Understanding the causes and symptoms of SBS, can not only help workers and building managers take steps to resolve the problem, but also drive home the importance of good indoor air quality in commercial buildings.
What is the number one cause of SBS?
Inadequate building ventilation is the most common cause; the appearance of SBS in the mid-1970s has often been attributed to decreased ventilation standards for commercial buildings to increase energy efficiency, following the Arab oil embargo of 1973.
Why is sickness in a building bad?
However, sickness of buildings results from a group of factors associated with effects of high concentrations of toxic pollutants present inside the building. In many cases, occupant’s behaviors such as closing windows while using ACs in summer or central heating system in winter leads to an unhealthy indoor atmosphere due to poor ventilation,. Furthermore, poor building design, maintenance, and/or operation of the structure’s ventilation system may also be at fault.
What is Sick Building Syndrome?
Sick Building Syndrome (also know as SBS) is used to describe situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified. SBS occurs mostly in office buildings however, it may also occur in other public buildings such as schools and libraries. According to the USEPA, sickness of buildings is highly suspected when the following conditions are present:
What are the physical factors that affect the temperature of a room?
Major physical factors involved are weakness of ventilation, high temperatures, fluorescent lighting and electrical equipment, change in temperatures during the day, low humidity, poor lighting, dust, and use of display screens for long hours.
What are the causes of SBS?
Poor sanitary and cleaning practices, especially in public facilities, lead to the accumulation of biological contaminants such as pollen and dust mites’, fungi, mold, and bacteria from the toilet. Besides, insect body parts are particularly troublesome allergens and are commonly implicated as contributors to SBS.
Why is the environment important?
Environment is not only important for its own sake, but also as a resource for healthier living conditions and well-being. Poor environmental quality and its current and future impact on human health is a significant concern worldwide. Air pollution causes significant health problems. In fact, knowledge about the links between health and air quality has considerably improved in the last few decades. According to a WHO report, more than 30% of new and renovated buildings worldwide may generate severe complaints related to indoor air quality. Here’s everything you need to know about sickness of buildings:
How do I know if I have Sick Building Syndrome?
The technical definition is simply one of symptoms, connection to the “cause,” and overall numbers. Sick Building Syndrome symptoms are more non-descript and general than BRI symptoms, and the (known or suspected) cause of SBS symptoms is unknown. SBS symptoms generally subside quickly after having vacated the sick building, while BRI symptoms may persist for days, weeks or even longer, after having left the building. If more than 20% of occupants are suffering SBS symptoms and there is no known source of the discomfort, then you may have a “sick building.”

What Causes Sick Building Syndrome?
There is a range of problems behind sick building syndrome, and these can strike residential homes, offices, and larger workspaces. Included in the causes of this condition are:
Why is indoor air quality poor?
When the indoor air quality is poor because of factors like mold and other toxic chemicals, many of the same symptoms apply. One of the biggest problems with identifying and diagnosing sick building syndrome is that there are so many symptoms, many of which can be linked to other illnesses and conditions.
What are the causes of mold?
Various types of mold can exist in the average household, and the three main pathogenic mechanisms it causes are toxicity, infection, and allergy. For those who are sensitive to allergens or have other medical conditions, the presence of this mold can be more than just a nuisance; it can cause many serious side effects.
How to tell if you have mold?
Unlike some other chemicals and pollutants, mold can be easier to detect on your own. The presence of mold is usually determined by a smell at first , and it can be similar to a damp forest, old socks, or wet clothes, with people noticing different aromas and having their own reactions to it.
What are the health impacts of SBS?
Health Impacts of SBS and Mold. When left to their own devices, issues like mold, asbestos, and chemical paint can lead to serious health impacts. Some people will live or work for years in a home or building that has these problems, and not even realize that they’re the cause of their medical problems.
Is mold a problem?
Among its contributors, mold is one of the biggest problems and an issue that many average households and workplaces deal with today. Sick building syndrome may affect a singular room or an entire zone, with the most obvious symptom being the sick people that inhabit it.
Is mold a SBS?
When it comes to sick building syndrome, mold is one issue commonly associated with it. Although there is some debate over what constitutes SBS whether it’s the house structure itself or what’s done inside of it, what is known is that the presence of mold is an established cause of human disease.
Why are sick buildings linked to Norovirus?
Norovirus has also been linked with buildings because of "the small inoculum required to produce infection (<100 viral particles), prolonged viral shedding, and its ability to survive in the environment." Many norovirus outbreaks have been traced back to cruise ships with food service in unsanitary conditions, or filthy personal hygiene around the toilet.
Why are there gender differences in sick building syndrome?
There might be a gender difference in reporting rates of sick building syndrome, because women tend to report more symptoms than men do. Along with this, some studies have found that women have a more responsive immune system and are more prone to mucosal dryness and facial erythema. Also, women are alleged by some to be more exposed to indoor environmental factors because they have a greater tendency to have clerical jobs, wherein they are exposed to unique office equipment and materials (example: blueprint machines, toner -based printers), whereas men often have jobs based outside of offices.
What is SBS in health?
Sick building syndrome ( SBS) is a condition in which people in a building suffer from symptoms of illness or become infected with chronic disease from the building in which they work or reside. The outbreaks may or may not be a direct result of inadequate cleaning or inappropriate cleaning methods. SBS has also been used to describe staff concerns in post-war brutalist-style buildings with misplanned building aerodynamics, defects in the construction materials or assembly process and-or inadequate maintenance. Certain symptoms tend to increase in severity with the time people spend in the building; often improving over time or even disappearing when people are away from the building. Exposure to toxic black mold might be a problem. SBS is also used interchangeably with "building-related symptoms", which orients the name of the condition around patients symptoms rather than a "sick" building. A 1984 World Health Organization (WHO) report suggested up to 30% of new and remodeled buildings worldwide may be subject of complaints related to poor indoor air quality. Other causes have been attributed to contaminants produced by outgassing of some types of building materials, volatile organic compounds (VOC), molds (see mold health issues ), improper exhaust ventilation of ozone (byproduct of some office machinery), light industrial chemicals used within, or lack of adequate fresh-air intake/air filtration (see minimum efficiency reporting value ).
What are the effects of aerosols on humans?
Building occupants complain of symptoms such as sensory irritation of the eyes, nose, or throat; neurotoxic or general health problems; skin irritation; nonspecific hypersensitivity reactions; infectious diseases; and odor and taste sensations. Exposure to poor lighting conditions has led to general malaise.
What are the symptoms of a building occupant?
Building occupants complain of symptoms such as sensory irritation of the eyes, nose, or throat; neurotoxic or general health problems; skin irritation; nonspecific hypersensitivity reactions; infectious diseases; and odor and taste sensations.

The key to discovery is the increased incidence of illnesses in general with onset or exacerbation within a fairly close time frame – usually within a period of weeks.
Is sick building a vector for SARS?
However, there have been inconsistent findings on whether air conditioning systems result in SBS or not. More recently, sick building was confirmed as a vector for the transmission of SARS in 2003.
Why are buildings air tight?
In the 1970s, there was a movement amongst builders and regulatory authorities to button-up buildings to save on fuels for heating and air conditioning. Many buildings became virtually air-tight. According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers, some polluting factors include indoor combustion (heaters, ranges, smoking) and buildup of carbon monoxide and inhalable particles; volatile organic compounds such as benzene, styrene, and other solvents; and airborne-allergens and pathogens, such as viruses, bacteria, fungi, spores, and protozoans. Added to that are new building materials (plywood, carpet glue) and fabrics (rugs, furniture) that "offgas" toxic fumes.
What are the symptoms of indoor air quality?
Actually, the National Institute for Occupational Safety and Health ( www.cdc.gov/niosh) prefers the term "Indoor Air Quality." If 20% of the work force has symptoms -- including watering eyes; hoarseness; headaches; dry, itchy skin; dizziness; nausea; heart palpitations; miscarriages; shortness of breath; nosebleeds; chronic fatigue; mental fogginess; tremors; swelling of legs or ankles; and cancer -- the building may be labeled a "sick building." The telling factor is if the symptoms ease when workers are at home or on vacation.
How many complaints did NIOSH receive in 1980?
In 1980, NIOSH got 150 internal environmental quality complaints, 8% of total complaints. By 1990, 52% of complaints concerned sick-making work environments.
How Do Buildings Get Sick?
Historically, the 1973 oil embargo and consequent energy crisis led to an effort by builders and regulatory agencies to make buildings air tight and more energy efficient. Making buildings “tighter” meant reducing the amount of outdoor air provided for ventilation. Bitter cold and brutal heat were managed, and pleasant indoor temperatures maintained—all thanks to heating, ventilation and air conditioning (HVAC) systems.
What year was the word "sick building syndrome" first used?
The year is 1983. Microsoft releases Word, McDonald’s introduces the McNugget and Tom Cruise’s popularity rises with Risky Business. It was also the year that the World Health Organization first uses the term “sick building syndrome” to describe the adverse health effects on people due to poor indoor air quality.

Overview
Sick building syndrome (SBS) is a condition in which people in a building develop symptoms of illness or become infected with chronic disease from the building in which they work or reside. The outbreaks may or may not be a direct result of inadequate cleaning or inappropriate cleaning methods.

Signs and symptoms
Human exposure to aerosols has been documented to give rise to a variety of adverse health effects. Building occupants complain of symptoms such as sensory irritation of the eyes, nose, or throat; neurotoxic or general health problems; skin irritation; nonspecific hypersensitivity reactions; infectious diseases; and odor and taste sensations. Exposure to poor lighting conditions has led to general malaise.
Cause
ASHRAE has recognized that polluted urban air, designated within the United States Environmental Protection Agency (EPA)'s air quality ratings as unacceptable, requires the installation of treatment such as filtration for which the HVAC practitioners generally apply carbon-impregnated filters and their likes. Different toxins will aggravate the human body in different ways. Some people are more allergic to mold, while others are highly sensitive to dust. Inadequ…
Diagnosis
While sick building syndrome (SBS) encompasses a multitude of non-specific symptoms, building-related illness (BRI) comprises specific, diagnosable symptoms caused by certain agents (chemicals, bacteria, fungi, etc.). These can typically be identified, measured, and quantified. There are usually 4 causal agents in BRI; 1.) Immunologic, 2.) Infectious, 3.) toxic, and 4.) irritant. For instance, Legionnaire's disease, usually caused by Legionella pneumophila, involves a specif…
Prevention
• Regular inspections to indicate for presence of mold or other toxins
• Adequate maintenance of all building mechanical systems
• Toxin-absorbing plants, such as sansevieria
• Roof shingle non-pressure cleaning for removal of algae, mold, and Gloeocapsa magma
Management
SBS, as a non specific blanket term, does not have any specific cause or cure. Any known cure would be associated with the specific eventual disease that was cause by exposure to known contaminants. In all cases, alleviation consists of removing the affected person from the building associated. BRI, on the other hand, utilizes treatment appropriate for the contaminant identified within the building (e.g., antibiotics for Legionnaire's disease).
Epidemiology
Some studies have found that women have higher reports of SBS symptoms than men. It is not entirely clear, however, if this is due to biological, social, or occupational factors.
A 2001 study published in the Journal Indoor Air, gathered 1464 office-working participants to increase the scientific understanding of gender differences under the Sick Building Syndrome phenomenon. Using questionnaires, ergonomic investigations, building evaluations, as well as p…
History
In the late 1970s, it was noted that nonspecific symptoms were reported by tenants in newly constructed homes, offices, and nurseries. In media it was called "office illness". The term "sick building syndrome" was coined by the WHO in 1986, when they also estimated that 10–30% of newly built office buildings in the West had indoor air problems. Early Danish and British studies reported symptoms.
