Sick Building Syndrome (SBS)*
* from US EPA website
According to US Environmental Protection Agency (EPA), the term "sick building syndrome" (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. The complaints may be localized in a particular room or zone, or may be widespread throughout the building. In contrast, the term "building related illness" (BRI) is used when symptoms of diagnosable illness are identified and can be attributed directly to airborne building contaminants.

Indicators of SBS include:
  • Building occupants complain of symptoms associated with acute discomfort, e.g., headache; eye, nose, or throat irritation; dry cough; dry or itchy skin; dizziness and nausea; difficulty in concentrating; fatigue; and sensitivity to odors.
  • The cause of the symptoms is not known.
  • Most of the complainants report relief soon after leaving the building.
Building Related Illness (BRI)**

Indicators of BRI include:
  • Building occupants complain of symptoms such as cough; chest tightness; fever, chills; and muscle aches.
  • The symptoms can be clinically defined and have clearly identifiable causes.
  • Complainants may require prolonged recovery times after leaving the building.

It is important to note that complaints may result from other causes. These may include an illness contracted outside the building, acute sensitivity (e.g., allergies), job related stress or dissatisfaction, and other psychosocial factors. Nevertheless, studies show that symptoms may be caused or exacerbated by indoor air quality problems.

Cleaning Equipment
  • We use high-tech robotic equipment to clean air-cond ducts.
  • The robot pre-inspects the existing “BEFORE” condition of the air-cond ducts with a video camera on-line real-time.
  • After cleaning the air-cond ducts, the robot’s camera provides a clear video of the “AFTER” condition.
