Indoor Air Quality

Product Knowledge

It’s been a problem for tens of thousands of years. Maybe it’s time to fix it. From the Padahlin caves in Myan-mar to New Mexico’s Tsankawi Mesa pueblos, ancient human dwellings are stained with soot from cooking fires. Paleolithic people had problems with air quality indoors before they even had doors.

Fast forward to the twenty-first century. We’ve quit barbecuing cave bear in the living room, but indoor air quality (IAQ) is still an issue. Problems appeared to increase after the �970s energy crisis, when architects and owners redesigned HVAC systems, adjusted operations and sealed buildings more effec-tively in an effort to conserve energy.

The term “sick building syndrome” (SBS) describes situations when building occu-pants experience health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be found. Professionals use the term “build-ing related illness” (BRI) when symptoms of diagnosable illness can be attributed directly to airborne building contaminants.

The effectsHealth effects from indoor air pollutants may be experienced soon after exposure or, possi-bly, years later.

Immediate effects include irritation of the eyes, nose, and throat, headaches, dizzi-ness, and fatigue. Such immediate effects are usually short-term and treatable. Some-times the treatment is simply eliminating the person’s exposure to the source of the pollu-tion, if it can be identified.

Certain immediate effects are similar to those from colds or other viral diseases, so it’s often difficult to determine if the symptoms are a result of exposure to indoor air pollution. For this reason, it’s important to pay attention to the time and place symptoms occur. If the symptoms fade or go away when a person is away from home, for example, an effort should be made to identify home indoor air sources that may be possible causes. Some effects

may be made worse by an inadequate supply of outdoor air or from the heating, cooling, or humidity conditions prevalent in the home.

What do we mean by indoor air quality?Humidity and temperature are important comfort factors, and failure to manage them can create other problems — allowing the growth of mold, or turning chillers into biol-ogy experiments.

Common indoor air pollutants include tobacco smoke; biological agents like animal dander, bacteria and mold; airborne particu-lates; volatile organic compounds like glue, solvents, cleaning agents; carbon dioxide and carbon monoxide; and pesticides.

Many of these materials are found in minute amounts in most indoor environments. When concentrations or combinations of pollutants rise excessively, however, IAQ deteriorates. IAQ problems can result from a host of factors.

What Causes Indoor Air Problems?Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems in homes. Inad-equate ventilation can increase indoor pollut-ant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the home. High temperature and humid-ity levels can also increase concentrations of some pollutants.

Indoor Air Quality

Product Knowledge

There are many sources of indoor air pollu-tion in any home. These include combustion sources such as oil, gas, kerosene, coal, wood, and tobacco products; building materials and furnishings as diverse as deteriorated, asbestos-containing insulation, wet or damp carpet, and cabinetry or furniture made of certain pressed wood products; products for household cleaning and maintenance, personal care, or hobbies; central heating and cooling systems and humidification devices; and outdoor sources such as radon, pesticides, and outdoor air pollution.

The relative importance of any single source depends on how much of a given pollutant it emits and how hazardous those emissions are. In some cases, factors such as how old the source is and whether it is properly main-tained are significant. For example, an improperly adjusted gas stove can emit significantly more carbon monoxide than one that is properly adjusted.

Some sources, such as building materials, furnishings, and household products like air fresheners, release pollutants more or less continuously. Other sources, related to activities carried out in the home, release pollutants intermittently. These include smoking, the use of unvented or malfunctioning stoves, furnaces, or space heaters, the use of solvents in cleaning and hobby activities, the use of paint strippers in redecorating activities, and the use of cleaning products and pesticides in house-keeping. High pollutant concentra-tions can remain in the air for long periods after some of these activities.

Amount of VentilationIf too little outdoor air enters a home, pollutants can accumulate to levels that can pose health and comfort problems. Unless they are built with special mechanical means of ventilation, homes that are designed and constructed to minimize the amount of outdoor air that can “leak” into and out of the home may have higher pollutant levels than other homes. However, because some weather conditions can drastically reduce the amount of outdoor air that enters a home, pollutants can build up even in homes that are normally considered “leaky”.

How Does Outdoor Air Enter a House?Outdoor air enters and leaves a house by:

infiltration, natural ventilation, and mechani-cal ventilation. In a process known as infiltra-tion, outdoor air flows into the house through openings, joints, and cracks in walls, floors, and ceilings, and around windows and doors. In natural ventilation, air moves through opened windows and doors. Air movement associated with infiltration and natural venti-lation is caused by air temperature differences between indoors and outdoors and by wind. Finally, there are a number of mechanical ventilation devices, from outdoor-vented fans that intermittently remove air from a single room, such as bathrooms and kitchen, to air handling systems that use fans and duct

work to continuously remove indoor air and distribute filtered and conditioned outdoor air to strategic points throughout the house. The rate at which outdoor air replaces indoor air is described as the air exchange rate. When there is little infiltration, natural ventilation, or mechanical ventilation, the air exchange rate is low and pollutant levels can increase.

Keys to IAQ: design, operation and maintenance of HVAC systemsPoor design of buildings and HVAC systems is one cause. An air intake located above a load-ing dock, for instance, could draw in vehicle exhaust and distribute carbon monoxide, oxides of nitrogen and diesel soot to every

cubicle. Systems without sufficient fresh air exchange can allow CO� and volatile organic compounds to build up. The wrong construc-tion materials can emit excessive chemicals from glue and paint.

Another big factor is system operation. Air pressure, temperature, humidity and operat-ing cycles must all be properly adjusted to balance operating efficiency with the comfort of building occupants. Leaving systems off until occupants arrive in the morning might save money, for instance, but allow pollutants to build up in the air. Better to start systems early and condition the air before people show up. Leaving doors or windows open between office space and a shop floor could virtually guarantee IAQ problems.

The third big IAQ determinant is system maintenance. Even the best building and HVAC design won’t deliver the results it should if electrical systems or vents fail, filters aren’t frequently changed or correctly installed, fan and compressor motors malfunc-tion or controls fail to perform.

Evaluating relative humidity: Key factors and measurementsUnderstanding the relationship between dry bulb temperature, wet bulb temperature, relative humidity, and dew point temperature is essential in all facets of air conditioning.

The good news, strangely enough, is that poor humidity and temperature levels are likely to cause occupant discomfort.

Dry bulb temperature: Air temperature determined by an ordinary thermometer.

Wet bulb temperature: Represents the cooling effect of evaporating water, the temperature air will cool to when water evaporates into unsaturated air.

Relative humidity: Ratio of water vapor pressure (amount currently in the air) to the saturation vapor pressure (the amount the air can hold) at a given air temperature.

Dewpoint temperature: The temperature under which water will condense out of the air.

FungusConditions for fungal growth include spores settling on a surface, a micro-environment ensuring oxygen, optimal temperatures, nutri-ents, and moisture. Four of these conditions are found in nearly every environment. The most controllable variant is moisture.

Relative humidity above 60% can support

fungal growth on hygroscopic surfaces, ones that readily take up and retain mois-ture. Nearly all surfaces are, or can become, hygroscopic and include painted surfaces, gypsum dry wall, carpets, wall coverings, and masonry products. Even glass with a dirt film and dust on it can support fungal growth.

Masonry products such as brick, cinder block and concrete are excellent sorbents and can absorb vast quantities of moisture and become an inviting breeding environment for molds.

CondensationConditions that allow condensation to form on surfaces are more obvious, so action can be taken immediately. When a surface tempera-ture is at or below the dew point temperature, condensation will form. Likely places for this to occur are on basement surfaces, crawlspace surfaces, cold water pipes, on air handling equipment and duct work, and unseen within envelope walls.

In cooling systems, relative humidity in supply ducts can be 95 % or higher, and evaporators and condensate pans will be wet. So, since moisture control is not feasible, control of airborne spores and food (dust and airborne particles) with good, tight fitting filtration systems in place is essential to control fungus growth.

HVAC/Indoor Air Quality Tools

Product Knowledge

Dirty coils, fans, and filters increase static pressure by reducing airflow, causing HVAC equipment to work harder to meet occupant loads thus increasing energy costs. With HVAC energy costs often comprising over 50% of the total energy bill, tighter monitoring and control of HVAC airflow can have a direct impact on the bottom line.

How HVAC airflow impacts operating costs• In a study� on coil cleaning and energy savings in a New York City high rise, pres-sure monitoring and visual inspection led to restoration of the coils and components. The restoration resulted in a �4% decrease in pressure drop across the coils, a 25% increase in the coil’s thermal efficiency, and energy savings of up to $40,000 in the first year.• EPA studies2 show that a �5 cfm airflow differential can impact annual HVAC energy costs by up to 8 % depending upon the HVAC system and variations in climate.

Air quality test instruments must deliver accurate and verifiable performance, both to ensure precise and reliable air quality diagno-sis, and to provide credible answers if results or procedures are challenged. The air qual-ity professional’s reputation depends on the quality and performance of the test tools in� Baker, Robert G.; Montgomery, Ross D. “Coil Cleaning and its Resultant Energy Savings and Maintenance Enhancements.” Indoor Air Quality Conference Proceedings, 2006:22-27.2 “Energy Cost and IAQ Performance of Ventilation Systems and Controls, Project Report #4.” United States Environmental Protection Agency, January 2000:�0.

Fluke 971 Temperature Humidity MeterTemperature and humidity are two impor-tant factors in maintaining optimal comfort levels and good indoor air quality. Quickly and conveniently take accurate humidity and temperature readings with the Fluke 97�, an instrument that will prove invaluable for facility maintenance and utility technicians, HVAC-service contractors, and specialists who assess indoor air quality (IAQ). Lightweight and easy to hold, the Fluke 97� is the perfect tool for monitoring problem areas. With a rugged holster and twist-open protective sensor cover, the Fluke 97� is built to perform and made to last. • Backlit dual display of humidity and

temperature, measures dew point and wet bulb temperatures

• Quick-response capacitance sensor with twist-open protective cover

• Compact and lightweight at �88 g (6.6 oz)• Temperature range from -20 °C to 60 °C (-4 °F

to �40 °F)• Relative humidity from 5% to 95%

Duct temperaturesUse the Fluke 97� and an infrared thermome-ter to monitor duct temperatures at the regis-ter. Easily calculate dewpoint with the Fluke 97�, then compare it to register temperatures to see if they fall below the dewpoint. Use an infrared thermometer in this application as a

general indicator only. Many factors come into play when taking IR measurments, such as emissivity and spot-to-distance ratio. Lower temperatures can lead to condensation form-ing on ductwork. If uninsulated, moisture can fall onto ceiling materials and cause potential mold issues and water damage.

Airborne particle detectionOver the past several years, indoor air quality (IAQ) has been a much debated and publicizedtopic, especially as it concerns public health. The EPA estimates that we spend approxi-mately 90% of our time indoors, and further studies indicate that indoor air in some commercial settings is up to five times morepolluted than outdoor air. Airborne particu-lates come in a variety of forms ranging fromanimal dander, plant pollen, and airborne bacteria, to fiberglass, asbestos, and combus-tion particles. Motionless, human beings alone shed up to 500,000 particles (0.�μm) per minute. When active, this level can reach up to 45,000,000 particles per minute. Humidity and temperature play a significant role in the generation rate of these pollutants. To properly identify and troubleshoot IAQ problems, the technician needs a tool that not only reads particle concentrations, but also provides insight into the environment that causes pollutants to grow.

Why particle counts matterDifferent locations have varying levels of acceptable particulate concentrations, driven primarily by health and comfort concerns(i.e. homes, offices, paint booths) or contami-nation (i.e. hospitals, food and beverage plants, cleanrooms). Excessive levels canresult in medical conditions such as Sick Building Syndrome, lower productivity, contaminated product, or all of the above.

Maintaining acceptable air quality levels may not only lower the costs associated with downtime, but also reduce or remove costs associated with expensive fixes in the future. The first step in establishing an IAQ mainte-nance program is to determine if a problem currently exists.

Fluke 983 Particle CounterThis tool is a portable solution for determining airborne particle concentra-tions. Use the Fluke 98� to immediately respond to occupant complaints, or as part of a comprehensive preventive maintenance program.

Every year, over 200 people in the United States die from CO produced by fuel-burning appliances (furnaces, ranges, water heaters, room heaters). Others die from CO produced while burning charcoal inside a home, garage, vehicle or tent. Still others die from CO produced by cars left running in attached garages. Several thousand people go to hospital emergency rooms for treatment for CO poisoning.

What is carbon monoxide (CO)?Carbon monoxide (CO) is a colorless, odorless, poisonous gas with potentially serious healthconsequences given adequate exposure.CO levels Exposure symptoms

Why true-rms matters for HVAC techniciansNon-linear loads need a true-rms test tool for accurate readings For today’s HVAC technician, troubleshooting electrical problems is becom-ing more difficult without the use of true-rms test tools. This is due in part to the prolifera-tion of new solid state adjustable speed motor drives and heating controls containing power semiconductors or rectifiers. These loads are referred to as “non-linear.” Non-linear loads draw current in short pulses rather than the smooth sine wave drawn by a linear load such as an induction motor. The current wave shape can have a drastic effect on a test tool reading.
