LEED Testing

A & B Environmental Services Inc. is now offering comprehensive Indoor Air Quality (IAQ) analysis to meet the Leadership in Energy and Environmental Design (LEED) Green Building Rating system for New Construction (LEED-NC) as an effective alternative for Flushing Out the building for two long weeks.

We conduct baseline IAQ testing after construction ends and prior to occupancy, using analysis protocols consistent with USEpA, to demonstrate that the contaminant maximum concentrations listed below are not exceeded.

Formaldehyde 50 ppbV Composite wood products such as plywood, particleboard, furnishings, wallpaper, durable press fabrics, paints, combustion appliances, tobacco smoke

Total Volatile Organic Compounds (TVOC) 500 µg/m3 paints and lacquers, paint strippers, cleaning supplies, pesticides, building materials and furnishings, printers, correction fluids and carbonless copy paper, glues and adhesives, permanent markers, and photographic
