A conflict of interest is defined as a situation that has the potential to affect the impartiality of a person. This most commonly occurs in a business setting when an individual is involved in multiple interests, one or more of which has the potential to corrupt the motivation for performance in the other.
You have heard the old parables of the fox guarding the hen house or the wolf watching the sheep. The basic lesson in both is "Don't assign a job to someone who will then be in a position to exploit it for his own ends”.
There are regulations in place throughout the lead and asbestos industries to address the potential conflict of interest associated with confirming the presence of these contaminants, and then being in charge of the proper removal and disposal of them.
However, a review of mold remediation companies on any search engine or in the yellow pages shows that many of them also perform mold assessments or mold testing. Is this a conflict of interest? It would seem that at least two states think so.
Currently, Texas and Florida both require licensing throughout the mold industry. The legislation in both TX and FL clearly states that “A licensee shall not perform both mold assessment and mold remediation on the same project, or have an ownership interest in an entity that performs mold assessment services and mold remediation services on the same project.”
An Orlando FL contractor was recently arrested and now faces charges of grand theft and insurance fraud for collecting samples that were never analyzed. In addition, he provided fake lab data to support the need for extensive mold remediation - which he then also performed.
Another popular scam is to offer FREE mold inspections and sampling. Done properly, mold assessment and testing requires an investment of time, equipment, testing media and professional knowledge.
The only way a company can afford to continue to offer this assessment and testing service for free is to make a larger profit from remediating any mold problems that are found.
In no way does Air Matters LLC feel that these two examples are the norm. Many mold remediation companies are owned by hard working, ethical people who are hoping to keep some services in house to increase their profit margin and streamline the project.
However, more and more consumers are questioning the potential for conflict of interest, leading many remediation contractors to partner with third party providers.

How Does Your Home "Stack" Up?
There is constant air movement through your home. There are generally three types of forces that move air through a house: HVAC equipment, wind, and the "stack effect".
The stack effect is when warm air moves upwards in a house. Since we can't create a vacuum in our homes, new air has to come into the home to replace the air that has escaped to normalize the pressure.
Although the stack effect occurs in both the summer and the winter, the effect is usually greater in the winter due to the temperature differential. In the winter, cracks and openings throughout the building shell allow the pressure difference between indoor and outdoor spaces to drive air out of the top floor and to suck air in through the first floor.
In the summer, when indoor air is cooled, the reverse occurs; however, because the temperature difference between inside and outside typically isn't as great as it is in winter, the stack effect isn't as great either.
Whatever the season, the best way to remedy the stack effect in most houses is by minimizing gaps between indoor and outdoor spaces. Think about the places where new air is able to enter the house.
According to the US Department of Energy, the following areas are responsible for a large majority of air leakage that occurs in the average American home:
Ceiling, Walls and Floors – 31%
Ducts – 15%
Fireplace – 14%
Plumbing Penetrations – 13%
Doors – 11%
Windows – 10%
Fans and Vents – 4%
Electrical Outlets – 2%
These figures provide you with the most important areas to target for air sealing. However, a home energy audit will pinpoint the exact locations of air loss and assess your entire home’s energy consumption and waste, and recommend ways to improve your home’s energy efficiency.

I’ve done a whole lot of research on sealed crawlspaces the past few weeks. I have read everything from product literature provided by contractors who install the systems, to building science articles, to ASHRAE standards and studies. Here are a few of the highlights of what I have learned:
What is a Sealed Crawlspace?
A sealed crawlspace is also referred to as closed, conditioned, or semi-conditioned. The basic design has no vents, insulated foundation walls, a heavy plastic and/or concrete liner on the floor, and an insulated and weather-stripped access door.
A small amount of conditioned air is delivered to the crawlspace area from the HVAC system creating positive pressure in the crawlspace. The positive pressure prevents air from the crawlspace being drawn into the duct work and delivered to the living space. Crawlspace air remains in the crawl not in the living areas.
What are Some of the Benefits Claimed?
Sealed crawl space systems are said to reduce or eliminate many common problems, such as:
• Mold or moisture damage in the crawl space or living area
• Musty odors
• Condensation (“sweating”) on air conditioning ductwork or equipment
• Condensation on insulation, water pipes, or truss plates in the crawl space
• Buckled hardwood floors
• High humidity throughout the house
• Insect infestations
• Rotting of wooden framing
• Increased load on air conditioning and dehumidification systems
Many studies I read documented average energy savings from 15-18%. Another resource also pointed out that many of the crawlspace upgrades qualify for the 15% federal tax credit energy program.
The two most common disadvantages I came across were the cost and the ability to retrofit existing crawlspaces.
Are Vented Crawlspaces Really a Problem?
There was a study performed by the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) involving fungal sampling indoors, outdoors, and in the crawlspaces of 45 homes with traditionally designed vented crawlspace. Air leakage testing determined the connections between the house, crawlspace, and HVAC systems located in the crawlspace.
Results indicated that most of the crawlspaces contained liquid water, moisture vapor, and fungal spores. The houses also contained measurable holes between the crawlspace and the living space, with both natural and mechanical air movements across these openings.
This led to a measured transmission of fungal spores from the crawlspace to the living area. High moisture levels in vented crawlspaces in the Southeastern United States were linked to higher mold counts inside the living space.
There are also a number of excellent scientific articles available on www.BuildingScience.com that explain why traditional vented crawlspace designs may not be the best option for humid climates.

Advanced Energy is an independent non-profit corporation that is governed by a Board of Directors appointed by the governor of North Carolina and the member utilities. The company was set up and still operates to work with member utilities on energy efficiency and conservation projects.

Air Duct Cleaning Bait and Switch Scams
This winter’s weather has been unusually harsh across most of the country – meaning that people are spending more time indoors. That leads many people to evaluate the indoor air quality of their homes and consider services such as air duct cleaning.
Despite the claims of many companies that perform duct cleaning, it has never been proven to have any substantial health benefits. But that doesn’t slow the flood of advertisements that show magnified pictures of dust mites, mold or dirty debris and promise pricing as low as $49.95.
Unfortunately, many air duct cleaning companies use these ads as bait to lure homeowners in, and then switch them to higher priced services that were not clearly explained. The Better Business Bureau states that these “bait and switch” air duct cleaning scams involve dozens of connected companies who have been systematically ripping off homeowners for more than a decade -- to the tune of millions of dollars.
According to NBC’s Dateline: “Over the years, hundreds of homeowners have logged complaints with the BBB, all sounding similar: Once inside a customer's home, technicians routinely mislead them into paying hundreds or thousands of dollars for additional work. Many were told they had dangerous mold. Others had their homes unnecessarily flooded with noxious chemicals. Some said they were afraid of the workmen. All said they were duped into paying hundreds more than the promised $49.99 advertised price.”
That led NBC’s Dateline to conduct an investigation using hidden cameras and senior citizen volunteers. You can check out the video here:
http://www.msnbc.msn.com/id/3032600/vp/41303490#41303490
NBC’s Dateline found that “many of the businesses opened up shop only to disappear within a matter of months, but would then appear again under a different name. Sometimes, it was even hard to determine exactly who owned many of them. The paper trail left behind was limited and sometimes inaccurate. One business was registered using the name of the real owner's dead stepbrother. Another was registered in the name of an owner's bodyguard. Several to convicted felons, one a killer. But our reporting led us to one revealing fact: dozens of the rogue businesses all across the country were run by a rotating list of the same individuals who kept popping up over and over again.”
There are situations where air duct cleaning is necessary or beneficial, and there are many reputable companies that provide fair estimates and do quality work. If you are planning to have the air ducts in your home cleaned, here are some tips from the Environmental Protection Agency on selecting a contractor:

If you are planning to have the air ducts in your home cleaned, here are some tips from the Environmental Protection Agency on selecting a contractor:
- Do not hire duct cleaners who make sweeping claims about the health benefits of duct cleaning – such claims are unsubstantiated. Do not hire duct cleaners who recommend duct cleaning as a routine part of your heating and cooling system maintenance. You should also be wary of duct cleaners who claim to be certified by the EPA. EPA neither establishes duct cleaning standards, nor certifies, endorses, or approves duct cleaning companies.
- Do not allow the use of chemical biocides or chemical treatments unless you fully understand the pros and the cons of the products being used.
Check references to be sure other customers were satisfied and did not experience any problems with their heating and cooling systems after cleaning. - Contact your county or city office of consumer affairs or local Better Business Bureau to determine if complaints have been lodged against any of the companies you are considering.
- Interview potential service providers to ensure that they are experienced in duct cleaning and have worked on systems like yours; they will use procedures to protect you, your pets, and your home from contamination; and they comply with the National Air Duct Cleaning Association's air duct cleaning standards.
- Ask the service provider whether they hold any relevant state licenses. The following states require air duct cleaners to hold special licenses: Arizona, Arkansas, California, Florida, Georgia, Michigan and Texas. Other states may soon require them as well.
- If the service provider charges by the hour, request an estimate of the number of hours or days the job will take, and find out whether there will be interruptions in the work. Make sure the duct cleaner you choose will provide a written agreement outlining the total cost and scope of the job before work begins.

Putting Your Carpet to Work
It’s used to getting walked all over, but now your carpet may be willing to do even more for you. Netherlands carpet manufacturer DESSO has introduced a new type of carpet specially developed to improve the air quality inside buildings.
The new type of carpet, called AirMaster, is eight times more effective in trapping particulate matter than hard floors and four times more effective than a standard carpet, thus greatly reducing the particulates breathed by building occupants. This was the conclusion of a study conducted by the independent German testing institute GUI.
This makes DESSO the world's only manufacturer to offer a product certified with the GUI's golden logo, which means that the carpet is 80% more effective than hard floors when it comes to trapping particulate matter.
The new Airmaster carpet from DESSO is primarily aimed at offices, hospitals, schools and other public buildings. DESSO if guaranteeing that AirMaster provides a significant improvement of the indoor climate and reduction in the risk of health-related problems.
Now if it could only vacuum itself. . .

What You Should Know About Air Sampling for Mold
What is Air Sampling?
Air samples are one of the common techniques used to test for mold. This method quantifies the exposure levels associated with an indoor space and typically compares that level to an outdoor baseline.
Air Matters LLC uses spore trap samples for its air sampling services, specifically the AIR-O-CELL air sampling cassette. This device is designed for the rapid collection and analysis of a range of airborne bioaerosols including fungal species, pollen, skin cell fragments, and insect parts.
How Does Air Sampling Work?
A high volume air pump is calibrated prior to the start of the sample. The AIR-O-CELL cassette is labeled and attached to a tube at the end of the pump. The pump pulls the particulate laden air through the cassette, and the air flow continues out an exit orifice. The length of the sampling period is digitally timed to ensure accurate calculation of the air flow.
The particles are deposited on an adhesive area contained inside the cassette. The AIR-O-CELL cassette is removed from the tubing and sealed. The specific information regarding the sample is recorded on a chain of custody form. After the assessment, all samples and the chain of custody are transported to the laboratory for analysis.
At the lab, the cassette is opened and examined under a microscope. The various particles are identified and quantified. This information is summarized in a report and transmitted to Air Matters LLC.
What Does Air Sampling Tell You?
It is important to remember that air sampling data provides a snapshot of one specific moment in time. Conditions change constantly based on such factors as temperature, HVAC operation, relative humidity, or building activities.
Since there are no widely accepted numerical guidelines regarding mold like there are for other contaminants (radon for example), a thorough site assessment by a qualified professional is critical to interpreting laboratory findings.

EPA Teams with Building Industry Experts on Comprehensive IAQ Guide
Too often, indoor air quality (IAQ) problems result from poor planning, improper design, or inadequate construction methods and materials. If design and construction teams work together to incorporate good IAQ strategies from the start, many of the common pitfalls can be avoided.
The Indoor Air Quality Guide: Best Practices for Design, Construction and Commissioning is a collaboration between the American Society of Refrigerating, Heating and Air Conditioning Engineers (ASHRAE), the American Institute of Architects, the Building Owners and Managers Association International, the United States Environmental Protection Agency (EPA), the Sheet Metal and Air Conditioning Contractors of North America, and the United States Green Building Council, which awards the internationally recognized LEED green building certification system.
The book outlines specific strategies for achieving eight critical IAQ objectives relative to moisture management, ventilation, filtration and cleaning, and source control.
A 198-page summary of the guide can be downloaded free of charge at www.ashrae.org/iaq. The full publication, including a CD, is also available through ASHRAE for $29.
Within the summary, Objective 2 - Control Moisture in Building Assemblies and Objective 4 - Control Moisture and Contaminants Related to Mechanical Systems offer strategies to limit water and moisture intrusion, which directly impact the growth of fungal (mold) species.
The summary guide states in Objective 2 that "Moisture in buildings is a major contributor to mold growth and the poor IAQ that can result. Wetting of building walls and rainwater leaks are major causes of water infiltration."
There is also significant attention in this section given to controlling indoor humidity levels. High humidity supports the growth of mold, dust mite populations, and other biological contaminants indoors that may cause allergies or other health problems for building occupants.
Low humidity levels can dry out mucous membranes. Either way, "humidity conditions also affect people's perceptions of the IAQ."
Objective 4 starts out explaining the important role of mechanical systems in providing good IAQ. It then states "However, since many mechanical systems carry water or become wet during operation, they can also amplify and distribute microbial contaminants." Detailed strategies are discussed for each component of the mechanical systems.
Considering IAQ from the initial design process through the building occupancy will ensure that everyone breathes a little easier.

Are You Suffering from Sick Building Syndrome?
"Sick Building Syndrome" is a term that is used to describe when somebody experiences health or personal comfort effects that seem to be linked to the amount of time spent in a particular building, but they are unable to positively identify a specific cause or health condition responsible for these effects.
These effects may only be felt when in one particular room or area of a building, or they may be experienced throughout the facility. Also, they may be limited to one individual or can affect a large number of building occupants.
The complaints differ and can include many symptoms such as headaches; dry, itching, red or watery eyes; sensitivity to odors; coughing; dry or itchy patches or skin including rashes; dizziness; nausea; or fatigue.
Two things that do seem to be consistent with Sick Building Syndrome are the fact that an immediate cause of the symptoms is not known and that people who are suffering report a relief from these symptoms once they are away from the building.
According to the Environmental Protection Agency (EPA), the following factors are often responsible for causing or contributing to complaints of Sick Building Syndrome:
1. Biological Contaminants
This includes mold, mildew, bacteria, pollens, and insect or bird droppings. These contaminants may breed in stagnant water that has collected around building leaks or in ducts, drain pans, or humidifiers.
2. Indoor Chemical Contaminants
Adhesives, carpeting, upholstery (including fabric cubicle walls), manufactured wood products (particularly press board), copy machines, pesticides, cigarette smoke, and cleaning products may all emit volatile organic compounds (VOC's), including formaldehyde.
3. Outdoor Chemical Contaminants
The outdoor air that enters a building, particularly through poorly positioned air intake vents, doors or windows can also be a source of chemical pollution. Common contaminants may include motor vehicle exhausts, plumbing vents, kitchen fumes, or bathroom exhausts.
4. Inadequate Ventilation
Energy conservation measures and construction methods have resulted in buildings today being more tightly sealed than ever before. As a result, there has been a decrease in the outdoor air exchange. Inadequate ventilation may also occur when the HVAC system is not properly sized, balanced or maintained for the square footage and type of occupancy intended and is unable to effectively distribute conditioned air to the occupants of the building.
A professional indoor air quality investigation is one tool to help identify potential risk factors that may be contributing to symptoms of Sick Building Syndrome.

Resolve to Improve Your Indoor Air Quality in 2010!
So, we are a little half way through January. How are those New Year's resolutions going? Eating right, exercising more, getting enough sleep every night. . . you know these things are good for you. That doesn't make them easy. Breathing -- now that's easy. But what about monitoring what you are breathing into your body each day? That's a little tougher!
The toxins that you breathe in every day (air quality) often go unnoticed simply because they are invisible. Things that are invisible (unlike smoking cigarettes, really bad for you foods, and toxic friends) are easy to overlook. The Kingston Whig Standard offers these tips for improving your personal air quality today:
1. Quit smoking. Cigarette smoke contains known carcinogens (cancer-causing agents) and a host of chemicals. If you can't quit just yet, be sure to smoke outdoors. (NOTE: In North Carolina restaurants and bars, you have no choice but to smoke outdoors. Yeah!!)
2.Change furnace filters monthly. Reduce the dust and allergens in the air by changing your furnace or air conditioning system filters on a monthly basis. Also vacuum intake vents. You can consider having ductwork cleaned by a professional service, too. (NOTE: Air Matters LLC recommends you review the following document published by the Environmental Protection Agency prior to having your ducts cleaned. http://www.epa.gov/iaq/pubs/airduct.html)
3. Fill the house with plants. Plants naturally filter the air and give off fresh oxygen. Plus, they're nice to look at!
4. Avoid pressboard furniture. Many composite wood products contain formaldehyde and other chemicals. These can sneak into the air over time.
5. Use all-natural cleaners. Chemical-laden cleaners don't simply smell strongly, they can actually be very harmful if breathed in. Also, never mix cleaning products (such as bleach and ammonia). It can produce a toxic gas. Lemon juice, vinegar, baking soda, and other all-natural items can be used as very effective cleaners.
6. Vacuum carpets regularly. Carpets and fabrics can harbor dust and other allergens. Some newer carpets are created to reduce allergens, but most carpets should be cleaned two to three times a week, primarily in high-traffic areas and in homes with pets. (NOTE: Air Matters LLC recommends that you invest in a HEPA-vacuum.)
7. Eliminate leaks. Drippy faucets or a damp basement can lead to the growth of mold and mildew. While many types of these fungi are harmless, there are some that are very harmful if breathed in. If you have a mold or mildew problem, call in a professional for a threat assessment and advice on proper cleaning. (NOTE: If you want to confirm the presence and identity of fungal species, that would be Air Matters LLC. . .)
8. Test for hidden dangers. Radon, carbon monoxide, and asbestos could be lurking in your home. Testing eliminates threats and can safeguard your family.
9. Call in a cleaning crew. Regular cleaning can limit the amount of particles floating around in the air. Keeping the house spic-and-span is a way to clean the air as well. Having a regular cleaning service come in can be a way to fit a thorough cleaning into your busy schedule.
10. Dial down the humidity. Run the exhaust fans in bathrooms and invest in a dehumidifier. Mold and mildew, as well as dust mites, thrive in moist conditions.
11. Launder sheets and pillowcases every 10 days. Buy machine- washable pillows and bed linens.
12. Kick out pests. Allergens from roaches are a major cause of asthma, and airborne protein from dried rodent urine is a potent allergen.
13. Air it out. On low-particulate days, throw open the windows and let the fresh air in.
14. Check the venting. All appliances should be properly vented. Make sure vents are free of obstructions. Appliances should be serviced according to the manufacturer's maintenance schedule to avoid combustion byproduct buildup and reduce dust and particulate accumulation.

US Surgeon General and Federal Government on Mold and Healthy Homes
The U.S. Surgeon General's Office, the Centers for Disease Control (CDC), the Department of Housing and Urban Development (HUD), and other federal agencies are coming together to try and help raise awareness on the health effects of poor indoor air quality within the home.
In conjunction with this, acting Surgeon General Steven K. Galson recently released a report titled "The Surgeon General's Call to Action to Promote Healthy Homes". Galson told the media that the purpose of the report was to promote discussions about the importance of healthy homes.
He stated that "We can prevent many diseases and injuries that result from health hazards in the home by following the simple steps outlined in this Call to Action."
The report addresses many indoor contaminants, including mold. It includes many suggestions to improve the air quality in your home such as prohibiting smoking and eliminating exposure to second hand smoke, installing carbon monoxide and radon detection devices, and controlling moisture and water intrusion to reduce the potential for mold growth.
The full text of the report can be read on the Surgeon General's information website at: http://www.surgeongeneral.gov/topics/healthyhomes/calltoactiontopromotehealthyhomes.pdf
