A & B Labs offers 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.
