Healthy Building Services
Indoor air quality (IAQ) related illnesses lower productivity and increase absenteeism for employees, and create economic and legal implications for building management and owners. The costs associated with IAQ problems are indisputable but are often extremely broad with the total cost to a particular facility being difficult to quantify. From an energy cost vs. worker productivity prospective, the benefit for providing comfortable work environments is clear. With the estimated energy cost to operate the building of $2 – $8/square foot/year and a worker salary cost of up to $300/square foot/year it is obvious that worker productivity is the dominant economic factor. It is estimated that a 1% increase in productivity in an average office building can justify doubling the maintenance and energy budget.
Thus, it is important for new buildings to be designed and constructed, and existing buildings be operated and maintained, to provide good IAQ and comfortable work environments for the health and productivity of occupants. As leaders in promoting the Best Practices for the IAQ field, and as members and advisors to the U.S. Green Building Council (USGBC), Leadership in Energy and Environmental Design (LEED) program, the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE), the Sheet Metal and Air Conditioning Contractors National Association (SMACNA), the American Industrial Hygiene Association (AIHA), and the Cal-OSHA Indoor Air Quality Advisory Committee, IEE is excellently positioned to assist clients with their indoor environmental quality (IEQ) project needs.
IEE provides consultation and testing services for IEQ parameters in newly constructed buildings and existing building renovations, and design of IAQ management programs, using the EPA document Building Air Quality: A Guide for Building Owners and Facility Managers, tailored specifically to existing facility operations that facility management staff can use to respond to occupant IAQ concerns and maintain good indoor air quality in their buildings.

Consulting services for a better indoor environment
IEE has performed over 4,300 building investigations and research studies throughout the United States. IEE is known for their thorough and comprehensive diagnostic methods and protocols that are tailored to fit the requirements of the specific needs of each project.
Our diagnostic services include:
Proactive IAQ CheckUps™ to help clients maintain comfortable work environments and identify indoor air quality (IAQ) problems early, thus minimizing occupant complaints.
Reactive Inspections in response to occupant concerns regarding a potential existing IAQ problem.
Forensic Investigations to determine and document building material and system failure mechanisms leading to property damage or personal injury.
Our team leaders are engineers and industrial hygienists and have extensive experience evaluating building environments and ventilation systems for investigations and research studies. IEE puts to use our experience to develop an understanding of the conditions impacting our site investigations, and provide our conclusions regarding the quality of the indoor air, with respect to appropriate guidelines, and outline mitigative actions to improve the indoor air quality where required.

IEE has both the analytical and ventilation laboratories to accommodate all the needs of indoor air quality (IAQ) investigations and research.
Our analytical laboratories utilize contaminant sampling and analytical techniques developed by agencies such as EPA, OSHA and NIOSH and are fully accredited (including AIHA EMLAP certification for mold analyses).
Our full-service ventilation laboratory has customized testing stations for evaluating the performance of:
Air cleaning and filtration devices
Building material and equipment emission rates and
Ventilation air distribution equipment.
For contaminant air sampling to have value it is essential that the laboratory analyses achieve detection limits for the target contaminant well below the concentration where symptoms or irritancy may occur. The detection limits required for non-industrial environmental inspections in residences, schools, hospitals, and offices are often many times below those provided by laboratories which focus more on industrial environments. IEE has developed specialized sampling and laboratory analytical techniques to meet the low detection limits desired in non-industrial indoor environmental investigations.

Paints, strippers, cleaners, and adhesives often contain toxic chemicals that when used can result in exposures that cause acute adverse health effects, including death. Manufacturers can and should provide users with how much ventilation (cfm) is adequate.
Laminate flooring from Lumber Liquidators has been found to emit large quantities of formaldehyde. How to test the air in your home and emissions from this flooring.
E-cigarettes are marketed as only producing harmless water vapor. However published literature shows that e-cigarettes contain many chemicals, including some that are carcinogenic.
