Allergy Sufferers Need Great IAQ

Posted June 06, 2010 8:18 AM

If you suffer from seasonal allergies, you might seek a nice, climate controlled and filtered air conditioned space in which to live and work. How important is properly maintained IAQ to allergy sufferers and what role does HVAC play? According to Dr. Beth Corn, Assistant Professor of Medicine at the Mount Sinai School of Medicine and Past President of the New York Allergy and Asthma Society, "Some patients think they can stay indoors, but you should be just as concerned about indoor air quality." As an HVAC design or contracting professional, what advice do you have to keep commercial buildings as allergen free as possible while maintaining superior IAQ? What happens when indoor air contains as many allergens as out?

The preceding article is a "sneak peek" from HVAC, a newsletter from GlobalSpec. To stay up-to-date and informed on industry trends, products, and technologies, subscribe to HVAC today.

Don't you just love it when someone save themselves a little time and dumps in an acronym, and sixty two other people have to spend time to derive it or research its meaning?

It was confusing, although its meaning was mentioned in a later sentence.

IAQ means Indoor Air Quality. A healthy solution should be able to be achieved if good standards of design, commissioning, operation and maintenance are followed. The most obvious steps in the prevention of indoor-air pollution are to ensure that (i) the design and the operation of the building is according to the state of the art in relation to building application and conducted activities, (ii) building performance is according to the specifications in relation to pollutant concentrations and operating parameters, and (iii) steps i and ii are routinely monitored. Even if the aforementioned preventive steps are taken, there is a potential for indoor-air problems to still occur, due to the various reasons outlined in this paper. In such cases, it is important for HVAC engineers, hospital facility managers and hospital infection control officers to be aware that there could be still problems, and not to ignore warnings or indications of problems, particularly if related to symptoms of human ill health, and be innovative and open to novel methods of investigation. Maintaining clean heating, ventilation and air-conditioning (HVAC) systems is an important part of sustaining acceptable indoor air quality (IAQ).

Based on the visual inspection of ducts at various sites it has been observed that very few HVAC systems are "spotlessly" clean. Therefore it is suggested to make a statuary requirement to clean the ducts at constant interval as per the international standards in all health care units. Regular cleaning of cooling coils of the air handling units is strongly recommended to minimize the air pollution in a.c systems. Together identify report, rectify inferior conditions or potential problem areas and take necessary steps as not to re occur the same type of problem again elsewhere in the health care facility.

Ultra high Absolute HEPA (High Efficiency Particulate Air) filter with efficiency in excess of

99% when measured by using DOP (Di-Octyle Phthalate) method. Is good solution for indoor air quality.

Some HVAC contractors will say that when your filters get dirty they actually are then able to catch more dirt and therefore filter the air better then if they were clean. Obviously in a hospital you don't want to cut corners, but at your home i don't think it hurts to let those filters collect some dust, just not too much.
