Case Studies
Air Quality Issue in an Office Space
A building owner was concerned about the indoor air quality (IAQ) in their office after several staff members reported health issues, such as headaches, fatigue, and respiratory discomfort, which they believed were linked to poor air quality. The owner needed to determine whether the building’s air quality was the cause and ensure a safe and healthy environment for occupants.
Our SolutionIAQ Monitoring for BREEAM, WELL & LEED Certification
Building owners and developers aiming for BREEAM, WELL or LEED certification often face the challenge of demonstrating compliance with strict indoor air quality (IAQ) standards. These certifications require rigorous testing and documentation to ensure that indoor environments are healthy, sustainable, and conducive to occupant well-being. Without accurate and reliable IAQ data, achieving certification can be delayed or even denied.
How We HelpIAQ Problems in a Hospital
A hospital located next to a major road was concerned about the impact of outdoor air pollution on its indoor air quality (IAQ). With patients, staff, and visitors relying on a clean and healthy environment, the hospital needed to determine whether traffic-related pollutants, such as nitrogen dioxide (NO₂) and particulate matter (PM₂.₅), were infiltrating the building and compromising indoor air quality.
How We Can HelpNitrous Oxide (Entonox) Concerns in Hospitals
Nitrous oxide, commonly known as Entonox, is widely used in hospitals for pain relief, particularly in areas like maternity suites. However, improper ventilation or leaks can lead to the build-up of nitrous oxide in the air, posing potential long-term health risks to staff who are regularly exposed. Prolonged exposure to elevated levels of nitrous oxide can cause dizziness, nausea, and even neurological effects, making it essential to monitor and control its concentration in hospital environments.
How We Can HelpIAQ Problems in a Home
A homeowner was concerned about indoor air quality (IAQ) issues caused by emissions from a neighbor’s wood-burning stove. They suspected that smoke was leaking through the brickwork of an old shared chimney, affecting the air quality inside their home. The homeowner needed definitive proof to resolve the dispute and take appropriate remedial action.
How We Can HelpIAQ Issues in a Workplace
An employer was concerned that particle and volatile organic compound (VOC) emissions from industrial processes might be spreading to adjacent office areas, potentially affecting employee health and productivity. They needed to determine whether their existing local exhaust ventilation (LEV) systems were effectively controlling these emissions and maintaining safe air quality throughout the workplace.
How We Can HelpHave a question? Check out the FAQ
What is indoor air quality (IAQ), and why is it important?
Indoor air quality refers to the air quality within and around buildings. Poor IAQ can impact health, comfort, and well-being by exposing individuals to pollutants.
What pollutants can be found in indoor air?
Common pollutants include carbon monoxide, carbon dioxide, volatile organic compounds (VOCs), formaldehyde, airborne particles (PM2.5 & PM10), and biological contaminants like mold and bacteria.
How do you measure indoor air quality?
We use specialized monitoring equipment to measure gases, airborne particles, humidity, temperature, and ventilation rates to assess IAQ.
What are the signs of poor indoor air quality?
Symptoms include headaches, dizziness, fatigue, respiratory issues, and unpleasant odors.
Can indoor air quality affect health?
Yes, prolonged exposure to poor IAQ can lead to respiratory diseases, allergies, and long-term health effects.
How can I improve my indoor air quality?
Regular ventilation, air purifiers, reducing pollutant sources, and professional IAQ assessments can help improve air quality.
