting or uncomfortable temperatures can add to occupant discomfort. These can exacerbate the feelings associated with SBS. Even issues like stair-step cracking in brick could indicate underlying structural issues that affect airflow or moisture.
Diagnosing Sick Building Syndrome
Diagnosing SBS can be a complex process. It requires a systematic approach. Since there’s no single test, doctors and building scientists look at a combination of factors. They need to confirm that the building is the likely cause.
Step 1: Symptom Assessment
The first step is carefully documenting symptoms. This involves noting when symptoms appear, what they are, and when they go away. Keeping a detailed log can be very helpful. This information helps establish a pattern related to building occupancy. It’s important to rule out other medical conditions that might cause similar symptoms. A doctor’s evaluation is essential.
Step 2: Environmental Evaluation
Once medical causes are ruled out, the focus shifts to the building. This involves a thorough inspection. Building professionals will look for potential sources of contamination. They will assess ventilation rates and air quality. This might involve testing for specific pollutants.
Air Quality Testing
Air sampling can detect the presence of mold spores, bacteria, VOCs, and other airborne irritants. Testing can be done in different areas of the building. This helps pinpoint problem zones. We found that sometimes, the issue is related to moisture control, like ensuring how do I know if my vapor barrier is working? correctly.
Ventilation System Assessment
The HVAC system is a prime suspect. Experts check if it’s functioning correctly. They look for adequate fresh air intake and proper exhaust. They also check for cleanliness and maintenance issues.
Identifying Pollution Sources
This involves a detailed walkthrough. Inspectors look for sources of chemical off-gassing, biological growth, or other contaminants. They might examine building materials, cleaning practices, and office equipment.
Step 3: Correlating Symptoms and Environment
The final step is to connect the dots. If occupants’ symptoms consistently improve when they leave the building and worsen when they return, it’s a strong indicator. If environmental testing reveals elevated levels of pollutants or poor ventilation, the link becomes clearer. It’s important to remember that insurance companies might try to downplay issues. Understanding documents like a reservation of rights letter from an insurer can be helpful in complex situations.
When to Seek Professional Help
If you suspect SBS, don’t ignore it. Your health and well-being are important. Persistent symptoms can significantly affect your quality of life. It’s also important to consider that underlying issues could lead to more serious problems over time. For example, poor drainage can lead to water intrusion, and why does landscaping slope matter for home drainage? is a critical question to ask.
Checklist for Suspected SBS
- Keep a detailed log of your symptoms.
- Note when symptoms appear and disappear.
- Consult a medical professional to rule out other illnesses.
- Document any unusual odors or visible signs of mold.
- Report your concerns to building management or HR.
- Consider professional indoor air quality testing if concerns persist.
Solutions for Sick Building Syndrome
Once SBS is diagnosed, the focus shifts to remediation. The goal is to improve indoor air quality and eliminate the sources of pollutants. Solutions often involve a combination of strategies.
Improving Ventilation
Increasing the amount of fresh air entering the building is crucial. This can involve adjusting HVAC systems, opening windows (where appropriate), and ensuring exhaust fans are working properly.
Source Control
Identifying and removing or controlling the sources of pollution is key. This might involve using low-VOC products, improving cleaning practices, or repairing leaks that cause moisture problems.
Air Filtration and Purification
Using high-efficiency air filters in HVAC systems can capture many airborne particles. Air purifiers can also help remove specific pollutants from the air.
Moisture Control
Controlling humidity levels and promptly addressing any water damage is vital. This prevents mold and mildew growth, which are common SBS contributors.
Conclusion
Sick Building Syndrome can be a challenging issue, affecting both health and productivity. Understanding its causes, symptoms, and diagnostic process is the first step toward finding relief.

What are the most common types of pollutants found in sick buildings?
The most common pollutants include volatile organic compounds (VOCs) from building materials and furnishings, carbon monoxide, mold and mildew spores, dust mites, and outdoor pollutants that enter the building. These can all contribute to poor indoor air quality.
Can a doctor diagnose Sick Building Syndrome?
A doctor can help diagnose SBS by ruling out other medical conditions. They can identify symptoms associated with SBS. However, a definitive diagnosis often requires assessment by building scientists or environmental health specialists who evaluate the building itself.
How long does it take to recover from Sick Building Syndrome?
Recovery time varies. Many people feel symptom relief shortly after leaving the affected building. Full recovery can take days or weeks, depending on the severity of exposure and individual sensitivity. Continued exposure will prolong symptoms.
Is Sick Building Syndrome the same as mold illness?
Mold illness is a specific condition caused by exposure to mold toxins. Sick Building Syndrome is a broader term. It encompasses a range of health effects linked to poor indoor air quality. Mold can be one cause of SBS, but SBS can also be caused by other factors like VOCs or inadequate ventilation.
What should I do if my employer doesn’t address Sick Building Syndrome concerns?
If your employer is unresponsive, you may need to escalate your concerns. Document everything thoroughly. Consider consulting with a health and safety professional or your local health department. In some cases, legal advice might be necessary, especially if you receive a reservation of rights letter from an insurer that seems to complicate the situation.
