Indoor Air Quality

  1. 1. Indoor Air QualityIndoor Environmental Consultants (IEC) 787 568-8880
  2. 2. The NewsSeveral studies by EPA, states, andindependent scientific panels haveconsistently ranked indoor air pollution asan important environmental healthproblem.
  3. 3. The Good NewsIndoor Environmental Consultants (IEC) can helpyou in all your Indoor Air Quality (IAQ) needs.
  4. 4. Acceptable Indoor Air QualityThe American Society of Heating, Refrigerating, andAir-Conditioning Engineers (ASHRAE) definesacceptable IAQ as “air in which there are no knowncontaminants at harmful concentrations asdetermined by cognizant authorities and with whicha substantial majority (80% or more) of the peopleexposed do not express dissatisfaction.(ASHRAE Standard 62.1-2010, Ventilation forAcceptable Indoor Air Quality)
  5. 5. Why is Indoor Air Quality Important?EPA Statement:Indoor air quality is a major concern to businesses,building managers, tenants, and employees becauseit can impact the health, comfort, well being, andproductivity of building occupants.
  6. 6. Why is Indoor Air Quality Important?Most Americans spend up to 90% of their timeindoors and many spend most of their working hoursin an office environment. Studies conducted by theU.S. Environmental Protection Agency (EPA) andothers show that indoor environments sometimescan have levels of pollutants that are actually higherthan levels found outside.Pollutants in our indoor environment can increasethe risk of illness.
  7. 7. Can better air quality reduce your buildings operating costs?A proactive approach to indoor air quality (IAQ) cansave money through improved heating and coolingefficiencies; improved office environment, occupantmorale, and increased employee productivity.
  8. 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 whichcan have significant economic impacts for buildingowners and occupants.While it is hard to put firm numbers on these benefits,there is increasing evidence of measurable productivityincreases and reduced absentee rates in spaces withbetter IAQ. In considering the economics of IAQ, it isimportant to note that the salaries of building occupantsare the largest cost associated with building operation,over passing energy by a factor of 50 or even 100.
  9. 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. 10. Proactive approachA Pro-Active approach is to assess your buildingto identify factors or conditions that could negativelyimpact indoor air quality, including mold growth orwater intrusion and to conduct air sampling toassure compliance with recognized standards forIAQ.
  11. 11. Proactive approachBy taking a proactive approach, buildingmanagement can lessen the chance that problemswill occur and be ready to deal with IAQ issues whenthey do arise.
  12. 12. Our Mission IECTo help you to assure compliance with maximumindoor pollutant concentrations and to identify anyissue that can have major impact on IAQ.This is why as a joint venture we offer for your peaceof mind, the following services:
  13. 13. BASELINE IAQ TESTINGHVAC 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. 14. BASELINE lAQ TESTINGAir 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. 15. BASELINE IAQ TESTINGEnvironmental (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. 16. BASELINE lAQ TESTINGAir-O-Cell samples, in order to ascertain levels of airborne particles such as opaque particles, skin cellfragments, dust and fibers.
  17. 17. BASELINE lAQ TESTINGHVAC System Inspection:Cleaning and hygiene condition assessmentincluding the AHU’s and Ductwork.Note: Maintaining clean heating, ventilation and air-conditioning (HVAC) systems is an important part ofsustaining acceptable indoor air quality (IAQ).
  18. 18. BASELINE lAQ TESTINGHVAC System Inspection:Filtration System assessment including; filterinstallation; integrity, efficiency and replacementschedule.Drain pan operation and condition.
  19. 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. 20. HVAC System InspectionThis inspection of the AHU’s will be conductedaccording to the NADCA ACR 2006 Standard“Assessment, Cleaning and Restoration of HVACSystems” and the guidelines published in theInspection Manual of Air Conditioning Systems“Procedures for Assessing the Cleanliness ofCommercial HVAC Systems”
  21. 21. Building ChecklistUse, Occupancy, Outdoor Sources, Water Damageand Fire Damage events, Renovations, Pest Controland Cleaning Practices.Visual inspection of the plenum area to determinethe presence or absence of microbial contaminationand/or any other contaminants.
  22. 22. Building ChecklistVisual inspection of structural components todetermine the presence or absence of microbialcontamination or water damage (ceiling tiles,gypsum board, etc.).Water activity (%) sampling at hydroscopic buildingsmaterials.
  23. 23. Building ChecklistVerification of building pressure differentialassessment.Verification of building pressure differential.
  24. 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. 25. Can we help you in a Reactive approach?We can also help you pre-qualifying the remediationcontractor and to act as a project manager if yourequest so.
  26. 26. Other Services Available Renovation and Construction Impact on IAQGuidelinesAny construction or renovation activity can beconsidered a source of indoor air pollutants andpotential contributor to IAQ problems. Theseactivities have the potential to impact occupantsboth in new buildings where work is ongoing aftersome areas are occupied and in old buildings underrenovation or reconfiguration projects.
  27. 27. Renovation and Construction Impact on IAQ GuidelinesThe best time to address the effects of renovationand repair on IAQ is in the planning stage. Manymethods are available to maintain IAQ duringdemolition, construction or renovation and we canhelp you to establish the necessary guidelinesto minimize the impact of the works on theoccupied areas.
  28. 28. Consulting services for U.S. Green Building Council, LEED, Indoor Environmental Quality prerequisites and creditsOur technical consulting team providesconsultation for best practices on how toachieve your indoor environmental qualitygoals during the construction phase
  29. 29. USGBC, LEED, Indoor Environmental Quality (IEQ) prerequisites and creditsand/or our trained field staff conducts on-sitebuilding IEQ commissioning through a baseline IAQtesting after construction ends and prior tooccupancy using testing protocols consistent with theUSEPA Compendium of Methods for theDetermination of Air Pollutants in Indoor Air.
