2. The News
Several studies by EPA, states, and
independent scientific panels have
consistently ranked indoor air pollution as
an important environmental health
problem.

3. The Good News
Indoor Environmental Consultants (IEC) can help
you in all your Indoor Air Quality (IAQ) needs.

4. Acceptable Indoor Air Quality
The American Society of Heating, Refrigerating, and
Air-Conditioning Engineers (ASHRAE) defines
acceptable IAQ as “air in which there are no known
contaminants at harmful concentrations as
determined by cognizant authorities and with which
a substantial majority (80% or more) of the people
exposed do not express dissatisfaction.
(ASHRAE Standard 62.1-2010, Ventilation for
Acceptable Indoor Air Quality)

5. Why is Indoor Air Quality Important?
EPA Statement:
Indoor air quality is a major concern to businesses,
building managers, tenants, and employees because
it can impact the health, comfort, well being, and
productivity of building occupants.

6. Why is Indoor Air Quality Important?
Most Americans spend up to 90% of their time
indoors and many spend most of their working hours
in an office environment. Studies conducted by the
U.S. Environmental Protection Agency (EPA) and
others show that indoor environments sometimes
can have levels of pollutants that are actually higher
than levels found outside.
Pollutants in our indoor environment can increase
the risk of illness.

7. Can better air quality reduce your buildings
operating costs?
A proactive approach to indoor air quality (IAQ) can
save money through improved heating and cooling
efficiencies; improved office environment, occupant
morale, and increased employee productivity.

8. Can better air quality reduce your
buildings operating costs?
IAQ affects occupant health, comfort, and productivity,
and in some cases even building usability, all of which
can have significant economic impacts for building
owners and occupants.
While it is hard to put firm numbers on these benefits,
there is increasing evidence of measurable productivity
increases and reduced absentee rates in spaces with
better IAQ. In considering the economics of IAQ, it is
important to note that the salaries of building occupants
are the largest cost associated with building operation,
over passing energy by a factor of 50 or even 100.

9. Can better air quality reduce your
buildings operating costs?
To think about:
If you are a property manager, improved IAQ will
also help make your building more
marketable to prospective tenants.

10. Proactive approach
A Pro-Active approach is to assess your building
to identify factors or conditions that could negatively
impact indoor air quality, including mold growth or
water intrusion and to conduct air sampling to
assure compliance with recognized standards for
IAQ.

11. Proactive approach
By taking a proactive approach, building
management can lessen the chance that problems
will occur and be ready to deal with IAQ issues when
they do arise.

12. Our Mission IEC
To help you to assure compliance with maximum
indoor pollutant concentrations and to identify any
issue that can have major impact on IAQ.
This is why as a joint venture we offer for your peace
of mind, the following services:

13. BASELINE IAQ TESTING
HVAC System Verification:
To assure compliance with recognized standards for
indoor air quality including ASHRAE Standard 62-
2010 or latest version, verify the performance of each
HVAC system including space temperature and
space humidity uniformity and outside air quantity.

14. BASELINE lAQ TESTING
Air Sampling:
Collect air samples during normal business hours,
with building operating at normal HVAC rates for:
- Sample and record outside air levels of
formaldehyde and TVOC contaminants at outside air
intake simultaneously with indoor tests to establish
basis of comparison for these contaminant levels.
Indoor testing will be done in the breathing zone;
between 3' and 6' from the floor.

15. BASELINE IAQ TESTING
Environmental (Indoor) Monitoring for:
- Particles (PM10, PM2.5) - Total VOCs
-Bioaerosols air (indoor vs. outdoor comparison)
-Bioaerosols surfaces (visible growth)
-Carbon Dioxide - Carbon Monoxide - Ozone
- Nitrogen dioxide - Ammonia -Hydrogen sulfide

16. BASELINE lAQ TESTING
Air-O-Cell samples, in order to ascertain levels of air
borne particles such as opaque particles, skin cell
fragments, dust and fibers.

17. BASELINE lAQ TESTING
HVAC System Inspection:
Cleaning and hygiene condition assessment
including the AHU’s and Ductwork.
Note: Maintaining clean heating, ventilation and air-
conditioning (HVAC) systems is an important part of
sustaining acceptable indoor air quality (IAQ).

18. BASELINE lAQ TESTING
HVAC System Inspection:
Filtration System assessment including; filter
installation; integrity, efficiency and replacement
schedule.
Drain pan operation and condition.

19. BASELINE IAQ TESTING
 HVAC System Inspection:
 Identification of visible contamination sources;
internal insulation, fan, coil and other internal
components
 Condition and physical integrity of the housing,
components and surfaces.
 Fresh air intake location.

20. HVAC System Inspection
This inspection of the AHU’s will be conducted
according to the NADCA ACR 2006 Standard
“Assessment, Cleaning and Restoration of HVAC
Systems” and the guidelines published in the
Inspection Manual of Air Conditioning Systems
“Procedures for Assessing the Cleanliness of
Commercial HVAC Systems”

21. Building Checklist
Use, Occupancy, Outdoor Sources, Water Damage
and Fire Damage events, Renovations, Pest Control
and Cleaning Practices.
Visual inspection of the plenum area to determine
the presence or absence of microbial contamination
and/or any other contaminants.

22. Building Checklist
Visual inspection of structural components to
determine the presence or absence of microbial
contamination or water damage (ceiling tiles,
gypsum board, etc.).
Water activity (%) sampling at hydroscopic buildings
materials.

23. Building Checklist
Verification of building pressure differential
assessment.
Verification of building pressure differential.

24. Can we help you in a Reactive approach?
Yes
A reactive approach is a situation in which you
attempt to identify and solve indoor air quality
problems which are occurring.
 We can help you to identify the problem, its cause
and by designing the mitigation protocol. It is
important to understand that attempting to correct
IAQ problems without understanding the cause of
those problems can be both ineffective and
expensive.

25. Can we help you in a Reactive approach?
We can also help you pre-qualifying the remediation
contractor and to act as a project manager if you
request so.

26. Other Services Available
Renovation and Construction Impact on IAQ
Guidelines
Any construction or renovation activity can be
considered a source of indoor air pollutants and
potential contributor to IAQ problems. These
activities have the potential to impact occupants
both in new buildings where work is ongoing after
some areas are occupied and in old buildings under
renovation or reconfiguration projects.

27. Renovation and Construction Impact on
IAQ Guidelines
The best time to address the effects of renovation
and repair on IAQ is in the planning stage. Many
methods are available to maintain IAQ during
demolition, construction or renovation and we can
help you to establish the necessary guidelines
to minimize the impact of the works on the
occupied areas.
