Indoor Air Quality Testing and Standards for Buildings

LEED v4 & v4.1 EQ Credit: Indoor Air Quality Assessment

USGBC LEED® v4, EQ Credit: Indoor Air Quality Assessment, Option 2 requires the measurement of the individual VOCs in CDPH Standard Method V1.1 plus formaldehyde and total VOCs (TVOC). With LEED v4.1, the Indoor Air Quality (IAQ) contaminate list has been shortened to only 12 VOCs (including formaldehyde) with defined threshold concentration limits that must be met.  The TVOC limit has been removed. Exemplary performance is offered to projects that test for all of the target VOCs specified in CDPH Standard Method v1.2-2017, Table 4-1 and that do not exceed the full CREL levels for these compounds. The test methods include U.S. EPA Method TO-17 for VOCs and TVOC and ASTM D5197 for formaldehyde. Berkeley Analytical (BkA) is ISO/IEC 17025 accredited laboratory with these methods in its scope as required by the LEED credit. BkA delivers rapid turn-around of analytical results to help you meet tight building completion and occupant move-in schedules.

Building IAQ Investigations

Since 1989, BkA has provided industrial hygienists, building engineers and environmental health and safety departments with IAQ testing services tailored to the customers’ objectives. BkA’s support services for IAQ investigations include:

  • Thermal desorption GC/MS analysis of VOCs collected on sorbent tubes by U.S. EPA TO-17 (BkA supplies tubes for your use)
  • Analysis of sampling cartridges for formaldehyde and acetaldehyde by ASTM D5197
  • VOC emission chamber studies of field collected products and materials tailored to project objectives
  • Odor complaint investigations

BkA has 30 years of experience in IAQ investigations. In many cases, we can offer advice on cost-effective sampling and analytical strategies to help you solve IAQ problems and your customer objectives.

Odor Investigations

As a society, we spend on average about 90% of our time in buildings. Not surprisingly, complaints about poor IAQ, such as the presence of annoying odors, are common. Besides being unpleasant, odors can adversely affect worker and student productivity. In many cases, building odors are due to a VOC source that is discoverable by air sampling and analysis.

BkA's analytical reports for odor investigations identify and quantify all of the VOC constituents of air samples down to trace levels. This attention to detail is essential as some chemicals produce objectionable odors at very low concentrations.

BkA also has extensive experience helping building product and furniture manufacturers address odor complaints received from their customers. Product complaints are serious concerns as they have the potential to directly impact sales. BkA uses its extensive chamber testing facilities plus detailed chemical analysis to isolate and to identify the sources of these odors.

Product Selection for Healthy Indoor Environments

Interest in more sustainable and healthy building construction practices is expanding. Testing of products for VOC emissions as part of the design-phase product selection process can help to achieve acceptable IAQ and to avoid unpleasant surprises such as objectionable odors.

BkA has co-authored a report under a NIST contract that provides a detailed indoor air quality architectural specification for use in residential new construction and renovation. The IAQ specification provides best practices for reducing indoor sources of formaldehyde and other VOCs.
