LEED® Indoor Air Quality Testing

Are You Ready for the New V4 IAQ Test?

To establish better quality indoor air in the building after construction and during occupancy.

The New V4 requirements are as follows:

Air testing now worth (2 points)

After construction ends and before occupancy, but under ventilation conditions typical for occupancy, conduct baseline IAQ testing using protocols consistent with the methods listed in Table 1 for all occupied spaces. Use current versions of ASTM standard methods, EPA compendium methods, or ISO methods, as indicated. Laboratories that conduct the tests for chemical analysis of formaldehyde and volatile organic compounds must be accredited under ISO/IEC 17025 for the test methods they use. Retail projects may conduct the testing within 14 days of occupancy.

Demonstrate that contaminants do not exceed the concentration levels listed in Table 1.

SIMPLE – COST EFFECTIVE – SUSTAINABLE LEED® Air-Sampling and Analytical Program

Upon researching air-sling programs available from other laboratories, the Centek Labs team of analysts and LEED® Certified Professionals aimed to utilize it’s unique capabilities to provide a program that is simple, cost effective, and environmentally friendly. After thorough research the Centek Labs team developed an air-sampling program using our specially treated whole air-sampling canisters and instrumentation while adhering to all requirements set for the by LEED® 2009 for New Construction and Major Renovations IEQ Credit 3.2: Construction Indoor Air Quality Plan—Before Occupancy OPTION 2. Air Testing.

Media Used

1) 1L Silonite-Coated Whole Air Sampling Canister and 4-hour Preset Regulator

LEED IEQ Credit 3 2 Air Testing Sampling Instructions

COMPOUNDS OF CONCERN ANALYZED (via US EPA Compendium) Through One Whole Air Sample

  • TVOC (Total Volatile Organic Compounds) 500 ug/m3
  • CO (Carbon Monoxide) 9 ppm



  • Particulate (PM10) 50 ug/m3

Centek Labs Sustainable Air Sampling Program is Simple

The Centek Labs Sustainable Air-Sampling Program uses less (yet more innovative) media and equipment. Media set up and break down requires no tools or power. Media setup time is one-third the estimated setup time of other sampling programs. Centek Media Set up and Breakdown description (pdf)
