Indoor Air Quality (IAQ)
Indoor Air Quality (IAQ) Assessment
In recent years, indoor air quality (IAQ) has emerged as a critical global health concern. As outdoor air emissions increasingly infiltrate buildings, they contaminate the indoor air and pose significant health risks to occupants. Building owners and managers must recognize the impact of indoor air quality on the daily lives of those within their facilities.
Continuous or even single exposures to airborne contaminants can lead to severe health issues, including respiratory problems and the spread of infectious diseases. Without regular indoor air quality assessments, these pollutants often go undetected, silently compromising the well-being of building occupants.
Ensuring clean indoor air through comprehensive assessments and proactive measures is essential for maintaining a healthy and safe environment. Prioritize indoor air quality (IAQ) to protect the health of your building’s occupants today.
Why Indoor Air Quality is so Important?
According to the Department of Occupational Safety and Health’s (DOSH) Industry Code of Practice on Indoor Air Quality 2010, building owners and managers must maintain the indoor environment within acceptable air quality standards. It is essential for building and facility managers to comply with these regulations to ensure a safe and healthy environment for all occupants.
By adhering to DOSH guidelines, building management can prevent health risks associated with poor indoor air quality and fulfill their legal responsibilities. Regular monitoring and maintenance are crucial to achieving these standards and providing a safe working environment.
Exposure to poor indoor air quality causes:
Chronic Headaches
Fatigue
Flu symptoms
Respiratory symptoms
Worsening allergies
Red eyes

You may notice some of the more common side effects of indoor air pollution, like an unpleasant odor, but many others go undetected because germs and pathogens do not show symptoms immediately which later causes greater harms to health. This is when our Indoor Air Quality Testing and Analysis will evaluate and interpret the condition of your Indoor Air Quality and finally recommend the next course of action. Our analysis/assessment and our recommendations of the indoor air and next course of action is based on Industry Code of Practice on Indoor Air Quality 2010 by the Department of Occupational Safety and Health.
How Do We Do
Frequently Asked Questions
Studies done by the U.S. Environmental Protection Agency (EPA) indicate that the indoor levels of pollutants may be 2-5 times, and occasionally more than 100 times higher than outdoor levels. These levels become a concern because it’s estimated that people spend almost 80% of their time
indoors.
Sick building syndrome (SBS) describes a situation in which building occupants experience acute health and/or comfort effects that appear to be linked to time spent in a particular building, but where no specific illness or cause can be identified.
That really depends on who you talk to. Facility managers understand that they carry some responsibility. Building occupants do not generally accept any responsibility. We however feel that everyone shares the responsibility for the indoor air quality of a building.
