Indoor Environmental Quality

Indoor Environmental Quality Involves More Than Just Air Quality.   

The quality of the air you breathe is important; it should be fresh, clean, free of dust, contaminants and odors - no question.  But other aspects of the indoor environment are important also.  Factors like ergonomics, sound quality, lighting, hygiene and cleanliness, thermal comfort, vibration and water quality can all have an impact on health and comfort.  

What Causes Indoor  Environmental Quality Problems?   

Through scientific research over the past 30 years,  we have learned that IEQ problems are often related to building and occupancy issues such as: 

• Energy conservation measures that produce tighter buildings from less air infiltration and reduced supply of outdoor air.  
• Increased use and complexity of building materials, equipment and furnishings that give off chemicals into the environment. 
• Deficiencies in design, operation and maintenance of ventilation systems
• Pollutants from outdoor sources
• Increased number of people working indoors and increased time at work

The Types of Problems We Solve Include Those Relating To: 

• Temperature and Comfort
• Ventilation system performance, operation, contamination
• Odors
• Dust and Particulates
• Mold and moisture
• Volatile organic chemicals 
• Allergens 
• Combustion products
• Humidity and Dryness
• Stuffiness and Air distribution
• Occupant health concerns and symptoms
• Materials, products, furnishings and equipment emissions
• Ergonomics
• Noise and lighting

Services provided:

• Review of the problem history and relevant background information
• Develop an investigation plan to address concerns
• Onsite inspection, walk-through surveys and pollutant pathways analysis
• Baseline evaluations
• Employee interviews
• Analysis of occupant health concerns
• Testing and Measurements - Carbon dioxide, carbon monoxide, temperature, humidity, dust, allergens, tobacco smoke, chemicals (pesticides, VOCs, combustion gases, others), noise, lighting, airflows, air distribution, pressure relationships, continuous monitoring and datalogging
• Proactive monitoring and inspection programs
• Ventilation system diagnostic assessment
• IAQ considerations in reoccupancy of buildings following shutdown due to the COVID pandemic

Indoor Environmental Quality Project Experience Includes:

Large-scale residential and multi-building baseline evaluations, microbial contamination, odor investigations, sick buildings and contaminant exposure concerns.  Indoor air quality investigations have been conducted in academic buildings, courthouses, correctional facilities, schools, libraries, a residential housing authority, airport, commercial high rise buildings, office buildings and residences.  

Indoor air quality problems can affect occupant health, comfort and productivity.  We partner with clients to identify and resolve issues promptly and to communicate findings and risks to those concerned.
