Historical Context
Sick Building Syndrome (SBS) emerged as a recognized phenomenon in the 1970s following the oil crisis, which led to the construction of more energy-efficient buildings with limited ventilation to conserve energy. This inadvertently resulted in a decrease in indoor air quality.
Definition
Sick Building Syndrome (SBS) refers to a situation where occupants of a building experience acute health effects that seem to be linked to time spent in the building, with no specific illness or cause identified. Symptoms often improve after leaving the building.
Causes
Several factors contribute to SBS, including:
- Poor Ventilation: Lack of adequate ventilation leads to the accumulation of pollutants.
- Chemical Contaminants: Emissions from building materials, furniture, and cleaning products.
- Biological Contaminants: Mold, bacteria, and viruses.
- Electromagnetic Radiation: Exposure from electronic devices and wiring.
Symptoms
Common symptoms include:
- Headaches
- Eye, nose, and throat irritation
- Dry cough
- Itchy skin
- Dizziness and nausea
- Fatigue
- Difficulty concentrating
Key Events
- 1970s: Increased awareness due to the oil crisis and energy-efficient building designs.
- 1984: WHO reports highlighted the global prevalence of SBS.
- 1990s: Advances in building materials and HVAC systems to improve indoor air quality.
Detailed Explanations
SBS is often a result of a combination of indoor air pollutants, inadequate ventilation, and poor building maintenance. It is not related to a specific illness and the symptoms usually subside when the person leaves the building. The condition highlights the importance of indoor air quality in maintaining occupant health and well-being.
Mathematical Models and Formulas
SBS can be studied using Indoor Air Quality (IAQ) models, which take into account factors like:

Importance
Understanding SBS is crucial for architects, builders, and facility managers to ensure buildings are constructed and maintained to support occupant health, thereby improving productivity and reducing absenteeism.
Applicability
- Corporate Offices: Improve productivity and reduce sick leave.
- Schools and Universities: Enhance learning environments.
- Hospitals: Ensure the health of patients and staff.
- Residential Buildings: Improve the living quality for occupants.
Examples
- Case Study: The Environmental Protection Agency (EPA) headquarters once had issues with poor indoor air quality, which were addressed by improving ventilation systems and reducing indoor pollutants.
Considerations
- Regular maintenance of HVAC systems.
- Use of low-emission building materials.
- Regular monitoring of indoor air quality.
- Ensuring adequate ventilation.
Related Terms
- Building-Related Illness (BRI): Illness directly attributable to airborne building contaminants.
- Multiple Chemical Sensitivity (MCS): Sensitivity to various environmental chemicals.
Comparisons
- SBS vs. BRI: SBS is a set of non-specific symptoms, whereas BRI refers to specific diagnosable illnesses.
- SBS vs. MCS: MCS is a chronic condition triggered by chemical exposure, while SBS symptoms are acute and often temporary.
Interesting Facts
- Fact: The term “Sick Building Syndrome” was coined by the WHO in the early 1980s.
- Fact: Indoor air pollution can be 2 to 5 times higher than outdoor pollution.
Inspirational Stories
- Story: A tech company once facing high employee turnover discovered the cause was poor indoor air quality. By revamping their HVAC system and using green building materials, they significantly improved employee satisfaction and productivity.
Famous Quotes
- Quote: “Healthy buildings equal healthy people.” – Dr. Joseph Allen
Proverbs and Clichés
- Proverb: “A healthy home is a happy home.”
Expressions, Jargon, and Slang
- Expression: “This office is making me sick!”
- Jargon: “IAQ” - Indoor Air Quality
- Slang: “Bad air day” - A day when indoor air quality is poor
FAQs
Q1: How can I tell if my building has SBS? A1: If multiple occupants experience similar symptoms that improve upon leaving the building, SBS may be present.
Q2: What steps can I take to improve indoor air quality? A2: Increase ventilation, use air purifiers, regularly clean HVAC systems, and use low-emission materials.

Summary
Sick Building Syndrome (SBS) is a condition where building occupants experience acute, non-specific health effects linked to time spent in a building. It underscores the importance of good indoor air quality and proper building maintenance. By understanding and addressing the causes of SBS, we can create healthier indoor environments that promote well-being and productivity.
