Reular HVAC Tech';s Will have to Learn IAQ- Non-Contaminanted Indoor Air


     ATLANTA –Now, finally the regular HVAC techs are going to have to learn, study, and understand mold, bacteria, off-gassing, and all the contaminants that are created in the HVAC systems (The Environmental side of the HVAC). ASHRAE- the head HVAC Organization over the HVAC Industry and the Indoor Air Quality Association (IAQA) have agreedin principle to join forces, combining resources to improve indoor air quality in the builtenvironment.Pending a three to six-month period of due diligence, IAQA will become a part of theASHRAE organization while maintaining its own brand and Board of Directors. IAQA will operateindependently within ASHRAE’s organizational structure. Plans call for IAQA headquarters to relocate fromRockville, Md., to Atlanta, Ga., home of ASHRAE’s international headquarters. The agreement wasreached between the leadership of both associations and confirmed at ASHRAE’s 2014 Annual Conferencethat concluded earlier this month in Seattle,Wash.“This merger is beneficial to both ASHRAE and IAQA in that it strengthens the programs and servicesof both organizations,” Tom Phoenix, ASHRAE president, said. “The work of IAQA complements the workof ASHRAE in its standards, research, publications and educational offerings. We now combineour resources to ensure the industry receives the best indoor air quality technical guidance andeducational programs possible, which means improved indoor air quality for the world aroundus.”
Among ASHRAE’s major indoor air quality offerings are Standard 62.1, Ventilation for AcceptableIndoor Air Quality, and Standard 62.2, Ventilation and Acceptable Indoor Air Quality in Low-RiseResidential Buildings, and publications such as the Indoor Air Quality Guide: Best Practices for Design,Construction and Commissioning.

ASHRAE also recently announced the formation of the IndoorEnvironmental Quality Global Alliance, which included IAQA as a charter member. ASHRAE also has a strongresearchprogram related to indoor air quality with 10 current projects totaling $2.8 million, representing23 percent of ASHRAE’s researchbudget.
   
    “This merger allows IAQA to maintain its own brand while also providingits members with enhanced benefits and services,” Kent Rawhouser, president of IAQA, said. “Ourstrong history of programs and products is expected to not only continue, but to grow as the merger allowsusto take advantage of the resources and programs overseen by ASHRAE. Members of IAQA andASHRAE will work collaboratively to strengthen indoor air quality programs for the industry, andmostimportantly, for the people who occupy homes and buildings around theworld.”IAQA provides continuing education, conferences and expositions, certification programs,monthly webinars, technical publications and funds indoor air quality related research. IAQA subsidiary,Indoor Environmental Standards Organization (IESO), is an American National Standards Institute(ANSI) accredited standards developing organization focused on indoor air quality assessment,remediation and management of indoorenvironments.

ASHRAE and IAQA programs will be aligned to create high-impact resources for buildingprofessionals around theglobe.“Indoor air quality is vitally important to the health and welfare of people worldwide,” Phoenix said.“Air quality systems must work harmoniously with other systems in homes and buildings to ensure ahealthy and sustainable builtenvironment.”The Indoor Air Quality Association (IAQA) is a nonprofit organization dedicated to bringingpractitioners together to prevent and solve indoor environmental problems for the benefit of customers andthe public. IAQA was established in 1995 and is the nation’s largest indoor air quality trade associationwith over 2,600 members and more than 20 local chapters across the United States and Canada.Moreinformation is available at IAGA.org and atIESO.org.ASHRAE, founded in 1894, is a global society advancing human well-being throughsustainable technologyforthebuiltenvironment.TheSocietyanditsmorethan50,000membersworldwidefocusonbuilding systems, energy efficiency, indoor air quality, refrigeration and sustainability. Throughresearch, standards writing, publishing, certification and continuing education, ASHRAE shapes tomorrow’sbuilt environment today. More information can be found atwww.ashrae.org/news.

1.    What's all the fuss about "indoor" airpollution?    I always thought "outdoor" air pollution wasthe mainproblem?Scientific evidence indicates the air within homes and other buildings can be two to five timesmore polluted than the outdoor air, and in some cases 1,000 times more polluted. Today people arespending nearly90%oftheirtimeindoors,agreatincreaseasopposedto twentyyearsago.Thus,the"dose"(i.e. the concentration of pollutants multiplied by the time in that environment) is typically greaterindoors than outdoors. This results in a greater health risk due to exposure to air pollution indoorsthan outdoors.
2.    Are some individuals at greater risk to indoor air pollution thanothers?Yes, individuals who spend the longest periods of time indoors are often those most susceptible tothe adverse effects of indoor air pollution. Such groups include babies, the elderly, the infirm orbedridden, and those with chronic illnesses, such as respiratory or cardiovasculardisease.Top ofPage
3.    What causes indoor air qualityproblems?Two mainitems:1.  Pollutant sources: building materials and furnishings; biologicals; products for janitorial cleaning, personal care, or activities used in offices; no IAQA maintenance of central heating and cooling systems and humidification devices and older duct work and improper return plenums;pesticides; past roof and plumbing leaks or other types of water intrusion, high condensation, and dew points.
2.   Poor ventilation: If too little outdoor air enters a building, pollutants can accumulate to levels that can pose health and discomfort problems. Indoor air quality began to decline in the 1970's after the "energy crisis" prompted the building of "tight" houses and office buildings. Spaces around doors and windows where outside air might previously have leaked through are now often sealed by caulking and weather- stripping. The introduction of fresh "makeup" air through air handling systems many times is reduced or even eliminated to save the cost of the energy to heat or cool this fresh air. Indoor air pollutants cannot easily escape these tightly constructed buildings.
4.    How does indoor air pollution affect yourhealth?Health effects can include irritation of the eyes, nose, and throat, headaches, dizziness, fatigue,and allergy-type symptoms. Usually these symptoms are short-term, and disappear when the person isaway from the source. More serious symptoms such as asthma, hypersensitivity pneumonitis, andhumidifier fever can also affect some individuals after exposure to certain indoor air pollutants. There isa tremendous amount of variation in the sensitivity among individuals to indoor air pollutants.Some people may never experience any symptoms while others may truly suffer. Because manysymptoms may be difficult to distinguish from viruses, or allergies; care mustbe taken to determine if symptoms are worse while in a particular building versus outside, or whetherthey dissipate when a person is away for severaldays.Top of Page
5.  What are some of the major indoor air pollutants that might be found in a home or office building?Typical pollutantsinclude:

Biologicals: Bacteria, mold and mildew, viruses, animal dander, pollen, dust mites. These are morelikely to be a problem in buildings with high humidity, or water-damage and non-maintained HVAC Systems.

Past building design issues, vapor barriers, condensation issues, unbalanced air-flow patterns, and design.

Sewer gases: from blocked traps, dry cut off traps, changes in remodeling and plumbing, non-working vent pipes for methane and other sewer gases in older buildings.

Carbon Monoxide: From unvented gas heaters; leaking chimneys or furnaces; gas stoves;automobile exhaust. Low levels can cause headaches, flu-like symptoms. High levels can befatal.

Organic Gases: From janitorial and construction products including: paints, paint strippers, and other solvents;wood preservatives; aerosol sprays; cleansers and disinfectants; moth repellents and air fresheners;stored fuels and automotive products; hobby supplies; dry-cleanedclothing.

Formaldehyde: Usually from pressed wood products (hardwood plywood paneling, particleboard, fiberboard) and furniture made with pressed wood products; or urea-formaldehyde foam insulation.
