LEED Indoor Air Quality
LEED O+M: Existing Buildings v4.1 – LEED v4.1 Indoor Environmental Quality Performance
Environmental Efficiency has significant experience in LEED V4 and V4.1 and has carried out LEED Indoor air quality assessments on sites in Europe and Africa.
Indoor Air Quality measurements across the building envelope that are defined as Regularly Occupied. The testing is required as part of the LEED EQc4 Credits.
We offer two options for LEED Indoor Air Quality Testing Kits outlined below. For additional details on methods (USEPA approved only), techniques, reporting limits and more, please contact us.
What we can offer for you LEED Project
LEED V4.1
CO: ISO 4224 EPA Compendium Method IP-3 GB/T 18883-2002 for projects in China Direct calibrated electrochemical instrument with accuracy of (+/- 2% ppm <50 ppm minimum accuracy).
PM 10 & *PM 2.5: ISO 14644-1:2015, Particulate monitoring device with accuracy greater of 5 micrograms/m3 or 20% of reading and resolution (5 min average data) +/- 5 µg/m3
*Projects in areas with high ambient levels of PM2.5 (known EPA nonattainment areas for PM2.5, or local equivalent) must meet the 35 μg/m3 limit, all other projects should meet the 12 μg/m3 limit.
Ozone: Monitoring device with accuracy greater of 5 ppb or 20% of reading and resolution (5 min average data) +/- 5 ppb ISO 13964 ASTM D5149 -– 02 EPA designated methods for Ozone
Formaldehyde and Acetaldehyde: ISO 16000-3, 4; EPA TO-11a, EPA comp. IP-6 ASTM D5197-16
