It is the goal of all EATechs staff to gain as much experience and knowledge for the purpose of understand the limit and/or extent environmental factor may attribute to complaints revolving around your health, and your property (including future value(s).

What does this mean? It means that the staff of EATechs has also gained the expected knowledge to conduct reliable investigation, inspections, indoor air quality sampling, heating ventilation, & air conditioning (HV/AC) inspections, and assemble reports reflecting our findings. The CIEC holder has met the following experience and body of knowledge:

The CIEC is a third party (CESB) accredited designation.

The Council for Engineering and Scientific Specialty Boards (CESB) has accredited certification
programs in engineering and applied science since 1990.  CESB is entirely independent of industry
organizations, and exists solely to promote high standards in the certification industry.

CESB accreditation is extremely difficult to achieve. It is available only to certifying bodies who maintain rigorous standards for candidate eligibility and program operation. Accredited certifying bodies must be independent of training organizations. They must follow strict guidelines for exam development and security. They must evaluate education and field experience as well as exam performance. Such standards are the reason that CESB-accredited programs like the Certified Industrial Hygienist (CIH) are revered as marks of integrity and credibility.The IAQ Council has achieved CESB accreditation for eight of its certification programs.

CIEC Required Body of Knowledge:

The effective practice of indoor air quality investigation requires knowledge of a variety of subjects, from current standards and building codes to HVAC system design and maintenance. For certification purposes, the candidate for the CIEC™ designation must demonstrate familiarity with the basic concepts and reference materials of the industry, such as those summarized in the following list.

Hollace Bailey, Fungal Contamination: A Manual for Investigation, Remediation and Control (Jupiter, Fla: BECi, 2005)

EPA, Building Air Quality: A Guide for Building Owners and Facility Managers (Washington: EPA, 1991)

ASHRAE, Standard 55 – 2004: Thermal Environmental Conditions for Human Occupancy

ASHRAE, Standard 62.1 – 2004: Ventilation for Acceptable Indoor Air Quality

CIEC Required Skills:
A Council-certified Indoor Environmental Consultant™ (CIEC™) has demonstrated the following skills through a combination of documented experience, documented education and training and the successful completion of an examination process.

IAQ Contaminants and Health Effects
 Apply scientific knowledge of indoor environmental contaminants and general knowledge of their potential health effects to the investigation of indoor environmental quality.

The Built Environment
 Apply general knowledge of the design, construction and furnishing of the built environment to the investigation of indoor environmental quality.

 Understand common construction techniques and related technical drawings used in single family homes, multi-family residential buildings, commercial buildings and institutional facilities.

 Understand the sources, pathways and driving forces of condensation and humidity in indoor environments.

 Understand building materials and interior furniture and fixtures, their potential for off-gassing and their ability to affect indoor environmental quality.

 Apply knowledge of heating, ventilation, and air conditioning (HVAC) principles, components and standards to the investigation of indoor environmental quality problems.

 Understand the HVAC system’s role in maintaining pressurization, ventilation and temperature of indoor environments, and its effects on indoor environmental quality.

 Understand diagnostic procedures used to evaluate HVAC systems including air test and balance, air filtration and static capability.

 Apply knowledge of the basic principles of operation and limitations of instruments used to obtain objective indoor environmental quality measurements, and analyze and interpret correctly the data gathered during an environmental investigation.
Guidelines, Regulations & Standards

 Apply knowledge of occupational standards related to the maintenance and improvement of indoor environmental quality.

 Develop, manage, document and verify the correction of an indoor environmental quality problem.

 Apply current standards and guidelines of care relevant to improving indoor environmental quality, including containment, worker protection and project verification.

 Prepare all documents related to the successful completion of a project, including report of findings, project specification, documentation of practices and procedures, and verification plan.

 Conduct visual assessments and employ appropriate testing procedures to qualify and quantify indoor environmental quality conditions both before and after work.

The CIEC is Accredited by the CESB as an Engineering Level designation.

Third Party Accreditation (CESB)

The Council for Engineering and Scientific Specialty Boards (CESB) has accredited certification programs in engineering and applied science since 1990. CESB is entirely independent of industry organizations, and exists solely to promote high standards in the certification industry. Candidates for certification must pass a standardized exam based on a range of industry texts and administered independently of training organizations. These “industry certifications” are more difficult to acquire and often more expensive to maintain. Certificate holders are respected by insurance companies as experts in their field and by juries as authorities in the courtroom.
