The old adage “an ounce of prevention is worth a pound of cure” applies when referring to indoor air quality. So remember to look for low VOC or VOC free choices when purchasing common household products. Currently there’s no standard labeling system for VOCs, but many manufacturers offer a low or no VOC option. Formaldehyde, one of the best known VOCs, is surprisingly common in new home construction. Luckily, it happens to be one of the few indoor air pollutants that can be readily measured. Air monitoring is one approach that can help prevent adverse effects of exposure to volatile organic compounds.

One study on formaldehyde and VOC levels utilizing air monitoring found that “the levels of volatile organic compounds (VOCs) in new homes decreased markedly after 1 year”. This is due primarily to the off-gassing process which diminishes over time. If you don’t happen to have expensive air monitoring equipment lying around, you could always use your sense of smell. Just remember that not all VOCs are detectable with the human nose.

Preventing Exposure to VOCs

Identify, and if possible, remove the source. If it’s not possible to remove, reduce exposure by using a low or no VOC sealant on surfaces and other furnishings emitting chemicals. You should always increase ventilation during the period of VOC off gassing and consider using an air purifier.

Potentially hazardous products often have warnings aimed at reducing exposure to the user. Many people, however, don’t bother to read the label before every use (guilty as charged). If a label states to use the product in a well-ventilated area, go outdoors, open the windows or work in areas equipped with an exhaust fan. You should always provide the maximum amount of clean air flow possible. This rule applies when you are using petroleum-based products, fuels, hydraulic fluids, paint, thinners, cleaning agents and the like. This also applies to your new carpet, new car, air fresheners and a variety of other surprising sources.

Other preventative measures

Safely disposing of empty containers or those with very little product remaining. – Using products according to the manufacturer’s directions. – Buying in quantities that you may consume quickly to prevent additional exposure from seepage or vapors, like paint VOCs, that may escape from poorly sealed containers. – Keeping products out of the reach of children and pets. – Making every effort to utilize integrated pest management techniques when using pesticides. – Never mixing products unless directed on the label. – Choosing low VOC or VOC free products.

Via the Eco Evaluator

The American Council for Accredited Certification (ACAC) requested that Florida Department of Business and Professional Regulation (DBPR) give guidance for those seeking Florida licensing for mold assessor or remediation – who missed the deadline for grandfathering – but have previously taken an ACAC certification examination.  Their response:

Any applicant, who has taken the ACAC proctored examination and passed in any of the categories already approved by Florida as meeting the Florida standards, will be accepted. However, in order to obtain a Florida license in Mold profession, they must also meet the rest of the Florida requirements as stated in Statute Chapter 468, Part XVI, Florida Statutes

The categories of ACAC proctored examinations approved are the CIE, CIEC and CMC for the Florida Mold Assessor and CMR, CMRS and CIES for the Florida Mold Remediator.

Please call the ACAC staff toll-free at 888-808-8381 for additional information.

An easy, no-cost credit

Like the similar credit, IEQc4.1: Low-Emitting Materials: Adhesives and Sealants, it shouldn’t cost you anything extra to earn this credit—it will just take some work. Your first priority should be to specify only  paints and coatings that comply with the credit’s VOC limits, and enforce those specifications on the jobsite. Research low-VOC paints and coatings before construction begins and provide lists of acceptable materials to contractors to help ensure that the right products are used.

Performance should not be an issue

Major manufacturers offer paints and coatings that are just as durable and perform just as well as their higher-VOC…

Verify Your Information

Don’t allow the use of products that merely claim to be “low VOC.” Everyone specifying and purchasing products must actually find the products’ VOC content in grams per liter (g/L), which is usually found on the product’s technical data sheet or material safety data sheet, and compare that number with VOC limits listed for different uses determined by the South Coast Air Quality Management District (SCAQMD) Rule #1113 and Green Seal GS-11 and GS-03.

Only 20% of product cut sheets selected at random need to be uploaded to LEED Online to document this credit although it is best to keep all product cut sheets on file in case the credit is audited.

Do It Yourself Mold Test Kits Earn a Not Recommended Rating from Consumer Reports.

If you see or smell mold, you don’t need a test kit to tell you it’s there. Generally, it’s not necessary to identify the species of mold growing in your home, according to the national Centers for Disease Control and Prevention.

If mold covers an area less than 10 square feet, you may be able to eliminate the problem yourself. Larger areas require a pro. When we tested the kits below for our report, we found significant shortcomings in all of them, flaws that were serious enough to earn each a “Not Recommended” Rating.

Grandfathering Ended Yesterday!

Is Green Really Low VOC?

Just what is behind the LEED Green Curtain?

I do my very best to stay off the soap box when it comes to USGBC LEED and IEQ or more specifically IAQ.  I usually stay clear of this topic but I just can’t avoid speaking up once again.

LEED v3 for New Construction IEQ Credit 3.2   (page 64)

<https://www.usgbc.org/ShowFile.aspx?DocumentID=8868>

Intent of this credit isn’t to confirm, as you may think, the buildings actual use of the USGBC prescribed Low-Emitting Materials described in IEQ Credit 4.1, but to reduce indoor air quality (IAQ) problems resulting from construction or renovation and to promote the comfort and well-being of construction workers and building occupants. As described in the LEED documents page 66,

It may sound the same but until the IEQ Credit 3.2 becomes a Prerequisite it just a nice thought that looks good in print.

If the requirement did become a Prerequisite the sampling method would then need to be enforced.  Yes enforced.  The use of a MiniRae PID in a few locations doesn’t even come close the the methods described in the USGBC .Rating System Updated February 2011.

I have been working with LEED from the very beginning and I have provided LEED

3.2 testing in accordance with the Rating System many times.  I have provided many LEED and Indoor Air Quality presentations and discussions to USGBC Chapters and National Assoc. of Home Builders Chapters discussing these very issues.  The concern with the builders and general contractors is paying for the testing that may actually show that the building has an elevation in one or more of the USGBC Rating System Contaminant Maximum Concentration limits.  This actually happens much, much more that most would admit.  The result is that most simply ignore if not avoid the 3.2 Credit option 2 Air Sampling.

As a result of this avoidance, due to recent developments, and even though USGBC officially does not endorse one method over another,  the USGBC has allowed the use of handheld PID’s to measure TVOC’s.  The USGBC does this even though they have been made aware that using photoionization detectors (PID’s) to measure TVOC’s in buildings does not meet the minimum 4-hour sampling period required in the Rating System page 65.

This was an effort on behalf of the USGBC to encourage more contractors to actually pursue the 1 point in the entire USGBC Rating System that can confirm the use of the USGBC prescribed Low-Emitting Materials.  Something they are currently in serious need of confirming.

I continue to provide the LEED 3.2 point to my clients who are to actually wanting to earn the credit and confirm the buildings IEQ status using the USGBC required sampling methods.

I refuse to change my sampling protocols to those recently being used by others that require only a snapshot of the indoor environment using handheld PID samplers.

I choose not to provide anything less than the sampling methods that meet the USGBC’s Rating System requirements as described on page 65 of the LEED v3 LEED for New Construction launched on April 27, 2009, including an upgrade of LEED for New Construction under the suite of LEED 2009 rating systems. LEED for New Construction 2009 is served by the Green Building Design and Construction Reference Guide.

Pass or Fail the USGBC set their Standard.  I only measure the indoor environment according to their standard and encourage all others to do the same thing.

Go ahead take a peek at what is actually behind the curtain.

The USGBC sampling is described as follows.

OPTION 2. Air Testing

Conduct baseline IAQ testing after construction ends and prior to occupancy using testing protocols consistent with the EPA Compendium of Methods for the Determination of Air Pollutants in Indoor Air and as additionally detailed in the LEED Reference Guide for Green Building Design and Construction, 2009 Edition.

Demonstrate that the contaminant maximum concentration levels listed below are not exceeded:

Contaminant Maximum Concentration

•Formaldehyde 27 parts per billion

•Particulates (PM10) 50 micrograms per cubic meter

•Total volatile organic compounds (TVOCs) 500 micrograms per cubic meter

•4-Phenylcyclohexene (4-PCH)* 6.5 micrograms per cubic meter

•Carbon monoxide (CO) 9 part per million and no greater than 2 parts per million above outdoor levels

For each sampling point where the maximum concentration limits are exceeded, conduct an additional flush-out with outside air and retest the non-compliant concentrations. Repeat until all requirements are met. When retesting non-compliant building areas, take samples from the same locations as in the first test, although it is not required.

Conduct the air sample testing as follows:

•All measurements must be conducted prior to occupancy, but during normal occupied hours with the building ventilation system started at the normal daily start time and operated at the minimum outside air flow rate for the occupied mode throughout the test.

•All interior finishes must be installed, including but not limited to millwork, doors, paint, carpet and acoustic tiles. Movable furnishings such as workstations and partitions should be in place for the testing, although it is not required.

•The number of sampling locations will depend on the size of the building and number of ventilation systems. For each portion of the building served by a separate ventilation system, the number of sampling points must not be less than 1 per 25,000 sq ft or for each contiguous floor area, whichever is larger.

•Include areas with the least ventilation and greatest presumed source strength.

•Air samples must be collected between 3 and 6 feet from the floor to represent the breathing zone of occupants, and over a minimum 4-hour period.
